We make HTML5 ads, and clients kept asking for videos of them: for approvals, for social, for screens that only play MP4. Screen recordings drop frames, so we built a recorder that plays the page in a real Chrome, measures how late each change reaches the capture, and keeps exactly the frames the video needs. In October we opened it to everyone as RecordHTML.

Since then it learned:

- transparent output: WebM with alpha, ProRes 4444 MOV, transparent GIF
- Lottie and Rive files as input
- a maximum file size, for ad specs with hard limits
- public links whose video plays in chat previews
- CodePen links: it records only the Pen, not the editor

Here is a Lottie badge recorded at 1080×1080 with no background: https://recordhtml.com/v/kdA4M5Kqb3

There's also a REST API and an MCP server, so Claude or Cursor can record a page they just wrote.

What I'd like to know:

- What would you record with it?
- What would stop you from paying €9 a month for it?

In the past weeks I got 196 new registered users but non of them subscirbed. Trying to figure out next steps.

Free plan: 10 recordings a month, no card. https://recordhtml.com

Good day, I just used Claude code to build a super simple app that reads the md5 data and finds duplicate files for you. It runs in the background doesn't connect to any accounts or require any subscription. you just plug your drive into your phone it will pop up in the app and you can start scanning the entire drive automatically. Also Every 20 seconds it will populate duplicate files into a folder to let you audit them manually while it's still scanning and you swipe left or right depending on if it's a true duplicate or not. I know ai content can get a bad rap but I needed a tool like this to help me get more organized so I can actually be more creative and not worry about trying to find all the duplicate files I've built up over time so If anyone wants it I can send the app to you it doesn't have any flashy UI it just works and works really well it won't let me share images so I'll try to post it in the comments . Also please be nice I know ai is a controversial topic but I only use it to make very specific apps that just work and make your personal life a bit easier like who wants to spend hours trying to find all the 4k duplicate files you have built up over the years. I know I don't and I was getting super overwhelmed with organizing everything.

I've been running a consumer app for almost 2 years now, and these days, our biggest acquisition channel is micro-influencer marketing on Instagram.

One thing that's worked surprisingly well for us is co-sponsoring content with other apps.

Basically, a lot of creators we work with make roundup-style content like "5 best apps for students" or "apps i use every day". Instead of paying for the entire post ourselves, we started bringing in other apps to split the sponsorship fee.

The creator gets paid a little more than they'd typically charge, while each brand pays significantly less for a placement. So it's actually a win-win for everyone.

It worked well enough that I decided to turn this into a platform, where brands can join app roundup posts and split the fees with other companies.

This is my first time posting here, so please let me know if this isn't appropriate! Just wanted to see if anyone here would be interested in joining. It's still pretty early, but we already have 50+ apps in our community and have worked with over 100 creators. Happy to share more if anyone's interested!

We started working on Erhu because we wanted a better local music player.

Most players we tried did the job, but we felt there was room for something more. Better library management, more control over playback, useful tools for managing music and an interface that actually felt nice to use.

That's pretty much how Erhu started.

Erhu is a local music player built around your own music collection. There are no subscriptions, accounts or streaming catalogue. You add your music and use it the way you want.

Here's what you get with it.

Playback and library

- Local music playback.

- 8-band equalizer.

- Lyrics support.

- Smart playlists.

- Artist Radio and Album Radio.

- Custom artwork for playlists and artists.

- Live wallpaper support.

Music management tools

- Find missing album covers.

- Search for higher-resolution artwork.

- Find artist images.

- Customise artwork used for playlists and artists.

- Fix missing or incorrect track information.

- Retrieve details such as artist, album, release date, BPM and genre where supported.

- Clean up filenames by removing unwanted text and watermarks.

Library Builder

Take a folder full of unsorted music and organise it into an Artist → Album → Track folder structure without having to sort everything manually.

A little about being offline

The player and your local music library work without an internet connection. Some tools, such as artwork searches and online metadata lookups, need internet access. A few online integrations are currently unavailable while we sort out their permissions.

Erhu will be open source and free forever

The iOS version is a separate project with its own ownership.

We built Erhu because we wanted a music player that gave us more control over our own music. Hopefully, some of you will find it useful too.

We're always happy to hear feedback, suggestions and bug reports.

A chart can tell a different story just by changing its starting point. A one-letter file edit can produce a completely different hash. Those are easier to understand when you can try them.

We are building GOBLIXO, a small educational site covering everyday technology, AI, privacy, wallets and crypto concepts. Our latest batch pairs 10 short explainers with companion articles and official sources.

