Keel

Keel is a context layer for AI agents in vertical SaaS that ingests domain events and constructs a bitemporal context graph per tenant. It exposes five common tools for every agent to read and write over multiple protocols and SDKs, enabling multiple agents to share the same event-sourced customer context efficiently. Keel supports event ingestion from sources like Postgres CDC, webhooks, Kafka, and more, and offers SDKs in TypeScript, Python, Go, and PHP. It is designed to reduce duplicated pipelines and context definitions when deploying multiple AI agents in a product.
