Fact0

Self-hosted audit history and execution replay for AI agents

Local-first capture

Run the API, dashboard and PostgreSQL in your own environment via Docker Compose, then point your agent at the local instance with an API key. Data and signing keys stay with your installation.

Two entry points, one history

Record Python agents through the SDK (execution spans, tool results, supported model content, audit events) and Claude Code sessions through the collector plugin, then inspect both in the same workspace.

Execution graphs and replay

Follow a run through a graph, a timing waterfall and recorded spans, then step through saved events at your own pace. Replay reconstructs the record without re-running the agent.

Hash-chained audit records

Check the consistency of stored events against their hashes and preceding links, with capture gaps reported visibly rather than hidden.

Strengths & Pros

+Open source under the MIT license and fully self-hosted, so sensitive prompts and source code never leave your infrastructure
+Unusually transparent documentation that states capture limitations and what audit verification actually proves
+Docker Compose setup with a one-owner, one-workspace model makes getting started quick and scriptable
