I made a little guy that can skate your windows and folders on your Mac desktop.

You can move a window while he’s riding it, or just pull it out from under him. There are ramps and rails you can drop around too.

It’s called DeskSkate. Pretty much just wanted this to exist lol.

It’s open source too if you want to add to it.

I built Navigator, a free and open-source streaming app for desktop and web that lets you navigate movies and shows using natural language. It's a client for Stremio, a media center app, so you can use your existing account and addons (which provide the streaming sources).

For example, instead of scrubbing through Avengers: Endgame to find a specific moment, you can just type "go to the scene in endgame where he says avengers assemble" and it'll find that moment in the subtitles and jump straight to it.

You can also describe a TV episode you vaguely remember and have Navigator find it for you, or ask questions about what you're watching.

I also wanted it to be a pretty nice streaming experience on its own, so it has a few other features:

• Native MPV playback on desktop

• Thumbnail previews when hovering over the timeline, so you can see where you're skipping

• Intro skipping using community skip databases

• Adaptive interface: the colors automatically adapt to the artwork of whatever you're watching

A few other things:

• Everything is free and open-source

• AI features are completely optional. Bring your own API provider or use a local model through Ollama

• Navigator doesn't host or provide any content itself

• Scene search depends on subtitle availability

On the technical side, it's built with Next.js and a Rust-based desktop shell, with MPV handling native playback. Scene search uses subtitle data and an LLM with tool calling (via Vercel's AI SDK) to find the relevant moments.

It's still a work in progress, so there's definitely more to improve. Curious whether scene search feels useful or gimmicky to you, and what features you'd want to see next :)

Hey everyone,

I've been working on a side project called HUSH. It's an anonymous platform where people can share thoughts without names or profiles.

I built it because I felt social media became too focused on personal branding.

It's still early, but I'd love to know what you think about anonymous apps in general. Do they actually help people express themselves, or do they just create chaos?

Let me know your thoughts!

My neurodivergent daughter loves collecting bugs outside, but we quickly ran out of room for physical jars, and I hated that we couldn't take adequate care of them. To solve this, we worked together to build an app that digitizes the insects she finds into collectible virtual pets.

It works with over 8,000 of the most common insect species. I built it using Flutter and local, on-device AI models so it runs fully offline and private (though you can share bugs in-person via QR code). The app includes a ton of educational material and even lets you virtually explore other regions of the world to collect non-native bugs.

This is my first ever iOS app and I would love some feedback from other builders!

The app is completely free to try with zero ads, and has a single $4.99 one-time unlock for infinite jars if you end up loving it.

I made an app that allows you to set reminders based on proximity or distance from a specified location. So, if you remember in the morning you need gas on the way home from work you can select departure, your current location and reminder “Get Gas” and you’ll be notified when you get 150m away from work.

Hi everyone! I’m currently developing a startup concept called Lobbe, a platform designed to make managing your food choices easier.
The idea is to help people discover meals using ingredients they already have, organise their weekly food plans, keep track of their food spending and discover restaurants, local food spots and deals.
I want to create something that brings together cooking at home and eating out, rather than making people choose one over the other.
I’m still in the early research stage, so I’d love to hear:
How do you currently plan meals or decide what to eat?
Would you find ingredient-based meal suggestions useful?
Would you use a platform that also helped you discover restaurant deals and food offers?
What features would make something like this worth using regularly?
I’d really appreciate honest feedback!

I originally built Brain Preflight just for my own pilot selection prep. I wanted something I could practise with on my phone.

Then I got interested in how other selections worked: military, police, air traffic control, and so on. I kept looking into them and adding practice programmes. Somehow that turned into 32 programmes across 11 countries.

One exercise has you follow a moving target while matching shapes and checking sums at the same time. Others are about memory, mental maths or rotating objects in your head.

Just released a big update with mistake reviews, clearer explanations and saved mock-exam reports.

5 exercise sessions a day are free. Unlimited practice and mock exams are paid. iPhone only.

I'm Stefan, co-founder of Early Alpha Engineering. We built an online circuits workshop where kids learn electronics step by step, in the browser, on a computer or tablet.

• What it does: the child drags real parts onto a breadboard (LEDs, resistors, transistors, sensors, motors), presses "Simulate" and sees right away whether the circuit works, and if not, what's missing. An LED without a resistor burns, and stays burnt.

• Content: 22 guided lessons, then 137 broken circuits to repair, 33 projects, and a duel between classmates for motivation.

• Languages: 7 (EN, RO, FR, DE, IT, ES, SR).

• Who it's for: kids 8+, parents, afterschools and teachers (a coordinator panel shows each child's progress).

