Open Source AI Agent Framework
SpecificationOpen sourceRev 2026-10-14
For engineers choosing how to run their agents

Build agents with an open-source AI agent framework. Run them on Kortix.

An open-source AI agent framework gives your team a library to build agents. Kortix is the open-source AI Operating System that runs them: agents, skills, memory and connectors in one git repo you own, each session on its own cloud computer, and every change approved by a person before it lands.

The open-source AI Operating System

Each session has its own isolated machine and branch.

A framework builds agents. Kortix runs them.

LangGraph, CrewAI and AutoGen are libraries your engineers compose into an application; Kortix is the open-source system that runs and governs the agents a company depends on.

What the operating system does for you

Six jobs a framework leaves to your team, each handled in one place you own.

  1. Build

    One repo for the whole company

    Agents, skills, memory and connectors are files in one git repo you own, and kortix init scaffolds it.

    $ kortix ship

  2. Host

    A cloud computer per session

    Run it on Kortix Cloud, in your VPC, or on your own on-prem network from one stack.

    Exhibitterminal
    $ kortix self-host start

  3. Manage

    Changes a person approves

    Session work reaches main through a change request a person reviews and merges.

    Exhibitterminal
    $ kortix cr merge 1
    Source: https://kortix.com/docs/quickstart
  4. Monitor

    Every action recorded

    The audit log records every action, and roles and grants decide who reaches what.

  5. Train

    Memory that compounds

    Your company memory is files in the repo, so every session starts from what the company already knows.

    Exhibitkortix.yaml
    Agents, skills, memory, tools, triggers and connectors are files in it.

  6. Eval

    Check the setup before you trust it

    kortix doctor checks the login and the project, then pings a throwaway session before you rely on it.

    $ kortix doctor

Questions engineers ask about open-source AI agent frameworks

What is an open-source AI agent framework?

It is a library your engineers import to build agents, and LangGraph, CrewAI and AutoGen are examples. A framework defines how agents reason, call tools and hand work to each other, while your team still builds and operates the runtime around it.

Is Kortix a framework or a platform?

Kortix is the open-source AI Operating System, so it is a platform rather than a library. Agents, skills, memory and connectors live in one git repo you own, and every session runs on its own cloud computer.

Can I self-host Kortix?

Yes. Run it on Kortix Cloud, in your own VPC, or on your own on-prem network; self-hosting installs the full platform with the kortix self-host commands, and self-host is free.

Which models can the agents use?

Any model provider with your own keys, or the ChatGPT plan you already pay for.

How does Kortix compare with LangGraph and CrewAI?

LangGraph and CrewAI are frameworks you build with; Kortix is the system that runs and governs the agents. Kortix vs LangGraph and Kortix vs CrewAI each cover one head to head.

Run your agents on the system you own
