Usage

vmux run python train.py
# like uv run, but in the cloud. you get a tmux session.

vmux run -d python train.py
# detached. close your laptop. job keeps running (up to 7 days).

vmux attach abc123
# back in your tmux session. from your phone, another laptop, wherever.

vmux run -d -p 8000 python server.py
# expose a port, get a preview URL. websockets just work.

vmux ps
vmux logs -f abc123
vmux stop abc123

How it works

• AST parses your imports, bundles only what you need (skips .git, venvs, checkpoints, etc.)
• auto-detects deps from pyproject.toml, requirements.txt, or PEP 723 inline scripts
• editable packages? we find them, bundle them, install them (transitive deps too)
• runs on cloudflare containers with 168h keepalive
• real tmux session inside. survives disconnects. reattach from anywhere.
• pre-baked image: pytorch, transformers, numpy, pandas, fastapi

Limits

• 0.25 vCPU, 1GB RAM per job
• 2GB disk (ephemeral, R2 mount soon)
• 7 day max runtime (indefinitely soon)
• outbound network unrestricted, inbound via preview URLs
• experimental: some jobs may be randomly evicted

Pricing

Free for the holidays, then $2/mo.
