The Verdict
Deepgram is built for developers and contact centers, with a focus on speech-to-text and text-to-speech. Firebase targets mobile developers and startups and leads with firestore and authentication.
Both tools come in at similar price points ($0.0036/mo for Deepgram, $0/mo for Firebase), so pricing won't make the decision for you.
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.
