SolarDialer vs Vapi
Vapi is a developer platform for building voice AI agents. SolarDialer is built on Vapi: it is a ready-to-run dialer that reactivates your old leads, with the scripts, campaigns, compliance checks and transfers already built.
SolarDialer suits
Sales teams that want old leads called this week, without building or maintaining a voice agent, a dialer or a compliance layer.
Vapi suits
Developers and product teams building their own voice products, who want full control over every part of the agent and the code around it.
| SolarDialer | Vapi | |
|---|---|---|
| Setup time | Minutes: sign up, upload your leads, pick an industry. New accounts are reviewed before their first call. | You write the agent's prompt, pick its voice, speech recognition and model, connect phone numbers, and build the campaign logic around it. |
| Scripts ready for 51 industries | Ready for 51 industries: opening line, answers to objections, qualifying questions and rules, all editable. | You write and test the script yourself; any templates are starting points, not ready-made scripts per industry. |
| Compliance gate built in | Yes: before every call, the lead's calling hours in each of its time zones, holidays, attempt limits and the do-not-call list are checked. | Building blocks only: calling hours by time zone, holidays, attempt limits and do-not-call checks for an outbound campaign are generally yours to build. Check their docs for what's included. |
| Live transfer to your closer | Yes: your closer's phone rings, they hear a short briefing, then the lead joins. | Possible: a transfer you set up and test yourself. |
| Pricing model | 22¢ a minute on our phone lines (14¢ agent + 8¢ line), or 14¢ with your own carrier. Calls nobody answers are free. | Usage-based, per minute, plus the providers you pick (model, voice, speech recognition, phone line). |
| Contracts | None. Add credit, pay for the minutes used, stop any time. | Pay as you go, with larger plans for enterprises. |

When Vapi is the better choice
Vapi is the better choice when you have developers and want to build something of your own: an inbound line, a product with voice inside it, custom tools that call your systems mid-conversation, or a use far from lead follow-up. If you'd rather build your own dialer from parts, it's a good place to start. That's how SolarDialer was built.
