vs AI engineering platform
Flowlines vs Langfuse.
Choose Flowlines for a focused workflow around user intent, recurring issues, and MCP journeys. Langfuse already offers tracing, user and session metrics, prompt management, and evaluations. Connect Langfuse to Flowlines through read-only polling or compatible OpenTelemetry export when you want that additional behavioral analysis.
User analytics and trace analysis
When to choose Flowlines.
You need a ready-made workflow for recurring issues, user intent, affected users, and MCP journeys on top of your telemetry.

Where Langfuse fits
Keep Langfuse for prompt management, experiments, scores, and customizable production metrics. It already supports user and session analysis.
What to test first
Connect a project through read-only polling or a compatible second exporter. Compare how quickly your team can move from a recurring problem to affected sessions.
If your next question is “which user need keeps failing?” rather than “what happened in this trace?”, start with Flowlines. Its issue, user, and MCP views connect recurring behavior to the sessions your team can investigate.
Flowlines polls Langfuse read-only or receives the same spans through a second OpenTelemetry exporter, then turns them into recurring issues across sessions, user and intent rollups, and the affected production sessions. Langfuse already supports users, sessions, metrics, and evaluations; the distinction is the workflow, not a claim that it cannot analyze production data.
