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.

Why teams switch

The tools you have are costing you more than money

Per-seat pricing, bloated apps, and scattered credentials slow your team down. DevBook fixes all three.

💸

Stop paying per seat

Postman charges $14/user/month. A 10-person team pays $140/mo. DevBook Pro is $19/mo flat — add your whole team.

📊 For managers: predictable cost that doesn't grow with headcount.
📦

No install, no IT tickets

DevBook runs in the browser. No 300MB desktop app to install, no admin permissions needed, no version update cycles.

📊 For managers: zero deployment overhead. Link your team a URL.
🔑

API keys in one vault

Stop sharing keys in Slack DMs and .env files. One encrypted vault, one source of truth. Keys auto-fill into templates.

📊 For managers: centralized credential management with audit-ready encryption.
Features

Built for how developers actually work

Not a platform. A tool. Open a tab, build a request, get a response.

{}

Template builder with fillable fields

Mark dynamic parts with {{placeholders}} and DevBook turns them into input fields. Fill in the blanks, hit send. No raw JSON editing.

#

Encrypted API key vault

Store all your API keys in one secure place. DevBook matches key names to template variables automatically — your Stripe key fills every {{stripe_key}}.

/

Split-screen response viewer

Request on top, response on the bottom — syntax-highlighted, status color-coded, with timing in ms. Everything you need at a glance.

👥

Shared team workspace

Templates and keys are shared across your team automatically. New devs are productive in minutes, not days. No collection imports or env file juggling.

Why your team should use DevBook

Your developers need an API testing tool. You need it to be secure, affordable, and easy to roll out. DevBook is all three.

  • 💰
    Flat pricing that scales $19/mo whether you have 3 developers or 30. No surprise invoices when you hire.
  • 🔐
    Credentials stay controlled API keys are encrypted with AES-256-GCM and stored in a shared vault. No more keys in Slack, email, or random .env files.
  • 5-minute team onboarding Send your team a link. They sign up, access shared templates and keys instantly. No downloads, no IT involvement.
  • 📋
    Standardized workflows Shared templates mean every developer uses the same API calls. Less duplication, fewer mistakes, better consistency.

How it works

Three steps. Zero setup.

No collections, no environments, no workspaces. Just the parts you actually use.

01

Add your API keys

Paste your keys into the vault. They're encrypted with AES-256-GCM and auto-fill into every template that uses them.

02

Build a template

Define your HTTP request with {{placeholders}} for dynamic values. DevBook generates a clean fillable form.

03

Send and share

Hit send, see your response instantly. Save the template so your whole team can reuse it — same request, same keys, no copy-pasting.

Security & compliance

How we protect your credentials

You're trusting DevBook with API keys and team data. Here's exactly how we handle them — no vague claims, just specifics.

🔐

AES-256-GCM encryption at rest

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.

🔒

TLS encryption in transit

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.

🚫

No payload logging

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.

👥

Team access controls

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.

🚀

Team onboarding — how it actually works

Getting your team set up takes minutes, not meetings. Here's the process:

Step 1

You create a workspace and add your shared API keys to the vault. Only you control what keys are available.

Step 2

Invite your team by sharing a link. Each member signs up with their own account — no shared credentials.

Step 3

They start working immediately. Shared templates and vault keys are available from the first login. Nothing to configure.

Hey, I'm Kristie 👋

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.
