I was paying $70/month for Postman seats my team barely used. DevBook does what we actually need for a fraction of the cost. Took five minutes to get everyone set up.
This is a real DevBook template for the OpenAI API. Variables become fillable fields. Your API key auto-fills from the vault. Response appears below.
Per-seat pricing, bloated apps, and scattered credentials slow your team down. DevBook fixes all three.
Postman charges $14/user/month. A 10-person team pays $140/mo. DevBook Pro is $19/mo flat — add your whole team.
DevBook runs in the browser. No 300MB desktop app to install, no admin permissions needed, no version update cycles.
Stop sharing keys in Slack DMs and .env files. One encrypted vault, one source of truth. Keys auto-fill into templates.
Not a platform. A tool. Open a tab, build a request, get a response.
Mark dynamic parts with {{placeholders}} and DevBook turns them into input fields. Fill in the blanks, hit send. No raw JSON editing.
Store all your API keys in one secure place. DevBook matches key names to template variables automatically — your Stripe key fills every {{stripe_key}}.
Request on top, response on the bottom — syntax-highlighted, status color-coded, with timing in ms. Everything you need at a glance.
Templates and keys are shared across your team automatically. New devs are productive in minutes, not days. No collection imports or env file juggling.
Your developers need an API testing tool. You need it to be secure, affordable, and easy to roll out. DevBook is all three.

No collections, no environments, no workspaces. Just the parts you actually use.
Paste your keys into the vault. They're encrypted with AES-256-GCM and auto-fill into every template that uses them.
Define your HTTP request with {{placeholders}} for dynamic values. DevBook generates a clean fillable form.
Hit send, see your response instantly. Save the template so your whole team can reuse it — same request, same keys, no copy-pasting.
You're trusting DevBook with API keys and team data. Here's exactly how we handle them — no vague claims, just specifics.
Every API key stored in your vault is encrypted with AES-256-GCM — the same standard used by AWS, banks, and government systems. Keys are decrypted only at the moment of use and never stored in plaintext.
All connections between your browser and DevBook use TLS 1.2+. Your requests, responses, and credentials are never transmitted unencrypted. We enforce HTTPS on all endpoints.
We never log your request bodies or API responses on our servers. Your data passes through to execute the request and is not stored, analyzed, or accessible to DevBook staff.
When a team member leaves, remove them from your workspace. Their access to shared templates and the key vault is revoked immediately. You control who can see and use your credentials.
Getting your team set up takes minutes, not meetings. Here's the process:
You create a workspace and add your shared API keys to the vault. Only you control what keys are available.
Invite your team by sharing a link. Each member signs up with their own account — no shared credentials.
They start working immediately. Shared templates and vault keys are available from the first login. Nothing to configure.
Side-by-side on the things that actually affect your team and your budget.

I built DevBook because I got frustrated with how complicated and expensive API testing tools have become. I'm a self-taught developer — my background is actually in fire science and sociology. I wanted a simple tool that lets you open a browser tab, test an API, and get back to work. That's DevBook.
