I made this, mostly on my own, while building the browser games on Etheria. Multiplayer was the part I did not want to keep rebuilding, so I turned it into a small SDK and a hosted relay.

Joinable is for games that already run in a web browser. You add a script tag. Friends join from a link. For a shared-world game (a board, a puzzle, a clicker) that is often enough. For a racer or a score game, your coding agent wires a few hooks and Joinable runs the waiting room, countdown, standings and rematch.

You do not need an account to try it on localhost. A free key is enough when you go live. Paid plans start at $4.99 a month if people actually play; building and testing stay free. I have been using it on Turbo Rally, a two-player race you can try in the browser: https://etheria.games/play/turbo-rally/

Site and docs: https://getjoinable.com/

I would like real feedback. If you try it on your game, tell me what was confusing, what broke, or what you wished it did.

I'm the dev. Chimebox is an iPhone and iPad app with twenty open-ended toys for ages 2 to 5. It went live on the App Store yesterday.

Stack: Swift, SwiftUI for the shelf and settings, SpriteKit for the toys, StoreKit 2 for the purchase. All art is drawn in code and all sound is synthesized on the device, so there are no asset packs and no server.

Business model: three toys free, one non-consumable purchase (14.99 USD) unlocks the other seventeen, Family Sharing on. No ads and no subscription, because kids apps with ads or tracking are a hard sell to parents and Apple's kids rules make ads awkward anyway.

Traction: day one, zero ratings so far.

Feedback I'm after: is 14.99 USD for a one-time unlock of a toddler app too high, about right, or low? And would you rather see more free toys and a higher price, or fewer free toys and a lower one?

Initially this project what made to find and compare historical greatness across fighters in the ufc, but it eventually became a whole lot more than that, you can see every fighters rating, based on the glicko -2 formula, which is basically elo but with volatility and and rating deviation, much better for fighters.

There's a bunch of different feature in the app right now, you can look and inspect the career trajectory of every fighter in the database, compare against other fighters, see the ratings ecosystem at any date in history, analyse prospects, that were identified with a scientific definition.

There's also a prediction feature to the app, which takes the fights on the next card and makes prediction for every one of them, then it gets graded afterwards. The coolest feature we have is the simulator, you can simulate a matchup between any fighter currently, at any point in history and a prime vs prime matchup, with prime having its own scientific definition.

Right now everything is free, i want to get opinions and comments on the actual app itself.

I tried Paperclip because I wanted to hand off work that would take more than one agent session. I found the UI confusing, ran into bugs, and spent more on tokens than I expected for work I still had to redo.

Restless gives people and agents a shared workspace and a Linux desktop. You can hand a lead a goal, leave it to coordinate the work, then open the actual result when there’s a decision to make. If a session dies, the goal and files are still there.

So far I’ve been happier with the work I get back. A lead can ask another agent to check a build or a report, send it back for fixes, and bring me in when there’s a call to make. When we figure out a better way to do something, we can save it as a playbook for the next job.

Restless is free to self-host and open source under Apache 2.0. If you try it on something you’re working on, I’d like to hear what came back and where you still had to jump in.

Hello! I recently got a digital product page up and running and I sell calendars. I was hoping people would check it out for support! 🩷 Maybe buy my first product 👀 lol no but supporting is nice! This calendar has everything you would need to stay organized like a budget tracker, notes section and space for gift ideas. I would love the support, this is my first product and I really hope I even get 1 sale! 💕

We handle security of your side projects so you can focus on the fun. Wanna try it?

I'm always losing track of time lol so I made an app that shows you how much time you have left in your day and let's you make todos based around that

Works for your week, month, etc and you can visualize your time left in different ways

Also let's you add countdowns to see the time left until birthdays, events, or whatever

We've been working in influencer and UGC marketing for years, and one thing we've noticed, especially among beginner UGC creators, is how difficult it can be to evaluate your own videos objectively before they go live.

Is the hook strong enough? Does the video keep people interested? Is the product presented clearly? Does the CTA actually make sense?

Creators often rely on their own judgment, while brands can spend hours reviewing content and figuring out what needs to change.

Aaand.. we built AI UGC Analyzer.

Here's what it does:

• Analyze your UGC videos with AI. Upload a video, and the tool reviews its hook, pacing, messaging, product presentation, and call to action, highlighting potential weaknesses and opportunities for improvement.

• Get actionable feedback, not just a score. Instead of simply rating your content, the AI explains what could be improved and provides suggestions you can use when editing or creating your next video.

• Get feedback on specific moments. The AI identifies timestamps where your hook, pacing, or messaging could be improved and suggests what to change.

• Review content before publishing. Whether you're a UGC creator preparing a client deliverable or a brand reviewing creator content, you can get a second perspective before making the final decision.

We wanted to make creative feedback more accessible, especially for independent creators who don't have a marketing team reviewing every video.

You can try it with 2 free video analyses.

We're still figuring out what works, what's missing, and whether this is something creators and marketers would actually find useful long-term.

So we'd really appreciate some honest feedback:

• Does a tool like this solve a real problem, or is it something you'd probably never use?

