The original
Apidog
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 Apidog.
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.
Apifox
An API platform for designing, debugging, mocking and testing APIs, with desktop and web clients.
Apifox offers the same combination of design, debugging, mocking and testing with desktop and web clients, is also proprietary and freemium, and has limited public feature details.
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, combines an OpenAPI editor, testing 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 is also closed source and covers debugging, load testing, mocking and documentation, but works offline without an account and runs Postman scripts.
Testfully
An API client for building, testing, documenting and monitoring APIs, usable offline or with cloud storage.
Testfully adds monitoring to building, testing and documenting APIs, lets you choose local offline storage or cloud sync, and imports from Postman and Insomnia, but stays proprietary.
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 an MIT-licensed offline client that keeps collections as plain files shared through Git, with a CLI runner, but it lacks built-in API design and mocking.
Yaak
An offline-first API client for REST, GraphQL, gRPC, WebSockets and SSE, with requests stored as files you can commit to git.
Yaak is an open-source offline-first client storing requests as files in git with no cloud account, but it focuses on sending requests rather than design and mocking.
Hoppscotch
A fast API client that runs in a browser tab, with a self-hostable workspace if you want one.
Hoppscotch is MIT-licensed and self-hostable, lighter and quicker to open, but offers fewer testing and mocking features than a full design platform.
Also worth comparing
These listings name Apidog as their own alternative, so the relationship runs both ways.
Mockoon
A desktop app and CLI for designing and running mock REST APIs locally without an account.
Apidog includes mocking within a closed-source platform for API design, debugging and testing, heavier than a dedicated mock tool.
RapidAPI for Mac
Native macOS HTTP client, formerly Paw, with code generation and team sync.
Apidog is a closed-source freemium platform combining API design, debugging, mocking and testing, available as desktop and web clients rather than a native macOS app.
Scalar API Client
An open-source, OpenAPI-aware API client for sending and testing HTTP requests, from the Scalar API platform.
Apidog combines API design, debugging, mocking and testing in desktop and web clients, but is closed source rather than open source on GitHub.
SoapUI Open Source
An open-source desktop tool for functional testing of SOAP and REST APIs.
Apidog is a closed-source freemium platform combining design, debugging, mocking and testing, available on web and desktop, rather than a free open-source desktop tool.
Stoplight
A web platform for designing OpenAPI descriptions, generating API documentation and running mock servers.
Apidog is also closed source and freemium, combining API design and mocking with debugging and testing, and offers a desktop client as well as the web version.
Swagger Editor
A browser-based editor for writing OpenAPI definitions and sending live requests to the API.
Apidog covers API design alongside debugging, mocking and testing in one freemium platform with desktop and web clients, but is closed source and heavier than an editor.
