Store your keys once. Build request templates with fillable fields. Get answers in a clean split-screen interface. No $14/seat pricing. No download.
The popular API tools come with baggage. DevBook skips all of it.
Postman charges per seat, per month. Teams of 5 pay $70/mo for what should be a developer utility. DevBook is free — no seats, no tiers, no surprises.
Postman's Electron app ships 300MB+ and launches like it's loading an IDE. DevBook is a web app. Open a tab, start working. Close it when you're done.
Postman syncs your collections, keys, and environments to their servers. DevBook stores your API keys in your own account. Your requests stay yours.
