System requirements
Tickessa uses a static web-app build, a PHP API and your own MySQL or MariaDB database.
Intended server environment
- Apache or managed Nginx with a configurable document root.
- PHP 8.2–8.5.
- PDO MySQL, mbstring, OpenSSL, fileinfo, DOM, Sodium and ZIP; IMAP additionally for email retrieval.
- MySQL 8 or MariaDB 10.6 or newer, with InnoDB and
utf8mb4. - HTTPS with a valid certificate.
- An HTTPS or PHP CLI cron job for mailbox retrieval.
Neither the static documentation site nor the shipped frontend needs a permanent Node.js process. