Since Postman announced in May 2023 that it would be sunsetting Scratch Pad mode with its offline capabilities, teams that need to keep API workspace data off third-party servers have had to find alternatives. Insomnia is one such alternative: it's a free and open-source desktop application designed for API testing, development and debugging. Although Insomnia supports online syncing, it'll let you keep API workspace data offline. Our teams have found migration from Postman for manual API testing seamless as its features are similar, and it allows importing of Postman collections. Despite our teams' positive experiences with Insomnia, we're keeping an eye on other developing alternatives of various forms — from GUI tools like Insomnia that are drop-in alternatives, to CLI tools like HTTPie, to IDE plugins such as IntelliJ HTTP client plugin.
