Event planning, tasks, venues, invites, menus, and coordination — one operating system so the spreadsheet stays hidden and the party shows up front.
Plan it together, design invites and menus worth sharing — then keep every guest, task, and detail in sync, in one place.
Every event gets a living task board — due dates, owners, and status chips that match what you see in the app. Add a dinner and grocery prep appears on your list; lock the menu and catering follow-ups schedule themselves.
See planning tools →Shortlist venues with capacity and notes, then switch to the seating editor — round tables, rectangles, and guest counts per table, just like your event workspace.
Explore venues & seating →Send personalised invites, watch RSVPs roll in with dietary details and meal choices — each guest gets their own RSVP link, all managed without leaving PartyOS.
Explore guest tools →Ask PartyOS AI to draft messages, assign co-planners with the right permissions, and surface notifications when tasks or RSVPs need your attention.

Meet your co-pilot →Yes — Confetti is free forever. Two active events, fifty guests each, full budgeting and RSVP tracking. We only charge when you want AI, shopping list export, or to host bigger gatherings.
You tag relationships (family, friend, colleague), optionally add notes like "introvert" or "avoid seating with Dan", and the engine builds a seating chart that encourages conversation and keeps conflicts apart. Every suggestion is editable — drag and drop to move anyone.
Once guests have RSVPed and meal selections are in, PartyOS generates a per-dish breakdown — how many of each dish, by course — that you can export as a CSV and hand straight to your caterer.
Co-planners are in on the Host and Production plans. Choose between editor, contributor, or view-only roles. Changes show up immediately, everywhere.
Dietary info, health notes, and guest relationships are encrypted and stored securely on AWS infrastructure. We never share guest data with third parties, and you can delete an event — and everything in it — in one click.
Yes. Cancel from your account settings and your plan stays active until the end of the billing period. Your events stay on the free tier afterwards — nothing gets deleted.
Every great gathering is secretly well organized. PartyOS keeps planning behind the scenes and the joy up front.
