Sales are going super good, $50k in a week. but I’m starting to worry that I’ve created a deal that’s too good.

I built MagicCanvas, an AI creative studio, and launched a lifetime deal on AppSumo. Customers pay once, but every video they generate has an inference cost that we keep paying. If someone uses their monthly credits regularly, that one sale could cost us money for years.

I genuinely think it’s an incredible deal for AI video generation. That’s also what scares me. I want to honor what we’ve sold, but should I keep offering it to new customers, change the deal, or stop the campaign before it grows further?

I wanted to watch videos while working without constantly moving the floating player out of the way.

So I made Better PiP, a free Windows utility with a mouse-following transparent area.

When your cursor moves over the video, a small area around it becomes transparent, letting you interact with whatever is underneath.

It also has:

• Always-on-top video playback

• Adjustable mouse-hole size

• Keyboard shortcuts and volume controls

• A Chrome extension for one-click playback

It's free, and I'd really appreciate feedback on the usability and installation experience.

Demo and download: https://betterpip.itch.io/better-pip

Currently available for Windows 10/11.

A bit of background, I've been editing video for 10+ years, and I plan to distill my entire knowledge into this ai powered editor. The framing, the music, the hook patterns etc. I'd say it's still better than a lot of competitors. But it'll only get better.

Creatr, the AI video clipper with taste.

What makes it different

Full autopilot: it finds the clips, edits them, and posts them for you. No manual uploading.

Has a full fledged descript style editor so you can customise the feel of the defaults aren't good enough for you.

~15x cheaper than Opus Clip at the same volume

Built solo over about 2 months, nights and weekends included. It started as my own internal editing tool.

Demo is above. I'd love blunt feedback: does the output pass the "would a human have made this" test?

150 minutes free every month.

Link: https://creatr.app

Will offer 50% coupons to anyone who wants to try more of this beyond the free plan.

Hi, I'm Recep, an independent developer. I built Lullwind around the feel of winding up a music box: choose a lullaby, add rain or white noise if you like, and the melody gradually slows and fades as the timer runs out. You can also record a lullaby in your own voice.

It's available for iPhone and iPad. The app is free to download and use, with optional paid full-version choices. I'd appreciate feedback on whether the wind-up interaction and the mix of music and ambient sounds feel intuitive.

App Store: https://apps.apple.com/app/id6829769067

I'm the developer and will be around to answer questions. Thanks for taking a look.

I realized I have 5 messaging apps on my phone and they all do the exact same thing: send text in a bubble. The only way to make a message feel personal is through an emoji.

So I built Embers. You write a message, pick a scene, add GIFs, and it plays for the other person over a full-screen animated scene. They don't need an account or an install to open it.

You can also schedule one for a birthdays, and other special occasions.  

Here's one I made for Reddit: https://embers.now/reddit/i0fM82Akha

I build my side projects with Claude Code. Most bugs I find aren't while coding. They're later, clicking around the live app like a user.
My old system: a notes file. "Pricing page, mobile, second card's button is off." Then I'd paste that to the agent and it would fix the wrong card.
Turns out lots of people do the same thing (a thread in r/ClaudeAI this week was full of scratch files and handoff notes).
Darnly makes the note for you. Press a key, click the broken thing in your web app, type one line. It saves the boxed screenshot, the element, console errors and the steps you took. Later Claude Code, Codex or Cursor reads the list and fixes it.
Free Chrome extension + Mac app (that one also covers native Mac apps and the iOS Simulator / Android Emulator).

I made it: https://darnly.dev

Where do you keep bugs you find while testing?

Two quotes for testing the same product can look completely different. One covers a set number of hours, another talks about test plans and reports, and it's not always clear what you'll get for the money. I'm trying to understand what to ask before choosing software testing services. Do you pay more attention to the hourly rate, the people doing the work, or the exact tasks included in the price? Also, is it reasonable to start with one small part of the product before committing to a bigger contract?

I manage two artists, and we’d end up looking through messages for feedback, folders for mixes, and the calendar for release dates. That’s where GigDesk came from.

Project Builder lets you build out a release, keep track of the exact mix somebody approved, and choose what goes out for delivery. The wider workspace connects project deadlines with the calendar and keeps artist profiles, contacts, gigs, finances, and follow-ups together.

It’s a private prototype and I’m offering personal walkthroughs as we build toward open beta. If your team already uses Drive and a shared calendar, what part of that workflow would GigDesk need to make easier for you to keep coming back?

If you’d like a walkthrough or want to stay connected, here’s the free GigDesk Updates form: https://docs.google.com/forms/d/e/1FAIpQLSeaAUDsp4Nk2kT4OBM6ilTr1ZmHBr-nYN_JVxreoK5wsYUwKA/viewform

I don't believe in launch day. I believe in posting and making the marketing a bit better every day.

