Cloud Agents Start 3x Faster with Builds
By Steven Van ·
Agents do their best work when they start in a ready environment: repos cloned, dependencies installed, and your install script already run.
Cursor's Cursor is rolling out builds for Cloud Agents: ready-to-use copies of a development environment, with repos cloned, dependencies installed, and the install script already run, that Cursor prepares in the background. Agents boot into one of these instead of setting up from scratch each session, at no additional cost.
- Environments now boot 10x faster internally, with 3x faster time to first token. The install command should hold anything that can be prepared ahead of time, while the start command still runs when an agent is first prompted, for services that need to be fresh.
- If a bad commit or dependency update breaks a build, agents keep using the last successful one. The broken build never goes active, and the user is notified while agents keep working.
- A new Builds tab in the Cloud Agents dashboard shows build status, logs, commit SHAs, and which build each agent run used. Agents can also inspect and manage builds with built-in tools.
New environments use builds automatically. Existing environments can turn it on from the Builds tab by clicking Enable Builds, or by running the setup agent first to test the migration. Builds can also be triggered manually, and how stale a build can get before refreshing is configurable. Details are in the announcement.
