Answer in brief
Vapi and Bland AI are both programmable phone-agent platforms, built on opposite ideas. Vapi is an open stack. You pay $0.05/min for hosting, then pick your transcriber, model and one of 15 listed voice providers at cost, with no markup. Bland AI is a closed stack. One rate ($0.14/min on Start, $0.12/min on Build) covers the LLM, STT and TTS, Bland claims latency under 400 ms, and every plan carries a 99.9% uptime SLA. Pick Vapi to engineer every layer. Pick Bland to ship a production line on one number.
Top pick for production phone lines: Bland AI. One bundled rate, a 99.9% uptime SLA from the free Start plan up, and HIPAA with a signed BAA without a separate $2,000/month add-on.
Top pick for builders who want maximum control: Vapi.

What 1,000 minutes actually costs
Vapi's own estimate for 1,000 minutes on Vapi SIP is $82–$129/month: $50 hosting, about $10 transcription, $8–$45 model and $15–$24 voice. Add a success package or HIPAA if you need one. On Bland Start, 1,000 minutes is $140 plus telephony. On Build it's $299 + $120 = $419, which only makes sense once you need Build's 50 concurrent calls and 2,000 calls a day. Bland's FAQ argues that production Vapi stacks usually land at $0.13–$0.30/min once you choose premium models and Twilio. That's Bland's view. Vapi's calculator shows the lower end for its default picks. Price your real model and voice before deciding.
Voice quality and latency
Vapi's 15 providers (including ElevenLabs, Cartesia, Hume, Rime AI, Deepgram, OpenAI, Azure and Vapi Voices) let you match a voice to your brand and switch when a better one ships. Bland trades that choice for an integrated stack it says it owns end to end, and it claims latency under 400 ms. Both figures come from the vendors themselves, so place test calls under real network conditions.
Telephony and reliability
Vapi's status page tracks inbound and outbound service separately for SIP, Twilio, Telnyx and Vonage, which is useful for teams running several carriers. Bland connects to your existing Twilio account or any SIP trunk from a contact-center or telephony provider, and charges no transfer fees if you bring your own telephony. If an uptime commitment is a procurement requirement, Bland includes 99.9% on every plan. Vapi reaches 99.9% only on Premier.
When to pick which
- Pick Vapi if you're embedding voice into your own software, want WebRTC or WebSocket transport, or plan to tune the transcriber, model and voice independently.
- Pick Bland AI if you want one predictable rate, an uptime SLA from day one, on-prem/VPC deployment, or a compliance list that includes FedRAMP 20x Class A and ISO 27001.
