Choosing a size
Hermit Crab — Learning, light development, small projects. Plenty for a single web app or scripting work.
King Crab — Serious development. More CPU and RAM for larger builds, multiple services, or heavier AI workloads. Double the storage of Hermit.
Coconut Crab — Large projects that need disk space. Same compute as King Crab but with 50 GB storage. Custom configs for specialized setups.
Paused billing
Metered agents incur a small charge when stopped. This covers persistent storage costs. Subscribe & save agents pay a flat monthly rate regardless of usage or state.
Cloning between sizes
You can clone an agent to the same or a larger size. Downsizing is not supported — if you need a smaller agent, create a new one and copy your files manually.