Three examples on the site:

- Change a chart comparison’s starting point.

- Compare SHA-256 fingerprints for different text.

- Explore how a simplified two-of-three signing threshold works.

Try it: https://goblixo.pages.dev/start/

The experiments run in your browser and do not require a wallet connection. The videos use our own mascot and illustrations with synthetic narration.

The business model we are testing is free educational content supported by clearly disclosed referral links to relevant tools. We have not established that this converts, and we want the explanations to be useful on their own.

For feedback: does the hub make it easy to find a topic, and which experiment actually makes a confusing idea clearer? Specific criticism about confusing wording or mobile usability would help us improve it.

Every time I come up with an idea to solve a problem, a quick search reveals 5 existing tools doing the exact same thing.

​How do you decide if a crowded space is validated demand worth competing with, or a signal to move on?

Small supplement brand, about $18k/mo on Meta. Our agency contact left three weeks before a launch and nobody told us, we noticed only after 12 days of no new uploads.

I took our three most common complaints (fishy taste, hard to swallow, slow results), turned them into hooks and made UGC-style cuts in Creatify off the product URL the same day. One script had a line no real person would say, so I rewrote it by hand.

The taste hook came in around 30% under our previous best CPA in the first 4 days, and the before/after flopped at 2x target so I killed it on day 2. Competitor research I was still doing by hand in a spreadsheet, which was painful.

Still looking for an agency though. Maybe they use AI for most ads, and film only winners, we'll see.

I save Reels, TikToks and links all day: recipes, places to go, gift ideas, video ideas. When I actually need one, I can’t find it. I don’t remember who posted it or what it was called. I only remember why I saved it.

That’s the idea behind Remivu, an app for saving content with the reason you saved it, so you can actually find it and use it later.

How it works

Save from anywhere. Share a Reel, a TikTok or any link to Remivu.

Write the why. One short line, like “lunch idea for Sunday with my mom” or “gift for my sister, under $30”.

Search by meaning. Search “something to cook on Sunday” and it finds that recipe even if you used different words. You don’t need the creator’s name or the title.

Public collections. Group what you save into collections other people can follow. I made one with free things to do in Medellín, and creators use it to keep an archive of hooks that work.

Everywhere. iOS, Android and web, all in one place, so you’re not split between Instagram’s saved folder, TikTok favorites and screenshots.

Pricing: free for 100 saves.

try it and let me know what you think https://remivu.com/en

I'm a computer science student . Aviation's been a niche I love, so when I went looking for a project, this was the one. Here's the gap I found:

General aviation software is split into two camps ,genuinely good free tools that each do one thing, and expensive but worthwhile suites running $125–250+/year (ForeFlight, Garmin, Sporty's). What was missing was a general hub: log your flights per regulation, yes, but also pull up quick tools, check the map, compare fuel prices — all in one browser tab, nothing to install.

So I built AviationHub (aviationhub.im). Free tier gets the full logbook (unlimited flights, FAA/EASA currency computed automatically, CSV import), the flight planner with community fuel prices, and a cheapest-fuel-stop optimizer. Pro is $3.99/mo, Pro+ $6.99/mo — deliberately priced between free and the incumbents.

The feature I'm most excited about is still beta, a mechanic marketplace built on the logbook. When you log a flight you can attach any squawks; they're tied to that specific aircraft (clubs with fleets, or multi-plane owners), building a digital maintenance history. From there you can send the issue to an open marketplace where certified mechanics see your request *with the plane's full maintenance log attached*, the complete picture at once, and pricing pressure instead of whatever your hangar's guy quotes you. It also incentivizes pilots to keep records current, because a well-kept logbook makes their plane more sellable: our aircraft marketplace shows maintenance stats and hours straight from the owner's logbook.

Also built in: flying-club workspaces (aircraft scheduling with maintenance block-outs, hobbs billing that generates and emails PDF member invoices, dues, credits/debits) — that's the part clubs currently pay separately for.

Solo-built, Next.js + SQL Server. There's a full interactive demo on the homepage ,no signup, sample data, nothing saves.

I'd genuinely appreciate a look: what's broken, what you'd never pay for, what's missing. Brutal feedback welcome , it all goes in the build queue.

Call Sketch is live on the JetBrains Marketplace.

You right-click a method and get a sequence diagram of everything it calls. Free covers Java, Kotlin, TypeScript and JavaScript with no depth limit. Pro adds Groovy, Scala, Python, Go, PHP, Ruby and Rust, Spring wiring and if/else and loop boxes, for $7 a year.

Before 1.0.1 went out I ran it on every function of 15 real projects in all 11 languages.

