I kept bouncing between an online IDE, a SQL sandbox, and a JWT debugger — so I built one place for all of it.
Codeground AI: free browser IDE for 15+ languages (Python, Rust, Go, JS…) with a built-in AI assistant — chat with your code to explain, refactor, generate tests, and debug from run output. Plus DB playgrounds (Postgres, MySQL, Mongo, Redis), shareable snippets, interviews, and epoch/JWT/JSON/SQL tools.
No install. https://codeground.ai/
This is the 3rd launch from Codeground AI. View more
Dev Break Arcade
Launching today
Built Dev Break Arcade after staring at the IDE too long.
9 games in the browser — Infinite Drive, Neon Snake, Flappy Commit, Bug Breaker, Boring Chess (multiplayer), Cache Hit, Bit Merge, Round Trip, Mine Diff.
No accounts. No installs. Open https://codeground.ai/games/ and play.
Chess has shareable rooms so you can challenge a teammate between PRs.
Would love feedback on which game you actually use as a break ritual.

Spent a few minutes poking around the Postgres playground and the JWT decoder and they both just work without any setup fuss. The AI chat inline with the run output is a really nice touch for quick debugging.
honestly really solid setup, the all-in-one angle is super useful. one thing i'd love is the ability to set custom data retention on shareable snippets, like auto-expire after a week or a set number of views. right now i'm a bit hesitant to paste anything with real credentials for interviews even though the tool is great.
