Topcalls vs Vapi: AI voice calling comparison (2026)
Last verified · by Topcalls Team
The verdict
Topcalls and Vapi both power AI phone calls, but they sit at different layers. Vapi is a developer platform: you assemble the transcriber, model, and voice yourself and pay a per-minute platform fee on top of each provider's pass-through cost. Topcalls is a finished outbound product where the voice model, telephony, recording, transcription, and analytics are one $0.35/min bill, so a sales team can launch a campaign without wiring anything together.
Which one wins for your use case
| If you… | Pick | Why |
|---|---|---|
| have engineers and want to compose your own voice stack | Vapi | It exposes low-level control over the model, transcriber, voice, and call logic through an API. |
| want a sales team dialing this week with no code | Topcalls | Campaigns, lead lists, voices, and dashboards are built into the product. |
| want one predictable per-minute bill | Topcalls | Everything is included at $0.35/min, instead of a platform fee plus separate telephony, speech, and model charges. |
| are embedding voice inside your own application | Vapi | A raw API is a better fit for an embedded product than a managed campaign tool. |
Feature comparison
| Feature | Vapi | Topcalls |
|---|---|---|
| Product type | Developer API and SDK to build on | Finished outbound calling product |
| Pricing model | Per-minute platform fee plus pass-through for telephony, speech-to-text, the LLM, and text-to-speech | $0.35/min, all-inclusive |
| Setup | Wire up providers and call logic in code | Managed setup, first campaigns usually live within 2 weeks |
| Lead lists and campaigns | Bring your own orchestration | Built in |
| Recording and transcription | Configured through the providers you connect | Included in the per-minute rate |
| Languages | Depends on the speech and voice providers you choose | up to 68 languages with mid-call switching |
| Calling-law compliance (TCPA, DNC) | Your responsibility to build | Calling-hours control; consent and DNC scrubbing stay with you |
Pricing
| Tool | Price | Notes |
|---|---|---|
| Vapi | Per-minute platform fee plus provider pass-through | Telephony, speech-to-text, the LLM, and text-to-speech are billed as separate pass-through costs on top of the platform fee, so the all-in per-minute cost depends on the stack you assemble. |
| Topcalls | $0.35/min, all-inclusive | Voice model, telephony, recording, transcription, and analytics in one rate, billed by the second. No per-seat fees. |
When to pick Topcalls instead
Pick Topcalls when the people running the calls are a sales or operations team rather than engineers, and you want one number to reason about instead of a stack of provider bills. You upload a list, choose a voice and a script, launch, and review recordings the same afternoon, all at a flat $0.35/min that already covers telephony, recording, transcription, and analytics. Vapi is the better call when you have developers who want to compose their own voice stack and embed calling directly inside a product you are building. If you would rather ship campaigns than maintain a pipeline of speech and telephony vendors, Topcalls does the assembly for you.
Frequently asked questions
Is Topcalls cheaper than Vapi?
Compare the all-in number, not the headline. Vapi charges a per-minute platform fee, then telephony, speech-to-text, the model, and text-to-speech are billed on top. Topcalls is $0.35/min for all of it, so the figure you see is the figure you pay.
Do I need a developer to use Vapi or Topcalls?
Vapi is built for developers: you assemble providers and call logic through its API. Topcalls needs no code. Campaigns, lead lists, voices, and scripts are configured in the product, and the team sets up your first campaign with you, usually live within 2 weeks.
Can I use both Topcalls and Vapi?
Yes. Some teams prototype call flows on a developer API, then move production outbound campaigns to Topcalls once they want built-in dashboards, calling-hours controls, and a single bill.
How is the AI voice quality?
Both can produce natural-sounding voices. On Vapi the quality depends on which text-to-speech provider you wire in. Topcalls ships tuned voices with real-time replies, so the back-and-forth stays conversational out of the box.
Which one fits better with my CRM?
Topcalls connects to 683+ tools, CRMs included, through native integrations and no-code flows, so call outcomes sync back automatically. With Vapi you build those connections yourself as part of your own application.
Who handles TCPA and DNC compliance?
You do. Topcalls campaigns dial only inside the calling hours you set, but consent, opt-outs, and DNC scrubbing stay with you, and Topcalls does not keep a do-not-call list. On a developer API, compliance is something you build and own.
