BYOK Call vs Vapi
Same voice-agent depth — without usage markup locking you into someone else’s rates. Bring your own keys, keep the bill transparent, and pay a flat platform fee.
No credit card · Flat platform fee · Your keys when you want them
Ownership and cost side by side
Same job — voice agents — different bill and control model.
| BYOK Call | Vapi | |
|---|---|---|
| Usage markup | $0 — providers bill you directly | Built into per-minute rates |
| Model / voice keys | Yours — swap OpenAI, Deepgram, ElevenLabs anytime | Platform-controlled or limited BYOK |
| Typical all-in rate | Providers ~$0.12/min + platform from $19/mo | ~$0.35/min illustrative managed class |
| Lock-in | Swap layers without rebuilding | Agent often tied to their stack |
| Who owns the bill | You see every provider invoice | Single opaque usage bill |
Illustrative comparison only. Vapi and other managed platforms publish their own plans; we use a ~$0.35/min all-in class rate so you can estimate total cost against BYOK Call (your keys + flat platform fee).

Questions
Is Vapi more expensive than BYOK Call?
At similar volumes, managed platforms in the ~$0.35/min class usually cost more all-in than running on your own keys plus our flat fee from $19/mo. Use the calculator on this page with your minutes — rates are illustrative and published plans vary.
Do I need my own API keys to start?
No. Start on managed credits, then connect your own keys when you want provider-rate usage and full ownership.
Can I migrate from Vapi?
Yes — rebuild the flow in our visual workflow builder, connect telephony and model keys, and publish. No platform markup on usage once you are on your keys.
Are these official competitor prices?
No. Competitor figures use an illustrative managed-platform class rate for comparison. Always check each vendor’s current published pricing.
