What are Testfully and Insomnia?
Testfully is a platform that helps developers test and monitor APIs during development and after deployment. You can use it to send requests to your APIs, create automated tests, and set up monitoring to catch problems before they affect users.
The tool comes in two versions: Cloud and Offline. The Cloud version stores your data online and makes collaboration easy. The Offline version keeps everything on your computer for enhanced privacy and security. Both versions have identical features, so you can choose based on your needs.
Testfully works with major API types including REST, GraphQL, and XML. It includes an API client for building requests, testing tools for validation, and monitoring features for tracking API health around the clock.
Insomnia is a desktop application that lets you test and work with APIs. Think of it as a specialized tool for developers who need to send requests to APIs and check the responses they get back. It supports all major API types, so you don't need different tools for different projects.
The tool includes helpful features like environment variables (which let you switch between different settings easily), code generation (which creates code snippets you can use), and authentication helpers (which handle login details). You can also create mock servers to test your APIs before they're fully built.
Insomnia offers both free and paid versions. The free version works great for most individual developers, while paid plans add team features and extra tools.
