THE FLIGHT RECORDER FOR AI AGENTS
See the run.
Prove the record.
Trace agent calls, enforce gateway policy, and verify the audit trail from one open source control plane.
ILLUSTRATION · Interface based on Tracelane’s trace viewer; no customer data.
01 / REQUEST PATH
Recorded before dispatch.
Use an OpenAI or Anthropic compatible endpoint; an unavailable audit write returns 503 audit_unavailable before provider dispatch.
ILLUSTRATION · Paths show gateway behavior, not a live request.
02 / DROP IN
Change the base URL.
Keep your provider key and familiar client while Tracelane records the admitted gateway call.
Quickstart ↗from openai import OpenAI
client = OpenAI(
base_url="https://gateway.tracelane.dev/v1",
api_key="YOUR_TRACELANE_KEY",
)
response = client.chat.completions.create(
model="YOUR_MODEL",
messages=[{"role": "user", "content": "Hello"}],
)ILLUSTRATION · Replace placeholders with your configured model and key.
03 / POLICY
A verdict before the call.
Inline heuristic guardrails can allow, warn, or block at the gateway, with the verdict recorded.
Details ↗ILLUSTRATION · Verdicts and dispatch paths are schematic.
04 / OBSERVE
The whole request, inspectable.
A waterfall, transcript, and span inspector put recorded model and tool activity in context.
Details ↗ILLUSTRATION · Gateway spans may be single-span; nested activity depends on instrumentation.
05 / VERIFY
Evidence you can verify offline.
Gateway audit records form a SHA-256 hash chain; Ed25519 signs batches, and Rekor anchoring is best-effort.
Details ↗ILLUSTRATION · A UI state, not a live verification result.
ILLUSTRATION · Rekor inclusion is checked separately.
06 / DEPLOY YOUR WAY
Open core. Your call.
Start on Tracelane Cloud or run the Apache 2.0 core on your own infrastructure.
Self-hosting details ↗ILLUSTRATION · Deployment components and ledger durability differ by topology; see the guide.
