Insomnium

Website: github.com/ArchGPT/insomnium

Insomnium, an Insomnia alternative

Insomnium is an open-source API client that was created by the community as an alternative to Insomnia. This happened when Insomnia started requiring users to create accounts and move their data to the cloud. Many users preferred to keep their work offline, so Insomnium was created as a fork of Insomnia’s last version before these changes and was developed as a version of Insomnia that stays fully offline without requiring any cloud services or accounts. It keeps all the features that made Insomnia popular but sticks to the original offline approach.

Insomnium vs Insomnia

  • API Support: Both Insomnia and Insomnium support RESTful, GraphQL, WebSocket, and gRPC APIs. This means you get the same flexibility in handling different API types with either tool.
  • Request Building: Insomnium offers the same request-building features as Insomnia, including support for various authorization methods. Since it’s based on an earlier version of Insomnia, it doesn’t have any new features but keeps the core functionalities intact, like building and sending API requests easily.
  • Environments & Folders: Like Insomnia, Insomnium supports global and environment variables but does not allow setting variables or authorization at the folder level. Both tools are similar in how they manage environments and organize requests.
  • Collaboration: Insomnium is a fully offline tool, so it doesn’t have cloud-based collaboration features. This is different from the current version of Insomnia, which has started moving towards cloud integration. If you’re working solo or in a small team that doesn’t need online collaboration, Insomnium keeps things simple and offline.
  • Deployment: Insomnium is available on Windows, Mac, and Linux, just like Insomnia. The main difference is that Insomnium is designed to work entirely offline, which makes it a good choice if you prefer to keep your work local without any connections to external servers.

Hoppscotch

  • Request Building: Hoppscotch offers a straightforward request-building interface that’s easy to use for basic testing. It includes support for query parameters, headers, payloads, and various types of authorization. Insomnia, on the other hand, offers a more robust set of tools, including a richer variety of authorization methods and more advanced configurations.
  • Environments & Folders: Like Insomnia, Hoppscotch allows you to use environment variables, which are useful for managing different testing environments. However, neither tool supports setting variables or authorization at the folder level. Insomnia provides slightly more advanced environment management features, but both are fairly limited in this area.
  • Collaboration: Hoppscotch, being a browser-based tool, offers some basic sharing features, but it’s less comprehensive than Insomnia’s options. Insomnia allows for basic collaboration through shared requests and environments, though neither tool is as team-focused as more advanced alternatives like Testfully.
  • Deployment: Hoppscotch is unique in that it’s entirely browser-based, meaning you don’t need to install anything to use it. This makes it very accessible and convenient for quick testing tasks. Insomnia is a desktop application available on Windows, Mac, and Linux, offering more features but requiring installation. Hoppscotch is working on a desktop application and has released its alpha version for Mac, Windows, and Linux.
