Description

Laminar

Laminar (lmnr) is an open-source observability platform for LLM applications and AI agents: OpenTelemetry-native tracing, evaluations, datasets, labelling queues, full-text span search, and SQL access to all of your trace data.

This package runs the self-hosted open-source (Apache-2.0) Laminar stack as a single Cloudron app — the Next.js dashboard, the Rust ingestion/API server, and bundled ClickHouse (span analytics) and Quickwit (full-text search) — with PostgreSQL provided by the Cloudron addon.

What you get

  • OpenTelemetry-native trace ingestion over OTLP/HTTP, plus the Laminar Python/TypeScript SDKs.
  • Trace & span explorer with full-text search, a SQL editor, and dashboards.
  • Evaluations, datasets, and labelling queues for building and grading eval pipelines.
  • Single sign-on via the Cloudron OIDC addon (Better Auth), or passwordless local sign-in.
  • All trace data stays on your own server; nothing is sent to a third party.

Cloudron integration

Sign-in through Cloudron SSO (OIDC) when enabled; automatic backups of all state under /app/data; one-click updates; per-project API keys for SDK and OpenTelemetry-collector ingestion on a dedicated ingestion subdomain.

Recent Changes

  • [0.1.4]

  • Hardened backups: the bundled ClickHouse and Quickwit stores now live on dedicated volumes and are captured

  • by a consistent logical dump/restore, so automatic backups can't race live writes or abort mid-run.

  • Right-sized memory: 4 GiB default with an internal ClickHouse cap, measured for small/personal installs.

  • Trace ingestion is OTLP/HTTP only (protobuf or JSON) — simpler and a smaller attack surface than gRPC.

  • Ingestion is traces-only; the endpoint requires TLS (send OTLP/HTTP over https, not cleartext).

  • Added a pre-publish secret-scan release gate.

  • [0.1.0]

  • Initial release: Laminar 0.2.0 (open-source LITE profile) packaged for Cloudron.

  • Next.js dashboard (Better Auth) + Rust app-server (OTLP/HTTP + REST ingestion) + bundled ClickHouse and Quickwit; PostgreSQL via the Cloudron addon.

  • App-native OIDC single sign-on through the Cloudron oidc addon; passwordless local-email sign-in when SSO is off.

  • Trace ingestion on a dedicated subdomain, secured by per-project API keys.

  • Data-loss-critical encryption key generated once and preserved across updates and restores.
