HEAVY.AI

HEAVY.AI is a GPU-accelerated analytics platform (formerly OmniSci / MapD, now part of NVIDIA) built to interactively query and visualize very large, often geospatial and time-series, datasets. It pairs an open-source, GPU-accelerated SQL database (HeavyDB) with a server-side rendering engine (HeavyRender) and a web-based visual analytics application (Heavy Immerse). Developers interact with the platform through native SQL, an Apache Thrift API, JDBC/ODBC drivers, the heavysql command-line console, a Python data-science client (heavyai) and a JavaScript connector (@heavyai/connector), plus a Vega-based rendering API. The documentation is published on the NVIDIA docs site and exposes an llms.txt index and a hosted MCP server for AI agents.

HEAVY.AI publishes 1 API on the APIs.io network. Tagged areas include Company, Ai, Analytics, Database, and GPU.

HEAVY.AI’s developer surface includes documentation, API reference, getting-started guide, changelog, CLI, authentication, and 11 more developer resources.
