Agent frameworks

An AI agent building platform with out-of-the-box data processing and model-calling capabilities, letting users assemble complex question-answering applications through a visual workflow editor.

• Agent frameworks
• RAG

An open-source, opinionated agent harness built on LangGraph, with sub-agents, a pluggable filesystem, persistent memory, human-in-the-loop approval and loadable skills bundled in by default.

• Agent frameworks

An SDK and CLI that gives AI agents access to more than 1,000 pre-authenticated toolkits across external apps, with per-user sessions, authentication, triggers and a sandbox for turning an agent's intent into action.

• Agent frameworks
• MCP servers

A lightweight, container-isolated alternative to OpenClaw: an AI assistant that runs each agent in its own Linux container and connects to Slack, Telegram, Discord, WhatsApp and other messaging apps.

• Agent frameworks

A production-ready agent framework built around a ReAct reasoning-and-acting loop, a pluggable toolkit and model layer, and composable middleware, designed to work with increasingly capable models rather than constrain them with rigid orchestration.

• Agent frameworks

A self-hosted personal AI agent runtime, distributed as a single Rust binary, that connects to about twenty LLM providers and reaches the user through more than 30 channels such as Discord, Telegram, email and a custom CLI.

• Agent frameworks

A multi-agent orchestration platform that lets a user define agents, workflows and tasks through configuration rather than code, evolved from an earlier system that simulated a whole virtual software company.

• Agent frameworks

A self-hosted personal AI assistant that runs locally or in the cloud, reachable from many chat platforms at once, with layered memory, a plugin and skill marketplace, and sandboxed tool execution.

• Agent frameworks

A frontend SDK for building agent-native applications: generative UI, shared state, and human-in-the-loop workflows for React, Angular, Vue and React Native, plus Slack and Microsoft Teams.

• Agent frameworks
• Web frameworks

A framework for programming language models with compositional Python code instead of hand-written prompts, with algorithms that optimize the prompts and weights of the resulting pipeline.

• Agent frameworks

An open-source multimodal AI agent stack combining Agent TARS, a general-purpose GUI and vision agent driven from a CLI or web UI, with UI-TARS Desktop, a native desktop application built on the UI-TARS model.

• Agent frameworks

A multi-agent orchestration layer for Claude Code that adds an autopilot command and configurable workflow stages so a task is planned, built and checked by coordinated agents rather than a single session.

• Coding agents
• Agent frameworks

An open-source agent workspace for research, content and software development that lets teams choose among model providers and open-source agent harnesses.

• Agent frameworks

A local-first, Rust-based agent harness with one core that runs as a desktop app, browser UI, terminal client and library, connecting to whichever LLM, memory or search engine a user already runs.

• Agent frameworks

An open-source agent chatbot platform that connects large language models to messaging apps such as QQ, WeChat Work, Feishu, DingTalk, Telegram and Slack, with plugins, a web UI and a code execution sandbox.

• Agent frameworks

A low-level orchestration framework for building long-running, stateful agents, with durable execution that resumes after failures, human-in-the-loop control, and short- and long-term memory.

• Agent frameworks

A framework and runtime for building agent platforms: an SDK to build agents, a runtime to serve them as a service, and a web UI to manage and observe them.

• Agent frameworks

CowAgent is an open-source, self-hosted "agent harness" that plans tasks, runs tools and skills, and improves itself over time through memory and a growing personal knowledge base, reachable across the web and major chat platforms.

• Agent frameworks

nanobot is an ultra-lightweight, self-hosted personal AI agent framework in Python that runs in a browser WebUI, a terminal, or chat apps, combining tools, long-term memory, MCP and multi-agent delegation in a small core.

• Agent frameworks

LlamaIndex is an open-source Python framework for building agentic applications, developed alongside LlamaParse, the company's own platform for agentic document parsing, extraction and indexing.

• Agent frameworks
• RAG

Goose is a general-purpose, open-source AI agent that runs on a user's own machine as a desktop app, CLI or API, for coding, research, writing, automation and data analysis tasks.

• Agent frameworks

PrivateGPT is an open-source API layer that turns a locally running, OpenAI-compatible model server into a full private-AI application backend, modeled on the Claude API's shape.

• Agent frameworks
• Inference

OpenManus is an open-source agent framework, built as a free alternative to the invite-only Manus agent, that gives a single agent web browsing, code execution and tool use from a plain-language goal.

• Agent frameworks

CrewAI is a Python framework for production multi-agent workflows, offering role-based autonomous agent "Crews" alongside precise, event-driven "Flows" that mix single LLM calls with agent collaboration.
