Replacements
Listings that take over the same core job as ReqBin.
Hoppscotch
A fast API client that runs in a browser tab, with a self-hostable workspace if you want one.
Hoppscotch also runs in a browser tab without installing anything, is open source under MIT and self-hostable, and can reach local services through its extension or desktop app.
Restfox
A lightweight, offline-first open-source HTTP client that runs in the browser and on the desktop.
Restfox is an open-source, offline-first HTTP client usable in the browser without installing anything, keeping requests local rather than sending them through a third-party server.
Firecamp
An open-source API client for testing REST, GraphQL, WebSocket and Socket.IO requests in the browser.
Firecamp is open source and handles REST, GraphQL, WebSocket and Socket.IO in the browser with a guest mode, but saving requests requires an account.
Postman
The most widely used API client, for sending HTTP requests, organising them into collections and sharing them with a team.
Postman adds desktop apps, collections, scripts and a test runner alongside its browser version, but it is built around a cloud workspace that effectively requires an account.
RESTer
A browser extension for Firefox and Chrome for crafting and sending HTTP requests.
RESTer is a free browser extension for Firefox and Chrome that sends requests from your browser and keeps saved requests, rather than a website sending from its servers.
Scalar API Client
An open-source, OpenAPI-aware API client for sending and testing HTTP requests, from the Scalar API platform.
Scalar API Client is an open-source web client that understands OpenAPI descriptions, making it more useful when the API you test already has a specification.
Insomnia
An API client for REST, GraphQL and gRPC that can keep everything local or sync through Git instead of a cloud.
Insomnia is an open-source desktop client for REST, GraphQL and gRPC with test suites and mocking, requiring an install and usually an account instead of a quick browser visit.
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 desktop client that saves collections as files for Git and sends requests locally, so private endpoints are easier to reach than from ReqBin servers.
Also worth comparing
These listings name ReqBin as their own alternative, so the relationship runs both ways.
SoapUI Open Source
An open-source desktop tool for functional testing of SOAP and REST APIs.
ReqBin sends REST and SOAP requests from the browser with built-in response validators, but it offers no structured test suites and is not open source.
