OpenLIT
OpenLIT is a self-host OpenTelemetry LLM observability desk: you send traces and open a conversation + span-attributes pane (tokens, $, model).
OUR TAKE
Pick OpenLIT for teams who will self-host OpenLIT at $0 (you bring compute) — not Langfuse first unless they want that Cloud tile. $0 is the license, not your cluster.

Instead, try
Langfuse if traces you can self-host when you want Langfuse’s public Cloud $; Phoenix if local-first OTel traces when you want Phoenix $0
