The bug threw nothing. The user just gave up. Crumbtrail caught it.
Crumbtrail is capture middleware embedded in your app, watching for the signals of a user giving up — rage-clicks, retry storms, slow responses, abandoned flows. When one fires, the reproduction is already captured: every click, every request, and the exact row that changed. You get fix-ready context the moment it happens, not a support ticket three weeks later.
Tests. Alerts. And the user who quietly left.
CI tests
CI tests catch what you predicted could break.

Crumbtrail
Crumbtrail catches what your users gave up on.
A silent issue is the failure your other two legs structurally miss: no test predicted it, nothing threw, and the user closed the tab instead of filing a ticket. Crumbtrail replaces neither — it runs alongside your Sentry and watches the one place both are blind: what the user actually did.
Watch a silent issue get caught
No error fired. No ticket filed. Crumbtrail flags the diverging interaction and the exact row that changed — then hands the causal window to a coding agent.
Now watch it in the product
A pass through the dashboard on a silent one: a release makes toggling a single row overwrite every other row — 200 OK, no exception, tests still green. Crumbtrail compares the two releases, pins the exact query that changed, and hands your coding agent the fix bundle it uses to write the one-line fix.
The bug your agent would fix wrong
A revenue report reads $12K short — 200 OK, no exception, the numbers just look wrong. Blind, a coding agent patches working rollup code and the bug returns. Crumbtrail already has the session: a report_timezone flag diverged from baseline and pushed late-night orders across the date line. Your agent flips one flag instead of shipping a diff.
One captured session. Everything your agent needs.
Detection is just the start. Follow any thread below.
How detection works
Behavioral detectors, complete correlated sessions, and row-level database diffs — assembled into fix-ready context and handed to your coding agent over MCP.
See how it worksWhere Crumbtrail fits your day
The captured session turns three familiar dead ends into a lookup — the reopened ticket your agent fixed wrong, the 2am pager with no repro, the support escalation engineering can't reproduce.
