What is it?

Traceway is an observability platform built natively on OpenTelemetry. It brings logs, traces, metrics, exceptions, session replay for web and Flutter, LLM/AI tracing, and on-call paging into one system. Applications send data over OTLP/HTTP to Traceway directly, so no separate Collector or vendor-specific SDK is required for backends.

It can be self-hosted with docker compose, using SQLite, DuckDB, or ClickHouse with PostgreSQL as storage, or embedded inside a Go application using SQLite. Exceptions are fingerprinted and grouped into ranked issues, and minified JavaScript, iOS, Android and Flutter crashes are symbolicated back to original source locations using uploaded source maps, dSYMs or R8 mappings.

The project also ships an agent-oriented read-only CLI and agent skills for Claude Code, Cursor and Codex, with opt-in write access for agents. It is MIT licensed and includes SLO tracking, alerting integrations, and a fleet overview across projects.

Key features

  • 01Native OTLP/HTTP ingest for logs, traces and metrics from any OpenTelemetry SDK.
  • 02Exception grouping by SHA-256 fingerprint, with source map support for webpack, esbuild and Vite.
  • 03Per-endpoint latency percentiles, throughput and error rate.
  • 04Session replay for web applications and Flutter.
  • 05LLM cost, token and conversation tracking via gen_ai attributes.
  • 06On-call rotations, escalation policies and paging via email, Slack, Pushover, Telegram or SMS.
  • 07SLO objectives with error budgets and burn-rate alerts.

Use cases

  • Debugging production exceptions in a web or mobile app with replay and symbolicated stack traces.
  • Consolidating logs, traces and metrics from microservices without running a separate Collector.
  • Monitoring LLM-powered features for cost, latency and conversation content.
  • Running a self-hosted observability stack on a single container with SQLite.

Quick start

  1. 1

    Clone the repository

    git clone https://github.com/tracewayapp/traceway
  2. 2

    Enter the directory and start with Docker Compose

    cd traceway && docker compose up -d

Things to know

  • Self-hosting the full stack requires running Docker and external databases unless you pick the SQLite or DuckDB image.
  • Profiling is marked experimental in the README.
