OpenTelemetry-native platform combining logs, traces, metrics, session replay, exceptions, and AI tracing under a single MIT license with no open-core restrictions.
Key Takeaways
Self-host via docker compose up -d or embed inside a Go process using SQLite; no Collector or per-language vendor SDK required.
Full feature set includes LLM cost/token/latency tracking across OpenRouter and OTel-compatible AI gateways, plus source-mapped exception grouping and session replay for web and Flutter.
Storage is ClickHouse + PostgreSQL in standalone mode or SQLite in embedded mode; frontend is SvelteKit 2 + Svelte 5; backend is Go 1.25 + Gin.
Alerts (Slack, GitHub, email, webhook), Apdex scoring, Impact-Score endpoint ranking, and multi-tenant RBAC ship in the open repo with no paid tier gating.
Hacker News Comment Review
Commenters flag that the DIY OSS comparison column targets Prometheus + Loki + Tempo but the real competition is SigNoz and ClickStack, both ClickHouse-backed and OTel-native.
OpenObserve comes up as an alternative, particularly for Ruby stacks where OTel metrics and logs support is still immature.
