What is HarnessRouter?
The unified interface for agent harnesses
HarnessRouter is the unified interface for agent harnesses. Its Harness Memory gives every agent its own long-term memory: pick a memory engine (Mem0, Graphiti, Hindsight, ReMe, or your own) and plug it into different agent harnesses like Claude Code, Codex and Hermes. Memory can be shared across harnesses, with fine-grained access control.
The Free plan includes 30 agent-work minutes a month with no card required, and you pay only while your agent works — waiting is free. A Community Edition is open source, and the platform is available on HarnessRouter Cloud.

HarnessRouter Key Features
Harness Memory
Every harness agent gets its own long-term memory, loaded when a session starts and recorded when it ends.
Shared across harnesses
Claude Code, Codex, Hermes and other harnesses share one memory, with fine-grained access control.
Four memory engines
Pick Mem0, Graphiti, Hindsight, ReMe or your own engine, all open source.
Safe by default
Memory is isolated per person, treated as data rather than instructions, and agents cannot delete it.
Open protocol
The open Harness Memory Protocol standardizes memory across harnesses; a Community Edition is open source.
