The Verdict
Firebase is built for mobile developers and startups, with a focus on firestore and authentication. Postman targets developers and qa engineers and leads with api-testing and collections.
On pricing, Firebase is the clear winner for budget-conscious users — starting at $0/mo compared to $14/mo for Postman. That $14/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.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
