Cursor: Cloud Agents builds for faster startup and resilience

Cursor introduces builds—pre-prepared environment snapshots that Cloud Agents boot from instead of setting up from scratch each session. Builds are cached, automatically refreshed, and agents fall back to the last successful build when a new one fails. Included with Cloud Agents at no extra cost.

  • Agents start from a pre-built environment instead of installing dependencies fresh each session
  • Cursor keeps warm copies ready for 3x faster time to first token, 10x faster environment boot
  • Failed builds never become active; agents continue using the last successful build while the user debugs
  • Each environment has a Builds tab in the dashboard showing status, logs, commit SHAs, and per-agent build attribution
  • New environments use builds automatically; existing environments can enable via the Cloud Agents dashboard
  • Configurable stale-build refresh threshold; manual build triggering and debug agent support
