About EchoAPI
EchoAPI is a tool for working with APIs through design, debugging, load testing, automation, documentation and mock servers. The developer says it needs no login, works offline and is compatible with Postman scripts, so existing Postman collections and test scripts can move across.
It comes as a desktop app, as plugins for VS Code and IntelliJ IDEA, as a command-line tool, and as a companion called EchoAPI Interceptor. Paid plans are offered next to the free app.

Alternatives to EchoAPI
Compare allSoftware that can replace EchoAPI for an important use case, and what changes if you switch.
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 client with collections, scripts, docs and mocks, adding desktop and browser apps, but an account is effectively required.
Apidog
An API platform for designing, debugging, mocking and testing APIs, with desktop and web clients.
Apidog is a closed-source platform for API design, debugging, mocking and testing with desktop and web clients, heavier than a simple request sender.
Apifox
An API platform for designing, debugging, mocking and testing APIs, with desktop and web clients.
Apifox covers design, debugging, mocking and testing in desktop and web clients, remains proprietary and freemium, and has limited public information on its features.
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 testing, mocking and an OpenAPI editor, though most of its features expect an account.
Testfully
An API client for building, testing, documenting and monitoring APIs, usable offline or with cloud storage.
Testfully offers offline local storage or cloud sync, imports from Postman and Insomnia, and adds monitoring, but it is proprietary with team features on paid plans.
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 keeping collections as plain files for Git, with a command line runner, and commits to never adding cloud sync.
Thunder Client
Lightweight REST and GraphQL client built into VS Code.
Thunder Client runs inside VS Code for REST and GraphQL with collections stored as repository files, without EchoAPI's load testing or mocking.
Requestly
An API client for designing and testing APIs, plus a browser HTTP interceptor for modifying requests.
Requestly stores collections as local JSON files, imports Postman collections in one click and adds a browser interceptor, but it is also closed source.
EchoAPI as an alternative

Newman
A command-line runner that executes Postman collections outside the Postman app.
EchoAPI runs Postman scripts and offers a CLI alongside its client, working offline without an account, though it is closed source with some paid features.
