Kivel vs Hoppscotch
Hoppscotch organizes reusable API requests into collections. Kivel supplies disposable resources and utility operations for integration testing. They can work together: send a request from Hoppscotch to a Kivel mock or receiver.
Why teams pick Kivel.
Choose Kivel when you need a destination for a callback, a temporary mock response, a test file or an operation an agent can discover. Resources expose explicit lifetimes and public/private access. The same hosted operations are reachable through ordinary HTTP, the SDK, CLI and MCP.
- You need an externally reachable test receiver
- You need short-lived mocks or file shares
- You want utility results from the same API as your test resources
Choose Hoppscotch when the main job is maintaining and reusing an API request collection. Its documentation covers nested collections, sharing, and import/export with Hoppscotch, OpenAPI and Postman formats. That is a different job from creating a temporary receiving endpoint.
- You repeatedly send a related set of requests
- You need collection organization and sharing
- Your workflow uses collection import and export
Every Kivel plan includes webhook and email inboxes, mock APIs and MCP servers, files, memory, monitors and approvals for AI agents over one MCP connection, plus 174 tools in all. Free to start; Pro is $2 a month.
The differences that matter.
| Area | Kivel | Hoppscotch |
|---|---|---|
| Starting point | Create a resource, run a utility or repeat a small API scenario. | Organize and reuse requests in collections and sub-collections. |
| Running checks | Up to six sequential requests on one public origin, with variables, secret headers, JSON captures and response checks. Browser saves and JSON exports exclude secret values. | A collection runner with configurable delays, iterations and environment variables. |
| Portability | Export and import supported mock configurations as JSON; use the published API contract and client examples. | Collection import/export includes Hoppscotch, OpenAPI and Postman formats. |
| Receiving callbacks | A webhook inbox captures method, path, headers, query and body, with searchable history. | Use your API client to send requests to a receiver such as a Kivel inbox. |
| Using them together | Create a mock or inbox; copy its endpoint and provide a separate access header when private. | Keep the request in a collection and reuse it while changing the destination or test body. |
Good to know.
Kivel has a bounded scenario runner for up to six sequential requests on one origin, with variables, checks and non-secret JSON captures. It does not import Postman collections, run scripts or provide a full collaborative collection platform. Its scenario JSON and mock configuration exports are separate formats. Hosted runs and temporary resources use plan allowances, so a temporary mock is not a permanent production API.
You can start without an account, and a free account keeps resources for up to seven days. See the published allowances for storage, rate limits and retention.
Frequently asked questions
Can I use Hoppscotch with Kivel?
Yes. Create an available mock or inbox in Kivel, then use its endpoint in Hoppscotch. Private endpoints require the separate sender access header; do not put access tokens in the URL.
Can Kivel import a Postman collection?
Not currently. Supported mock JSON configuration import is a different format. Hoppscotch documents collection import/export for Postman and OpenAPI.
Is a request client the same as a webhook receiver?
No. A request client sends an outgoing HTTP request. A receiver provides an endpoint another system can call, then stores the captured request for inspection.
