How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Deepgram (Per Usage) — Deepgram bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Vapi (Per Usage) — Vapi bills purely on usage — PAYG. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

What each is best for
Deepgram is worth it if… developers building voice-first products that need low-latency speech APIs at scale. Nova-2 STT is the workhorse — best price/performance for real-time transcription.
Vapi is worth it if… developers who want maximum control over the voice stack — swap any STT, LLM, TTS, or telephony provider without vendor lock-in. 05/min is the lowest orchestration fee in the category, but the real cost is what you stack on top.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
