Do I need to install an SDK?
No. Flowlines reads from your existing trace store (Langfuse, Helicone, Arize, or any OTEL pipeline) instead of shipping an SDK into your agent. Setup is a five-minute read connection with zero code change.
Most observability tools ask you to install an SDK and wrap your agent so they can capture data at runtime. That means a code change, a deploy, added latency, and a dependency you have to maintain.
Flowlines doesn't. Your traces already exist in Langfuse, an OTEL collector, or a log you can export. Flowlines connects to that source and reads. Nothing runs inside your agent's hot path.
If you don't have any trace store yet, the fastest path is to stand up Langfuse (free, ~15 minutes) and connect that. A lightweight ingestion SDK is on the roadmap for teams who want to push directly, but it's never required.
