Live Demo
## Quick Start ```sh docker run -p 8080:8080 dekartxyz/dekart ``` [Deployment Options](https://dekart.xyz/docs/self-hosting/docker/?ref=github) ### Optional: install Claude/Codex skill ```sh pip install geosql && geosql ``` Then ask Claude or Codex to build a map from your data. ## Map Examples [BigQuery](https://dekart.xyz/docs/about/overture-maps-examples/) | [Snowflake](https://dekart.xyz/docs/about/snowflake-kepler-gl-examples/) | [Wherobots](https://dekart.xyz/docs/usage/wherobots-sql-tutorial/) ## Features * Connect to Postgres, BigQuery, Snowflake, Wherobots, DuckDB and more * Create live maps dashboards with SQL or Claude and Codex agents * Multiple layers, H3, interactive charts, query parameters * WebGL maps, responsive at 1M points * Share private maps with links * SSO: Google OAuth, Keycloak, AWS Cognito, Google IAP ## 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. * [Quick Start](https://dekart.xyz/docs/self-hosting/docker/?ref=github) * [Environment Variables](https://dekart.xyz/docs/configuration/environment-variables/) ### Deployment Guides: - [Run with Docker](https://dekart.xyz/docs/self-hosting/docker/?ref=github) - [Run with Docker Compose profiles](https://dekart.xyz/docs/self-hosting/docker-compose/?ref=github) - [Keycloak + Postgres reverse proxy example](https://dekart.xyz/docs/self-hosting/keycloak-reverse-proxy/?ref=github) - [Docker Compose examples by setup](install/docker-compose/README.md) - [Deploy to AWS/ECS (Terraform)](https://dekart.xyz/docs/self-hosting/aws-ecs-terraform/?ref=github) - [Deploy to Google App Engine](https://dekart.xyz/docs/self-hosting/app-engine/?ref=github) - [Enable SSO for self-hosted instance](https://dekart.xyz/docs/self-hosting/enable-sso-open-source-instance/?ref=github) ⭐️ Press GitHub Star to get notified of updates. ## Support [Slack Community](https://slack.dekart.xyz) ## License This project is open source under the GNU Affero General Public License Version 3 (AGPLv3) or any later version.
