An agentic analytics platform that turns questions into governed, trusted answers
Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.

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.

#1SpecialistOpen-source workflow automation built for AI agents and technical teams
SpecialistA free, open-source personal AI agent that learns your projects and works across every messaging app.
#3
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.
Faster for ad hoc statistical analysis and data visualization from natural language, but lacks Hex's robust notebook workflows.

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.
SpecialistOpen-source AI automation that unifies agents, flows and 770+ app integrations
Free / Open-sourceActs as a local server supporting multiple modalities, but requires separate frontend configuration for chat interactions.
