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.
- Regal AI (Per Usage) — Regal AI bills purely on usage — Custom. 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.
Enterprise-grade AI voice agent platform for contact centers. ~$0.20/min all-in based on aggregate data across millions of calls, plus platform and implementation costs. Enterprise-only sales motion — no self-serve tier. Third-party "$29/mo" claims are noise; ignore.
Voice AI agent platform for developers building conversational voice apps. Base orchestration at $0.05/minute PAYG (STT/LLM/TTS/telephony billed separately, ~$0.07–0.25/min all-in). 10 concurrent lines included; extra lines $10/mo each. HIPAA add-on $2K/mo, ZDR $1K/mo. Enterprise starts $40K–70K/year. Backed by Bessemer and Y Combinator. Direct competitor to Retell AI and Bland AI.

What each is best for
Regal AI is worth it if… contact-center teams processing high call volumes (hundreds of thousands to millions of calls/year) that need enterprise integrations, workforce management fit, and negotiated volume rates. Not the fit if transparent self-serve pricing is a must-have or if call volume is under 100K/year — Vapi or Retell AI ship faster and cost less at that scale.
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.