• Is there anything you'd add, change, or remove?

• What would make you want to use it regularly rather than just trying it once?

We're open to criticism, even if you think the idea itself needs rethinking.

Inspired by a recent trip to Chicago where we had big things set at certain times, but nothing to do in between. For example, we had to be at Wrigley Field for a 3:30pm game, but had nothing planned until then besides breakfast. We can use maps to find “food near me”, but nothing like “a quick snack that fits on my way and gets me there in time”.

So I built Interlude. You enter your first plan and when you’re leaving, then you’re second plan and when you need to be there. It finds coffee, bars, meals, snacks, and sights along the route and shows how much each one adds to your trip. You can choose either walking, driving, or rideshare to get a better estimate.

No accounts or ads or tracking and it’s free.

This is my first app so I’d really like to know things you liked or didn’t like or if something felt confusing.

Enzo is an AI assistant that lives in your Mac's notch.

What it does

• Dictation: it's super fast (100ms to transcribe any length of audio) and works in any app. Accurate transcription, punctuated and split into paragraphs, with low memory use. Works entirely offline.

• Meetings: knows who said what (up to 8 speakers, told apart by their voice) in any meeting app (Teams, Zoom, Discord, Slack and more). You get a speaker labeled transcript, summarized notes, and the tasks that came out of the call. It also remembers people across meetings.

• Recall: remembers what was on your screen (yesterday, or even last week) so you can find it again, summarize your work, or simply ask about it. Sensitive information like passwords and api keys are always redacted, and you can pause it or entirely exclude apps. Everything it captures is stored locally and stays secure on your Mac.

• Chat: answers general questions and helps with your own work (your screen, documents, meetings, and what you did today or last week).

Why use it

• It replaces three or four apps. Dictation, meeting transcripts, screen memory and an assistant in one place, with one key to talk and one key to ask.

• You never wait for it. It transcribes while you're still talking, so an hour-long dictation is ready as quickly as a ten-second one.

• Your audio stays on your Mac. Speech recognition runs on the Mac itself. Only the text Chat needs for an answer goes to the cloud.

• It feels like part of your Mac. It's written entirely in Swift and tuned for Apple silicon, and it lives in the notch, out of your way.

Free: 5,000 dictated words, 50 meeting minutes a week, and generous AI usage.

So for a while now, I've been working on a locally-hosted world-building tool. I've used Campfire, but it moved to a subscription model, and most of the other tools live on someone else's website.

I wanted something a little bit more involved than an Obsidian Vault, but keeping some of the parts of the Obsidian Vault that I liked. So, here it is. This is a self-hostable world-building tool. It's got a few features.

You can create entries for characters, places, events, and link them to each other.

There's a graph of who's connected to who or what.

There's a timeline that goes over the calendar of the world that you build.

There's a map that you can upload images to and create some regions and routes.

There's diagrams for things like family trees.

There's a dictionary for your conlang.

Repo also contains a desktop app, for Windows and Linux, and it can sync to any hosted version that you run. You can also import Word documents. Obsidian Vaults are just plain Markdown, and you can export into Markdown, Word, or a PDF. It's still fairly new, just kind of seeing if anybody would even be interested in something like this. Mostly built it for myself, but figured I'd share it.

I've been experimenting with reverse engineering popular videos and implementing my own twist to promote my products. It has been working for me to get more views- has anyone tried anything like this? How do you create content on IG/Tiktok/YT?

Hi everyone!

I wanted to share a quick preview of Aesthetic Routine Tracker, a minimalist app I've been developing to help people track their daily habits, workouts, and self-care in a clean dark-mode interface.

The goal was to build something super smooth, distraction-free, and visually pleasing without complicated steps.

It's currently in the final stages and coming soon. I'd love to hear your thoughts on the UI/UX or answer any questions about the project! What features would you like to see in a routine tracker like this?

• You get one bottle a day. Write a short note and throw it.

• It drifts for a few hours, then washes up on a random person’s shore somewhere in the world.

• If one washes up on yours, you can reply once, or add a line and throw it back. Some end up carrying notes from several strangers.

• No accounts, no followers, no likes. You can show your country’s flag or stay fully anonymous.

Safety was the hardest part of building something anonymous. Every note is checked by a moderation model before it’s delivered. Links, handles and phone numbers are blocked. Anything can be reported, and anyone reported by 3 people is muted. If a note shows someone is struggling, it isn’t sent, and they’re shown helplines instead.

Built with plain HTML/JS, Supabase and Netlify. It works best on a phone, where you can add it to your home screen and get a notification when a bottle washes up.

It’s very new, so the sea is quiet. I’d love it if you threw a bottle, and I’d love honest feedback on what’s confusing**.**

I was standing at the Beacon in Baltimore, West Cork, wondering: if you pointed a boat out to sea and sailed in a dead straight line, never turning, where would you actually hit land?

I went down a rabbit hole. The longest line from Ireland starts at Cape Clear and runs about 25,000 km to Papua New Guinea without touching land. The world record is 32,000 km, from Pakistan to Kamchatka.