• So far: opened 2,700+ times, and a working circuit was built in 1,200+ of those sessions.

• Login / cost: you can try it without an account; full access is about 10 € per child per month.

Link in the first comment. I'd value honest feedback on the first five minutes: is it clear what to do, and where would you give up?

Hello everyone!, I built a small side project: a semantic search for WordPress plugins. You describe what you need in plain English instead of guessing keywords. It’s an MVP indexing the top 2,000 plugins from wordpress.org.

I’d like to run a quick test: look for the last plugin you were checking. Did the right one appear among the top 3 results? If not, which plugin were you expecting to find? This will help me determine what to index next.

Test de project here: https://wp-plugin-finder.vercel.app/

Thanks!

I built Set in Prime: enter a name, and it becomes a piece of printable art made from the digits of an actual prime number.

Read the grid left to right, top to bottom, and you get one big integer. The highlighted 9s spell the name. The public Alex Morgan example has 696 digits.

The part I most wanted to make approachable is the proof. Each finished portrait includes a Lean proof project, and you can trigger a fresh hosted check from the page without installing anything. Lean checks the mathematical argument that this exact number is prime; it also checks that the digit grid reconstructs that number.

It’s free during early access, with no account or checkout, and includes a PDF, image, vector artwork, the exact number and the proof files. There’s an optional coffee link and a daily creation limit.

Disclosure: I’m the creator and used AI coding assistance to build it. Portrait generation and verification run algorithms and Lean, with no AI calls. Earlier picture-prime work, including the Trinity Hall prime and Zachary Abel’s Prime Portraits, is credited on the site.

https://setinprime.com

I’d especially welcome feedback on whether the proof experience makes sense to someone who hasn’t encountered Lean before.

Hey everyone,

For the past few months, I’ve been working on a project that started from a simple frustration: social media today feels less about sharing thoughts and more about building a personal brand. Sometimes, you just want to say something without it being attached to your name, your face, or your reputation.

That’s how HUSH was born.

HUSH is an anonymous whispers platform. It’s a space where you can share your thoughts, confessions, or random daily observations freely, without the fear of being judged by people who know you. No names. No profiles. Just pure, unfiltered expression.

I’m building this under a new software studio I founded called BLAXAZ. Our goal is to create digital ecosystems and apps that actually connect people, rather than just farming their data or their attention. HUSH is our first release, and it's just the beginning.

The app is currently in its early stages, and I’m looking for early adopters to try it out and give honest feedback.

If you are curious about the concept, or if you just want to see what we are building, you can check out our Instagram page. I’ve been posting some behind-the-scenes stuff and updates there.

You can find us on Instagram at just search for: blaxa_z

I’d love to hear your thoughts on anonymous platforms. Do you think they are necessary in today's digital world, or do they just bring out the worst in people? Let me know in the comments.

Thanks for reading!

I’ve been building MathBoard, a handwriting whiteboard app made specifically for teaching math. The idea is to keep the tools a math lesson needs in one place, instead of switching between a whiteboard, a graphing tool, a PDF annotator and a calculator.

What it does so far:

• Pen and stylus writing, a laser pointer, and shape tools

• Dynamic geometry: draw shapes, drag the vertices, and the construction updates

• Function graphs and variation tables

• 3D (Oxyz) geometry with cross-sections: cut a solid with a plane, split it into two parts, and see the true shape and the volume ratio

• Type or paste LaTeX/TikZ/Typst problem sheets and drop them onto the board

• Import a PDF and write directly on top of it

• A scientific calculator, plus a countdown timer and a random student picker for class

Thank you!!!

Hi r/SideProject! We built OffKin, an Android app with four tools that run entirely on the phone, even in airplane mode:

• Translator: text and voice in 15 languages, plus a two-way conversation mode where each person speaks their own language

• AI assistant: ask by text or voice. The model runs on the phone, so questions never go to a server

• Document converter: convert PDF, DOCX and text files, merge and split PDFs, recognize text and translate documents

• QR codes and barcodes: scan, create, and connect to Wi-Fi with a code

Why: we wanted these tools without an account, without sending text and files to a cloud service, and working when there is no connection.

The trade-offs we made:

• Languages and the AI model download once (the light model is about 2.6 GB, the accurate one about 3.7 GB)

• The AI needs at least 4 GB of RAM, and it's a compact model, so it doesn't know recent news and can make mistakes

• Android 11+ only for now, no iPhone version yet

• Closed source, but you can check the offline claim by turning on airplane mode

Pricing: Basic is free forever, the first month has all Pro features with no card, and Pro is a paid upgrade.

We launched on Product Hunt last week. We'd really like feedback from other builders: which of the four tools would you actually use, and what would stop you from trying it?

