LeetCo

What it does

LeetCo 🚀 is a Chrome extension that brings company-wise insights directly to LeetCode problems, without requiring LeetCode Premium. It shows which companies have asked a problem, displayed as clean badges with logos, right where you’re solving. No tab switching, no paywalls. Built for students and developers who want to prepare smarter, focus better, and save money while grinding DSA.

  Openleetcode – Local LeetCode runner where tests live in the repo19d ago · github.com · ▲73

  You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
