Agentic Harnesses
Agentic harnesses are the orchestration frameworks that turn a raw LLM into an autonomous agent: planning, tool-use, memory, multi-agent loops. This directory lists the notable ones, each with a focused page so you can compare before you build. New launches get a post and a spot on the homepage timeline.