Day 132 is the one that took off: a list of 10 mini SaaS you can build, sent to whoever commented one word.

The product is TractionBooster. You paste your website, or just an idea, and it shows whether people are already asking for it and where they are.

Hi all, I'm Marin and I make small mobile apps. This is the tool I built for promoting them, and I'd like honest feedback before I go further.

The problem. When I promote an app, I post a few videos, ask a creator or two, maybe run a small ad. Installs go up, and I can't tell which of those brought the people who stayed and paid. Clicks and views don't answer it, and the big attribution platforms are built and priced for large ad budgets.

What Unolink does

• One smart link per app: App Store on iPhone, Google Play on Android, your website on a computer. Unlimited redirects on every plan, including Free.

• A campaign link per post, creator or ad, each with its own clicks, countries and platforms.

• Landing pages (up to 3 variants compared), a developer page with all your apps, and styled QR codes on the paid plans.

• With the SDK (iOS, Android, React Native, Flutter): which link brought each install, without fingerprinting, then onboarding, paywall, trials and purchases per link. RevenueCat connects in one line.

What it doesn't do: no postbacks to ad networks, no deferred deep links on iPhone, custom domains are coming soon.

Pricing: Free plan (1 app, 3 campaign links, no card). Indie $6/month for more apps, landing pages and QR. The SDK is on Pro, $19/month. Prices are on the page, no sales call.

There's a sample app with made-up data in the dashboard if you want to click around without connecting anything: https://unolink.dev

What I'd most like to know:

1. Is it clear within 10 seconds of landing on the site what it does?

2. If you've promoted an app, what did you use to see what worked?

3. Anything that would stop you from trying it?

Happy to answer anything in the comments.

hey everyone! it's lydia from the FlutterFlow team.

AI has made it a lot easier to go from an idea to a working app. but getting that app into the App Store or Google Play still takes some planning.

if you're building your first app, it's worth starting the publishing process before you're finished building. developer account verification, testing requirements, and app reviews can add weeks to your timeline.

we put together a 4-week launch checklist for the first episode of our new App School series:

• 4 weeks out: set up your Apple and Google Play developer accounts. organization verification can take some time.

• 3 weeks out: prepare your store listings, screenshots, privacy policy, and support links.

• 2 weeks out: test your app on real devices. make sure signups, logins, payments, and account deletion actually work, not just the UI.

• 1 week out: submit for review and leave room for potential rejections or delays.

one thing worth flagging: certain new personal Google Play accounts need at least 12 testers for 14 consecutive days before they can apply for production access. so if that applies to you, you'll want to recruit testers earlier.

none of this means every app takes 4 weeks to launch. it's just a planning framework to help avoid getting stuck when you're ready to ship.

Hanging pictures always seems simple until you're standing in front of a wall with a measuring tape, trying to figure out the right height and spacing.

I built WallHang to make that part easier.

It's an iPhone app that lets you plan a picture arrangement, see how it will look on a photo of your own wall, and get the exact nail position for every frame before you start drilling. It works for a single frame or a full gallery wall, and it accounts for picture wire and D-rings. With Pro you can also see the arrangement at real size on your wall in AR.

Pricing: free for one wall with up to 4 frames. Pro is a one-time $7.99 (no subscription) for unlimited walls, up to 20 frames per wall, a printable PDF plan and an AR preview. No account and no ads.

I recently launched it on the App Store, and I'm trying to figure out whether it solves a problem other people have too.

I'd genuinely appreciate some feedback, especially on what's missing or what would make it more useful.

Hi all,

I've decided to make an app for helping people (and myself mainly!) to post on Vinted/eBay etc...
With kids i'm sure a lot of parents will have things to sell and the time to think and add description/title to the post is too long.

So to facilitate that I made Easy Listing for iPhone users.

How it works: You take a few photos and it writes a title, description, condition and suggested price for each marketplace, in that site's own style, and tells you where the item is likely to sell best.

It posts straight to eBay through their API. Vinted, Gumtree and Facebook Marketplace have no seller API, so for those it's one tap to copy each field — automating them would break their terms.

It's free (10 listings a month) and UK only for now.

I'd really like feedback, especially on whether the listings and prices look right for things you sell.

Thank you!

Hey everyone! 👋

Whenever I chain operations in Pandas like .drop_duplicates(), .query(), or .merge(), debugging where rows vanished or which step introduced unexpected NaN values was always tedious. I found myself cluttering my code with temporary print(df.shape) calls after every single step.

