Trace-first debugging
Start from a failed request and follow every span across services, jobs, queries, and third-party calls.
Request-aware observability for backend teams
Understand backend failures in seconds
Grepline connects API requests, database queries, background jobs, and third-party calls into one clear execution timeline — so you can find the root cause faster.
API traces • Database queries • Background jobs • Third-party calls
Production ready workflows
Built for developers who need answers when production breaks
Grepline follows the real debugging loop: capture the full execution path, surface the failing span, and explain what caused the request to fail.
Designed for backend teams
Capture the execution path across APIs, workers, databases, and external services without stitching signals manually.
Production failure context
Connect API traces, database spans, worker jobs, external calls, and root-cause summaries in one view.
Built for production backends
Every failure has a path. Grepline shows it.
Full request timelines
Follow every API request across middleware, services, queues, and external calls in one ordered view.
Database query visibility
See slow queries, duplicate calls, rollbacks, and the code path that triggered them.
Background job tracing
Connect async workers and scheduled jobs back to the original request or system event.
Root cause explanations
Grepline highlights the span that broke the flow and explains the failure in plain developer terms.
Stop digging through scattered logs.
See the full execution path of every request, job, and failure in one place.
