dust

Dust lets a company build its own AI agents that plug into internal data and take action across the tools people already use: GitHub, Google Drive, Notion, Slack. Instead of buying a separate assistant for every department, you build agents once and route them across models like Claude, GPT, and Gemini. The platform is open source under MIT and you can run the whole thing yourself.

Self-hosting is a real project, not a weekend. This is a large TypeScript and Rust monorepo with multiple services, data connectors, and vector infrastructure to stand up, and you bring your own model API keys on top. You need a platform team that wants to own it. When that is not you, the hosted version exists for a reason.

Cloud Pro runs about 29 euros per user per month (roughly 31 dollars) and covers connectors, the better models, and SOC2 with zero data retention. Enterprise is custom, starts at 100 seats, and adds the things big companies cannot skip: SSO, SCIM provisioning, and data residency. Solo builders and small teams should just use the cloud. Large teams self-host only when owning the infrastructure beats the per-seat bill, which usually means real scale. It substitutes for the agent-building tiers of platforms like Glean or Microsoft Copilot Studio.

The catch: the MIT license covers the engine, but the value most teams actually pay for is the managed, connected, compliant version. Running it yourself means you own the connectors, the upgrades, and the 2am pages.
