Does Tessary read my Langfuse account?
No. Tessary has no connector for Langfuse or any other vendor, and it never reads an account, an API key, or a dashboard on your behalf. Traces reach Tessary the same way they reach Langfuse in the first place: your agent already emits OpenTelemetry spans, and you add Tessary as a second exporter alongside whatever you have today, pointed at Tessary’s own OTLP endpoint. Langfuse keeps receiving everything it receives now; nothing about your existing setup changes or gets replaced. That also means there’s no export job and no scheduled sync pulling your history out of Langfuse’s database, Tessary only sees what your instrumentation sends it going forward. If you’d rather not touch application code, the same fan-out can happen at an OpenTelemetry Collector instead: one incoming stream, two outgoing exporters.
