WedBuild vs Say I Do
Say I Do (sayi.do) is an Australian wedding website and RSVP app with a free plan and one-time upgrades, so like WedBuild it's paid for by couples. The difference is how much of the planning each one covers. WedBuild also has a budget planner, Find My Seat for guests and an AI assistant, none of which Say I Do lists among its features.

Free for up to 50 guests, with every Pro tool for your first 7 days. No card needed.
Who pays for it, and why it matters
When a wedding platform is free, someone else is usually paying for it. Here's who pays for each, and what that means for the tools you get.
WedBuild
WedBuild is paid for by the couples who use it, and nobody else. There are no vendor listings, no ads and no registry store, so every tool in it is there to make your planning easier.
Say I Do
Say I Do is paid for by couples too: a free plan, then one-time packages and paid add-ons such as SMS and a custom domain. Its FAQ says it charges upfront.
Both charge couples directly, so the difference isn't who pays. It's how much of your planning each one covers, and how long you keep it.

Why couples choose WedBuild
Couples pay for WedBuild, so everything in it is there to make planning easier: no vendor listings, no sales calls, no ads.
One guest list, from RSVP to reception
A guest's RSVP updates your guest list, dietary answer included. On Pro the seating chart shows it, table cards print with a dietary legend for your caterer, and Find My Seat uses the same list. Nothing is typed twice.
Dietaries on every plan
The RSVP asks about dietaries by default, on the free Essentials plan too. Every answer lands on the guest, ready to export for your caterer.
Find My Seat on the night
On Pro, guests scan a QR code, type their name and see their table, their seat and where it is in the room. Move someone at the last minute and Find My Seat shows the new seat.
The whole plan in one place
Your checklist and wedding day itinerary are free. The budget, with invoices and payments, is on Standard and Pro, and vendor comparison is on Pro, all next to the guest list that drives most of the cost.
Your plan stays open
