Festapp is an event platform for festivals, conferences and community events. Attendees browse programs, explore venue maps and save their personal schedule on iOS, Android and the web. Organizers manage registration, tickets, reserved seating, payments and admission.
The same platform powers branded festival apps such as Festival Slunovrat, the international Festapp Tickets service and the Czech vstupenky.online portal.

Each organization configures its branding and features on the shared platform.
- Ticket sales and registration. Build public forms with ticket types, prices, capacity limits and attendee questions; share a link or embed a form on your website.
- Reserved seating. Design your venue layout and let buyers select seats when purchasing tickets.
- Orders and payments. Manage orders, track payments and match bank transfers. Online payment options depend on the event's configured provider.
- Tickets and admission. Customize PDF tickets, deliver them by email and verify QR codes with the browser scanner.
- Event operations. Coordinate volunteers, participant groups, accommodation and reception, with event-specific branding and permissions.
Create venue plans with tables, seating sections and balconies. Buyers choose their seats directly from your plan, as shown here in Lucerna's Grand Hall.
Create tickets with your own artwork, event details and seat information. Each ticket includes a QR code for admission checks.
Track orders and payments from the event administration.
Website plugins and connectors live in the integration directory, together with their setup instructions and publication status.
Create an event, prepare its program and seating plan, set ticket categories and prices, and work with orders, sales and guest check-in through a supported MCP client. The global Festapp connection includes Festapp Tickets.

Sign in to the selected environment and approve the events and functions the connection may use. Available actions depend on your current account rights, client profile and enabled application features.
Try: “Prepare a ball for 180 guests, with tables of six and two ticket categories.”
These URLs connect to the hosted service. See the connection guide and catalogue for supported clients and capabilities; the developer setup below builds the app.
Attendees can browse schedules and venue maps, read news, sign up for workshops and save a personal program on Android, iOS and the web. Each event can include information pages, songbooks and group games.
For the summer Slunovrat festival in Opava (June 18-21, 2026), visitors can follow the program, find venues on the map and explore artist profiles.

Flutter handles the mobile app and web administration. A separate vanilla JavaScript client handles public forms, checkout and the browser scanner. PostgreSQL RPCs own business rules and permissions. Deno Edge Functions connect those commands to email, ticket generation and external services.
Production uses self-hosted Supabase at https://api.festapp.net. Cloudflare
Pages hosts the combined web bundle; Workers and R2 provide image and sync
services. Server setup, application configuration and web publication are
separate steps.

Shared code lives on main. Production branches carry approved tenant overlays.
automation/project.conf supplies public configuration; apply_config.sh
generates the corresponding app and platform files. Private credentials stay
outside Git and browser assets. A tenant's activation document identifies its
live backend, organization and generation.
For details, use the documentation map, architecture context and tenant overlay policy.
Install Git, Node.js, pnpm 11.24.0 and FVM. Use the Flutter version specified by
FLUTTER_VERSION in automation/project.conf. From the repository root:
fvm install
fvm flutter pub get
(cd packages/festapp_core && fvm dart pub get)
pnpm --dir web_client install --frozen-lockfileComplete the configuration and backend setup before running against event data. Then choose a frontend:
fvm flutter run -d chrome
# Or, in another terminal:
pnpm --dir web_client run devFor client checks, run ./automation/test_client.sh. JavaScript checks use
pnpm --dir web_client test; SQL tests require the isolated local database.
The wider test_all.sh wrapper has environment-dependent skips and warning-only
lanes, so its exit status alone is not an all-suite pass. The exact commands and
limits are in Contributing.
Festapp began with volunteers building an app for Absolventský Velehrad in 2023. CHANGELOG.md records development history. Updates are also shared in the Czech WhatsApp channel.
