Key Features

Smarter builds. Faster dev loops.

Unified Multi-Language Ecosystems

Automatically interfaces with Monorepos (Nx, Turbo), JavaScript (Bun, PNPM, NPM), Python (UV, Poetry, Pipenv), Rust (Cargo), Go, Java, Swift, PHP, Ruby, and generic tasks (Just, Make).

Sub-5ms Latency

Engineered in high-performance Rust, offering near-instantaneous command resolutions with absolute zero runtime interpreter overhead.

devrunner (dr) 4ms
npm run 120ms
yarn run 210ms

Conflict Resolution

When multiple lockfiles exist, devrunner automatically inspects system files and environment contexts to bypass conflicts gracefully.

AI Coding Assistants Integrated

Installer natively configures Claude Code, Codex, and OpenCode terminal hooks. Minimizes token bills up to 90% by substituting verbose sweeps with unified execution calls.

## devrunner integration
Use dr <command> as the universal execution driver.
Do NOT call npm, cargo, poetry directly inside LLM sessions.

Accelerate your development cycle.

Install devrunner today and optimize command execution. Built for rapid, zero-overhead workflow automation.
