Hosted Backend

The Nimbus hosted backend runs the full pipeline on Railway — no local setup required for execution.

What's hosted

Component	Details
API	FastAPI on Railway, available at `api.get-nimbus.com`
Vector store	ChromaDB on a persistent Railway volume
Workspaces	Ephemeral containers per task, auto-cleaned after completion
Database	SQLite (tasks, repos, keys, automations, skills)

Pass --backend to any nimbus run command:

nimbus run "add rate limiting to the API" \
  --backend https://api.get-nimbus.com \
  --api-key $NIMBUS_API_KEY

Or set the environment variable:

export NIMBUS_BACKEND=https://api.get-nimbus.com
export NIMBUS_API_KEY=nim-...
nimbus run "add rate limiting to the API"
