We all know that producing code is easier than ever thanks to the abundance of AI coding tools and agents. The post Cursor acquired Firetiger. A month later, Cursor launched a bot that tracks code changes through to production. appeared first on The New Stack .
After writing code, the challenging aspect often involves ensuring the changes are safe for deployment, identifying any issues in production, and determining the cause of any problems. This is where Cursor's new agent, Rollouts, comes in. Launched a month after SpaceX's acquisition of Cursor for $60 billion, Rollouts allows developers to quickly and reliably get code into production.
Firetiger, a startup that Cursor acquired, built AI agents that monitor software changes from pull request through deployment. Firetiger's co-founder, Rustam Lalkaka, noted that while coding agents had greatly reduced the effort of creating software changes, the risks associated with deployment had remained unchanged.
Rollouts functions as an agent, or "bot" as Cursor describes it, designed to monitor code changes in production. It works by examining proposed code changes when a pull request opens, determining what systems might be affected, and creating a monitoring plan to assess the change's impact. Developers can then review and adjust this plan before the code is deployed.
Once the change is deployed, Rollouts checks the new telemetry against the monitoring plan, providing one of three verdicts: verified healthy, regression detected, or inconclusive. If a regression is detected, Rollouts can identify the change, alert the developer responsible, and potentially open a revert pull request for review or hand the issue to a Cursor cloud agent for a fix.
Currently, Rollouts cannot merge fixes or roll back deployments itself, but it can pause a progressive rollout. Cursor is also integrating Rollouts with feature flags to directly adjust traffic reaching a change, and support for release trains and deployment freezes is in development.
In addition to Rollouts, Cursor has introduced an upgraded Security Reviewer bot. This bot automatically inspects pull requests for security vulnerabilities, authentication issues, privacy risks, and prompt-injection attacks. It then provides a severity rating, attack path, and proposed fix. The bot analyses pull requests within the context of the wider codebase, focusing on exploitable issues and providing developers with a speedup of 21% in review time from 4.8 minutes to 3.8 minutes.
Both Rollouts and Security Reviewer are available through Cursor's Automations tab for customers on Teams and Enterprise plans.
