Insomnia alternatives
12 other tools do this job. Which one is right depends on why Insomnia is not working for you — so start from the reason, not the list.
Why teams leave Insomnia
- A forced-account change in 2023 damaged trust; check the current model before standardising on it.
- Test scripting is less capable than Postman's.
- Smaller ecosystem of shared collections.
Worth saying: Insomnia is genuinely strong at this — noticeably faster and lighter than postman for everyday request work. If that is the part you rely on, switching may cost more than it saves.
If cost is the problem
Cheaper than Insomnia at the entry point, or free outright.
