Start in Landing Layer — upload source files to begin
Autosave ready at Waiting for autosave. Every Bronze, Silver, and query change is persisted locally.Cmd/Ctrl+K palette · Cmd/Ctrl+Enter run query · Cmd/Ctrl+Shift+E send to editor
Landing Layer — Raw IngestionUpload raw source files (CSV, JSON, Parquet) or fetch from a REST API. Data lands as-is — no transformations applied here.
Ingest Source Data
Upload CSV, JSON, or Parquet. Each file becomes one raw source table in the Landing Layer. No transformation is applied — the original shape is preserved.
Supported: .csv, .json, .parquet · Max 10 MB / 10 files files (Free)
Landed Tables
No data landed yet. Upload files or fetch an API to populate the Landing Layer.

Candidate joins
Review inferred Silver joins, accept the valid paths, and preview any join directly in the SQL editor.
Add more related tables and lock primary keys to surface inferred joins here.

Data Lab

Build the model before
the editor ever opens

Stage source data, profile shape and quality, validate joins in DuckDB, and hand off a cleaner modeling starter instead of a raw import dump.

Gold Preview
No mart candidate yet
Define the Silver layer and accepted joins first. Gold builds the medallion model from your curated Silver schema, not the raw Bronze upload.
Send the current Bronze/Silver workflow into the editor as either a normalized 3NF starter or a Raw -> Staging handoff.

Upload multiple related tables and curate Silver primary keys to unlock candidate relationship suggestions.
Query Workbench
Validate grain, joins, and metrics
Run full-data DuckDB checks against the staged tables, then promote trusted results into the schema flow.
Guided Checks
Load tables and accept relationships to unlock ready-made checks for duplicates, null rates, orphan keys, and join previews.
