Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.2
GPA, above 36 of the 101 other AI agents we grade
Vapi is an API-first platform for building voice agents that answer or place phone calls. It handles orchestration, telephony and monitoring, and lets you pick the transcriber, language model and voice provider. It is priced per minute of hosting plus provider costs.
To get you started, here are 9 things to know about Vapi, taken from its own pages and our grades.
No store rating, and the platform is built around API calls and provider settings.
- 1
Best for developers building voice agents on their own stack
Vapi is a developer platform for building voice agents on top of the providers you choose.
- 2
Paid plans start at $29 a month
As its pricing page puts it: $29 per month (Core); usage-only starts at $0.05 per minute hosting.
- 3
You can try it first
$5 in free credits to start; usage-only accounts then pre-pay for minutes.
- 4
It runs on Web
Web.
- 5
Voice agent orchestration
Configure voice, conversation flow, telephony and integrations for an agent, then deploy it behind a phone number or an API.
- 6
Choice of providers
The pricing calculator lets you pick the transcriber, language model and voice, for example Deepgram, OpenAI and ElevenLabs. Models are passed through at cost.
- 7
Testing and simulation
Calls can be simulated before they reach customers, and monitoring flags issues in live calls.
- 8
A 2.2 GPA, above 36 of 101
That is against the other AI agents we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace Vapi you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for developers building voice agents on their own stack
Vapi is a developer platform for building voice agents on top of the providers you choose. Hosting is $0.05 a minute plus model, voice and call charges, Core is $29 a month, and the next step up is $999 a month.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | C | Core is $29 a month and hosting is $0.05 a minute, but the page's own 1,000-minute estimate is $82 to $129 a month, and Pro starts at $999. |
| Free plan and trial | C | $5 in free credits to start. The page does not say whether a card is needed. |
| Features | B | Orchestration, a choice of providers, testing and simulation, and telephony options. The core job of a voice agent is covered. |
| Ease of use | D | No store rating, and the platform is built around API calls and provider settings. |
| Platforms and integrations | B | Web, with Twilio, Vonage, Telnyx, Deepgram, OpenAI, ElevenLabs and Daily listed. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Vapi is for
- Fits if you are a developer who wants to choose each voice and model provider
- Makes sense if you want to pay for minutes as you use them
Who it is not for
- Pricey if you want one price, as model, voice and call charges sit on top of the $0.05 hosting
- Watch out: HIPAA-eligible handling is a $2,000 a month add-on
- Pricey if you grow, since Pro has a $999 a month minimum
- Watch out: extra lines cost $10 each and extra organisations $20 each a month
Good to know
Good for
- Developers building phone agents for support, lead qualification or scheduling
- Teams that want to choose their own speech, model and voice providers
Worth knowing
- Without a success package, hosting is $0.05 per minute, pre-paid, and Deepgram, model and voice costs are added on top; the page's 1,000-minute estimate is $82 to $129 a month.
- HIPAA-eligible data handling is a $2,000 per month add-on.
- Extra concurrent lines cost $10 per line per month and extra organizations $20 per organization per month.
- Twilio, Vonage and Telnyx call charges are billed by those providers, such as $0.008 per minute for Twilio inbound.

Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace Vapi you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
It costs $348 a year.
What you could not
- An AI agent, with the models and the safeguards behind it.
- It plugs into other products, Twilio, Vonage and Telnyx among them, and has an API.
- What a company asks for before it lets staff use something: single sign-on, SOC 2 and HIPAA.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Vapi’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
