Bugs caught in PR with an exact fix suggestion
Traceback is the last line of defense
01Small teams

No QA team. No problem.

The situation

You're a 5-person team moving fast. There's no dedicated QA role. Before every release, the developer who wrote the feature clicks through it themselves. This doesn't scale and catches maybe 40% of what breaks.

How Traceback helps

Traceback becomes your QA engineer. Describe the flows that matter — signup, checkout, onboarding — and they run automatically before every deploy. You stop being the last line of defense.

QA that runs on every deploy, not just when someone remembers.
02GitHub workflow

Never break main again.

The situation

A developer merges a PR that looks clean. Tests pass. Then a user reports the checkout flow is broken — a CSS class rename two weeks ago silently broke a Playwright selector, and nobody noticed until a customer did.

How Traceback helps

Traceback runs on every PR against the preview deployment. Results post as a status check. If checkout breaks, the merge is blocked. The developer sees it before it ever hits main.

Failures caught in PR, not in production.
03Production monitoring

Know before your users do.

The situation

Production is live. Something breaks quietly — a third-party payment script stopped loading, an auth edge case shows a blank screen, a config change silently broke email delivery. A user tweets about it four hours later.

How Traceback helps

Traceback runs smoke tests against production on a schedule — every 15 minutes for critical flows. When a test fails, a Slack alert fires immediately with what broke and a link to the full report.

Mean time to detect goes from hours to minutes.
04AI coding agents

AI agents that test their own work.

The situation

An AI coding agent writes a feature and deploys it to a preview URL. There's no human to click through and verify. The agent can't see the running application. Bugs ship silently.

How Traceback helps

The agent calls Traceback's MCP server: run_test → get_report → debug_failure. It reads the structured failure report with a fix suggestion and applies the fix before merging. No human in the loop.

Code that ships already tested. No human in the loop.
05Critical user flows

Your signup and checkout work. Every time.

The situation

The two flows that kill your business if they break are signup and checkout. They touch authentication, email delivery, payment processing, and state management. One broken component across any of these and users churn silently.

How Traceback helps

Autonomous mode navigates these flows end-to-end — real browser, real form fills, real state. It catches broken email verification, payment form errors, redirect loops, and anything else a user would hit.

Your most important flows tested on every deploy.
06Refactoring safely

Refactor confidently. Tests adapt automatically.

The situation

You're migrating a component library, updating a design system, or restructuring state management. The behavior should be identical — but with hundreds of UI changes, how do you know nothing broke?

How Traceback helps

Deterministic tests with self-healing selectors adapt to UI changes automatically. HEALED steps tell you what changed without requiring test updates. You see a diff of selector changes, not a sea of red failures.

Refactor at full speed. Traceback tells you if anything actually breaks.
