Why teams look beyond Onyx

The alternatives

01Open WebUI
Teams that mainly want a self-hosted chat interface over Ollama, OpenAI, Anthropic or any compatible API, with RAG and search built in. SSO, RBAC, audit logs and air-gapped deployment are part of its enterprise offer, through sales.
openwebui.com
02LibreChat
Teams that want an open-source chat interface across Anthropic, AWS, OpenAI, Azure and other providers, with agents, MCP tools and sign-in over OAuth, SAML or LDAP, installed locally or on a server.
librechat.ai
03AnythingLLM
Individuals who want document chat on their own computer with local models (an MIT-licensed desktop app), or small teams self-hosting a multi-user Docker deployment. The page lists no prices for its cloud option.
anythingllm.com
04Glean
Larger organisations that want a managed enterprise search, assistant and agents over 275+ connectors with permission-aware access, and are prepared to buy through a demo; no price is published.
glean.com
05Dust
Teams that would rather not run the stack themselves and want hosted agents over 70+ connectors with a choice of 20+ models. Self-serve Business covers teams up to 100 people; Pro is €24 per seat per month billed yearly.

06Fabric
Product and engineering teams that want to self-host under a single open-source licence: Fabric is Apache-2.0, free to use with your own model keys, and runs hosted at fabric.pro or self-hosted with Docker Compose or Aspire, the same code either way. It integrates with GitHub, Jira, Linear, Notion, Slack and Confluence and has 100+ integrations over MCP. Fabric is made by TechFabric, the publisher of this page.
