# The open-source CrewAI alternative > CrewAI is a Python framework for building multi-agent apps, and it is open source. When the work grows past one application, a framework is only the build layer. Kortix is the open-source AI Operating System for that work: your agents, skills, memory and connectors in one git repo you own.

One git repo that is the company Agents, skills, memory, connector config and triggers are all text in one repo you own. `kortix.yaml` ```yaml # kortix.yaml agents: support-triage: file: agents/support-triage.md # what it does, in plain markdown connectors: all # what it may reach ``` Source: README.md in https://github.com/kortix-ai/suna ### 2. Every tool the company already runs on 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. `kortix.yaml` ```yaml connectors: - slug: gmail name: Gmail provider: composio app: gmail ``` Source: kortix.com/docs/connect/connectors ### 3. Run any model, keep your keys Any model provider with your own keys. Or the ChatGPT plan you already pay for. Or sign in with your OpenCode Console account for OpenCode Zen and Go. `terminal` ```sh $ kortix providers set ``` Source: kortix.com/docs/host ### 4. The part that turns a model into an agent OpenCode is the harness, configured by a file in the repo, so the layer doing the thinking is never the thing you are locked into. `kortix.yaml` ```yaml opencode: config_dir: harnesses/opencode ``` Source: kortix.com/docs/project/manifest ### 5. A computer per session One isolated sandbox per session. Each session has its own isolated machine and branch. `terminal` ```sh $ kortix sessions new --prompt "Reproduce issue #142, fix it, and open a change request" ``` Source: README.md in https://github.com/kortix-ai/suna ### 6. One gate to land the work Session work reaches main through a change request. Merge is default-deny for agents, so a person reads the diff first. `change-request flow` ``` change request ──> you review & merge ──> main ``` Source: README.md in https://github.com/kortix-ai/suna **20,000+** GitHub stars ## Open source.

Yes. CrewAI is an open-source Python framework with a large developer base, and its own site documents a commercial control plane around it. It is a strong choice when the deliverable is a Python application. Kortix answers a different question: running that work across a company as one system you own. ### Is CrewAI open source and free? CrewAI's framework is open source, and the repository is free to install and build on. CrewAI's own repository says the AMP Suite adds a commercial control plane around the framework for managed deployment, observability, governance and enterprise support, so the framework is free while the managed layer is commercial. ### What do teams use instead of CrewAI when the work is bigger than one application? Kortix, the open-source AI Operating System, is built for that. The same agents run in the web app, in Slack, in Microsoft Teams and from the CLI, on real cloud computers. The [framework or a whole system](/framework-or-system) page lays out the split. ### Can I own the whole system, not just the build layer? With Kortix, yes. Agents, skills, memory, connector config and triggers are files in one git repo you own, versioned and reviewable like code. You can run it on Kortix Cloud, in your VPC, or on your own on-prem network, and self-host is free. The [self-hosting guide](/self-hosting) covers the box. ### Does a person still review what an agent changes? Session work reaches main through a change request. Merge is default-deny for agents, and approval gates you set are off until you set them, so you decide what an agent may do on its own. ### What does Kortix cost? Free is $0 with 200 credits per month and 1 project. The team plan is $40 per seat per month with 2,500 credits per month per seat, pooled. Self-host is free. The full framework question is in the [Kortix vs CrewAI](https://kortix.com/blog/kortix-vs-crewai) write-up. ## Run your whole company from one repo you own. Start with one job, then grow it into the system your team runs on.
