Alfera vs Kortix
Kortix: Open-source AI Operating System: agents, skills, memory and connectors in one git repo; each session runs on its own cloud computer. Alfera is the AI coworker your whole team shares: a company brain that syncs your apps, connections shared per person or per team, permissions on every action, and Slack, WhatsApp and email. Open source, in one click on your server or on Alfera Cloud.
In one line: Alfera is one coworker shared by a team, vs an AI agent platform you assemble.

Where Kortix (formerly Suna) is the better choice
Teams wanting an open-source, self-hosted alternative to Claude Cowork or ChatGPT Work, with agent config kept as code in git.
- Company configuration (agents, skills, memory, connectors, triggers) lives as files in a git repo, versioned and reviewed like code
- Agent output reaches main only through a change request a person reviews, with a preview per change request
- Runs in Microsoft Teams as well as Slack, and has a full CLI (kortix init / kortix ship)
Everything Alfera does
- A company brain that syncs your apps. Connect Google Drive, Notion, Slack and the rest. Documents sync on their own, keep every version, and every answer draws on them.
- One coworker for the whole team. It knows who is asking. Many people, many tasks at once, each with their own chats and connections, and shared chats when you want.
- 3,000+ app connections, shared the way you choose. Each connection is open to everyone, one project, or one person. A personal mailbox stays personal; the support inbox is the team’s.
- Permissions on every action. Allow, ask first, or never, per connection and per action. Approvals land in Slack, email or the app, and every action is logged.
- Where your team already is. Slack, WhatsApp, email from its own address, the web app, a Mac app, and your own code through the API and MCP.
- It starts work by itself. On a schedule, from a webhook, or on 600+ app events in Gmail, HubSpot, Stripe and more.
- Its own computer. Every chat runs in a sandbox with a terminal and a browser, and its files stay from one chat to the next.
- Any model. 230+ models: Claude, GPT, Gemini, open models, your ChatGPT plan, or a model you run yourself.
- Open source, and free to start. AGPL-3.0. Self-host it in one click on DigitalOcean or AWS, or start on Alfera Cloud with $10 of free AI usage.