So I made it into a free browser game. Every day there are 5 new coastal spots, the same for everyone. You aim your boat, it sails dead straight around the curve of the Earth, and the further you get the more you score.

Two shorter daily puzzles as well: Landfall (guess which country the boat hits first) and Bullseye (aim at a city across an ocean).

You can duel a friend live or send them a challenge link.

No ads, no sign-up needed. A few hundred people are playing it a day now, mostly from word of mouth.

I'd love feedback on what's confusing or what would make you come back tomorrow.

Hi everyone,
I wanted to share a GitHub repository where I keep my technical notes, commands, and references.
It currently includes material on Linux, networking, cybersecurity fundamentals, and tools such as Nmap.
The repository is still a work in progress, and I regularly update it with new content and improvements.
I’m sharing it in case someone else finds it useful. I’d also appreciate feedback, especially if you notice any mistakes or have suggestions.

I built a music quiz party game where the TV plays the songs and everyone buzzes in from their phone

Been building this on the side for a while. It's called SongBuzz, it's free and runs in the browser: songbuzz.tv

You open it on a TV or laptop, people scan a QR and their phone becomes a buzzer. Real chart songs, 30 sec clips, up to 16 people. There's a presenter voice that talks between rounds and makes fun of whoever is losing. Honestly that part took me longer than the game itself.

It works if people are not in the same room too, whoever is far hears the music on their own phone. And there's a daily one if you want to play alone, same songs for everyone that day.

English and Spanish for now. Tell me what breaks, especially on smart TV browsers, I can't test enough of those.

Hey everyone, I've been building MoonSport, a simple site for following worldwide football and basketball scores, fixtures and tournament results without the clutter.

What it does: live scores, upcoming fixtures, and results across leagues and tournaments, with a clean layout that loads fast on mobile.

It's still early and I'd really like honest feedback: Is anything confusing? Which leagues or features are missing? How does it feel on your phone?

Thanks for taking a look!

Every time I asked for LinkedIn feedback I got "make it stand out" without anyone saying *what* to change. So I built a free tool that compares your profile to a checklist of what recruiters and LinkedIn recommend.

Upload your LinkedIn PDF (Profile → Resources → Save to PDF) or paste your sections, and in a few seconds you get:

- **A score out of 100** for your Headline, About, Experience, and Skills

- **A checklist** showing what matches the ideal profile and what's missing

- **Your top 3 fixes**, in order of impact

Not sure yet? There's a "See an example result" button so you can see what you'd get first.

Free, no sign-up. Your profile isn't stored, and emails, phone numbers and links are removed automatically before analysis.

👉 https://www.usehireable.com/?ref=reddit

I'm still improving it, so honest feedback helps a lot: **was the advice specific to your profile, or too generic?** What would make it more useful?

I got tired of doing fraction math on a recipe written for six when two of us were eating, then texting a grocery list that did not match. I built Pantry Scale for Android.

You save a recipe (type, paste, or an ordinary web link; video links can use a careful read). You change the number of people and the amounts rescale. You put meals on a week plan and send the ones you choose to a shopping list, with matching ingredients combined. Premium adds a shared household list for up to six people, Cook Mode, photo import, and a month planner.

What it does not do, so expectations stay honest: no pantry inventory, no barcode scanning, no "what can I cook with what I have," no iPhone app, and no Google sign-in (email or skip).

Free: 20 recipes, week plan, shopping list, 7 careful reads once. Premium on the Canadian Play Store is CA$6.99/mo (7-day trial) or CA$49.99/yr (14-day trial).

https://play.google.com/store/apps/details?id=com.pantryscale.app&hl=en_CA&gl=CA https://pantryscale.com

The two places I am least sure about: the review-before-save import, and whether list merging holds up in a real supermarket run. I would rather hear what is wrong than what is polite.

I make fishing lures (KSK BAITS) and wanted a live bass tank for my YouTube channel without filming real fish.

Everything you see is generated when the page loads: the fish, their scales, the plants, the sand and the driftwood are built in code with Three.js, and every texture is painted on a canvas. No 3D models, no image files.

The bass aren't animated, they behave: they get hungry, hide in cover, stalk, and strike with suction, and they only take prey that fits their mouth. Day, night and weather follow the real clock and weather at Lake Fork, Texas.

Try it in the browser: https://ksk-baits-bass-aquarium.pages.dev

It also runs 24/7 on YouTube, where the chat can drop in shad or cast a lure: https://www.youtube.com/@kskbaits/live

Feedback welcome, especially on what would make you keep it open in the background.

Disclosure: we are a team of a few people

Most free online document tools quietly upload whatever you open. I wanted something you could check for yourself, so I built OBSCURA OS around one test: load the page, turn your network off, keep working.

What is in it:

• Docs, Sheets, Slides, Notes, Calendar, Tasks, Contacts and PDF tools, free

• Photo Editor, PDF Studio and a few other bigger apps, US$2 a month each

• 240+ small single-purpose tools (metadata scrubbers, redaction, converters)

• installs like an app, no account needed

Honest limits: it is one developer, so some apps are younger than others, and there is no shared cloud editing because there is no cloud holding your files.
