Features

How it works

Dekart is a self-hosted single Docker application, built with Golang and React. It connects to your data warehouse and exposes MCP, enabling agents to create maps and improve accuracy on geospatial tasks.

Documentation

Dekart is a single Docker container that can be deployed to any cloud provider or on-premises server. By default it uses built-in SQLite for metadata and local file storage, so it can run with zero configuration. For production deployments, you can configure S3/GCS backups or a Postgres metadata backend.
