Event Guest List with Table Seating and Check-in

Event Guest List with Table Seating and Check-in is an offline app (one HTML file in a zip) for the person organising one event. You list the guests with the size of each party, group them by family or team, and add the tables with their seats. A table map shows each table filling up, and a tap on a table or a name seats people there. You mark pairs that must sit together or apart, and the app warns when the plan breaks one. On the day, check-in mode finds a guest as you type and records how many in the party have arrived.

The problem it removes: Seating plans live on a spreadsheet and a sheet of paper, someone is forgotten, two people who must not sit together end up at the same table, a table has nine people for eight seats, and on the day the door team scrolls a long list looking for a name. This app keeps guests, tables and rules together, counts the seats, flags the conflicts and finds guests quickly at the door.

What is inside:

• Guest list with party size (guest plus extra people), group, reply (Invited, Confirmed, Maybe or Declined), dietary notes and phone
• Table map with each table's seats used and free, the names seated, and a tap to seat people, with a warning before a keep apart pair or a full table is saved
• Keep together and keep apart pairs, and groups that should share a table, with the conflicts listed
• Suggest seating for people with no table: groups stay together when a table has room and keep apart pairs never share one, shown as a preview before anything is saved
• Check-in mode with a large search box, counters for arrived, still to come and expected, arrivals by table, partial arrivals for a party, and a walk in button
• Checks for conflicts, split groups, tables over capacity, guests who declined but have a table, and arrivals with no table
• Printable seating chart, place cards and an entrance guest list
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: event organisers, wedding planners, restaurant and hotel banquet teams, company administrators and families planning a seated event with a guest list of up to a few hundred people.

What it is NOT: It does not send invitations, collect replies online, sell tickets, scan codes or connect to any guest list website. It records what the person using it types. It does not know your venue's fire or safety limits: the seats on each table are numbers you enter. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (138 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 194 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