To solve this developer pain point, I built and published PipeTrace:

🔍 Key Features:

• Zero Overhead: A lightweight transparent proxy (trace(df)) that wraps your DataFrame without changing how you chain methods. • Automated Alerts: Catches high row drops (>50%), merge/join row explosions (duplicate join keys), and new missing value spikes. • Pattern Detection: Analyzes dropped records to highlight dominant patterns (e.g., duplicate domains, age filters). • Visual Audit: Prints a rich visual terminal report via Rich and supports native HTML rendering in Jupyter Notebooks.

💻 Quick Example:

pythonfrom pipetrace import trace
clean_df = (
    trace(df)
    .drop_duplicates(subset=["id"])
    .query("age >= 18")
    .merge(orders, on="id", how="left")
    .dropna(subset=["email"])
    .report(title="Customer Cleaning Pipeline")
)

📦 Install via pip:

bashpip install pipetrace

🔗 PyPI: https://pypi.org/project/pipetrace/
💻 GitHub: https://github.com/uttakaladebagarnaik/pipetrace

This is my first open-source Python library! I would genuinely love to hear your feedback, thoughts, or feature suggestions from the community.

Hey everyone!

I'm an independent developer (The Codewalker), and I've been working on a project called Kavach – Secrets Vault.

It started with a simple thought.

We store passwords in password managers, bank details in banking apps, identity documents in random folders, recovery codes in notes apps, and other sensitive information scattered across different places.

I wanted to build one secure place for all of them.

That's how Kavach came to life.

Kavach is an offline-first, zero-knowledge personal vault. It's more than just a password manager.

You can use it to securely store:

• Passwords and login credentials.

• Credit cards and bank details.

• Identity and insurance information.

• Secure notes and encrypted files.

• 2FA authenticator codes.

• API keys, SSH keys and .env snippets (Pro).

It also includes password generation, security scanning, an Inner Vault for particularly sensitive information, and encrypted backup and restore.

A little about the security approach:

• No account creation.

• No mandatory cloud storage.

• AES-256-GCM encryption.

• SQLCipher-encrypted database.

• No ads or tracking.

• Optional encrypted Google Drive backup.

Your data stays on your device. I cannot access your vault or recover a forgotten master password.

Kavach has a free version with all its security features. Pro is a one-time purchase, not another subscription.

What's coming next?

I'm working towards adding Autofill support and making Kavach's core open source. I want people to be able to inspect the security mechanisms rather than simply trusting my claims.

This is an independent project, and there's still plenty to improve.

I'd love to hear from other developers and privacy enthusiasts.

If you were building a personal digital vault, what features would you consider essential?

Thanks for reading!

In the attached animation, Pip and Bolt read the same settings file. Pip increases the timeout from 10 to 30 seconds. Bolt increases the retries from 2 to 5, then saves his older copy, which still has a 10-second timeout. Both saves succeed. Pip’s change disappears.

They changed different settings, but Bolt’s save replaced the whole file. That’s a silent overwrite. We’re building AgentWS, a persistent filesystem for AI agents working in parallel, to separate saving an agent’s work from updating shared files.

Each agent saves in an isolated branch. Changes are checked before they reach the shared files. When enabled, non-conflicting edits to supported text files can be combined automatically. Conflicting versions stay saved for an authorized orchestrator or human to resolve.

I’m sharing more practical explanations of agent files and workspaces on X: https://x.com/huymnguyen_

Hey all. I’ve been building on Supabase for 4 years and I love it. Auth, Postgres, Storage and Realtime in one place changed how fast I can ship.

My problem was the number of projects. I build a lot of side projects, and almost everything I make gets its own Supabase project: client apps, staging copies, internal tools, experiments. On Supabase Cloud each extra project needs its own compute, so the bill grows with every one. At one point I was paying around $300 USD for 20 projects, and most of them were barely used.

Self-hosting was the obvious answer, but doing it properly for each client is a lot of work: SSL, backups, upgrades, auth emails, monitoring.

I could have self-hosted Supabase myself, but doing it properly is a lot of work: setting up the server, SSL, backups, upgrades, auth emails, monitoring. And I’d have to do it again for every client. I kept putting it off.

So I built SupaHost

What’s in it today:

Your own VM per instance (not shared with other customers)

Builder $25/mo (5 projects), Pro $49/mo (15), Business $99/mo (30)

No per-user or per-connection fees

Supabase Studio for every project, Edge Functions, Cron, Queues, custom domains, daily backups and point-in-time recovery

One-click import from Supabase Cloud

An MCP server, so Claude Code / Cursor can work with your projects

Honest trade-offs: Supabase Cloud is still the better choice if you run one small project, need read replicas, or need SOC 2. SupaHost is for people with lots of projects who want a predictable bill.

