An open-source long-horizon SuperAgent harness that researches, codes, and creates. With the help of sandboxes, memories, tools, skill, subagents and message gateway, it handles different levels of tasks that could take minutes to hours.
omo/lazycodex: The coding agent for tokenmaxxers;the one and only agent harness for complex codebases. For your Codex, for your OpenCode
🌊 The leading agent meta-harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory, self-learning intelligence, RAG integration, and native Claude Code / Codex / Hermes and many more Integrated
The batteries-included agent harness.
The first open-source harness builder for AI coding. Make AI coding deterministic and repeatable.
⌥ AI Coding agent for the terminal — hash-anchored edits, optimized tool harness, LSP, Python, browser, subagents, and more
Open-source, secure environment with real-world tools for enterprise-grade agents.
AI Agent Engineering Platform built on an Open Source TypeScript AI Agent Framework
Flexible and powerful framework for managing multiple AI agents and handling complex conversations
🧱 easy, fast and local-first microVM runtime
TypeScript AI agent orchestration framework with dynamic workflows. Describe the goal, not the graph: a coordinator plans the task DAG at runtime and runs it on any LLM (Claude, ChatGPT, Gemini, DeepSeek, or local models).
Your super agent for work: local-first, learn your working context in mins and never forget it.
ByteRover CLI (brv) - The portable memory layer for autonomous coding agents (formerly Cipher)
A lightweight, powerful framework for multi-agent workflows and voice agents
Cascading runtime for AI agents. Optimize cost, latency, quality, and policy decisions inside the agent loop.
Laminar - open-source observability platform purpose-built for AI agents. YC S24.
A coding agent and general agent harness for building and orchestrating agentic applications.
Open-source cross-agent memory layer for coding agents via MCP. Compatible with Claude Code, Codex, Cursor, Windsurf, Gemini CLI, Antigravity, OpenClaw, Hermes Agent, Oh-my-Pi, Pi, Copilot, Kiro, OpenCode, and Trae.
Secure runtime to sandbox AI agent tasks. Run untrusted code in isolated WebAssembly environments.
