Open WebUI alternatives: the open source options compared

What changes when the tool has to run the work

Open WebUI and Kortix are both open source, and the resemblance mostly stops there. A self-hosted chat interface gives a team a window over models and documents. Kortix, the open-source AI Operating System, gives a team somewhere to hand a job and a way to review what came back.

The split decides most alternative choices. Ask one question of anything on your shortlist: when the answer has to become a change in a real system, which machine runs it, and who approves it? A chat interface ends the turn at the reply. Kortix starts a session with its own isolated sandbox and its own branch, and the work reaches main through a change request a person reads first.

The repository is the second test. Agents, skills, company memory, connectors and triggers sit in one git repo you own, so a team can read a diff, roll a layer back, and carry the setup between environments. A chat deployment keeps its settings inside the application's own database.

A decision guide for an Open WebUI alternative

• You want a chat window over local and API models, self-hosted. Open WebUI covers that ground: it runs offline and connects Ollama and any OpenAI-compatible API (Open WebUI docs).
• You want those models plus agents that finish work and touch your tools. Kortix reaches 3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP, and each session runs on its own cloud computer.
• You want the setup in version control. Agents, skills, memory and connectors are files in a repo you own, and work reaches main through a change request.
• You want work to start with nobody watching. A trigger starts a session on a cron schedule or a signed webhook.

When the question is which interface, Open WebUI is a fair answer. When the question is where the work runs and who approves it, the shortlist changes, and that split is what this comparison weighs. To try it on your own repository, Try Kortix.
