The Verdict
Firebase is built for mobile developers and startups, with a focus on firestore and authentication. Heroku targets startups and prototyping and leads with git-deploy and managed-postgres.
On pricing, Firebase is the clear winner for budget-conscious users — starting at $0/mo compared to $5/mo for Heroku. That $5/mo difference adds up quickly for growing teams.
Firebase has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Heroku requires a paid subscription from day one.
Firebase edges out on user ratings (4.4 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Both tools are a solid fit for startups, small teams — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
Bottom line: Firebase has a slight overall edge — but if simplest deployment experience (git push to deploy) matters most to you, Heroku may still be the right call.
