How to Build a Wedding Website with RSVPs, Meal Choices and Guest Info

How to build a wedding website: the pages guests use, an RSVP form tied to your guest list, meal choices, privacy, and when a free wedding site is enough.

A wedding website is a guest information desk that happens to be pretty. Guests visit it to find out when and where, what to wear, how to get there, and to RSVP — so the most useful thing you can build is an RSVP flow tied to your actual guest list, plus clear answers to the questions you would otherwise field by text for months. An AI app builder can make a lovely first version in minutes. The work that matters is the guest list data, the RSVP rules (plus-ones, children, meal choices) and deciding what stays private.

What the site needs

Data

The RSVP is where a wedding site stops being a brochure and becomes a small app:

Table	Key fields
Invitations	Household name, invite code, max plus-ones, events invited to, RSVP deadline
Guests	Invitation, name, adult or child, attending yes/no per event, meal choice, dietary notes
Responses	Invitation, submitted at, message to the couple, email for updates

Modelling invitations separately from guests is the key design decision. One household gets one code; everyone on it is answered for in a single form; and you can invite some households to the welcome dinner but not others.

Permissions

Guests can see and edit only their own invitation. You and perhaps one trusted helper see the full list, counts and meal totals. Nobody else sees names, emails or dietary information.

Decisions and trade-offs

Open RSVP or guest-list RSVP

An open form ("type your name and whether you're coming") is quick to build, but you will get misspelt names, people RSVPing for guests they weren't invited with, and duplicates. A guest-list RSVP — find your invitation by name or code, then answer for the people on it — takes a little more setup and saves you hours of reconciling a spreadsheet.

Public, unlisted or password-protected

Most couples choose unlisted plus a light password (for example, your first names, or a code printed on the invitation). Also ask for a noindex tag so the site stays out of search results. A password is not bank-grade security, but it keeps casual visitors away from the address and schedule.

Meal choices and dietary needs

If your caterer needs counts per dish, collect a meal choice per adult and a separate "child's meal" option. Keep dietary notes as free text; a checkbox list never covers everything.

Languages

Bilingual weddings are common. Decide up front whether every page is translated or only the essentials, and add a language switcher in the header.

A first prompt that works

Build a wedding website for Maya and Tom, getting married on Saturday 12 June 2027 at Hollin Barn, near York, UK. Pages: home with names, date and an RSVP button showing the deadline (1 April 2027); schedule (ceremony 2pm, drinks 3:30pm, dinner 6pm, with map links); travel and places to stay; FAQ (dress code garden formal, no children except family, gifts). RSVP: guests enter the code printed on their invitation, see everyone on that invitation, and for each person choose attending or not, and a meal (beef, fish, vegetarian, or child's meal), plus dietary notes and a message. Store invitations and guests in a database; I'll import the guest list from a CSV. A private admin page shows totals (attending, declined, not yet replied) and meal counts, and exports a CSV for the caterer. Whole site behind a simple site password and not indexed by search engines. Soft, romantic design with sage green and cream, serif headings. Mobile-first.

It names the invitation model, the meal options, the admin totals and the privacy choice — the parts an AI would otherwise guess at.

Build steps

Clean up your guest list in a spreadsheet: one row per guest, grouped into invitations with a code each.
Generate the site from your prompt and check it on a phone — most guests will open it from a message.
Import the guest list and test RSVPs with a few real codes, including a household with children and one with a plus-one.
Test the edge cases: a guest changing their answer, someone entering a wrong code, an RSVP after the deadline, a declined invitation.
Admin view: totals, meal counts, a list of who hasn't replied yet, and a CSV export.
Protect the admin page with a proper login; the site password is not enough for guest data.
Optional confirmation emails via your own email provider, so guests have a record of their answers. See sending emails from your app.
Publish, connect a domain if you want a memorable address, and print that address on the invitations. Connecting a custom domain walks through it.

Common mistakes

Launching after the invitations go out. The address is printed on paper; the site must work before anyone types it in.
Open RSVP forms. You will spend the week before the wedding matching "Aunty Sue + 1" to your spreadsheet.
No way to change an answer. Plans change. Let guests reopen their RSVP until the deadline.
Putting the home address or guest list on a public page. Keep personal details behind the admin login.
Too much content. Guests want the practical facts. Keep the love story short, or last.
Forgetting the day-after page. A simple page to share photos and say thank you is a nice touch — and the site keeps being useful.

When a ready-made product is the better choice

Free wedding website services exist precisely for this, with templates, RSVPs and registry links, and for most couples they are the quickest and cheapest route. Use one if their RSVP options fit your guest list and you are happy with the designs.

Build your own when you want the site to match your invitations exactly, need RSVP rules those tools don't support (different events for different guests, several languages, detailed meal choices), want to avoid ads or upsells, or simply enjoy making something personal. If you are a planner or a venue running many weddings, a custom tool can also become a reusable product — see building an event registration site for the ticketing side.

Building it with Mythex

On Mythex you describe the site in chat and it appears in a live preview, including a phone-size view. When you ask for RSVPs to be saved, the agent adds a Postgres database to the project and can build the CSV import and export. You can publish on the Free plan to a mythex.ai address; connecting your own domain is a Pro feature. Confirmation emails and the admin login use your own providers — Mythex has no built-in email sending or end-user login. Use /test to have the agent click through the RSVP flow before you share the link.

Questions

What should a wedding website include?

The date, times and addresses, a schedule for the day, travel and accommodation tips, dress code, an RSVP form, and answers to the questions guests will otherwise text you — children, plus-ones, parking, gifts.

How do I stop strangers from RSVPing?

Tie the RSVP to your guest list. Guests find their invitation by name or a code printed on the invite, and the form only shows the people and plus-ones on that invitation.

Should a wedding website be private?

Keep the address and schedule behind a simple password or invite code if you are worried about uninvited visitors, and ask search engines not to index the site. Never put guests' personal details on public pages.

Is it worth building a wedding website instead of using a free one?

Free wedding sites are enough for most couples. Building your own makes sense if you want a design that matches your invitations, RSVP rules the free tools don't support, several languages, or simply enjoy making it.