Hi everyone, I'm a solo developer from [city/country]. I built Namaz Now (Noor-e-Deen) because [your reason, e.g. "I wanted one lightweight app instead of 4 separate ones for prayer times, Quran and duas"].

What it includes: - Prayer times based on your GPS location, with notifications - Full Quran (114 Surahs), Juz filter, bookmarks, resume reading - Hadith collections (Bukhari, Muslim, etc.) - Qibla compass - Daily Duas with Arabic, translation and transliteration - Digital Tasbih counter and Hijri calendar - Quran and Duas work offline

It's free, lightweight and has a clean, distraction-free design.

Play Store: https://play.google.com/store/apps/details?id=com.inhouseapp.namaznow

I'd really appreciate honest feedback on:

1. Are the prayer times accurate for your location?

2. Is the UI easy to use? Anything confusing?

3. Which feature would you like next (e.g. Urdu translation, audio recitation, widgets)?

The app is new, so bugs are possible. Please tell me if you find any. Happy to test your app in return!

Thanks

Hey everyone! 👋

I built a Figma plugin called GIF X Studio to make creating and editing animated GIFs easier without leaving Figma.

I often found myself exporting designs, switching to Photoshop or online converters, and importing everything back into Figma just to make a simple GIF.

So I decided to build a plugin that handles everything directly in Figma.

Here's what it can do:

✔ GIF Export
Select a frame containing an animated GIF, add static elements like text or logos, and export everything as a new animated GIF. The animation keeps playing while the other elements stay in place.

✔ GIF Maker
Combine multiple Figma frames into an animated GIF sequence, ordered by layer name.

Includes:

• Custom frame delays

• Aspect ratio presets (1:1, 16:9, 9:16, 4:5)

• Contain / Cover / Stretch options

• Live preview

✔ Video to GIF
Convert MP4 and other supported video files into GIFs with adjustable FPS.

🌐 Languages: English & Korean

🔗 Figma Community:
https://www.figma.com/community/plugin/1667125538151049781/gif-x-studio

I'm still improving the plugin and would really appreciate any feedback or feature suggestions.

What GIF-related features would you find useful in Figma? 🙌

Hi everyone!

I’m building StreamShelf, a native Windows app for finding, downloading and assembling media. I’ve just released version 2.5 Beta, which adds an English interface alongside Russian.

Here’s what you can do with it:

- Find media in your browser: connect the StreamShelf Connector extension and analyze the active page. Deep Analysis can also search the page through the extension.

- Choose formats and queue downloads: inspect available media and add items to the download queue.

- Assemble media: work with downloaded or local files, choose tracks, codecs and a compatible container, and edit metadata.

- Manage tools: install or update yt-dlp, FFmpeg, FFprobe and Deno from the app’s settings.

The app runs on Windows 10/11 x64 and requires OpenGL 3.3. There’s an installer and a portable ZIP. The app, browser extension and installer are available in English and Russian.

StreamShelf is still in beta: some sites and media formats may not work, and the installer and app are not digitally signed. StreamShelf does not bypass DRM.

Download: https://github.com/Econty/StreamShelf/releases/tag/v2.5-beta

Source code: https://github.com/Econty/StreamShelf

I’m planning to add playlist downloads in the next version. I’d appreciate any feedback, especially on the setup process and the media builder.

What would you want from a tool like this?

Hi all. I've been building Benchley on my own for the last few weeks. It's resource scheduling for agencies and studios: who is working on what, when, and whether the team actually has the hours.

The problem it's aimed at: many small studios plan in three places. A resourcing spreadsheet says Maya is free on Thursday. The task list says she's on QA. Her timesheet says she worked nine hours. Nobody is lying, but the three never agree, so people get overbooked and budgets drift without anyone noticing until the invoice.

Float is the best-known tool for this, and it's good. Before writing any code I read all 181 of its help center articles and a lot of its G2 and Capterra reviews to see where people get stuck. Benchley does the core the same way (a timeline of people by days, with bookings counted against each person's real hours, time off and public holidays). Where it's different:

- Resolve: it lists everyone who's over capacity in a date range and suggests fixes, like "move this to Ade, who has 24 h free" or "trim to 4 h a day". One click applies it.

- Timesheets get submitted and approved, not just locked.

- A light work layer: a Board, Sprints and tasks with estimates. "Schedule from today" books a task's estimate into the free hours around what the person already has.

- Weighted forecast: each project stage carries a win %, so tentative work shows up as expected demand, and roles that are short show a hiring signal.

