Self-deployed LLM tracing
LLM traces that do not expire.
Run FireTrace in your own Firebase account and keep every agent run, prompt and tool call until you choose to delete it. Infinite retention is time-unlimited, not storage-unlimited: capacity is bounded by your Firebase plan (1 GiB on the current free tier).

Yours, not rented
Deploy the Next.js app to Vercel and point it at a Firebase project you own. Traces live in your Firestore database; FireTrace has no servers of its own.
No expiry, ever
There is no TTL field, no cleanup job and no age-based deletion path. Traces stay until you delete them or your Firebase storage is full.
One POST per run
A small TypeScript SDK or a single curl call records a complete trace with nested spans, inputs, outputs, tokens, cost, errors and tags.
