Hex

Hex is an AI-powered analytics platform that combines agentic notebooks, interactive data apps, and conversational self-serve analytics so teams can go from ad-hoc exploration to published, governed data apps. The Hex External API (bearer-token authenticated, base https://app.hex.tech/api/v1) lets you programmatically run and schedule projects, manage projects, collections, groups, cells, and data connections, ingest semantic models, drive AI agent Threads (create, continue, read messages), export projects, and administer workspace users. Hex also ships a first-party CLI, a hosted remote MCP server, Airflow and Dagster integrations, and published Claude Agent Skills. Surfaced as an a16z portfolio company and enriched with its real public developer surface.

Hex publishes 11 APIs on the APIs.io network, including Cells API, Collections API, Context API, and 8 more. Tagged areas include Company, Analytics, Data Science, Notebooks, and Business Intelligence.

Hex’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, changelog, and 26 more developer resources.