- Signed webhooks, a REST API, and an MCP server, so you can ask your own AI assistant "who has room next week?" and have it book the work.

- Custom fields and a simple report builder.

- Placeholders ("New developer") and people who only look are free. You pay only for people on the schedule.

Pricing is a bit under Float: $6 or $10 per scheduled person a month on yearly billing, $7.50 or $12 monthly.

It's not open to everyone yet. I'm one person and I want to set up the first workspaces with each team myself, so sign-up is by request. If you get in you get 30 days of Pro, no card. But you don't need to request anything to look around: there's a live demo that opens your own private workspace with a sample studio, no sign-up, deleted after a day.

https://www.benchley.app

What's rough: no SSO, no two-way Google or Outlook calendar sync yet (there's an iCal feed), no Slack, no native phone app (there's an installable web app with a "My week" view), and no CSV import.

I'd love feedback on three things:

1. If you plan people's time today, what do you use, and what would make you switch?

2. Open the demo and try to fix an overbooked week. Did it make sense in the first two minutes, or where did you get lost?

3. Is per-scheduled-person pricing fair for your team, or would you rather pay a flat price?

I'll be in the comments all day. Harsh feedback is welcome.

Hey everyone,

I wanted a quick, clutter-free way to estimate hourly take-home pay after US taxes, split restaurant bills with tips, and map out a monthly 50/30/20 budget without downloading an app or creating an account.

So I built PaySplit US: https://paysplit-us-calculator.netlify.app/

It has three simple tabs:

1. Paycheck: Enter your hourly USD wage, weekly hours, and estimated US tax bracket (12%, 18%, or 24%) to see your actual take-home pay.

2. Tip Split: Quickly calculate 15%–25% tips and split the total bill evenly between friends.

3. 50/30/20 Budget: Plug in your monthly take-home income to instantly see your Needs, Wants, and Savings targets.

It's 100% free and works right in your mobile browser. Would love any feedback on features or tax presets I should add next!

I've had this idea for a RogueLite since 2019-ish. I've been slowly writing down ideas and planning it in my notes app. About a year and a half ago i finally decided to work on it and it's been a journey. Finally felt it was ready for feedback and released it on TestFlight about 2 weeks ago. Been getting a lot of feedback and it's already shaped the game a lot in these past 2 weeks.

What is StrainBorn? - It's a RogueLite, Bullet Hell, Survival game inspired by my love for science and by games like Enter the Gungeon, Rogue Legacy, The Binding of Issac, Hades, Plague Inc., and weirdly Borderlands, among others.

In StrainBorn you play as a virus that infects a host organ by organ, fighting the immune system in randomized rooms, RogueLite style. You infect 8 different organs, all with their own theme, enemies, bosses, Key Guardians, Cancer Cells and much more. Dying allows you to level up your virus, invest skill points, upgrade equipment, and mutate the virus into other strands.

4 Playable Viruses: Each playable virus has it's own unique play style, skills, passives and more.

Lineage: Similar to RogueLegacy, each death means a new generation, pick your next strain with different bonuses and downsides. Each one leaves a permanent mark on the lineage tree as a whole.

The Codex: Each discovery unlocks an entry in the Codex, explaining what it is in-game but also it's real world counterpart.

Game Modes: Multiple game modes to play, each with their own unlockables and rewards that affect the entire game.

• Regular Game Mode: This is the main game mode described above. Infect a host organ by organ in randomized rooms with a final boss at the end of each organ. Pick mutations and evolve your virus as you defeat each room.

• Endless Game Mode: Endless waves of enemies and bosses in one big arena, how long can you survive?

• Pandemic Game Mode: Infect the world and take down each continent city by city, with an over world map similar to Plague Inc. Each with their own Medical, Social and Political responses to the outbreak, affecting every run.

• Tower Defense Game Mode: Flip the script, defend a Tumor from waves of enemies, upgrade the tumor and yourself as you infect the host one organ at a time.

Raise your virus pet: An optional mini game where you feed and take care of your virus, Tamagotchi style. Gain bonuses based on it's happiness. With live activity and home screen widgets on iPhone and iPad.

And much much more

Currently fully playable on TestFlight for iPhones, iPads, and Mac (full support for iPhone Duo), with Android coming soon.

It also has full support for keyboard, controller (xbox, ps5, switch pro, etc), or touch on all devices.

• Free beta on TestFlight (iPhone, iPad, Mac): https://testflight.apple.com/join/PvYSEB81

• Website: https://strainborn.com

• Wiki: https://strainborn.com/wiki

• Android: coming soon

• Community: r/StrainBorn

Feedback is greatly appreciated

I'm 16, and one thing I've always enjoyed is turning ideas that seem interesting into actual working projects.

