❤️ Lightweight: Crafted with minimalistic UI design.

⚡️ Fast: Send requests and get/copy responses in real-time.

HTTP Methods
  • GET - Requests retrieve resource information
  • HEAD - Retrieve response headers identical to those of a GET request, but without the response body.
  • POST - The server creates a new entry in a database
  • PUT - Updates an existing resource
  • DELETE - Deletes resource or related component
  • CONNECT - Establishes a tunnel to the server identified by the target resource
  • OPTIONS - Describe the communication options for the target resource
  • TRACE - Performs a message loop-back test along the path to the target resource
  • PATCH - Very similar to PUT but makes a partial update on a resource
  • <custom> - Some APIs use custom request methods such as LIST. Type in your custom methods.

🔮 GraphQL: GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data.

  • Set endpoint and get schemas
  • Multi-column docs

  • Query schema
  • Get query response

🔐 Authentication: Allows to identify the end user.

  • None

⏰ History: Request entries are synced with cloud / local session storage to restore with a single click.

📁 Collections: Keep your API requests organized with collections and folders. Reuse them with a single click.

  • Unlimited collections, folders and requests
  • Nested folders
  • Export as / import from GitHub gist

Collections are synced with cloud / local session storage

🌐 Proxy: Enable Proxy Mode from Settings to access blocked APIs.

Official proxy server is hosted by Hoppscotch - GitHub - Privacy Policy

📜 Pre-Request Scripts β: Snippets of code associated with a request that are executed before the request is sent.

  • Initialize environment variables
  • Include timestamp in the request headers
  • Send a random alphanumeric string in the URL parameters

📄 API Documentation: Create and share dynamic API documentation easily, quickly.

  1. Add your requests to Collections and Folders
  2. Export Collections and easily share your APIs with the rest of your team
  3. Import Collections and Generate Documentation on-the-go

⌨️ Keyboard Shortcuts: Optimized for efficiency.

Shortcuts WIki

ğŸŒŽ i18n: Experience the app in your own language.

  1. Scroll down to the footer
  2. Click "Choose Language" icon button
  3. Select your language from the menu

Keep in mind: Translations aren't available for all source and target language combinations

📦 Add-ons: Official add-ons for hoppscotch.

Add-ons are developed and maintained under Official Hoppscotch Organization.

☁️ Auth + Sync: Sign in and sync in real-time.

Sign in with

  • Google
  • GitHub


  • History
  • Collections
  • Environments
  • Notes

✅ Post-Request Tests β: Write tests associated with a request that are executed after the request response.

  • Check the status code as an integer
  • Filter response headers
  • Parse the response data

📝 Notes : Instantly jot down notes, tasks or whatever you feel like as they come to your mind.

Notes are only available for signed-in users

🌱 Environments : Environment variables allow you to store and reuse values in your requests and scripts.

  • Unlimited environments and variables
  • Initialize through pre-request script
  • Export as / import from GitHub gist

  • By storing a value in a variable, you can reference it throughout your request section
  • If you need to update the value, you only have to change it in one place
  • Using variables increases your ability to work efficiently and minimizes the likelihood of error
