Point a layer at it. Get a form.

Introspect a PostGIS table or GeoPackage vector layer — labels, types, options, geometry, layout — render to live HTML. Pair with the offline field-collection PWA.

How it works

Schema-first, not hand-drawn

Introspect PostGIS or GPKG — 21 field types, 6 layouts, validation — then render to HTML / React / Vue / Angular / JSON Schema.

Two live sources

/generate/postgis and /generate/gpkg with schema preview before commit.

Field overrides

Swap widgets, defaults, help text, read-only — without touching the source table.

Geometry aware

Geometry columns map to a typed field for capture alongside attributes.

Offline PWA

Next.js + MapLibre + DuckDB-WASM — collect, edit, export GeoJSON/CSV/SHP/GPKG air-gapped.

Capability	Endpoint	Notes
Generate GPKG	`POST /api/dynamicform/generate/gpkg`	File + layer → typed form
Generate PostGIS	`POST /api/dynamicform/generate/postgis`	Connection + table
Render	`POST /api/dynamicform/{id}/render`	html + css + javascript
Standalone HTML	`GET /api/dynamicform/{id}/html`	Full page, themed
Templates	`GET /api/dynamicform/templates`	basic · grouped · complete
