Riju is an extremely fast online playground that lets users run code in hundreds of programming languages directly in the browser, with sub-second startup for interpreters and compilers. It is a self-hostable web service backed by containerized sandboxes, with a Monaco-based editor and terminal interface.
Use cases
- try out a programming language without installing it
- run a quick python interpreter in the browser
- compile and run obscure esoteric languages like INTERCAL
- share a scratch environment for code experiments
- test code snippets across many languages quickly
When to choose
- you want to experiment with a language instantly without local setup
- you need support for a very wide range of languages including esoteric ones
- you want a free, privacy-respecting online code runner
When to avoid
- you need persistent file storage or long-running programs
- you are on an IPv4-only network without a VPN
- you need production-grade isolation guarantees for untrusted code
