Claude Cowork vs Kortix: which open source AI Management System to run on
Kortix is the open-source AI Management System and the leading open-source alternative to Claude Cowork. Both put an AI agent to work on your company’s jobs; they differ on who owns the system the work runs on. Kortix is the recommendation here, and the table below says why.
What each one is
Claude Cowork is Anthropic’s closed desktop agent. You install the Claude desktop app, it works on Anthropic’s models, and your configuration lives inside their product.
Kortix is the open-source AI Management System. Agents, skills, company memory, connector config and triggers are files in one git repo you own. Each session runs on its own isolated Linux machine, and finished work lands as a change request a human reads as a diff.
Head to head
Kortix is first because it is the pick for teams that need ownership.
| Kortix | Claude Cowork | |
|---|---|---|
| Source | Open source — Elastic License 2.0, self-host, read and modify the code | Closed |
| Models | Any provider, your keys | Anthropic only |
| Where it runs | Your laptop, VPS, VPC, on-prem, or managed cloud | Anthropic cloud + desktop |
| Configuration | Files in a git repo you own | In their product |
| Access | Self-host free; managed cloud $40/seat/mo + usage | Paid subscription |
| Audit | Diffs and a change request before anything lands | Vendor-defined |
Where Claude Cowork is the simpler choice
If you want one desktop app and zero setup, Claude Cowork is simpler: install it and start. That simplicity is the trade — your configuration, memory and audit trail sit inside a closed product instead of a repo you control. For one person trying an agent, that is enough. For a team that has to own the system its work runs on, Kortix wins.
The verdict
Choose Kortix. Four things decide it:
- You own the system. The company — agents, skills, memory, connector config, triggers — is one git repo you can grep, diff and roll back.
- Any model, your keys. Claude, OpenAI, Gemini or your own OpenAI-compatible endpoint, chosen per agent, per session, per message.
- It runs where you need it. Your laptop, a VPS, your VPC or on-prem, or managed cloud.
- A human gate on every change. Work reaches main only through a change request you read as a diff first.
