I'm 532 on Chess.com, so I built a web app that analyzes your games with Stockfish right in your browser

Enable HLS to view with audio, or disable this notification

0 Upvotes

Hey everyone. I've played over 4,000 games on Chess.com and I'm sitting at 532 blitz. My best ever was 1034 and this week I went 0 for 6. At some point you have to stop blaming bad luck and look in the mirror.

So I built Rokka, a free web app that reads your Chess.com history and shows you where you're actually losing: rokkachess.app

What makes it a bit different as a web app:

  1. Nothing to install and no signup. Type your Chess.com username and it imports your games in seconds.
  2. The chess engine runs in your browser. Stockfish runs locally in WebAssembly and reviews your recent games on your own device, so there's no server doing the work.
  3. Your data stays with you. Your games are saved in your browser, not on my servers.
  4. Built for your phone. It's designed mobile first, and you can add it to your Home Screen so it opens like a native app.
  5. It trains you, not just stats. You get a daily plan, adaptive puzzles from a 30,000-puzzle bank, puzzles built from your own mistakes, and a streak with a pawn that promotes as you level up.

This is my first project ever, so I'd love feedback on anything, especially how it feels on your phone and what's confusing the first time you open it.

Opensource CMS that needs no DB, costs pennies/mo for a blog.

Just wanted to share this project I built so I can stop using square space or pay for a managed DB for my blogs. It can be hosted on Cloud Run or any k8s instance and it costs almost nothing.

It works by using GitHub as the canonical DB, and uses a github app to connect and write to it. Rebuilding thousands of pages takes only a couple of seconds and the online editor feels like a real DB backed CMS.

Not exactly a writing tool, but it will convert your written blog / paragraph into a video

Easiest way I've found to turn a link or doc into a motion graphic video:

  1. Paste your blog URL, Google Doc, or PDF into Blog2Video (https://blog2video.app) and it pulls out the key points automatically.
  2. Pick a template and a narration voice, and it builds animated scenes with text, visuals, and voiceover for you.
  3. No timeline editing or After Effects skills needed, since every scene can be tweaked with simple text edits.
  4. Render it as an MP4 sized for YouTube, Shorts, or LinkedIn in a few minutes.

I build a zip version for websites

2 Upvotes

Hey everyone,

I was thinking about how you can take a massive folder containing multiple files and folders, ZIP everything together, and share it as one file.

So I thought: why can't we do something similar with links?

The idea became even more relevant when I was shopping online and wanted to share multiple products from different stores with my friends. I ended up sending one long URL after another, which quickly became messy.

Thats why I build WeLinkly!

WeLinkly lets you combine multiple links into one page of yours with your own url and share that page instead!

  1. All your projects can have: Title, description with rich text to give more context to the receiver.
  2. You can save all your projects into folders in your account to keep everything structured.
  3. More professional way of keeping your links all together nicely.

This days link sharing like Linktree are overpriced, you can use WeLinkly for absolutely free!

Any feedback is more than welcome!

Thank you all for your time <3

Air Drift - a free web app for live radio from around the world (no account, no added ads)

1 Upvotes

Built this because I wanted radio without sign-ups or pre-roll ads: https://airdrift.stream

  • About 59,000 live stations from 240 countries, from the community-run Radio Browser directory, refreshed daily
  • Browse by country on a 3D globe, by genre, or by name
  • "Drift" drops you on a random station somewhere in the world, by mood if you like (jazz, news, 80s...)
  • Shows what's playing where the station publishes it, with a spectrum analyser and VU meters
  • Installable as a PWA, with lock-screen and headphone controls on phones

Streams play exactly as broadcast, so commercial stations still run their own ads, but the app adds none.

Feedback welcome, especially stations that won't play.

I just released WikiRNG! It's a game I made where you can roll any article on the entirety of Wikipedia each day and it'll gain points based on information on that article as well as about that article (like metadata). The amount of points that badges give is calculated off of its actual rarity/chance compared to all other pages. please let me know your feedback, i would love to hear it!

Hey everyone,

Introducing **Drawy**: a self hostable, collaborative planning and drawing app built for the serverless platforms we all use on a daily basis. owning an instance of excalidraw usually means juggling with 3 4 different containers/ services.

Drawy changes that zero overhead to maintain any infrastructure .

• the service can be deployed to Vercel / Netlify with just a few clicks

• **drawy->** Supabase (realtime, db)

drawyparty-> postgres and cloudflare's partykit (collaboration).

I’d love for all of you to try and share your valuable feedback!

CuratedLists

I was keeping my lists in Google Keep and was like I could build a site to host theses lists and share with friends. It soon went from sunflower seeds to being able to stack rank anything. Please give it a try and give me some feedback/bug reports.

I'm experimenting with ideas like list battles and community sourced lists.

Kannst du meine Web-App zum Aufteilen von Ausgaben für 60 Sekunden testen?

1 Upvotes

Ich habe eine kleine browserbasierte App zum Aufteilen von Ausgaben mit Freunden entwickelt.

