How it works

Three steps. Zero learning curve.

No collections. No environments. No workspaces. Just the parts of API testing you actually use.

01

Add your API keys

Paste all your keys in one secure vault. Stripe, OpenAI, Twilio, whatever you use. Reference them across every template with a single variable.

02

Build a template

Define your HTTP request and mark the dynamic parts with {{placeholders}}. ReqPad turns each one into a fillable text field. No raw JSON editing.

03

Run and reuse

Fill in the blanks, hit send, see your response instantly. Every template is saved and indexed so you can find it in seconds next time.

Why ReqPad

Built for how you actually work

Every API tool wants to be a platform. ReqPad wants to be a tool.

{}

Template-first design

Start from the request you want to make. Mark dynamic parts with curly braces. ReqPad generates the input form for you automatically.

#

One key vault

Store all your API keys in a single, secure vault. No more copying keys between tabs or hunting through .env files.

/

Split-screen results

Build your request on top, see the response on the bottom. Formatted, syntax-highlighted, and instant. No page switching.

i

Searchable index

Every template you save is indexed and searchable. Find the exact request you need in seconds, not minutes of scrolling through collections.

The notepad for APIs.

Not another platform. Not another lifecycle tool. Just a fast, focused workbench where developers go to call APIs and get answers.
