Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
AI governance, testing, and observability for regulated enterprises
Dozens of pre-built evaluations cover quality, safety, security, and performance, with LLM-as-a-judge scorers, session-level metrics, and support for writing your own custom tests against your own data.
Import a repository and run evaluation suites automatically on every change, benchmark each iteration, and block releases when a metric regresses beyond the threshold you define.
Trace every request through multi-step agent workflows, including tool calls and retriever steps, with token counts, latency, cost per request, alerting integrations, and subpopulation analysis.
Register each AI system with an owner, purpose, data sensitivity, and risk tier, score inherent risk across multiple dimensions, and move systems through staged approval gates before they reach production.

SpecialistOpen-source personal AI assistant that runs on your own machine and works from chat apps

SpecialistSpecializes in visual workflow building and RAG pipelines rather than serving purely as a chat interface.

Free / Open-sourceFocuses on collaborative team AI workspaces and plugins, but shares similar open-source architectural goals.
SpecialistFocuses heavily on privacy-first document chat and local RAG pipelines, but offers fewer general-purpose chat UI features.

Free / Open-sourceOffers robust multi-provider support and advanced user permission management, but has a slightly different configuration setup.
Free / Open-sourceDelivers a desktop-native application for running local models offline easily, but lacks Open WebUI's server-centric multi-user features.
