Flatten nested objects to dot-path keys and back.

Convert values between string, number, boolean, and date.

Run @rfjs/data-filter conditions against sample data live.

Decode a JWT's header and payload, with a live expiry status.

Generate PostgreSQL JSONB queries from filter metadata.

Generate MongoDB queries from filter metadata.

Visually build an in-memory filter over sample JSON and see matching rows live.

Visually build a PostgreSQL JSONB WHERE clause over sample JSON and see the compiled SQL live.

Visually build a boolean filter over sample JSON and see it compiled to parameterized SQL over plain columns.

Visually build a boolean filter over sample JSON and see it compiled to a MongoDB query object live.

Visually build a boolean filter over sample JSON and see it compiled live to an Elasticsearch / OpenSearch bool query (valid for both).

Build a filter, compile it to an Elasticsearch / OpenSearch search body, and run it with the real @rfjs/es-client over a mock transport that truly filters the sample data (search · paginate · highlight).

Visually build one filter tree that mixes plain SQL columns and JSONB paths, and see the unified PostgreSQL WHERE clause live.

A 2D form builder — drag fields on a 12-column grid, group them, set per-field config, and preview live.

Render read-only BPMN 2.0 process diagrams from XML — pick a sample, paste XML, or upload a .bpmn file, then zoom and fit.

Visually wire a no-code flow — drag form / condition / action nodes onto a canvas, edit each node with the embedded builders, and see the flow JSON live. (Phase 1: edit only, no execution.)

DMN-style decision table — rules are nested filter trees, outputs are constants or expressions; evaluate one context or a whole batch live.

Interactive object transformation playground.

Config-driven data table — derive column config from a data resource's metadata, edit it, and preview offset/page/cursor pagination live.

Author a data resource's metadata — field kinds, enum domains, and the request/response protocol — then hand it to any consumer as meta.json.
