About
Tracelane is an open-source, self-hosted LLM gateway written in Rust that is model agnostic. It lets teams add controls and guardrails, observe production traffic, and keep a tamper-evident ledger of what agents did, aimed at auditors who want more than log files as evidence.
At a glance
Tracelane records model and agent activity routed through its gateway and can export a ledger for offline verification. It is worth evaluating when you need to reconstruct what an agent called and check whether the audit record changed.
Good fit
Teams routing agent workloads through a gateway and able to define what traces may retain.
Consider something else when
Pass if traffic cannot go through a proxy or if you require every request to be blocked by policy without configuring enforcement.
Start here
Send a synthetic request with a harmless tool call through a test gateway. Inspect the resulting trace and verify the exported ledger.
Cost and requirements
The Apache-licensed project documents self-hosted and hosted options. Budget for storage and model usage, and configure the relevant gateway credentials.
Limits to know
The gateway only observes traffic routed through it. Full capture can retain sensitive content, and the default guardrails flag events without necessarily blocking them.
