Free Potluck Sign-Up Sheet —
See What's Still Open

List the dishes you need, share one link in the family chat or the neighborhood WhatsApp, and guests put their name next to one. The card says “2 spots open” and totals the servings, so everyone can see what is missing before they cook. No login, no app, nothing to install.

How to set up a potluck sign-up sheet

From a blank sheet to a full table takes about two minutes.

1
Set the columns

Pick the Sign-up sheet template (Name, Bringing, Serves). Type the dishes you need into Bringing, then tap the Name column and turn on People sign up in this column, so every blank name is an open spot.

2
Paste the link

Drop it into iMessage, WhatsApp, Slack or your Facebook event. The card shows the table, marks the open spots and totals the Serves column; sharing the link again posts a card with the latest.

3
Watch dishes fill in

Guests tap an open spot and type their name, or add a row for a dish you did not list. The page picks up everyone else's changes within seconds, no refresh needed.

Built for group chats, not for spreadsheets

⚡
No account wall

Anyone can add a dish, even the cousin with the Yahoo address from 2004. A Google Sheet can be opened to anyone with the link too, but it is a full spreadsheet to pinch and zoom on a phone; this is a table built for tapping, with nothing to install.

📲
The card shows what is missing

In every chat app the preview is the table itself: dishes, names, “Open” in the empty spots and the servings total. People see the gap before they even tap.

🔒
You stay in control

Choose whether guests can add rows, edit other people's cells or change the columns; they can always fix their own. The organizer link also shows Link Insights: how many opened the sheet, how many signed up and which chat they came from.

Potluck column ideas

Mix and match depending on how much structure you want.

Minimal
Name + Dish

Two columns, no fuss. Perfect for a casual Friendsgiving or the office potluck.

By course
Course + Dish + Name

Make Course a Choice column (Starter, Main, Side, Dessert, Drinks) so guests see which course is thin. Or use a List in the Board layout: a tile per course, a row per dish.

Allergy-aware
Name + Dish + Contains

A Contains column for nuts, gluten or dairy lets guests with restrictions scan the table at a glance.

Headcount mode
Name + Dish + Serves

Serves is a Number column, so the totals row adds it up and you know whether the food matches the guest list.

Potluck sign-up sheet FAQ

Is this potluck sign-up sheet really free?
Yes. It is free, with no credit card, subscription, trial or account. You make the sheet and share the link.
Do guests need to sign up or create an account?
No. Anyone with the link adds their dish from their phone. No login, no email verification, no app, so grandma can join from her iPhone.
Can I prevent duplicate dishes?
List the dishes you need and make Name the sign-up column. Guests claim a listed dish instead of guessing, and everyone sees what is taken before they add their own.
Does it work in iMessage, WhatsApp and Slack?

Can I edit or close the sheet after sharing?
Yes. Your private organizer link lets you edit any row, change the columns and permissions, or close sign-ups once the table is full.
What if I need RSVPs as well?
Start the Potluck plan: one Hub link with an Event for the RSVPs, the Who's bringing what sheet, a theme vote and a note with the address and parking.
