Compiles and runs code in around seventy languages with no sign-up.
Pick a language, type, press run. It covers the obvious ones and the awkward ones you occasionally need — Fortran, COBOL, Assembly, Prolog — supports stdin, and bundles throwaway databases for practising SQL. Useful for settling an argument about how a snippet behaves, or for an interview question you want to check. Programs run sandboxed with a short execution timeout and no outbound network, so it is not somewhere to test anything that calls an API.
Questions
Works the moment the page loads. No account, no email, no trial. Programs are killed after a few seconds and have no network access, so nothing that fetches will work.
Yes. OneCompiler sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
