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.
Build resilient agents.
Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 20% fewer tokens for coding agents, 60-95% fewer tokens for JSON, same answers. Library, proxy, MCP server.
The agent engineering platform.
The Open Standard for Generative UI
Python tool for converting files and office documents to Markdown.
The batteries-included agent harness.
[MLsys2026 Best Paper]: https://arxiv.org/abs/2506.08276. RAG on Everything with LEANN. Enjoy 97% storage savings while running a fast, accurate, and 100% private RAG application on your personal device.
agent runtime security - zero trust, zero setup, zero latency.
Unbounded context. Memory that manages itself. One session, for life. The hippocampus for coding agents, part of CortexKit.
The AI-Native Search Database. Best for agent storage, it unifies vector, text, structured, and semi-structured data into a single engine. This all-in-one database makes agents smarter, easier to run, and more stable.

Agentic Chain (AGNT): a chain for agents, built on BNB Smart Chain. Entry needs an ERC-8004 identity. Genesis carries three system contracts and three neutral tools (Multicall3, a CREATE2 deployer, Wrapped AGNT); every token, pool and market beyond that is deployed by an agent. Pre-launch.
