Kortix vs CrewAI: which open-source way to run a team of agents fits yours?

CrewAI is an open-source Python framework for orchestrating role-playing agents. Its own repository describes two primitives: Crews, for autonomous, role-based agent teams, and Flows, for event-driven workflows with precise control. Each agent carries a role, a goal, a backstory, tools and a model, and a task can define structured output and a human review step. It is the shape a Python team reaches for when it wants to compose multi-agent behaviour in code.

Kortix handles the layer where the agents run. Kortix is the open-source AI Operating System: your agents, their shared skills, your company memory and every connector live in one git repo you own, and each session runs on its own isolated cloud computer. Work lands through a change request a person approves. The source is on Kortix on GitHub.

With a framework, you own the code and you carry the operation. The runtime, the sandbox, the secrets, the scheduler and the review step are yours to stand up and keep running, and CrewAI's own commercial suite exists precisely because teams outgrow the bare framework: managed deployment, observability and governance come as a separate product.

Kortix moves that half of the work into the platform. A session boots its own isolated machine and branch, connector credentials are brokered server-side so raw keys never reach the agent, and the audit log records every action. Roles, groups and per-resource permissions apply to people and to agents, and approval gates are off until you set them. The configuration is text in a repo you own, so a teammate can read the history instead of trusting a black box.

Teams reach for a platform once the first crews have proved the idea and the questions change from how do we build this to who runs it, who approves it, and where the company's knowledge lives. The framework's flexibility is still there, but it is work you repeat for every agent, and the missing pieces are the shared ones: one place for memory, one review gate before work lands, and one set of permissions across the company.

CrewAI stays the better fit when a Python team wants to build the orchestration itself and keep every control flow in its own application. Kortix is the pick when you want the agents run, reviewed and governed for the whole company, with any model and your own keys.
