Sentry Seer
Sentry Seer: Seer is Sentry's AI debugging agent that finds the root cause of production errors, drafts the fix as a pull request and reviews code changes.
Seer is the AI agent built into Sentry, the error and performance monitoring service, for engineering teams that want bugs diagnosed with production context. Autofix scans issues as they arrive, combines the stack trace, traces, logs and profiles with the connected codebase to find the root cause, and can open a pull request with a fix. Seer Agent, launched in April 2026, answers plain-language questions about errors and performance and can create dashboards, monitors and alerts. Code Review checks pull requests against failure patterns Sentry has already seen in the app and flags changes likely to break. Analyses can be handed to Claude, Copilot or Cursor, and investigations can start from a Slack alert. Seer works with repositories on GitHub.com and GitLab.com and is an add-on to the paid Team, Business and Enterprise plans.
