Run anything in the cloud

replace uv run with vmux run. your code runs in a container, and you can attach to it like tmux. free for the holidays, then $1/mo.

vmux run → cloudflare container → r2

↳ tmux session

uv tool install vmux-cli

vmux run python train.py
# ai bundles your code + deps via AST. runs up to 7 days (for now!).

vmux run -d python train.py
# detached. job keeps running. close your laptop.

vmux attach abc123
# back in your tmux session. from anywhere.

vmux run -d --preview python server.py
# port 8000 exposed → https://oibqm8ham8zq.purr.ge
# websockets work. deploy a full web app.

vmux ps
vmux logs -f abc123
vmux stop abc123

how it works

AST parses your imports, bundles only what's needed (10GB repo → 50KB)
uv run auto-detects deps from PEP 723, pyproject.toml, or requirements.txt
runs on cloudflare durable objects with 168h keepalive (indefinitely soon)
tmux inside container survives disconnects—come back anytime
websockets work for preview URLs (deploy fastapi, gradio, streamlit)
pre-baked image: pytorch, transformers, numpy, pandas, fastapi
ctrl+c detaches your client, job keeps running in cloud

each job runs in an isolated container · full network access · websocket support
real tmux with resize · preview urls on port 8000 · stream logs in real-time

no dockerfile · no server · no ssh · <100ms cold starts · gpus soon
