Capture the failing edge
Select one trace, lock dependency responses, and store only the fields your redaction policy allows.
Production replay for API teams
Turn a failed request into a local repro in 90 seconds.
Tracepin captures the headers, dependency calls, feature flags, and sanitized payload shape behind one production failure, then gives your team a deterministic replay bundle.

Dependency mismatch
Replay found a stale tax quote from Stripe Tax mock. Update fixture tax_quote_042.json or pin the incident bundle.
Built around the debugging path senior engineers already take.
No screen recordings, no giant session dumps. Tracepin keeps each incident bundle small enough to audit and complete enough to reproduce the failure without production access.
Replay beside your code
Run the same request against localhost, CI preview, or a branch deploy with headers and flags intact.
Ship the proof
Attach replay results, fixture diffs, and compliance-safe metadata to the pull request.
Specific enough for incident response. Quiet enough for daily use.
The product page exposes the controls teams care about: redaction, fixture scope, dependency status, and exact replay output.
Replay bundle contents
| Artifact | Stored | Status |

Start with one service. Expand when the incident volume proves it.
Simple deployment: OpenTelemetry collector plugin, replay CLI, and a hosted bundle vault. No new tracing vendor required.
