About OneCompiler
OneCompiler is an online editor where you can write, run and share code in many programming languages. It works in the browser with no install, and the same engine can be used through embeds and APIs.
What it does
Pick a language, write code and press run to see the output. Projects can include several files, such as HTML, CSS and JavaScript. Developers can embed the editor into a website or call the run APIs from their own backend to execute code.
Key features
- Run code in more than 110 languages
- Embed the editor in your own website as an iframe
- Call APIs to run code from your backend
- AI agent that edits files in the editor with rollback checkpoints
- Starter templates for web and database stacks
Who it's for
Students and self-taught programmers who want a quick environment, and educators or product teams that need an embedded code runner. Teams building coding courses or challenges may find the embed option useful.
Pricing and good to know
The editor is free to use in its basic form, and the site lists paid plans for bigger needs. The AI agent makes changes in place, and each change can be rolled back from a checkpoint, which helps when reviewing its edits. Check the plan limits before relying on the API for production traffic.