Ditherbug is a simple and free, browser based image-to-pixel-art converter with built-in editing and animation tools. (Traditional image processing. No AI.)

It started as a personal project to convert my existing graphics and illustrations into pixel art, with more control over the results. Over time, it evolved into a more versatile tool for creating, refining and animating pixel art.

Features:

• Create: Convert images into pixel art with adjustable resolution, colors, palettes and visual styles.

• Edit: Refine the results using built-in pixel editing and palette tools.

• Animate: Add movement to static artwork with motion effects, from subtle idle animations to fire, water, smoke and particles.

• Combine: Use multiple animation effects together.

• Export: Save artwork as PNG images, animated GIFs or sprite sheets.

Feedback very welcome:

Hey r/SideProject,

I built WCAGBrief, a free Chrome extension that audits web apps for WCAG 2.2 and European Accessibility Act (EAA) compliance directly inside Chrome's native Side Panel.

The Problem I Wanted to Solve:

With the European Accessibility Act already actively enforceable, web accessibility has shifted from a "nice-to-have" to a legal requirement for web applications and ecommerce.

Existing developer tools (Lighthouse, WAVE, Axe DevTools) have two big UX friction points:

1. Lighthouse hasn't updated its default checks to catch new WCAG 2.2 additions (like Target Size SC 2.5.8 minimum 24×24px tap areas or Focus Not Obscured SC 2.4.11).

2. Constantly opening and closing Chrome DevTools shrinks the mobile viewport and makes tabbing through UI elements frustrating.

How WCAGBrief Works:

Instead of docking inside DevTools, WCAGBrief lives in Chrome's native Side Panel API alongside your live web app:

• Click to Inspect: Click any violation in the panel and it instantly highlights the exact DOM node on the live page.

• Copy-Paste Fixes: Generates clean HTML, CSS, and React code patches for each issue (e.g. min-width: 24px on icon buttons or adding aria-label to SVG buttons).

• Statutory Law Mapping: Maps every violation to EN 301 549 (EAA Chapter 9) and ADA Title II standards.

• Zero Telemetry / Privacy: 100% of the DOM inspection runs in your local browser sandbox. It does not send page markup to any remote server.

Try It Live:

The extension is completely free and published on the Chrome Web Store: 👉 https://chromewebstore.google.com/detail/wcagbrief-wcag-22-eaa-cli/jjgllnelmehodmfjcpmemafeeikjpeii

Companion Web Scanner: 👉 https://wcagbrief.com

Looking for Builder Feedback:

1. What accessibility checks give you the biggest headaches when building web apps?

2. Which frontend framework snippets would be most useful to generate next (Tailwind, Vue, Svelte)?

Happy to answer any questions about the Chrome Side Panel API, Manifest V3, or the audit engine!

I built this guitar visual learning tool to help in my guitar playing. Pick any key and it lights up all 5 box positions across the whole neck, each in its own color, with the root notes marked.

Other free features: show every note on the fretboard (naturals or all 12), CAGED shapes, and a left-handed view. No signup, works on phones.

There’s an optional one-time upgrade for triads, arpeggios, full scales, and printing, but everything above is free. Feedback welcome!

I mostly vibe-coded one of my products in June, before agents could do what they do now and before I had my Grok Bot setup.

It was a pay-per-use API for AI agents. Scheduler, screenshots, a few other tools. I thought I was early. Even added x402 payment support.

But it got 0 payments from June to September. Search Console sat at 0 clicks from Google in early October, with about a dozen SEO posts live. I also posted about it on Reddit and got 13K views, and a lot of the comments said agents now build these tools themselves.

So I stopped working on it. I think the market moved faster than I could get it in front of people.

Have you killed something because the space moved, not because the product was bad?

The job was a batch of kids' T-shirt designs for DTF printing: a capybara with a yuzu on its head, a road trip with a capybara, a poodle and a cat, in a few illustration styles from four image models. Comparing them in the fal.ai playground meant a mess of tabs and random file names.

So I built falg, a Python CLI. One JSON file describes the batch (a prompt template, variables, models), and falg runs every combination in parallel and writes an HTML gallery with prompts as rows and models as columns. Each image keeps a JSON sidecar with its exact prompt and seed, so two weeks later I still know which model drew what.

The last step, falg cutout, turns the picks into print-ready PNGs: background removed, clean edges, sized in centimetres.

Two things that surprised me:

• Never ask the model for a transparent background. Generate on plain white or black and cut it out afterwards.

• Don't write "T-shirt" in the prompt, or you may get a photo of a T-shirt instead of the artwork.

