Product Snapshot
Langtrace is an open-source observability and evaluations platform from Scale3 Labs Inc. It provides SDK-based tracing, a web dashboard, and self-hosting options for AI app and agent workflows.
What You Can Do With It
- Capture OpenTelemetry-based traces from LLM apps and export them to Langtrace or another observability stack.
- Trace supported LLMs, frameworks, and vector databases across Python and TypeScript SDKs.
- Version prompts, compare prompt variants, curate datasets, and run evaluations on annotated or custom datasets.
- Self-host the stack with Docker, Docker Compose, Kubernetes, Azure App Service, or Railway.
Why It Stands Out
It combines open-source tracing, prompt management, and evaluations with both managed cloud and self-hosted deployment paths.
Tradeoffs To Know
- Growth pricing is per user and includes usage caps, so costs can rise with team size and volume.
- Self-hosting gives more control, but it also adds infrastructure and upgrade work.
- Teams evaluating procurement should confirm the current security and compliance posture directly because the public materials span product, docs, and blog pages.
