Definite

Definite is an all-in-one, AI-native data platform that consolidates data integration, warehouse storage, a semantic layer, BI dashboards, and AI agents into a single product. It ships 500+ managed data connectors, a DuckDB / DuckLake lakehouse, a Cube-based semantic layer, and Fi, a natural-language AI data analyst that builds complete data apps rather than just dashboards. Definite speaks the Model Context Protocol natively, exposing 40+ tools across six categories so Claude, Cursor, or any agent can query data, manage syncs, update semantic models, and build dashboards directly. The whole stack is self-hostable into a customer's own cloud account (BYOC) or on-prem, including the AI analyst, so data never leaves the environment. Its REST API supports stream ingestion into DuckLake, signed-URL file uploads, webhook-triggered Python pipelines, and embedding of Docs and data apps in external web apps.

Definite publishes 1 API on the APIs.io network. Tagged areas include Company, Data, Analytics, Business Intelligence, and Data Integration.

The Definite catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Definite’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, pricing, signup flow, and 24 more developer resources.