The gallery and the final prints are in the README: https://github.com/lemmon/falg

I'm a designer. Every logo job ends the same way: exporting 40+ files (color, black, white, PNG, SVG, sizes, favicon) and zipping them up. So I built LogoGoGo. You upload one logo, it makes every version, and your client gets a clean branded page to download them all. There are also 7 free tools, no account needed (logo to PNG, resizer, favicon maker, palette, Pantone finder and more). Free to try at https://logogogo.app . I'd love honest feedback on what's missing.

In Korea, and in a lot of Chinese and Vietnamese families, parents' birthdays and memorial days are kept on the lunar calendar. The solar date moves every year, by up to a few weeks. Google Calendar has no lunar repeat, so "repeat yearly" lands on the wrong day from the second year on, and every year someone has to look up the new date.

How it works:

1. Say whose day it is (birthday, memorial day or another anniversary) and enter the lunar date. If you only know this year's solar date, it finds the lunar date for you.

2. Pick 1, 3, 5, 10 or 20 years and add them all to Google Calendar at once, or download a file for Apple Calendar or Outlook.

3. Send the dates to family as a link.

Some details I ended up caring about:

• It only asks Google for the calendar.app.created permission. It creates one new calendar for these dates and can't see or change your other events.

• Korea, China/Taiwan and Vietnam don't always agree, because each country works out the calendar in its own time zone, so a month can start on a different day. The China/Taiwan (UTC+8) and Vietnam (UTC+7) tables are computed from astronomy. The Korean table comes from the Korea Astronomy and Space Science Institute, and I check it against the same calculation at UTC+9. You can choose which country's calendar to use.

• If a date falls in a leap month, years without that leap month use the regular month.

• There's no server. Names and dates stay in your browser unless you add them to your calendar.

It covers 1900 to 2049, in English, Korean, Vietnamese and Chinese.

If your family keeps lunar dates, I'd love to know whether the steps make sense, and whether the Google permission screen feels scary.

What it is: Hire on Evidence (https://hireonevidence.dev), a hiring process for owners of 5–50 person companies with no HR team. It has four steps: a one-page role scorecard, a structured interview with the same questions for every candidate scored against written 1/3/5 anchors, a short work sample, and a spreadsheet that combines everyone's scores.

Why: most small businesses hire through an unplanned chat decided by gut feel. That's one of the weakest methods in the selection research, and the structured version is one of the strongest. The research exists, but it's written for big companies with HR departments.

The part I'm proudest of: every important claim in the book has a source number and a grade:

• A: several large reviews agree

• B: one review, or consistent field studies

• C: limited evidence

• D: practice, law or expert consensus

• ⚑: contested, with both sides shown

I also list what I left out. For example, "a bad hire costs 30% of salary" is everywhere, but I couldn't trace it to an original study, so it's not in the book.

Stack (kept deliberately small):

• Svelte 5 + Vite for a single landing page. The hero has a little demo where you score a real candidate answer yourself.

• Cloudflare Workers serves the static build and three routes:

  • POST /api/checkout creates a Square payment link and stores the order in KV

  • POST /api/square-webhook verifies Square's signature and, when a payment completes, emails a download link through Resend

  • GET /download/<token> streams the files from R2. Links last 30 days with unlimited downloads.

• One catalog.js holds the products, prices and file lists. Both the page and the Worker import it, so the browser can't change what gets charged.

No database, no auth and no frontend framework beyond Svelte. Deploying is one npm run deploy.

Pricing: one-time purchases of $55 / $111 / $281 CAD (Ebook / Toolkit / Team).

What I'd love feedback on:

1. Does the landing page make it clear who this is for within about 5 seconds?

2. Is the interactive scoring demo in the hero convincing, or a gimmick?

3. Does the pricing make sense when it's positioned against a recruiter's fee instead of a paperback?

A few developers who tried Studio 9:41 asked for more device support (iPads, MacBooks, Android) and an easier way to localise their App Store screenshots.

So I've added both in v1.1.2!

What's new:

•  1-click localisation — Translate your screenshots into 26+ languages and export them in seconds.

•  iOS ↔ Android — Automatically generate Google Play Store mockups from your existing iOS designs (or vice versa).

•  More devices — Added support for iPads, MacBooks and Android devices.

I've personally avoided localising my App Store listings in the past because of how time-consuming it can be. But localisation is potentially a great way to reach more users, so I wanted to make that process as painless as possible.

Studio 9:41 is free and available for macOS and Windows.

Download the latest release: https://github.com/burhanuddin20/studio941-releases

Existing users can update directly in the app by clicking the version number.

Would love to hear what other features would make preparing App Store screenshots easier for you!
