Fake data generator — tools.voiddo/fakeit vs generatedata.com
Both tools generate fake test data. fakeit is seedable, schema-driven, and runs entirely in your browser. generatedata.com has more field types and multi-format export — with server processing.
tools.voiddo/fakeit
- Seedable — same seed always produces identical output
- Schema-driven — define fields in JSON, reuse across runs
- Browser-only — no data sent to any server
- Names, emails, phones, addresses, ISBNs, credit cards (Luhn-valid), IBAN, dates, lorem ipsum
- MIT licensed, zero telemetry
- Works offline after initial load
generatedata.com
- No seed control — output is always random
- Visual row-builder UI (no portable schema file)
- Server-side generation — schema and output transmitted
- More field types: currency, weighted lists, autoincrement, custom regex
- Multi-format export: JSON, CSV, SQL INSERT, Excel, XML
- Requires active internet connection per generation

FAQ
What makes fakeit different from generatedata.com?
fakeit is seedable and schema-driven — you define your data structure in JSON and pass a numeric seed for reproducible output. generatedata.com uses a visual row-builder with no seed control and no portable schema file. fakeit also runs entirely in your browser; generatedata.com processes your schema on its server.
What is a seed and why does reproducibility matter?
A seed is a fixed starting number for the random generator. With the same seed, fakeit always produces exactly the same data — same names, same emails, same phone numbers. This is critical for reproducible tests, regression suites, and shared QA environments where everyone must see identical fixture data.
Does fakeit send generated data to a server?
No. All generation runs in your browser using JavaScript — no schema, no seed, and no output is transmitted anywhere. If you are generating data that resembles real customer or employee records, this matters.
Can I define a reusable schema for my project?
Yes. fakeit accepts a JSON schema file describing your fields and types. Save it to your repo and call fakeit with that schema whenever you need fresh fixture data — same structure, configurable seed and count.
When would I still use generatedata.com?
generatedata.com supports more field types (currency, weighted distributions, custom regex, autoincrement) and can export to SQL INSERT, Excel, and XML. If your project needs those specific formats or field types, generatedata.com is the better tool. For seedable, reproducible, browser-private data, fakeit is the stronger choice.
Is fakeit free and open source?
Yes. fakeit is MIT licensed with zero telemetry. No account, no ads, no data collection.
