stac-fastapi-pgstac
An implementation of STAC API based on the FastAPI framework and using the pgstac backend.
Decision gist · record as of 2026-08-14
Yes. The package is actively maintained, has low install friction, carries no known vulnerabilities, and is MIT-licensed. Install it if you need a production-ready STAC API server backed by PostgreSQL. Prerequisite: you must provision a PgSTAC database schema and have PostgreSQL with PostGIS available; the package itself is the HTTP layer, not a standalone database.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running PostgreSQL database with PgSTAC schema installed and pypgstac package available; Python >=3.11
- Low install friction with a pure-Python wheel.
- Active maintenance with a recent release 51 days ago and a commit history through August 2026.

What it is and what it does
stac-fastapi-pgstac is a FastAPI application that wraps PgSTAC, a PostgreSQL-backed STAC (SpatioTemporal Asset Catalog) database engine. It validates incoming HTTP requests against the STAC API specification, delegates search and retrieval operations to PgSTAC's procedural SQL functions, and enriches responses with standardized STAC links. The package stores all collection and item records as JSONB fields in PostgreSQL, preserving custom fields transparently.
The package is designed for deployments that need a standards-compliant HTTP interface to large geospatial metadata catalogs. It supports the STAC Sort Extension (with optimized datetime sorting), optional API-level or database-level result hydration, and the Multi-Tenant Catalogs Extension for hierarchical catalog structures with directed acyclic graph support. Runtime dependencies include asyncpg for async database access, pydantic for validation, and orjson for fast JSON serialization.
Use it for
- Expose a searchable STAC API endpoint over HTTP for a PostgreSQL-backed geospatial metadata catalog
- Build a multi-tenant geospatial data platform with hierarchical catalogs and poly-hierarchy link navigation
- Integrate STAC search into a larger FastAPI application using stac-fastapi-pgstac as a backend module
- Serve large spatiotemporal asset collections with optimized datetime-based sorting and filtering
- Deploy a STAC API with custom JSON fields preserved transparently through JSONB storage
