Generates synthetic datasets from distributions you choose — every value traceable to a real, visible parameter, never a hidden model. Runs entirely on this machine: no account, no server, no telemetry.
- Broad, deep synthetic data — a large registered type catalog spanning numeric, temporal, identifiers, categorical, geo, text, images, speech, and declared causal structure.
- Eight export formats: CSV, TSV, Parquet, SQLite, JSON, JSONL, SQL, and Excel.
- Scenario Mode drafts a recipe from a plain-language description, with an offline template tier that needs no setup at all.
- Every export ships a data dictionary and a provenance record naming exactly how it was made.
First launch on macOS
SenSym Data Factory's .dmg is unsigned and not notarized by Apple — deliberately (durable
decision 1: no code-signing, no Apple Developer Program membership, no paid gatekeeping between
this project and the people who want to run it). That means macOS's own Gatekeeper will refuse
to open it on the first try, with a message like "Apple could not verify 'SenSym Data
Factory' is free of malware." This is expected, not a sign anything is wrong with the
download — a from-source build with pnpm package:mac produces the identical, equally
unsigned result.
To open it anyway#
- Drag SenSym Data Factory.app from the mounted
.dmginto Applications. - Right-click (or Control-click) the app in Applications and choose Open from the menu — not a plain double-click. This shows a dialog with an Open button that a plain double-click's blocked-launch dialog does not.
- If step 2's dialog only offers Cancel (recent macOS versions sometimes only show this the first time): open System Settings → Privacy & Security, scroll down to the security notice naming this app, and click Open Anyway. Confirm once more in the dialog that follows.
After this one-time approval, the app opens normally — with a plain double-click — from then on.
Command-line alternative#
Clearing the quarantine attribute the download added has the same effect and skips the dialogs entirely:
xattr -cr "/Applications/SenSym Data Factory.app"
Why this is safe to do here#
Gatekeeper's warning exists to catch software tampered with in transit or from an unknown
publisher — it is not a statement that this specific app is unsafe, only that Apple has not
been paid to vouch for it. Verify the .dmg's checksum against the one published alongside the
release if you want independent confirmation the download itself was not altered.
