Behavioral Heatmap And Session Recording With User Interaction Tracking

via “session and user-level trace grouping with feedback aggregation”

Open-source LLM observability — tracing, prompt management, evaluation, cost tracking, self-hosted.

Unique: Sessions are first-class entities in the PostgreSQL schema with explicit foreign keys to traces, enabling efficient filtering and aggregation without full-table scans. User feedback is stored as a separate table with support for multiple feedback types (numeric, categorical, text) and timestamps, enabling temporal analysis of feedback trends within sessions.

vs others: More flexible than Langsmith for multi-turn conversation analysis because sessions can span multiple traces and feedback is aggregated at the session level, whereas Langsmith groups feedback at the trace level, making it harder to analyze conversation-level quality.
