Keel is an open-source Rust harness for AI coding agents that manages auditable acceptance gates and durable memory across sessions. It records falsifiable checks, tracks whether gates have fired, and projects retained knowledge into agent-readable files for developers.
Overview
8 featuresIn the Frameworks & runtimes space, keel takes a focused approach. It focuses on preventing AI coding agents from stopping unreliably, weakening tests, or losing knowledge between sessions. It is built as an open-source project for developers building or supervising AI coding agents. keel is open source under the Apache-2.0 license. It runs on the web, macOS, and the command line, and it can be self-hosted.
Behind keel is Daneb, and it first shipped in 2026. Development happens publicly on GitHub with 77 commits in the last 90 days. Key capabilities include acceptance gates, falsifiable oracles, and durable memory.
