Data Forge vs Mockaroo vs Faker.js — I Tested All 3 So You Don't Have To

If you've ever needed dummy data for testing, you know the pain.

You either:

  • Use Mockaroo (limited free tier, slow)
  • Write custom Faker.js scripts (takes time)
  • Or just hardcode 10 rows and cry 😭

I was building a project and needed 50,000 rows of realistic user data — fast.
So I tested the 3 most popular options. Here's what happened.


🥊 The Contenders

Tool Free Limit Export Formats Speed No Signup
Mockaroo 1,000 rows CSV, JSON, SQL Medium
Faker.js Unlimited Code only Fast
Data Forge (Zlvox) Unlimited CSV, JSON, SQL Instant

Mockaroo

The OG dummy data tool. Clean UI, lots of field types.

Problem?

  • Free plan caps at 1,000 rows
  • Need more? Pay up 💸
  • Requires account signup
  • Gets slow on large exports

Good tool — but in 2026, a paywall for basic data generation feels outdated.


Faker.js

Developer favorite. Powerful library, runs locally.

Problem?

  • You need to write code every time
  • Setup time for every new project
  • No visual UI — not great for non-devs on your team
  • No direct CSV/SQL export without extra setup

Perfect if you love terminal. Not great if you just need data right now.


Data Forge (Zlvox)

I built this because I was tired of both above options.

What it does:

  • Generate millions of rows instantly
  • Realistic data — names, emails, addresses, UUIDs, numbers
  • Export to CSV, JSON, SQL in one click
  • Zero signup. Zero paywall. Zero bloat.
  • Runs in browser — nothing to install

Real test: I generated 100,000 rows of user data in under 4 seconds.
Mockaroo timed out. Faker.js needed a custom script.


My Verdict

If you need data right now with no friction — Data Forge wins.

If you need programmatic generation inside your codebase — Faker.js.

If you love paying for things that should be free — Mockaroo. 😅