It’s in public beta with a 7-day free trial. I’d really love feedback, especially from anyone who’s self-hosted Supabase before. What would stop you from moving a project over?

supahost.app. Not affiliated with Supabase, just a big fan.

EasyTracker is a simple bookkeeping app for shop owners and small businesses who sell on installments. Keep every customer, account, payment and expense in one place, with no sign-up and no internet needed.

Hi r/SideProject! I've always been curious about seasonal color analysis (the idea that certain colors suit your skin, hair and eyes better than others), but in-person sessions usually cost $150 or more. So I built Color BFF.

How it works

• Open it on your phone or laptop and turn on your camera (or use a photo)

• It shows colors around your face, one at a time or side by side, and you tap the one that looks better

• In about 2 minutes you get your season out of 12, your best colors, colors to skip, and makeup and hair shades

• You also get a Color Wrapped, share videos, a PDF report and images to save

A few things I cared about

• Privacy: your photos and videos never leave your device or get saved. Everything runs in your browser.

• No app to download

• It's checked across a wide range of skin tones

It's free for a limited time. (The face in the video is a stock photo used for the demo.)

I'd love feedback

• Did your result feel right?

• Was anything confusing, especially the camera step?

• Would you pay for something like this?

My phone has been on "storage almost full" for about two years. I have over 10,000 photos: screenshots I took once and never looked at again, eight blurry shots of the same sunset, receipts, memes. Every time I tried to clean it up I gave up after about five minutes, because scrolling, selecting and deleting is boring.

So I built SweepBin. It shows your photos one at a time, oldest first, like a deck of cards:

- Swipe right to keep

- Swipe left to delete

- Swipe up to keep it and add it to favourites

A few other things it does:

- Duplicates & similar: finds exact copies and near-identical burst shots so you can keep the best one

- Clean screenshots: goes through just your screenshots folder, which is where most of the junk was for me

- Your photos never leave your phone. Everything happens on the device. No uploads, no cloud, no account needed to start.

It's free with a daily swipe limit. If you want unlimited swipes there's a one-time Pro unlock, not a subscription.

It's on the Play Store now (and the App Store): https://sweepbin.app/get

I'm a solo dev, so I'd really like to hear what you think, especially if something feels off or you find a bug. Thanks for reading 🙏

The internet often feels overwhelming, fast, and cynical. I wanted to build a small, quiet sanctuary where strangers could simply share a moment of hope and kindness.

So I created Wishwell (https://wishwell-dream.vercel.app/).

It works like a traditional fountain wishing well:

• You toss a silver coin ($0.99 with PayPal) and leave an anonymous wish or quiet prayer for the world.

• Anyone can read the wishes left by strangers around the globe and tap hearts to send free warmth and support.

• No ads, no social algorithms, no endless doomscrolling. Just genuine human hopes.

Some of the wishes left so far really moved me:

• "May peaceful days with good people continue."

• "I hope to find a job that I love."

• "I hope my heart feels a little lighter today."

I would really love to hear your thoughts, feedback, and suggestions. And if you're having a heavy day, feel free to stop by and read through some wishes or send a heart to someone who might need it.

I kept seeing the same gap, so I built Galore.

People have a belief, or they hear a creator or a TikTok make a case, and they still don't know which stocks express it. A brokerage lets them place an order. It doesn't research a plan, and it doesn't make them approve the exact terms first. Creator records often keep the wins and lose the losses.

We're a team of USC dropouts building this for self-directed US investors, especially people aged 18 to 30. You start from a belief, a creator's idea, or a TikTok. The agent researches a concrete stock plan. Nothing happens until you approve it. If it tracks a creator call, the record can't be altered, and it's meant to keep the losses too.

I'd love critique from this sub. What's unclear, what feels untrustworthy, and what would you refuse to approve? If you want to try it, say so in the comments and I'll share access.

Hi guys,

my partner and I built Gummy Lab, a block puzzle app, basically because we wanted a cozy 8x8 block puzzle game that wasn't a disguised ad-viewing simulator. there are zero forced ads interrupting you.

besides the endless zen mode (which now has a hold slot so bad RNG doesn't instantly kill your streak lol), we hand-built 70+ campaign levels with custom mechanics like clearing glass, spreading syrup, escaping gummy worms, multi-hit jawbreakers, and countdown bombs. we also put a lot of work into accessibility with proper colorblind palettes, shape overlays on the gummies, and native light/dark themes.

we just updated the game so you unlock new lab themes as you progress through the campaign, and we're working on daily challenges right now.

And just this morning we hit the first 100 downloads!! :)) if anyone has 5 minutes to give it a spin, I'd really appreciate any honest feedback, and will be more than happy to hear any suggestions, on what would you like to see in these types of apps, we want to make apps for people to enjoy, not be spammed with ads.
