About this category
Tests, demos, mock APIs, seed scripts, screenshots — they all need believable values. Real data is expensive, sensitive, and slow to produce, so most teams reach for a generator dozens of times a day.
These tools give you those generators in one consistent place. Get a UUID, a batch of random IDs, a numeric range, a string with the right alphabet, or a complete JSON document of fake records — copy-ready, with the option to fix a seed for reproducibility.
What you can do here
-
UUIDs and structured IDs
Generate UUIDs, random strings, numeric IDs, timestamped IDs, and custom prefixed or suffixed IDs for app schemas.
-
Random numbers with control
Generate ranges, distributions, and batches with explicit bounds, decimal places, and seedable output for reproducible tests.
-
Strings with character classes
Generate slugs, tokens, codes, and passwords with chosen alphabets, lengths, and exclusion rules (no ambiguous characters, etc).
-
Structured JSON fake data
Produce realistic seed data — users, addresses, orders, posts — as JSON arrays you can drop into a fixtures file or a mock endpoint.
