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Good tool — but in 2026, a paywall for basic data generation feels outdated.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