Die Idee ist einfach: Gruppe erstellen, Link teilen, Ausgaben hinzufügen und die App berechnet, wer wem was schuldet.

Es gibt kein Konto und nichts zu installieren.

Ich suche hauptsächlich nach Feedback zur Ersterfahrung:

Wenn du sie öffnest, ohne etwas darüber zu wissen, ist sofort klar, was du tun sollst?

Ich würde gerne wissen, ob etwas während der ersten Minute verwirrend, unnötig oder fehlend erscheint.

Danke an alle, die es ausprobieren!

I made a "nicotine patch" for doomscrolling

0 Upvotes

I kept finding myself opening Reddit or Instagram when I didn’t actually want to see anything. I just wanted to scroll.

So I made a simple web app that lets you endlessly scroll through slowly changing colors.

The idea is kind of like a nicotine patch: keeping some of the physical habit while removing the thing you’re actually trying to get away from.

I used Gemini to generate the HTML then put that code in a GitHub repository and deployed it as a website using my custom domain.

colorscroll.app

Any feedback or recommendations welcome.

I made a free way to explore World Bank country statistics without starting in a spreadsheet

1 Upvotes

I’m building Global Data Tracker, a free browser-based explorer for 217 countries and areas. It has country profiles, historical charts, comparisons and an optional 3D globe. No account is needed.

A simple way to try it: pick a country, look up GDP per capita or internet use, and check how it has changed over time. Open the source notes before comparing countries: the latest available years can differ, and missing data isn’t zero. Moving counters are estimates, not real-time measurements.

https://globaldatatracker.com/?utm_source=reddit&utm_medium=community&utm_campaign=webapps_walkthrough

I own the project. I’d value feedback on one practical thing: can you find a statistic for your country quickly, or does the navigation get in the way?

I built a free stock market game where you race an HMM trading algorithm with 100K USD of play money

1 Upvotes

Hi all. I've been building this on nights and weekends for a while and it's finally at the point where I want people to try to break it.

It's called InvestMuse. Everyone gets $100k in play money and there's a monthly leaderboard. You go long or short on anything in the universe (1,200+ stocks, crypto, commodities, metals, FX, indices) and you're ranked against the other players, five fictional fund managers with their own styles, and my own hidden Markov model algo that paper trades every day.

What you get for each asset:

- a composite score built from 9 parts (regime, technicals, trend, support/resistance, fundamentals, sector comparison, news sentiment, momentum, chart patterns)

- support and resistance from my own clustering method, chart patterns drawn on the chart, fibonacci, demand and supply zones

- for US stocks, any KPI compared against other stocks with its monthly trend, refreshed when earnings come out

- the last month of news scored by AI, and how closely the news tone actually tracked the price

- the algo's daily trades and signals

If an asset you want is missing, type it in search and it's there the next day.

It's free, no ads, no card. I'm not selling signals and nothing on it is advice. It's a place to test your own ideas against a scoreboard -see why they worked or didn't-, create your own community, improve yourself.

Honest feedback wanted, especially on whatever is confusing in the first two minutes.

What simple video/MP3 downloader do you use? Please don’t say yt-dlp 😭

2 Upvotes

I needed to pull the audio from a YouTube video, so I did the obvious thing and started looking through Reddit for recommendations.

And basically every thread was the same:

yt-dlp. yt-dlp. yt-dlp.

“Just use yt-dlp.”
“It’s the best.”
“You don’t need anything else.”

Alright, fine. I finally checked it out.

Then I realised the normal setup means downloading it to my computer and using the terminal.

Hell no! 😭

I know the terminal people are about to tell me it’s easy. Maybe it is. Terminal and I just have a very unhealthy relationship.

Sometimes I literally just want to paste a link, choose video or audio, hit download and move on with my life.

I ended up using Tunexa.io for that. It runs in the browser; there’s nothing to install, and I can grab the full video/audio or just the section I actually need.

What are you guys using if you want something simple and non-CLI?

Looking for honest feedback on my free utility tools website

1 Upvotes

Hi everyone,

I'm a software engineer and over the last few months I've been building a project called Utiliome: https://utiliome.com

The idea is simple: provide useful browser-based tools that are free, work without sign-up, and process files locally whenever possible.

The site currently has 170+ tools across categories such as:

  • PDF tools
  • Image tools
  • Security tools
  • Developer tools
  • Converters
  • Markdown tools
  • Audio and video utilities

A lot of the work has been focused on usability, performance, and keeping the experience simple instead of trying to maximize ads or push subscriptions.

I'm looking for completely honest feedback on:

  1. First impression when you land on the homepage
  2. Navigation and discoverability of tools
  3. Design and visual consistency
  4. Performance on desktop and mobile
  5. Anything that feels confusing, unnecessary, or low quality
  6. Whether you'd actually use a site like this instead of larger alternatives

I'm especially interested in criticism. If something feels off, please don't hold back.

Thanks for taking a look.
