Probie and Sentry Seer

What Sentry Seer does

Seer is the AI debugging agent inside Sentry. It starts from an error or performance issue that Sentry has already captured, finds the root cause, and can open a pull request with a fix.

• Root-cause analysis for issues Sentry already captured: exceptions, performance problems, and traces.
• Autofix that writes a pull request against a connected GitHub repository.
• Lives inside Sentry, so it uses the stack traces, breadcrumbs, and releases Sentry already has.
• Priced as an add-on to a Sentry plan; Sentry publishes a list price of $20 per month plus usage on its pricing page.

What Probie does

• Passive session capture on web, Expo, and Swift: rage clicks, dead clicks, stuck loading, form friction, JavaScript and fetch errors.
• Groups sessions that hit the same problem into one issue with the evidence attached.
• Opens a pull request with a regression test for a person on your team to review.
• Keeps a behavior baseline per route and flags the route if the friction returns after the merge.
• Inspects any public website for free, without an account.

When each fits better

Pick Sentry Seer when You already run Sentry, your problems show up as exceptions, and you want fixes proposed on the issue page you already use.

Pick Probie when Your losses are silent: users give up on a form or a button and nothing throws. You want the pull request to arrive with the sessions that prove the problem.
