Typed relationship

langtrace alternative openllmetryOpenLLMetry by Traceloop works similarly to Langtrace in offering open-source observability tools for LLM applications.

Choose langtrace if…

  • langtrace is primarily TypeScript; openllmetry is Python.
  • License: langtrace is AGPL-3.0, openllmetry is Apache-2.0.
  • OpenLLMetry by Traceloop works similarly to Langtrace in offering open-source observability tools for LLM applications.
  • Tags unique to langtrace: ai, datasets, evaluations, gpt.
  • langtrace ships Docker support for self-hosted deployment.
  • When developing or using LLMs and frameworks where end-to-end visibility into every aspect of model performance is crucial.

When NOT to use langtrace

  • For teams that do not require real-time tracing and evaluations, as implementing Langtrace might introduce unnecessary overhead.
  • When working with non-LLM AI applications or other machine learning models, Langtrace’s specialized features for large language models may not provide much value.

Choose openllmetry if…

  • openllmetry is primarily Python; langtrace is TypeScript.
  • License: openllmetry is Apache-2.0, langtrace is AGPL-3.0.
  • OpenLLMetry by Traceloop works similarly to Langtrace in offering open-source observability tools for LLM applications.
  • Tags unique to openllmetry: artifical-intelligence, datascience, generative-ai, good-first-issue.
  • Use openllmetry when you need observability tools specifically tuned for GenAI and LLM operations integrated with OpenTelemetry.

When NOT to use openllmetry

  • Avoid using openllmetry in environments where dependency on Python is undesirable or where alternative languages are prioritized beyond Python's ecosystem.
  • Do not select openllmetry if you prefer tools that offer broader customization options for core observability features, as it specializes in integration with OpenTelemetry.

Do not select openllmetry if you prefer tools that offer broader customization options for core observability features, as it specializes in integration with OpenTelemetry.
Is langtrace or openllmetry more popular on GitHub?
openllmetry has more GitHub stars (7,377 vs 1,216). Stars measure visibility, not whether either tool fits your constraints.
Are langtrace and openllmetry open source?
Yes - both are open-source projects on GitHub (langtrace: AGPL-3.0, openllmetry: Apache-2.0).
Where can I find alternatives to langtrace or openllmetry?
GraphCanon lists graph-backed alternatives at langtrace alternatives and openllmetry alternatives (langtrace markdown twin, openllmetry markdown twin), ranked by typed relationship edges rather than popularity votes.
Is there a machine-readable version of this comparison?
Yes. The markdown twin at this comparison mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers.
Which is better maintained, langtrace or openllmetry?
langtrace: Slowing. openllmetry: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance.
