40+ Generators
Email, country, date, domain, emoji, product names, sentences, and more. Constraint support on integers and enums. Custom values via file generator.
What It Does
Any Output Format
Column-aligned, SQL INSERT, NDJSON, or full Go templates with helpers like Loop, Odd, and Even. Name your fields
with column=generator syntax.
Stream Mode
Continuous row generation for pipelines and load testing. Pipe to files, databases, queues, or APIs —
fakedata --stream email and never stop.
How It Works
1
Define
Pick your generators: fakedata email country. Add constraints like int:1,100 or custom
enums.
2
Format
Choose your output: default columns, --format=sql, --format=ndjson, or pass a Go
template for full control.
3
Pipe
Output to stdout, stream continuously, or pipe directly into your stack — databases, queues, APIs, anywhere.
