About

Langfuse is an open source LLM engineering platform to help teams collaboratively debug, analyze and iterate on their LLM Applications. Observability: Instrument your app and start ingesting traces to Langfuse Langfuse UI: Inspect and debug complex logs and user sessions Prompts: Manage, version and deploy prompts from within Langfuse Analytics: Track metrics (LLM cost, latency, quality) and gain insights from dashboards & data exports Evals: Collect and calculate scores for your LLM completions Experiments: Track and test app behavior before deploying a new version Why Langfuse? - Open source - Model and framework agnostic - Built for production - Incrementally adoptable - start with a single LLM call or integration, then expand to full tracing of complex chains/agents - Use GET API to build downstream use cases and export data

About

iFixAi is an independent auditing platform for AI agents designed to test whether an agent does the job it was assigned, stays within its permissions, follows required workflows and approvals, respects organizational roles and boundaries, and produces behavior that can be reproduced and defended. It goes beyond observability, evals, and benchmarks by examining whether an agent can still expose confidential information, override decisions, misuse tools, or act without authorization even when standard checks look good. Its multifaceted audits cover more than 64 categories of AI misalignment across AI red teaming, operational assurance, philosophical, ethical, and sociological dimensions, including prompt injection, policy violations, tool invocation governance, principal fidelity, epistemic integrity, fairness governance, stakeholder conflict, influence, and systemic risk. Teams can connect agents through GitHub or MCP without first building a manual eval harness or embedding an SDK.

Pros & Cons from Real Users

Pros

  • I like that this is exclusively designed for LLMs only, so it takes a lot of clutter out of having to deal with features to do with rest of the models. Scores are very comprehensive including the ones related to query/response, ability to find rag relevance, cost related metrics which other tools typically do not offer and comprehensive trace function.

Cons

  • There wasn't much but if I have to highlight something here, self hosting was difficult. And the main dashboard can have drill downs to take it to relevant sections in traces/generations etc
