Practice like a real SWE.
Multi-file workspace, real execution, and career-focused projects — built to match how engineers actually work.
Why real-swe
At work, you use all kinds of coding skills — not just algorithms. real-swe is built for the messy, real-world stuff: reading code, structuring solutions, and shipping.
Solve problems the way you would on the job: structure files, refactor, and iterate.
Run code and get feedback quickly so you can focus on thinking like an engineer.
Build confidence with projects and repo-based quizzes designed for interviews.
In-browser IDE
Create files, run code, see output, and ship a clean solution — right in the browser.
- Multi-file workspace with an entry point
- Fast feedback loop: run, debug, iterate
- Output + results in the same place
