BlogGuides and tipsCustomer storiesHow teams use ZeegResearchNumbers from real bookingsChangelogNew in ZeegZeeg answers calls and books appointments in one product, set up in minutes without writing code.
When a caller wants an appointment, Zeeg’s AI phone agent checks real-time availability on your Zeeg booking pages, books the slot during the call and sends a confirmation email. Callers can also reschedule or cancel an existing appointment by phone. Online and phone bookings use the same availability and rules, including round robin for teams. Vapi is a platform for developers, and its documentation describes an appointment assistant that you build yourself: a Google Calendar tool to check availability and create events, plus the tools and instructions for customer lookups and confirmations.
In Zeeg you start from a prompt template, adjust it with the built-in prompt builder, choose a voice and language, connect a phone number and test the agent in the dashboard before it takes a real call. Every new account has 5 free test minutes. You buy a number in Zeeg or connect your own SIP trunk. Vapi calls itself a developer platform: for each assistant you choose the transcriber, the language model and the voice provider, and Vapi covers hosting and orchestration. That suits teams that want to control every part of the pipeline.
Zeeg stores all data on servers in Europe, on every plan, encrypted at rest and in transit. A data processing agreement is included, and privacy controls for each agent let you choose whether to save transcripts and personal data, record calls and recognize returning callers. According to the privacy policy of Vapi Inc., data from outside the United States is transferred to the US and processed there. Vapi’s documentation says its EU region, with a separate EU dashboard, API and SIP endpoints, is available only with the Premier Success Package, which you arrange with its sales team.
A routing form asks, for example, about the request or region and sends the booking to the right team. Existing customers can go to their contact owner in HubSpot, Pipedrive or Salesforce first, and round robin distributes everyone else by your rules, whether the appointment is booked by phone or online. All of this is in the Business plan for €16 per user per month, billed annually. In Vapi, which calendar a call books into depends on the tools and instructions you set up.
Zeeg's key features at a glance.
Your prospects book around the clock. Connect Google, Outlook, Exchange, iCloud or CalDAV, set your own availability rules, and Zeeg prevents double bookings across all your calendars.
Ask questions at booking and use routing forms to send prospects to the right person on your team, based on answers like company size or region.
Zeeg automatically distributes incoming meetings across your team, using rules you set.
Your AI phone agent answers calls, books new meetings during the call and reschedules or cancels existing ones. You get a summary and a transcript for every call.
Embed your booking page on your website as an inline widget, pop-up button or pop-up link, in your brand colors. Or share it by link and QR code.
Zeeg creates the meeting link for every booking automatically, for Zoom, Microsoft Teams, Google Meet, Webex, alfaview or Demodesk.
Set triggers for new bookings, cancellations, meeting start and end. Reminders and follow-ups go out automatically by email and SMS.
Collective meetings find times when everyone involved is free, with shared booking links and availability for the whole team.
Collect payments at booking through Stripe or PayPal. That secures prepayments and reduces no-shows.

Verified“I’ve now set up five clients with Zeeg, including law firms, media agencies and a skin clinic, and for all of them the AI voice agent matters most. It answers calls on holidays and after hours, answers callers’ questions and books the appointment straight into the business’s Google or Outlook calendar.”
Verified“Every morning, the first thing I check in Zeeg is what our AI voice agent has arranged since yesterday. It asks callers the first questions and then books the right appointment. […] The agent also calls out on its own: contacts we want to follow up with get a call with their own greeting at a set time.”
Verified“The practical, simple setup of the AI voice agent deserves a special mention. The AI voice agent also sounds authentic and helps us take customer enquiries and bookings 24/7.”
Verified“Zeeg lets us tailor scheduling to every one of our use cases. We mainly use round robin and group events with specific presets that are easy to set up.”
Verified“We used to use Calendly and have now switched to Zeeg.me completely, and honestly, I’m thrilled!”
Verified“I add the link to every email to recruiters, and they pick a free time themselves. Thanks to the two-way sync with my Google Calendar, only times when I’m not in a lecture or another call show up, so I haven’t had a single double booking.”
Verified“Round robin events and adding the link to our email signature and website are super easy. The prices are more than fair […]”
Verified“Especially when handling client data, it matters who stores the data, where and how. […] Zeeg is a very good German alternative here: easy to use, with every feature you need.”
Verified“Zeeg makes scheduling with my clients easier every day. I send my clients the link, and they can easily book a time that suits them.”
Calendars, video conferencing, CRMs, payments, analytics and single sign-on: Zeeg connects to the tools your team already works with.
Monthly minute packages, separate from your scheduling plan. The bigger the package, the lower the price per minute. Custom packages on request.
Zeeg is a Vapi alternative for businesses that want a working AI phone agent without building one. The agent answers and makes calls in 23 languages and books appointments on your Zeeg booking pages. You set it up in the dashboard from a template and test it before it takes a real call. Data is hosted on servers in Europe.
According to Vapi’s pricing page (as of October 2026), Vapi charges a hosting fee of $0.05 per minute plus the cost of the transcriber, language model and voice you choose, passed through at cost. Calls through Vapi’s own telephony or SIP are free, and external telephony providers charge their own rates. For 1,000 minutes with Deepgram, OpenAI and ElevenLabs, the page estimates $82 to $129 per month. Success packages are optional: Core costs $29 per month, Pro has a minimum of $999 per month, and Premier is priced on request. Zeeg sells AI minutes as credit from €10 for 40 inbound minutes (€0.25 per inbound minute, €0.35 per outbound minute) or in packages from €49 per month, billed annually, with 250 inbound or 178 outbound minutes. Larger packages lower the rate to about €0.11 per inbound minute. Phone numbers cost extra per month, for example €1.21 for a German local number. Scheduling is free from the Starter plan. On top of the minutes, Zeeg includes booking pages and ready-made appointment booking that you do not have to build.
Vapi has a Google Calendar tool that checks availability and creates events during a call, and its documentation includes a guide for building an appointment scheduling assistant. You configure the tools and instructions yourself. Zeeg’s AI phone agent books on Zeeg booking pages without extra setup, and callers can reschedule or cancel by phone. Online and phone bookings share availability and rules, and appointments sync with Google, Outlook, Exchange, iCloud and CalDAV calendars.
Zeeg stores all data on servers in Europe on every plan and includes a data processing agreement. According to the privacy policy of Vapi Inc., data from outside the United States is transferred to the US and processed there. Vapi’s documentation says its EU region, with a separate EU dashboard, API and SIP endpoints, is available only with the Premier Success Package, and that Vapi does not support on-premise deployments. Vapi’s FAQ states that it is GDPR compliant.
Vapi is a platform for building voice agents into your own products, with an API and SDKs. If you want a ready-to-use AI phone agent with appointment booking in one product, Zeeg fits better.
There is no import of Vapi assistants. You create the agent in Zeeg from a prompt template, paste your instructions into the prompt builder, add your documents as a knowledge base and choose a voice and language. For the phone number, you buy a new Zeeg number, connect a number you own through a static SIP trunk, or forward your existing business number to your Zeeg number. Test the agent in the dashboard with the 5 free minutes every new account gets, then switch your line over.
