Self-host an open-source Eigent alternative

Kortix is open source, and self-host is free, so the whole platform runs on a Linux box you control. Eigent runs a Cowork desktop app on your machine. Three commands start it, and each session runs on a separate sandbox provider.

The layers

Six layers you run yourself.

Kortix is open source, and every layer here is a file or a command you can read.

  1. 01Repo

    One git repo that is the company

    Your agents, their skills, your company memory, and every connector live in one git repo you own.

  2. 02Connectors

    Reach into the tools you already run

    3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP. Connector credentials are brokered server-side and never enter the machine.

FAQ

Self-hosting questions, answered

Q.01

What is the open-source Eigent alternative?

Kortix is the open-source AI Operating System you can run yourself. Your agents, skills, company memory, and connectors live in one git repo you own, and self-host is free.

Q.02

Is self-hosting really free?

Yes. Self-host is free. The stack needs the internet: kortix self-host start pulls images from docker.io, and the instance must be reachable so the sandbox can call back.

Q.03

Where do agent sessions run when I self-host?

Sessions run on a separate sandbox provider, not on the stack you host. The default is Daytona; Platinum and E2B are also supported.

Q.04

Do I need a domain?

For production, point an A/AAAA record at the box and open ports 80 and 443, then run kortix self-host init --domain kortix.example.com and kortix self-host start. To evaluate without a domain, kortix self-host init --tunnel cloudflare uses a Cloudflare tunnel; the tunnel URL changes on every restart.

Run your whole company from one repo you own.

Start free, self-host, or run it on Kortix Cloud.
