❤️ Lightweight: Crafted with minimalistic UI design.

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

🗄️ HTTP Methods: Request methods define the type of action you are requesting to be performed.

  • GET - Requests retrieve resource information
  • POST - The server creates a new entry in a database
  • PUT - Updates an existing resource
  • PATCH - Very similar to PUT but makes a partial update on a resource
  • DELETE - Deletes resource or related component
  • HEAD - Retrieve response headers identical to those of a GET request, but without the response body.
  • 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
  • <custom> - Some APIs use custom request methods such as LIST. Type in your custom methods.

  • Import cURL
  • Label requests

🔌 WebSocket: Establish full-duplex communication channels over a single TCP connection.

📡 Server-Sent Events: Receive a stream of updates from a server over an HTTP connection without resorting to polling.

🌩 Socket.IO: Send and Receive data with the SocketIO server.

🦟 MQTT: Subscribe and Publish to topics of an MQTT Broker.

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

  • Set endpoint and get schema
  • Multi-column docs
  • Set custom request headers
  • Query schema
  • Get query response

🔐 Authorization: Allows to identify the end-user.

  • None

History: Request entries are synced with your cloud/local session storage.

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

  • Unlimited collections, folders, and requests
  • Nested folders
  • Export and import as a file or GitHub gist

Collections are synced with your cloud/local session storage.

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

  • Set environment variables
  • Include timestamp in the request headers
  • Send a random alphanumeric string in the URL parameters
  • Any JavaScript functions

👨‍👩‍👧‍👦 Teams: Helps you collaborate across your teams to design, develop, and test APIs faster.

  • Create unlimited teams
  • Create unlimited shared collections
  • Create unlimited team members
  • Role-based access control
  • Cloud sync

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

  • Hide your IP address
  • Fixes CORS (Cross-Origin Resource Sharing) issues
  • Access APIs served in non-HTTPS (http://) endpoints
  • Use your Proxy URL

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

☁️ Auth + Sync: Sign in and sync your data in real-time across all your devices.

Sign in with:

  • GitHub
  • Google
  • Microsoft
  • Email
  • SSO (Single Sign-On)1

🔄 Synchronize your data: Handoff to continue tasks on your other devices.

  • Workspaces
  • History
  • Collections
  • Environments
  • Settings

Post-Request Tests: Write tests associated with a request that is executed after the request's response.

  • Check the status code as an integer
  • Filter response headers
  • Parse the response data
  • Set environment variables
  • Write JavaScript code

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

  • Unlimited environments and variables
  • Initialize through the 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

🚚 Bulk Edit: Edit key-value pairs in bulk.

  • Entries are separated by newline
  • Keys and values are separated by :
  • Prepend # to any row you want to add but keep disabled
