Langfuse UI : inspect and debug complex logs, user sessions and user sessions Langfuse Prompts: Manage versions, deploy prompts and manage prompts within Langfuse Analytics: Track metrics such as cost, latency and quality (LLM) to gain insights through dashboards & data exports Evals: Calculate and collect scores for your LLM completions Experiments: Track app behavior and test it before deploying new versions Why Langfuse? - Open source - Models and frameworks are agnostic - Built for production - Incrementally adaptable - Start with a single LLM or integration call, then expand to the full tracing for complex chains/agents - Use GET to create downstream use cases and export the data

Description

evalship reviews the LLM evals in a GitHub repository, then reports on every pull request what those evals say. At setup, a coding agent follows evalship's prompt: it reads every scorer, judge and prompt, lists the flaws that would let a bad change pass (for example a privacy score too small to ever fail a reply), gives a fix for each, wires the evals into GitHub Actions and opens a setup pull request. After that, each pull request gets a comment with the evals the change really broke and the likely cause. Flaky evals are set aside by checking them against the default branch's history, and changed prompts or LLM calls that no eval exercises are flagged. An evalship status check can gate the merge. Evals keep running in the team's own GitHub Actions with its own keys, and evalship reads the results file from pytest, Vitest, Jest, promptfoo, Langfuse, Braintrust or LangSmith, next to whichever eval platform the team already uses. A dashboard per repository shows what needs attention, and a weekly report sums up the regressions caught and what the evals cost. Public repositories are free; paid plans start at $19 a month.
