Unreal Agent
Unreal Agent is an async-first agent harness from Unreal Labs, a team researching how to make agentic workflows efficient. The library handles inputs with stable IDs and deduplication, append-only sessions that can be forked, and a coordinator that manages each model turn and translates tool calls into operations. It ships with a cloud agent runner, a terminal UI and benchmark runners, under the MIT license.

Hermes Agent (Nous Research)
Open-source agent harness; v0.21.7 stable shipped Oct 12, v0.22.0 RCs Oct 13-14.
IntentKit
Self-hosted cloud cluster for running a team of collaborating AI agents.
TrueForge
Open-source agent harness runtime that turns an LLM into a working agent.
Cayu
Cayu is an open-source Python framework for building and running domain-specific, long-horizon agents on a durable runtime. Sessions survive restarts and redeploys from SQLite or Postgres stores, tool policies can require human approval before side effects, spend caps are checked before each model call, and timers, background tasks, subagents and forks cover longer multi-agent work. It is Apache 2.0 licensed.
smolagents
Hugging Face's minimal library for code-writing agents.
DocETL
System for agentic, LLM-powered document processing and ETL pipelines from UC Berkeley.
