The Verdict
Insomnia is built for developers and api designers, with a focus on api-client and graphql-explorer. Postman targets developers and qa engineers and leads with api-testing and collections.
On pricing, Insomnia is the clear winner for budget-conscious users — starting at $5/mo compared to $14/mo for Postman. That $9/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Both tools are a solid fit for developers, api designers — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Postman has a slight overall edge — but if beautiful and intuitive desktop application matters most to you, Insomnia may still be the right call.
