Here's a thread of every app I've built 100% with @cursor_ai using Claude.
These are all fun side projects I've worked on in my free time over the last few months.
1. simple binary analysis and hex editor fully client-side in browserNEW TOOL: HEX.DANCE It's a fully in-browser binary/file analysis tool with a hex editor. Features: - Hex editor and you can save the edited file - Mach-O symbols - ELF and PE basic metadata - Zip file contents - Fully client-side in-browser, so it is private and2. convert images into ascii art (and optionally save as images of the ascii art)NEW TOOL: ITOA (Image to ASCII) Convert your images to an ASCII canvas, monochrome or colored, and save them into a separate image. Works on mobile (but large size is more limited than on desktop).3. sort pixels by color to spite paulgINTRODUCING: pxl-srt It sorts pixels in an image by color (i implemented and deployed this 20min after seeing this tweet)4. list every single SSN (this needed some manual intervention as it was a fork of @itseieio and Claude initially refused to generate SSNs)I have leaked every single SSN into a public searchable list (in case you are looking for one). Your SSN is in here too, 100% guaranteed. Forgot your SSN? Need a new one? Use this tool!5. idle clicker game👾 NEW idle clicker GAME RELEASE 👾 Find out what happens when you unlock THE GLITCH! Works on any browser, try it and give me feedback6. credit card generatorMany websites ask us for credit card numbers, and I don't always feel like getting up to fetch my wallet. So I made a small app to generate a credit card number, details below.7. data transfer over soundNEW TOOL: Chirp Uses sound to transfer data between machines. Details and link below.8. Decimal to binary and hex with annotation to help explain how it works. Plus steps on how it was built.I made a React app to help me teach students how to read binary and hexadecimal. But more importantly, I documented the entire process below, step by step on how I made it with Cursor. So you can copy the steps and prompts to make your own apps.9. Game: guess the security tool from the ascii logoNEW GAME: Guess the security logo (in ASCII) 60 total logos to guess, it's harder than you expect. Let me know what you think of the tool selection! Link to play below.10. Largest password leak🚨I HAVE LEAKED EVERY SINGLE PASSWORD EVER (4 to 32 chars long)! That is 347 novemdecillion passwords, the largest password leak ever! ALL of your passwords are in here, GUARANTEED! This is a client-side app, so what you search for is all local, never sent anywhere.11. Coding LLMs write their own chessbots and fight each otherNEW Chess bot vs bot arena: I got different coding LLMs to implement their own javascript chessbots and fight each other. The results are a pile of hot garbage. This is the worst chess I've ever seen in my life (and i've watched many @GothamChess "guess the elo" videos).12. This is the worst is-even of all timeNEW TOOL: Rust (Bitcoin Style) AI is-even Features: - 🔥 BLAZING FAST 🔥 Rust library - AI-powered: Uses cutting edge Claude Opus 4.1 to determine if an integer is even - Bitcoin Style: Returns SHA256(result) (whole new architecture) - Beautiful Ratatui TUI to run examples13. Security conference CFP tracker (because I kept forgetting and missing deadlines)Made this to keep track of upcoming security CFP deadlines at cfp dot hex dot dance Please help populate the list with an easy PR!14. Chrome extension scannerA year ago I released @CRXaminer, a Chrome extensions security scanning tool. I wrote a blog post to reflect on the tool more:I wrote Task Unmanager: keeps killing processes Russian Roulette style, until your machine crashes16. Harness for scanning codeBuilding a harness to run scans with an agent. It is absolutely garbage. Completely useless. There’s literally 0 benefit to using it over plain Claude Code. Everything it can do, you can just do via Skills etc. Many were preaching the benefits of a harness, but I’m not sure.17. Wannacry for GBA“GAME BOY can’t get viruses” Oh, yeah? Well then, explain THIS- you're making some really cool things. keep it up. i love the aesthetics.
