ErrSight helps engineering teams see every error before their users do.

This is the official blog of ErrSight, a real-time error tracking and log management platform for production applications. We automatically capture exceptions, group duplicates through fingerprinting, and attach the full context of which user hit which error, so you can fix the right things first.

What ErrSight does

  • Automatic exception capture from Rails, Python (Django, Flask, FastAPI), Rust, JavaScript/React, and any language via the REST API.
  • Fingerprinting & deduplication: similar errors collapse into a single, actionable issue instead of a flood of duplicates.
  • Terminal-style live log viewer with infinite scroll and keyword search.
  • Automatic user context: ID, email, session, and plan attached to every event.
  • Triage built in: mark, assign, and snooze issues to keep the noise down.
  • Low overhead: background event batching with sub-millisecond async cost.

Why teams switch

Unlike Sentry, Rollbar, and Bugsnag, ErrSight uses flat, predictable monthly pricing with no overage fees. A spike in errors never turns into a surprise bill. Integration takes about two minutes, there’s a perpetual free tier for small projects, and the core is open source (AGPLv3) and self-hostable via Docker Compose and Postgres.
