Open-source Eigent alternatives: the platform your team owns

Kortix is the open-source AI Operating System, the Eigent alternative that runs a whole team. The open-source field splits between local desktop Cowork apps and a platform a company owns, and the difference shows up in where agents run, which models they use and how work is reviewed.

FAQ

How to choose between Eigent and the open-source alternatives

Q.01

Which Eigent alternative fits a team rather than one person?

Kortix is built for teams. An account holds projects and people, permissions cover people and agents, and thousands of agents run in parallel on one config. The desktop Cowork apps are built around one machine and one person.

Q.02

Are all the open-source Eigent alternatives the same?

No. The field splits three ways: a local desktop Cowork app (Eigent, OpenWork and AionUi), a coding agent platform, and an AI Operating System a company owns. The real differences are where agents run and who holds the configuration.

Q.03

Can I self-host an open-source Eigent alternative?

Kortix self-hosts for free as one Docker Compose stack, and you run it on Kortix Cloud, in your VPC, or on your own on-prem network. Agent sessions run on a separate sandbox provider.

Q.04

How is Kortix different from a desktop Cowork app?

A desktop app runs agents on your machine and keeps the configuration on that machine. Kortix keeps every agent, skill and connector in a git repo you own, and runs each session on its own cloud computer with work landing through a change request.

Run your whole company from one repo you own.

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