Overview
Sentr captures exceptions from web and server runtimes, groups them into issues, and surfaces the ones that actually matter. Built to give small teams the essentials of a full observability suite without the price tag or the noise.
Impact
- Cut mean time to detection from hours to under a minute for the pilot team.
- Grouped 40k+ raw events into ~200 actionable issues per week.
- Shipped a type-safe SDK adopted across three internal services.
What I learned
- Designing an ingestion pipeline that stays cheap under bursty traffic.
- Modelling error fingerprints so unrelated stack traces never collide.
- Keeping a tRPC API ergonomic as the surface area grew.
