Drives smolvm programmatically over its local HTTP API (smolvm serve) instead of the CLI: create machines, exec and stream commands, move files in and out, and tear them down. Use when building a client, harness, agent tool or MCP backend over smolvm; when a…
Runs a Docker daemon inside a smolvm machine and shows it working there, which is what tools that call Docker themselves need, such as a test suite that starts containers, an image build, or a coding agent that launches containers. Use when dockerd will not…
Turns an image, or a machine already provisioned, into a single self-contained artifact that runs on another compatible host. Use when shipping a prepared environment as one file, when a packed artifact runs but the state installed into it is missing, when…
Stops every smolvm machine a session started, removes smolvm's state, and proves the host is clean. Use after any smolvm session; when a machine seems to have survived a Ctrl-C or a crash; when disk space has disappeared; when uninstalling smolvm; when…
Keeps a persistent smolvm machine with its dependencies already installed and re-enters it cheaply across sessions. Use when a project needs an isolated development environment that survives stop and start; when deciding what belongs in a Smolfile's init…
Saves a running smolvm machine as checkpoints on a schedule, keeps a bounded history, restores any generation in it, pauses and resumes machines without losing running processes, and branches a warm machine into children with a checkpoint of the exact point…
Runs untrusted code in a throwaway smolvm microVM against a repo it must not modify, with no network unless explicitly granted, and collects artifacts from a writable output directory. Use when executing an agent's generated script, a pull request's test…
Runs a coding agent (Claude Code, OpenCode, Codex or any other) inside a persistent smolvm machine with the project mounted, so it can run with full permissions without touching the host. Use when someone wants to sandbox their coding agent, run it in…
Gives a workload in a smolvm machine an API key or token it can use but never read, by binding the credential to named HTTPS hosts so the guest holds only a placeholder and the host substitutes the value on the way out, then proves on the host that the value…
Runs CUDA compute workloads inside a smolvm microVM against a real host NVIDIA GPU, using smolvm's --cuda API remoting. Use when a workload in a machine needs a GPU; when nvidia-smi or /dev/nvidia* is missing inside a --cuda guest; when a CUDA program in a…
Installs smolvm from a published release and proves the host can actually boot a microVM before any other work starts. Use when setting smolvm up on a new machine, a CI runner or an agent's own environment; when a first boot fails with krun_start_enter -22,…
