Kairos
Finic's open-source (Apache-2.0) real-time fraud and risk decisioning platform, an alternative to Sift, Sardine, Riskified and SEON: one call returns approve, step up, review or block for each sign-up, login, order, payment or payout, with a risk score and reasons. Combines Finic's Grayson decision model, which answers plain-language questions like 'Is this email throwaway?', with logistic regression and gradient-boosted trees. An MCP server lets Claude Code, Cursor or Codex build workflows and run model experiments on your data. TypeScript and Python SDKs, a CLI and HTTP API; Kairos Cloud or self-host with Docker.
