LibreChat and Open WebUI are two self-hosted chat interfaces. Kortix is the open-source AI Operating System: agents, skills, memory and connectors in one git repo you own, with agents doing the work and a person approving each change. Here is how the three differ.
Two self-hosted chat interfaces side by side, plus the open-source system that runs the work.
A project is a git repo with kortix.yaml at its root.A session runs one agent in its own sandbox.The sandbox clones the repo and works on a new branch.The agent opens a change request against the project's default branch.A person with the project.gitops.merge permission reviews it and merges it.From the Kortix docs: each session runs on its own cloud computer and lands through review.
LibreChat is a self-hosted chat interface that gathers conversations across model providers into one customizable screen. Its own site lists agents with file handling, code interpretation and API actions, a side-by-side model comparison, and a quickstart that gets a server running in minutes (librechat.ai).
Open WebUI is a self-hosted AI platform that goes past plain chat. Its own documentation lists tools the model calls, MCP servers, scheduled automations, knowledge and retrieval, and shared Notes and Channels (openwebui.com). Both projects are open source and both connect to the same backends, so a team can host either one over Ollama, OpenAI, Anthropic or another provider. Open WebUI's own page on the pair sums it up as "different strengths, same ecosystem" (Open WebUI on LibreChat).
A chat interface answers prompts. It holds a conversation, compares two models on one question, and keeps the transcript. That covers a lot of personal and small-team use, and it is what LibreChat and Open WebUI do well.
The limit of a chat interface appears when work has to be decided, recorded and owned. A support queue, a report that goes to a client, or a change to production code needs more than a reply in a window. It needs a record of who approved what, a home for the team's own know-how, and a history a reviewer can read after the fact.
Kortix is the open-source AI Operating System. Your agents, skills, company memory and connectors live in one git repo you own, and the agents work on real cloud computers (Kortix docs).
A session runs one agent on its own cloud computer. The sandbox clones the repo and works on a new branch, so each session keeps its own working copy. When the agent finishes, it opens a change request, and a person reviews the diff before it reaches the default branch. Merge is default-deny for agents.
Governance lives in the same repo. Per-resource permissions for people and agents, roles, groups, and an audit trail ship with the project, so a reviewer can see what ran and what it touched. Approval gates you set. Off until you set them. Then a step that matters pauses for a decision.
Run Kortix on Kortix Cloud, in your VPC, or on your own on-prem network. Self-host is free. You bring any model provider with your own keys, so the models you already run behind LibreChat or Open WebUI keep working.
LibreChat and Open WebUI stay good chat clients. Kortix is a different layer, and it can sit beside either one.

The short answers the table and the guide do not settle.
No. LibreChat and Open WebUI are self-hosted chat fronts over the models you run. Kortix is the open-source AI Operating System: one repo that holds your agents, skills, memory and connectors, with each agent on its own cloud computer and work landing through a change request a person reviews. A chat client can stay beside it.
Yes. Run it on Kortix Cloud, in your VPC, or on your own on-prem network, and self-host is free. You keep the model and compute bills, and the configuration stays in your own repo.
No. Kortix works with any model provider with your own keys, so the providers you point LibreChat or Open WebUI at keep working. That covers local models behind Ollama and hosted APIs alike.
Yes. The two chat interfaces stay useful for everyday conversations, and Kortix is a separate layer for agents that finish work. Both reach the same model backends, so running them together adds no second set of keys.
Open source, on Kortix Cloud or self-hosted, with any model and your own keys.
