Hoppscotch

Project80.6K

What you can build

  • Code a small generator that takes endpoint, expected-status, and required-field rows and outputs JavaScript post-request test snippets for Hoppscotch.
  • Build a local tool that takes two downloaded JSON responses and outputs added, removed, or changed paths and value types without altering either file.
  • Create a text transformer that accepts pasted cURL commands, replaces credential values with placeholders, and outputs sanitized commands for review or import.
  • Build a converter that accepts a generated request snippet, replaces configured secret patterns with named placeholders, and outputs a fenced Markdown example.
  • Write a checker that compares environment key-value text with Hoppscotch bulk-edit entries and outputs missing and extra keys plus a proposed bulk-edit list.

Try this prompt

Build a local JSON response diff tool for files downloaded from Hoppscotch. Accept two file paths, parse both as JSON, and report added, removed, or changed object paths and value types. Preserve both inputs; never upload data or make network requests. Show clear errors for unreadable files and invalid JSON. Include tests for nested objects, arrays, missing keys, and unchanged values. Do not assume an undocumented Hoppscotch export format.

Get started

  1. Choose a client

    Open the web app or use the official desktop-app documentation for Windows, Linux, or macOS.

  2. Send a request

    Enter an API endpoint, choose a method, send the request, and inspect the response.

  3. Develop or self-host

    For development or a private deployment, follow the official self-hosting getting-started documentation.

License & notes

MITThe MIT license permits commercial use subject to its notice requirements. Self-hosting requires compute, storage, networking, and operations; hosted options may have separate terms or costs. Calls to third-party APIs may incur their own charges. The supplied documentation identifies no model dependency and provides no pricing; no dollar amounts or plan limits are asserted.

  • Hoppscotch documents sending requests and proxy mode, not general capture and interception of application traffic.
  • Self-hosting requires infrastructure and operations; the supplied evidence does not specify resource requirements or pricing.
  • Request scripts, imported requests, and generated snippets may need review and adjustment for the target API and local conventions.
