Pure Go · Local-first · SQL without the ceremony

One SQL core.
Wherever your data runs.

tinySQL is a compact database engine for Go applications, browser-delivered tools, embedded systems and local data workflows — where heavyweight infrastructure does not fit.

Browser tools

Import local files, query them with SQL and export the result — without a backend.

Go and embedded

Keep storage and query logic close to the application with one compact, pure-Go core.

Local data work

Use joins, geodata, full-text and vector helpers only when the workflow needs them.

Supports: CSV, TSV, TXT, JSON, JSONL/NDJSON, YAML, XML, Excel, GeoJSON, TopoJSON, Shapefile (.zip), KML, OSM XML, routing graph
