Festapp

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.

One platform, connected products

Festapp powers international and Czech ticketing services, and branded event apps such as Festival Slunovrat

Each organization configures its branding and features on the shared platform.

Ticketing for organizers

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.

Design your venue

How it fits together

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.

Path	Contents
`lib/`	Flutter application and feature modules
`packages/festapp_core/`	Portable Dart domain and sync contracts
`web_client/`	Public JavaScript client
`database/`	Canonical SQL functions, schema sources and tests
`supabase/`	Local baseline, forward migrations and Deno functions
`workers/`	Cloudflare image, sync and monitoring services
`automation/`	Configuration, builds, deployments and backend operations
`docs/`	Setup guides, architecture, runbooks and historical records

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.

Local development

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-lockfile

Complete 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 dev

For 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.

Project history

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.
