Kortix

What is Kortix?

Kortix (also known as Suna) is an open source AI agent platform that lets teams build and run a workforce of autonomous AI agents. You give an agent a task in plain language and it browses the web, runs commands, calls APIs, and produces files — each session running in its own isolated cloud sandbox. Agents, skills, and memories are stored as versioned files you control.

What is Kortix best for?

Teams and developers who want a self-hostable, model-agnostic home for AI agents instead of a closed vendor platform. It fits companies that need agents shared across Slack, the web, and the CLI, want to bring their own LLM keys, and prefer to keep agent runs and data on their own infrastructure.

What can Kortix do?

• Run generalist agents that browse the web, extract data, execute shell commands, and generate documents
• Orchestrate specialist agents that work in parallel on assigned tasks
• Give each session an isolated cloud sandbox so agent work stays contained
• Connect to 3,000+ apps plus MCP, OpenAPI, GraphQL, and generic HTTP integrations
• Encode reusable, shareable skills and memories that persist across sessions
• Trigger runs on a schedule (cron) or via webhooks, and reach users through Slack, email, and voice
• Work with any LLM using your own API keys — no single-model lock-in

Where does Kortix fall short?

• It’s source-available, not OSI open source. Kortix is licensed under the Elastic License 2.0: free to self-host and modify, but you can’t offer Kortix itself as a competing hosted service.
• Agent quality tracks the model you plug in. Kortix supplies the orchestration and tools, but reliability on complex, multi-step tasks depends on the LLM (and your API budget) you bring.
• Naming and positioning have shifted quickly — the project started as “Suna,” a generalist Manus alternative, and now markets as an enterprise “AI command center,” so docs and community guides can lag the current build.

Is Kortix free?

Yes — Kortix is free to self-host under the Elastic License 2.0, and you only pay for your server plus your own LLM API usage. Kortix also offers a managed cloud at roughly $40 per seat/month plus usage, so you’re paying for hosting and convenience, not the software itself.

What does Kortix replace?

Kortix is an open source alternative to closed agent products like Manus and Devin, and a self-hostable stand-in for doing agentic work in ChatGPT. It does the same autonomous-task job — research, browsing, coding, document generation — but you run it on your own infrastructure with your own models.

FAQ

Is Kortix open source? Not by the strict OSI definition — it’s source-available under the Elastic License 2.0. The code is public and free to self-host and modify, but you can’t resell it as a hosted service.

Can I self-host Kortix for free? Yes. Self-hosting is free; you deploy it with Docker Compose (kortix self-host start) on a laptop, VPS, or on-prem network. You pay only for the server and the LLM API keys you supply.

Is Kortix a good Manus alternative? For teams that want control, yes — it’s model-agnostic, self-hostable, and free to run, where Manus is closed and credit-based. The tradeoff is you handle setup and bring your own model keys.

What do I need to run Kortix? Docker (it deploys via Docker Compose) and an API key for at least one LLM provider. It runs on a laptop, VPS, VPC, or on-premises network.
