Evidence-grade, not just observability.

Flight Recorder is a tamper-evident, cryptographically signed, hash-chained audit trail for AI agent activity — prompts, outputs, tool calls — built to survive an examiner's or regulator's scrutiny, not just a dashboard.

Unlike LLM-observability dashboards (Langfuse, Helicone, Bifrost), every record is Ed25519-signed and chained to the one before it, checkpointed independently, and exportable as a self-contained regulator pack mapped to EU AI Act Article 12, ISO/IEC 42001, FINRA Rule 17a-4(f), and SOC 2 CC7.

Get started

Run it yourself, free:

pip install -e .
export FLIGHTRECORDER_DEV=1   # local trial only; production needs a real key-encryption-key

Then, in Python: from flightrecorder import Recorder, create a Recorder(), and call .record(...) — writes to a local ledger file, no network required. Full source and docs on GitHub, Apache-2.0.

Or have us host it: email support@ripplarity.com with which tier you want, and we'll set up a hosted workspace for you.
