runr

Automatically set up and run any GitHub repository using AI-powered dependency resolution.

runr https://github.com/karpathy/nanoGPT

That's it. runr clones the repo, reads every dependency file, resolves conflicts via an LLM, creates an isolated virtual environment, installs everything, and runs the project — self-healing up to 5 times if anything goes wrong.

Install

pip install runr
# or, for latest:
pip install git+https://github.com/runr-cli/runr

Requires Python 3.10+. Optionally install uv for faster installs:

pip install uv

Setup

Set your Groq API key (get one free at console.groq.com):

export GROQ_API_KEY=gsk_...

Usage

# Run a GitHub repo
runr https://github.com/karpathy/nanoGPT

# Run a local repo
runr ./my_local_project

# Force Python version
runr https://github.com/user/repo --python 3.11

# CPU-only (skip CUDA deps)
runr https://github.com/user/repo --no-gpu

# Preview plan without running
runr https://github.com/user/repo --dry-run

# Override entry point
runr https://github.com/user/repo --entry src/train.py

# Verbose (shows install logs + resolved requirements)
runr https://github.com/user/repo --verbose

# Private repo
runr https://github.com/org/private-repo --token ghp_...
# or set GITHUB_TOKEN env var

How it works

Caching

Resolved requirements are cached in ~/.runr/cache/ keyed by a SHA-256 hash of all dependency files. Same repo + same deps = instant resolution skip. Use --no-cache to force a fresh resolve.

Logs

Full logs are written to ~/.runr/logs/<repo>_<timestamp>.log.

Environment detection

runr automatically detects:

• Python version and OS/arch
• CUDA version (nvcc --version, nvidia-smi)
• GPU presence
• Already-installed packages (avoids re-pinning what's there)

Supported dependency files

• requirements.txt
• requirements-dev.txt
• setup.py
• setup.cfg
• pyproject.toml
• environment.yml (conda)
• Dockerfile (extracts RUN pip install lines)
• Implicit imports scanned from all .py files
