The original
Apifox
An API platform for designing, debugging, mocking and testing APIs, with desktop and web clients.
Replacements
Listings that take over the same core job as Apifox.
Apidog
An API platform for designing, debugging, mocking and testing APIs, with desktop and web clients.
Apidog covers the same design, debugging, mocking and testing workflow with desktop and web clients, also freemium and closed source, with more feature detail published.
Postman
The most widely used API client, for sending HTTP requests, organising them into collections and sharing them with a team.
Postman is the most widely used API client with collections, scripts, documentation and mock servers, but it is closed source and built around a cloud workspace needing an account.
Insomnia
An API client for REST, GraphQL and gRPC that can keep everything local or sync through Git instead of a cloud.
Insomnia is open source under Apache-2.0 with an OpenAPI editor, test suites and mocking, and can keep data local or sync through Git instead of a cloud.
EchoAPI
An API client for designing, debugging, load testing and documenting APIs, compatible with Postman scripts.
EchoAPI covers debugging, load testing, mocking and documentation, runs Postman scripts, and works offline without logging in, though it is also closed source with paid features.
Testfully
An API client for building, testing, documenting and monitoring APIs, usable offline or with cloud storage.
Testfully offers building, testing, documenting and monitoring APIs with a choice of offline local storage or cloud sync, and imports from Postman and Insomnia, but is proprietary.
Requestly
An API client for designing and testing APIs, plus a browser HTTP interceptor for modifying requests.
Requestly stores collections as local JSON files that work with Git, adds a browser interceptor for rewriting requests, and supports GraphQL, SOAP and gRPC.
Bruno
An API client that saves collections as plain files in a folder, so Git handles the sharing instead of a cloud account.
Bruno is open source under MIT and keeps collections as plain files shared through Git, offline only, but lacks the built-in design and mocking features of Apifox.
Hoppscotch
A fast API client that runs in a browser tab, with a self-hostable workspace if you want one.
Hoppscotch is open source under MIT, runs in a browser tab or can be self-hosted, but has fewer testing and mocking features than full API platforms.
Also worth comparing
These listings name Apifox as their own alternative, so the relationship runs both ways.
Swagger Editor
A browser-based editor for writing OpenAPI definitions and sending live requests to the API.
Apifox bundles API design with debugging, mocking and testing in desktop and web clients, as a proprietary freemium product broader than a spec editor.
