Sentry Seer

What is Sentry Seer?

Sentry Seer is the debugging agent inside Sentry. It uses the errors, traces and logs Sentry already collects as context, so it can investigate new issues automatically and, in Sentry's words, have a pull request ready for review when you start work. It also answers plain-language questions about production data, even when no alert triggered the question.

Key capabilities of Sentry Seer

• Autofix: reads stack traces, traces root causes through your codebase and drafts a fix.
• Seer Agent: lets you ask what is wrong without gathering context or pasting stack traces.
• AI Code Review: checks pull requests against production failure patterns and comments only when a change looks risky.
• Issue scan: rates how likely an issue is to be fixable with a code change.
• Automatic fix attempts: can be configured to attempt fixes without being asked.
• Handoff to coding tools: send fixes to Claude, Copilot or Cursor.

How Sentry Seer works

Seer runs from the Sentry interface, and users are prompted to enable generative AI features on first use. It looks at an issue's telemetry, estimates whether a code change can fix it, and drafts the change. In Slack you can fix bugs from alerts and start incident investigations the team can see, and the Sentry MCP lets Claude Code, Cursor and Warp pull issues and apply fixes.

Who uses Sentry Seer?

Seer is for development teams that use Sentry across web frontend and backend, mobile and desktop. It supports the languages and frameworks Sentry supports, and fits teams that want root-cause analysis and review comments grounded in real production failures.

Sentry Seer pricing

Sentry lists Seer at $40 per active contributor per month, where an active contributor commits two or more pull requests in a connected repository. Seer requires a paid Sentry plan (Team, Business or Enterprise). Users on a Sentry trial can use Seer, though the trial length is not stated on the Seer page.

Sentry Seer alternatives

Snyk DeepCode AI is centered on code security analysis and fixes, whereas Seer is grounded in runtime errors and traces from Sentry. Ellipsis reviews pull requests and fixes bugs from the repository side, without production telemetry as its starting point. GitLab Duo is a broader AI assistant across the GitLab workflow, so it fits teams standardized on GitLab.
