SupaFill

Inspiration

I used FakeFiller and other tools, but they filled forms with random, inconsistent data. You'd get "John" as first name, "Smith" as last name, but "alice@example.com" as email. It looked fake and broke testing scenarios that needed realistic data.

What it does

SupaFill generates a complete persona per form:

• First name: Sandrine
• Last name: Thomas
• Email: sandrine.thomas10@yopmail.com
• Username: sandrinethomas534

Everything matches! This makes your test data look realistic and helps catch bugs that only appear with proper data relationships.

How we built it

After typing "test@test.com" thousands of times and dealing with inconsistent random data from other tools, I wanted something that:

1. Generated realistic, consistent data
2. Worked with modern frameworks
3. Respected privacy (100% local)
4. Had a personality (hence the NeoBrutalism design)

Accomplishments that we're proud of

• PRIVACY FIRST 100% offline - All data generated locally, no external APIs No tracking - Zero analytics, zero data collection No account required - Works immediately after install

• LIGHTWEIGHT Under 80KB total. No bloat, no dependencies, just fast form filling.

What's next for SupaFill

• More locales (planning 20+ total)
• Team sharing for custom field rules
• AI-powered field detection improvements
