PayloadIQ is free for students

50+ JSON & API tools that run entirely in your browser — format, explore, explain, convert to TypeScript/Zod/Prisma/SQL, decode JWTs, diff responses, and craft AI prompts. No ads, no tracking, no signup. And students get double the daily allowance, free, in one click.

Unlock 100 actions/day — free

Everyone gets 50 actions/day free (plenty for coursework). Students get 100 — no email, no verification, no card. Just click.

On trust. No email, no verification, no card. Applies to this browser.

Why we make it free for students

Learning to work with APIs means staring at a lot of JSON. You shouldn’t have to dodge ads, paste your data into a sketchy site, or hit a paywall mid-assignment. PayloadIQ is built privacy-first — your data never leaves your browser — and we’d rather help you learn than gate the basics. If it saves you time on a project, that’s a win.

What you get, free

  • All the tools: format/validate, tree explorer, JSON→TypeScript/Zod/Prisma/SQL/YAML/CSV, JWT decoder, Base64, diff, mock data, and more.
  • Prompt Lab: turn a payload into a clean AI prompt locally — great for learning prompt engineering without leaking your data.
  • Private by design: everything runs in your browser. See how →
  • 100 actions/day once you click the button above (50 for everyone else).

FAQ

Is PayloadIQ really free for students?
Yes. The free plan already gives everyone 50 actions/day with no signup, ads, or tracking. Students can unlock 100/day in one click on this page — on trust, with no verification.
Do I need to prove I'm a student?
No. There's no email, no .edu check, no card. Click the button and it's unlocked on your browser. We'd rather trust you than make you jump through hoops.
What counts as an 'action'?
Switching to a tool (a tool session). Typing, formatting, and viewing results are never counted — and your JSON is never uploaded; every tool runs in your browser.
What can I use it for?
Debugging API responses, learning JSON, generating TypeScript/Zod/Prisma/SQL from a payload, decoding JWTs, diffing responses, and crafting AI prompts locally with Prompt Lab — all free.
