Invites that get answered.
RSVP99 is a calm place to plan an event, send one link and see who is coming, without chasing anyone.
What you get

A name, date, time, place and cover photo. Everything a guest needs sits on one page.

Guests confirm or decline in two taps.
Guest lists

How it works
Make the event
Fill in the details and add a cover.
Send the link
Guests open it and answer.
Watch replies arrive
Track who is in, out or still thinking.
Made for gatherings of every size
Birthdays and dinners
Small lists where you just want a quick headcount before you book the table.
Team days
Offsites, workshops and lunches. Import the team from a CSV and see who still needs a nudge.
Weddings and showers
Keep guests, emails and answers in one list, and export it for the caterer.
Clubs and classes
Recurring meetups are easy: edit the date, copy the link again and send it on.
Community events
One public-friendly page with the time, the place and what to bring.
Reunions
Track who is coming from far away, and email everyone who is going in one click.
What your guests see
No sign-up, no app, no password. Your guest opens the link and sees the plan, then answers.
- Your cover photo, event name, date, time and place
- Your notes: dress code, parking, what to bring
- One field for their name
- Two big buttons: going, or cannot make it
- A friendly confirmation once they reply
Reminders that sound like you
When replies are slow, open a ready-written email in your own mail app. Guests are added as blind copies, so nobody sees anyone else's address.
- Remind only the guests who have not replied
- Send a confirmation to everyone who is going
- Edit the message before you send it
Hi,
A quick reminder to reply to Rooftop dinner on Fri, Nov 6, 2026 at 7:00 PM.
RSVP here: your invite link
Thanks!
High mode and Lite mode
High
The full show, best on a recent phone or laptop.
- A 3D paper envelope that opens as you scroll
- It tilts gently toward your pointer
- Page transitions, floating labels and reveal-on-scroll
Lite
The same envelope drawn in plain CSS, for older or low-power devices.
- No 3D, no scroll effects, no page transitions
- A small looping envelope animation instead
- Lighter on battery and memory
Nora keeps her face in both modes. Use the toggle in the top bar to switch at any time. RSVP99 starts in Lite on devices that report limited memory or ask for reduced motion, and remembers your choice.
Good to know
Do guests need an account?
No. They open the link, type their name and answer. Nothing to install.
Where are replies stored?
Everything lives in the browser that holds it. The invite link carries the event details, and a guest's reply is saved in the browser they used to open it. To collect answers in your own list, set each guest's status yourself in the event, or import a CSV.
Can I change an event after sharing the link?
Yes. Edit it any time, then copy the link again so it carries the new details.
How do reminders work?
RSVP99 opens a draft in your email app addressed by blind copy to the right guests. It needs an email address on each guest, and you press send yourself.
What happens to my data?
It stays in this browser. Clearing your site data removes it, so export a guest list to CSV now and then as a backup.
Does it work on a phone?
Yes. The layout adapts to small screens, and Lite mode keeps older phones smooth.
RSVP99 keeps everything in your browser. Clear your site data and your events go with it.
