A Go agent harness and service framework

Open-source, self-hosted Claude Code - a terminal AI assistant and the Python framework behind it. Tool-calling, sandboxed execution, multi-agent teams, skills, checkpoints, unlimited context - on Pydantic AI, any model.

A Go framework for building production agent systems with graph workflows, tools, memory, A2A, AG-UI, MCP, evaluation, and observability.

The open-source memory and observability layer for AI agents — persistent memory, loop detection, hash-chained audit trails, and a live dashboard, automatic on pip install.

The Rust SDK for building coding agents. Tools, streaming, graph, sub-agent orchestration, MCP — as composable functions

Real time communication for agents. Wake on message, channels, DMs and actions. Useful for orchestrating agents.

Deterministic safety solutions for probabilistic AI agents

The open-source TypeScript framework for building AI workflows and agents. Designed for Claude Code describe what you want, Claude builds it, with all the best practices already in place.

OpenJudge: A Unified Framework for Holistic Evaluation and Quality Rewards

AI said it finished. Flyto2 shows the proof.

Smithers is an agentic workflow framework for defining workflows in simple TypeScript configuration files and executing them quickly, durably, and reliably

Allows you to emulate an Android native library, and an experimental iOS emulation

Multi-language agent runtime and library for execution scope management, lifecycle events, and middleware on tool and LLM calls.

Open-World Self-Evolution for LLM Agents — agents that build both their skills and their own verification signals from scratch, with no target-task supervision. (Code coming soon.)

Semi-Structured Agentic Framework. Workflows build themselves as agents discover what needs to be done, not what you predicted upfront.

MCP Server Framework and Tool Development library for building custom capabilities into agents.

OpenBrowser is a framework for intelligent browser automation. It combines direct CDP communication with a CodeAgent architecture, where the LLM writes Python code executed in a persistent namespace, to navigate, interact with, and extract information from web pages autonomously.

Control 1 or more machines using computer use tools that integrates with your agents

Vercel AI SDK community provider for Claude Agent SDK

C# coding-agent harness (.NET 10, Microsoft Agent Framework) — sessions, tools, permissions, providers, MCP, plugins

A minimal yet powerful framework for creating AI agents with full control over tools, providers, and execution flow.

TypeScript-first framework for the Model Context Protocol (MCP). You write clean, typed code; FrontMCP handles the protocol, transport, DI, session/auth, and execution flow.

Composable agent runtime with enforced isolation boundaries

🌋 Build AI agents that seamlessly combine LLM reasoning with real-world actions via MCP tools — in just a few lines of TypeScript.