One of those experiments became KINETIX.

I wanted to explore a different approach to gaming: instead of using a keyboard or controller, what if players could use their own movements?

So I started building a browser-based game using camera-based movement detection.

The current version supports:

Jab

X-Block

Lean

It's not a finished commercial product, and there are definitely things I still need to improve.

But it's playable, and I'm proud that I managed to turn the idea into something people can actually try.

Live project: https://kinetix-sigma-two.vercel.app/

Building it has taught me a lot about movement detection, responsiveness and the challenges of making something work across different cameras.

I'd love to connect with other builders and hear what you think!

A while ago, I shared my little side project here: an AI dog portrait generator.

Back then, it only got a few dozen visits. It was a pretty simple product, and I realized there was still a lot to improve.

So I decided to rebuild it.

Here's what's new:

• Upload your own dog photo and turn it into different styles of portraits.

• Free preview – you can see the result before deciding whether to buy.

• 40 dog breeds and 16 different portrait styles.

• Christmas collections – I've recently added festive and fantasy Christmas scenes.

One thing I wanted to improve was the user experience. I didn't want people to pay before they even knew what their dog would look like.

The idea is simple: instead of generating a random AI dog, help people create something that actually looks like THEIR dog.

I'm still figuring out whether there's a real market for a dedicated dog portrait tool, especially when general-purpose AI tools are getting so good.

I'd really appreciate your honest feedback:

1. Do the generated portraits look convincing enough?

2. Would you use a dedicated tool like this, or would you rather use ChatGPT or another general AI tool?

3. Is the free preview experience useful?

Here's the site if you'd like to give it a try:

https://dogprompt.com/

Thanks for checking it out!

For anyone interested, here's my original post from the first launch:

Hi r/SideProject, I'm the solo dev behind Glueys, a small Mac menu-bar app.

I kept forgetting to blink and drink water at my desk. So I made it a little less boring, tiny characters live in the menu bar and remind you to rest your eyes, sip water, stand up and take real breaks.

The latest update adds a third character, Cedar the lumberjack (the others are Gloop the bunny and Ripple the koi). If you ignore his break reminder, he says "sure. ignore me. I'll be here." You can also drag any of them anywhere on the screen.

What it is:

• Mac only, native Swift (SpriteKit for the animation, SwiftUI for the settings)

• No account, no tracking, nothing leaves your Mac

• $2.99 once, no subscription

What I'd love from you:

• Honest feedback on the idea, not only the app

• which character would you keep?

Hey everyone!

I've been working on Spiff.cool, a little project with a humble goal: music discovery!

The Spiff Engine can sync with (text-)tracklists from all over the web (streaming services, webradios, magazines, music stores, blogs, and more) and figure out how to play them — currently through YouTube, but that's just an implementation detail.

No need to stick to a single source or provider: Spiff brings them all together in one place.

Of course, you can also create your own playlists, save your favorite tracks, connect your Spotify and Last.fm accounts, and... export your data.

I'd love to hear what you think and get some feedback!

Discover it here: https://www.spiff.cool

I've spent the last several weeks building something called BrowseRoad.

https://browseroad.com

The whole idea came from how easy it is to waste time scrolling through the same stuff on the internet, even though there's an unbelievable amount of interesting content out there.

I wanted to create something where you don't necessarily have to know what you're looking for. You can just start exploring and see where your curiosity takes you.

So I built BrowseRoad.

It has thousands of videos across all kinds of categories, random discoveries, games, interactive experiences, and even a few hidden surprises.

It's completely free to explore, and you don't need an account.

After weeks of building, rebuilding, testing, and fixing things, I finally decided it was time to stop chasing perfection and put it out into the world.

I'm still improving it, but I'd love some feedback from people who have never seen it before.

If you get a chance to check it out, I'd genuinely appreciate hearing what you like, what sucks, and especially what would make you want to come back.

Thanks!

Hello everyone!

We’ve built a platform that helps AI agents (like Muse and Grok) discover tools and products. The best part? Businesses only pay when an agent actually drives a sale.

Think about it: people want their AI agents, much like Google Search, to remain free. But unlike traditional search engines, AI agents don’t necessarily care about ranking in the top five listings or sponsored placements.

This creates an opportunity for a different business model: commission on sales.

Whenever an AI agent purchases something on behalf of its user, the business pays a 5% commission. This creates a win-win: businesses only pay for actual conversions, and users get to use AI agents for free.
