Real Fake Data runs on your own machine — the client starts it, so there is no endpoint to ping. 43 installs a week from npm. Last commit 4 Jul 2026.
Realistic synthetic test data — valid PESELs, NIPs, IBANs, addresses, people across 27 EU countries.
Today is the operative word: we check Real Fake Data every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
REAL_FAKE_DATA_API_KEY (API key sent as `Authorization: Bearer <key>`, lifting requests onto your metered plan. Omit to use the anonymous lane.), REAL_FAKE_DATA_API_BASE_URL (Override the hosted API. Defaults to https://api.real-fake-data.com; point it at a local API during development.).
