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/
