A native, keyboard-first coding-practice IDE in idiomatic Rust, powered by GPUI. Practice, debug, ask your local AI agents, and prepare for contests in one calm workspace.
Built to follow your display’s refresh rate; actual frame cadence depends on your hardware and workload.
Linux & macOS — copy into your terminal; the installer downloads and launches leet.

| Deterministic visual debugger | Your local AI agents |
|---|---|

 |
- Deterministic debugging. Record execution, step forward or back, inspect variables and visual state, and replay the same run. Python and C++ traces include contest stdin programs.
- Local AI, native UI. Use your installed agents in chat, solution reviews, hints, complexity analysis, and visual walkthroughs. Choose providers and models without leaving the problem.
- Contest companion. Import Competitive Companion/CPH problems and samples; practice Codeforces and CodeChef alongside LeetCode and NeetCode.
- An editor that stays out of your way. Language-server support, syntax highlighting, saved problem tabs, local cases, results, and Git-backed solution history.
- Roadmaps and offline practice. NeetCode 150 is the default. The public SQLite bundle includes full NeetCode 150 and 100 CodeChef practice statements/samples; other catalogs have metadata and fetch statements on demand. Coverage & provenance →
- Rust + GPUI. Native rendering, compact panels, progressively disclosed controls, and keyboard navigation. Both application crates forbid unsafe Rust.
