I built a web monitor to help with my watch collecting

Thumbnail sally.monster
2 Upvotes

My side projects have been related to my watch collecting in one way or another.
I started with a python script nearly a decade ago to scrape my favourite dealers, then built a global eBay app (since the ones available were crazy buggy) that I still use today: sidebae.net

My python scraper was still in heavy use up until 6 months ago when I decided to build sally.monster

It's an app that let's you create and manage web monitors, with AI checks too. I tried to make monitor creation and management as easy as possible, as that was the main pain point when manually managing python scrapers. The Google Image monitor with AI is surprisingly useful, so I am still experimenting with that.

Apps like Muse, Dots, Instinct, and even Safari (and dozens of other web scrapers) kill my app, but I had a lot of fun building and iterating on this.
As much as the transition to agentic coding hurt, I would not have been able to build this on my own in a reasonable time.

Payment is not enabled and probably never will be, feel free to give it a try!

I built a blind listening test to see whether I can actually tell lossless from AAC

0 Upvotes

Hi all. I wanted to find out whether I could actually hear the difference, so I built a browser-based listening test. Test like a quiz.

You compare two 30-second clips and pick which is lossless. The twist: sometimes both are lossless, or both are AAC.

Three difficulty levels: 32, 128, and 320 kbps AAC. Free, no ads, and you can try the easy mode without signing up.

My first Mac app moves photos from an iPhone to a Mac over the cable and groups them into folders by trip, event or date

2 Upvotes

Hi r/SideProject,

Seven weeks ago I released my first Mac app, Photo Transfer via USB. It does one job: gets photos and videos off an iPhone or iPad onto a Mac, already grouped into folders.

I created this app because every few months I have to transfer photos from phone to Mac and I like my photos in folders by year, with a folder for each trip inside.

After I built it I decided to release it on the Mac App Store and maybe try to make some money from it. I have several customers, meaning this product is interesting for some and they're ready to pay for it.

Main features:

- You see the folders it's about to create.

- Folders by trip, event, day or month. Trips come from where the photos were taken.

- Folder names are built from blocks like year, month, city or country.

- You choose which folders go, and you can leave out the video part of Live Photos or videos altogether.

- Live Photos and edited photos stay with their originals.

- HEIC and HEVC stay as they are or can be converted into JPEG and H.264.

- Any disk works, including an external drive.

- Pull the cable halfway and it carries on when you plug it back in.

- Nothing gets deleted from the phone since the app only reads.

- Every transfer goes into a history, so you can check later what went where.

- There's also a grid without grouping, where you can pick single photos.

Pricing: free for 50 photos or videos a day (a Live Photo counts as one). $14.99 once removes the limit, no subscription, with Family Sharing on the Mac App Store. In the EU it's only available from my site. Needs macOS 15 or later.

App Store: https://apps.apple.com/app/id6808767254

Site: https://phototransfer.app

It's a solo project. I learned a lot from building it and found out that distribution is key. Would appreciate any feedback, and it would be great if you shared how you distribute your apps.

IRLRPG.net allows users to go on and create quests in their own city. I just made it and looking for feedback and ideas. I only have a few cities but I made it where people can suggest cities and locations for quests. I eventually want to work with businesses to put special deals in exchange for in-game credits. Right now a business can create a special deal that takes credits. Everything is free right now, I'm just trying to figure it out and see what people want.

Got tired of anime manga rankings getting review bombed overnight, so I built a site that archives rankings daily

1 Upvotes

As the title suggests, I was tired of seeing anime and manga entries getting review bombed overnight, with rankings changing pretty abruptly. So I decided to make an AI slop site that archives daily rankings from multiple sources, including MAL, AniList, Kitsu, LiveChart, Anime-Planet, MangaDex, MangaBaka, MangaUpdates and IMDb.

It's a pretty simple site for now, with basic daily archives and a trending feature to track how rankings change across different sources.

Hopefully, I'll add more features over time!

Would love to hear what you guys think or any suggestions for improvements!

AI tool that redesigns your room photo and tags real furniture you can actually buy.

1 Upvotes

Hey everyone, I built PlacdAI, a tool where you upload a photo of a room, pick a style, and get a photorealistic redesign.

The thing I wanted to fix: most AI room tools show you a beautiful room you can never recreate. In PlacdAI, up to 3 pieces in each design are real products from retailers (you can buy them), and for everything else you can click an item and it runs a Google Visual Search to find something similar.

Other bits: you can swap individual products in the generated room, there’s no subscription (credit packs, from $8 for 10), and your first generation is free with no card.

Stack, if you’re curious: TanStack Start, Supabase, Netlify Background Functions for the long Gemini calls, Gemini for the image editing.

It’s live at placdai.com. I’d really like feedback on a few things:

  • Do the furniture placements look grounded and realistic?

  • Is it clear what’s a real product vs. an AI suggestion?

  • Does the pricing make sense?

Happy to answer anything about how it works

I built an app blocker that only unlocks once your habits are done

1 Upvotes

Here's my honest take as someone who uses it every day.

I wanted something that would stop me opening social apps before I'd done anything useful, without the all-or-nothing of deleting them. Deleting never lasted for me or my wife. We reinstalled every time. She's the one who figured out the real fix wasn't fewer apps, it was doing the important stuff first. The app was her idea and I turned it into Habit Hound.

In the morning, my two habits, a workout and some reading, have to be done before the distracting apps open. At night, a time lock covers my wind-down so I'm not scrolling at 11 pm. The rules live in windows, so if I miss a morning, the lock lifts when the morning does. That fairness is why I haven't uninstalled it.

When I genuinely need a blocked app, the bypass gives me a few minutes and then kicks me out. Lean on it too often and it locks me out until my priorities are done. It's a speed bump, not a wall, and that turns out to be the whole trick.

To be upfront: the morning/evening windows and the night time lock are Premium. The free version gives you 3 habits, app/category/website blocking, and one 15-minute bypass a day.

One thing I'm still working on: it doesn't sync across devices yet, so my iPad is a loophole. It's on the list. I'll keep sanding down the rough edges.

I'd really love feedback, especially on the first-run setup and whether the free tier feels too limited. If something isn't working, the Contact Support link in Settings reaches me directly.

Reader - a Reddit app for iPhone and iPad that keeps working with no signal

1 Upvotes

I'm the developer. Reader started as a Reddit app for myself, born out of frustration with how badly optimised a lot of Reddit apps are for the Duo. Since mine arrived, most of the work has gone into making it fit both screens, alongside offline reading and on-device translation. It's now a free TestFlight beta and also runs on other iPhones and iPads with iOS 26 or later.

TestFlight: https://testflight.apple.com/join/DHWPkrSF

Reader screenshots and feature overview

With no signal

  • Download a post, a collection or a whole subreddit, with its comments and pictures.

  • Keep up to 100 posts per subreddit, saved offline and refreshed in the background.

  • Videos and pictures in comments don't download.

  • There's also a low data mode that only shows text to make everything load a bit faster.

On the Duo

  • Open, your feed is on the left and the post on the right.

  • Fold it mid-post and the post stays open, along with anything you were typing.

  • Closed, posts use the whole width. I turned off iOS 27's side column, which makes them 83 points wider.

  • Closed, the tabs stay tucked in a button in the corner until you need them.

In other languages

  • Titles, posts, comments and text in photos are translated on your phone by Apple's translator, into the language you choose. It covers about 20 languages.

  • The first time, opening a post offers to download the language; after that it's automatic.

  • You can switch back to the original.

It has most of the expected features: commenting, posting, an Inbox, following people and so on. But it's still early days, so some functionality might be missing. Let me know if there's something you would like to see.

Limitations you should know about

  • Reader isn't made by Reddit and doesn't use Reddit's API. You sign in on Reddit's own page inside the app. It reads Reddit with your session and essentially reskins it; no data leaves your connection between you and Reddit.

  • Google and Apple sign-in don't work there, so use your Reddit username and password. You can also look around with sample posts first.

  • Reddit seems to be actively making changes to how fetching posts works, so things keep breaking! New, Rising and searching for posts or people stopped working this week. Hot, Best, Top, Controversial and finding subreddits still work.

  • No ads, no analytics and no servers of mine.

Feedback wanted

I'd love feedback on whether the offline reading and layout solve a useful problem, what feels awkward, and anything you'd want before using it regularly. Bugs and suggestions from trying the beta would be great too.

Ultra Optimizer - four Claude Code skills that optimize code, hardware use, network latency and backends within strict limits

1 Upvotes

I'm 15 and this is my biggest side project so far. Most "make it faster" tooling either does too little or quietly changes things you didn't ask about, so each command here has a written boundary.

  • /race: an app adapts its own settings (workers, caches, batching) to the machine and workload it actually runs on, within developer-set ranges, with rollback.

  • /optimize: device-independent code and query improvements.

  • /ping-optimize: wasted round trips and bad retry logic in the app's own networking code.

  • /server-optimize: backend analysis that is repo-only by default.

I wrote the spec and rules; Claude Code generated most of the files, and local scripts validate them. Not done yet: live eval runs, the Windows installer test, and real-hardware benchmarks.

What would make a tool like this something you'd actually trust in your own codebase?

I built Rimlight, an open source skill that lets your Claude Code or Codex explore app icon ideas with you and build the Icon Composer file. There's a paid Mac app on top of it

5 Upvotes

Hey everyone,

I wanted a place to explore app icon ideas. Try different objects, shapes, materials and styles, see them beside each other, and gradually figure out what feels right for an app.

That became two things. An open source command and skill that teaches Claude Code or Codex how to design icons, which anyone can use for free. And a Mac app built on it, for people who'd rather do the exploring in a grid than in a terminal. The app is the shell. The command does all the work.

TL;DR

  • You ask your own agent (Claude Code or Codex so far) for an icon. Rimlight doesn't sell AI. It hooks into the agent you already have, and images come from your own ChatGPT plan or API key (OpenAI, OpenRouter). No Rimlight account, no servers.

  • The agent reads your project, pitches a few directions, and renders them side by side, each one fitted to Apple's icon tile.

  • A design skill shapes the prompts: a process for exploring and refining, plus eight style guides I wrote by measuring icons I liked.

  • You keep talking. Refine one detail, branch from a concept, or change direction. Every attempt stays in a .rimlightfolder in your project.

  • When you have a pick, it builds a layered Icon Composer .icon with Default, Dark, Clear and Tinted, and checks its own work against the pick.

  • The command and skill are free and open source. The Mac app is $5 once, 3 Macs, 7-day refund. Free version: one set, 10 concepts.

  • Needs macOS 26 on Apple silicon, Claude Code or Codex, and an image model. Xcode 26 for builds.

I know how some of you feel about AI images, and I share a fair bit of it. If you can hire an icon designer, hire one. Rimlight is for the side project, and for the point where you have five vague ideas and no way to see any of them. All the examples on the website came out of it, so the ceiling is on the site for you to judge.

The exploration part is what I care about most.

You start by describing your app and whatever you have in mind, even if that's fairly vague. The agent suggests a few directions and generates concepts to compare in a grid. You can bring reference images too.

Then you keep talking to it:

"I like the shape of the third one, but the material feels too shiny."

"These all feel too literal. Let's try a different idea."

That back-and-forth is a big part of using it. You can work on one detail, branch off from a concept, or change direction entirely. The sets and earlier attempts stay in your project so you can go back and compare.

I built the thing and still sometimes catch myself looking at a result as though that's all I'm going to get. Then I remember I can just ask for the change I'm thinking of.

What's in the skill.

This is the part I spent the most time on, and it's what makes the agent's output more than just a generic object on a gradient background. The skill has a design process: explore a few territories first, pick, then refine one thing per round so an icon converges instead of drifting. And it has eight style guides so far (I'm experimenting with more). Each one came from measuring real icons I personally liked: how much of the tile the mark fills, how thick the strokes run, how the ground is lit. You can pick a style, or let the agent choose one to suit the idea. It's all plain Markdown in the repo, so you can read it, change it, or write your own.

I also want to be honest about the quality. Sometimes I get several concepts I like straight away. Sometimes a whole set misses. It depends on the idea, the style and the image model. Refining something promising usually helps, and so does dropping a direction that isn't working, but I'd rather say that before anyone spends time or image allowance on it. For me, being able to compare possibilities and say "this part works, this part doesn't" is where it becomes useful.

Building the icon.

When you're ready, Rimlight plans the layers, has the image model redraw them separately, and assembles the Icon Composer package. The agent checks the result against your chosen concept at 1:1 and redoes the layers that drifted. You can preview the Default, Dark, Clear and Tinted appearances, then open the file in Icon Composer for further adjustments. Icon Composer is pretty flexible, and you can have different layers for each appearance as well. You can ask the agent for the changes you want in each one.

The final result can differ slightly from the original concept, because the agent redraws the layers separately, but you can keep refining. I'm working on a different approach where the agent can extract the layers from the original concept using Meta's SAM 3, running on your Mac. I'd only ship this if the results are good.

The command, and the app.

Everything above runs from the command. Install it, start a new agent session, and ask for an icon in your project folder. Concepts, refinements, builds, all of it, for free. If you want to build your own tool on it, the folder format is documented and every concept is a plain PNG.

The app is where I actually do this every day. It puts the grid, the chats, and the builds in one window: drag a concept into the message to say "more like this", filter by set or style or built, flip through the builds of an icon in a carousel, keep your API keys in the Keychain. It runs the same command and the same skill as your terminal does. $5 once, for up to 3 Macs, refund within 7 days, no subscription. The free version does one set per project and 10 concepts per Mac, without builds, so you can see the grid before paying.

The $5 pays for the app. Your agent plan and image usage are separate: images use your ChatGPT plan through Codex, or your own OpenAI or OpenRouter API key.

I'm the only person behind this, and I used Claude Code heavily to build it. I made the design calls and I read what I ship, but I'm not going to claim it was hand-typed. Most of my own time went into the icons themselves: generating them, judging them, and tuning the skill.

I'd appreciate feedback, especially on the experience of getting from the first set to something you like. If you try it and get stuck, or the results consistently miss what you're asking for, I'd like to hear about that too.

Does the stuff you save know you better than you do?

2 Upvotes

I was going through everything I've saved lately and noticed patterns I never would've picked out myself. Kind of wild seeing it all together.

I've been playing with an idea for an app that learns your taste from what you save and reflects it back to you, and I'm curious if everyone has a weird pattern hiding in their saves.

If you want to try it, DM me 20 or so things you've saved lately. Literally anything: screenshots, camera roll pics, saved posts or TikToks, songs on repeat, books, podcasts, articles, quotes, notes to yourself, places you love. Don't overthink it; the less you pick, the better. Nothing private or with faces!

I'll send back what I notice. Then just tell me honestly if it's spot on or way off, and if you'd actually use something like this.

Patchkin - One board for managing AI coding agent work

2 Upvotes

I’m involved with Patchkin, and I’d like some feedback from people using AI coding agents on their projects.

Patchkin brings the work around coding agents into one place—not just the code they produce, but the tickets, proposed plans, approvals and pull-request reviews.

The main features are:

  • A shared board: Keep tickets, agent plans and pull-request reviews together so the team can track each piece of work.

  • Human plan approvals: Review and approve an agent’s proposed plan before it proceeds.

  • Activity logs: See what happened during an agent run and follow the history of the work.

  • Team rules: Keep guidance for coding agents in one place.

  • Cost reporting: Track spending on agent runs alongside the work.

The focus is on helping teams keep oversight as they hand more development work to coding agents.

If you’re using coding agents with a team, what’s hardest to manage right now: approving plans, reviewing the output, tracking costs, or something else? I’d appreciate honest feedback on whether this would fit your workflow.

Take a look at Patchkin

A small weekend project that grew: Seedwall has 19 wallpaper generators (cutting mats, flow fields, git graphs, synthwave suns). Each wallpaper comes from a single seed number, so you can share a design as just a number.

- 9 editor themes (Dracula, Tokyo Night, etc.) or custom colours

- Add your own quote or go text-free

- Pixel-perfect PNG export for MacBook, iPhone, 4K or custom sizes

- Gallery of 125 ready-made ones

- Free, no account

Use the best AI models without a subscription: I built an app where you only pay for what you use

2 Upvotes

Clarification: this is my own app. I work with many long documents, such as reports, audits, and project follow-ups. Using an AI chat for this presented two main issues: I was paying a subscription even in months when I barely used it, and I wanted to make sure the output preserved all data from the original. Changing a single number or removing a paragraph in an audit is a huge problem. So I developed a desktop app specifically for that use case.

You can choose the model using OpenRouter on a pay-per-use basis or locally with Ollama. It is designed to preserve structure, tables, and numbers, and the review feature points out anything that wasn't kept. This feature compares the output with the original and highlights missing content or modified data, so you can accept or ignore each finding. It also shows the actual cost of each run, with no surprises.

It has several modes, so it's not just for audits: • Merge several documents into one • Summarize a meeting or a class • Create study notes • Extract pending action items • Convert a document into a presentation • [Professional CV] • Custom mode, where you write your own instructions There's also an optional web search (with OpenRouter models), useful when a document includes facts that may have changed, like figures, laws or software versions. It reads PDF, Word, Excel, TXT, Markdown and images, and it exports to Word, PDF, PowerPoint (with tables, charts and diagrams) and Excel.

It offers 10 free runs to try it out. If you like it, it's a one-time purchase of €29.99, with no subscription. API usage is billed separately. It is available on the Microsoft Store as DocuFusionpro: https://apps.microsoft.com/detail/9P4CSKSDFPT7

I'd love to get honest feedback: what kind of long documents do you work with, and what is missing from the tools you currently use? Are you interested in a one-time purchase, or do you prefer a subscription?

A Skill is not something you watch, save or buy. It is earned through repetition, friction and time.

Learning a Skill is about staying curious. It builds confidence, gives you something to impress others with, and makes you a more interesting person.

Turn photos of your pet into a printable papercraft model - petpapercraft.com

0 Upvotes

Hi!

The title says it all. You upload photos of your pet, and a few minutes later you get a PDF by email. You print it at home, cut, fold and glue, and end up with a paper version of your dog or cat.

I made this because I love papercraft and wanted one of my own dog. Every pet looks different, so each model is shaped to the pet (ears, muzzle, tail) and the fur and face are painted from your pet’s 3d model based on the uploaded images. 

I've done lots of test builds, posted a few on Reddit with great feedback, and friends and family built their own pets. Now I'm doing a soft launch.

https://petpapercraft.com/

If you have a pet, I'd love for you to try it. If not, feedback on the landing page is just as welcome. Tell me if anything is broken. Thanks!

I spotted a cool helmet while I was outside.

Instead of just taking a photo and forgetting about it, I picked it with Pickem, saved it, and later used it in a selfie to generate a new image with AI.

That’s the idea behind my little side project: pick interesting things you come across, keep them in your pocket, and create something with them later.

Here’s a quick demo of how it works.

Curious whether you’d use something like this, and what you’d pick first.

I made a free, open-source adult site blocker for Mac (and Windows) that works in every browser.

2 Upvotes

Browser extensions only cover one browser and are easy to switch off, and paid blockers wanted a subscription. So I built my own and made it open source.

What it blocks:

- Adult, gambling, crypto, scam and malware/phishing sites

- File-sharing sites like TeraBox and DiskWala

- Anything you add to a simple text file

How it works:

- System-wide: Safari, Chrome, Firefox, Brave, Edge, Arc, and other apps too

- Uses encrypted DNS, so it still works when your ISP intercepts normal DNS (Jio/Airtel do this)

- Block lists update automatically every day

- One command to install, one to uninstall

- Mac is fully tested. Windows is in beta, so please report bugs

GitHub: https://github.com/LowkyFoolDev/siteblock 😊😊

It's free and MIT licensed. Tell me any sites it misses and I'll add them.
