An event website builder with RSVPs built in

The best event website builder is the one that turns a description into a working site guests can actually reply to, without asking you to learn a new tool. A few things separate the good ones from the rest:

• Guest replies – whether an RSVP or registration form is built in, not bolted on
• Your data – who actually holds the guest list once people start replying
• Change speed – how fast you can update the schedule the night before the event
• Cost – what's free to publish and what's gated behind a paid plan
• Phone view – whether the page and the RSVP form work cleanly on a phone

Base44 is an AI website builder: describe your event once and get a site with the schedule, venue details and an RSVP form built in, live on a free address and yours to change in chat as plans move.

Base44 builds your event website from a single description, with the pages, schedule and RSVP form already in place.

• Start with one example – describe the event the way you'd tell a friend, like "a company holiday party with the date, time, address and an RSVP for a plus-one and meal choice"
• Ask for exactly what you need – add or drop RSVP fields anytime, from session picks to dietary needs
• Keep shaping it in chat – swap the venue, rename a button or add a new section whenever plans change
• Decide on a domain early or late – start on a free address and connect your own domain the moment it matters

However you start, this event website builder keeps the site live and editable from the first draft to the last guest who RSVPs.

Yes. Base44 builds the RSVP or registration form with exactly the fields you name, and every answer saves straight to your site's own database. Guests can submit a reply, but only your team can read or edit the guest list.

Common fields people ask for:

• Plus-one – so you know who's actually coming
• Meal choice – for catering headcounts
• Session pick – when a conference has parallel tracks
• Dietary needs – allergies, restrictions, anything the caterer should know

Each guest can also get a confirmation email with their details, once you've connected your own domain on a paid plan.

A working event website covers a short list well, and Base44 builds each section straight from your description:

• Date, time and time zone – written out, not left to guesswork across time zones
• Venue and directions – the address and how to actually get there
• Schedule – what happens and when
• Speakers or hosts – who guests will see or hear from
• RSVP or registration – so you know who's coming
• Guest FAQ – parking, dress code, accessibility, anything people would otherwise text you to ask
• Contact – one way to reach a real person with a question

Keep it as real text, not a flyer image, so guests can copy the address straight into their maps app, and screen readers and search engines can read it too. That matters more than ever: mobile reached a record 56.4% of US online holiday spending in 2025, so an RSVP form and the details guests need most have to work cleanly on a small screen.
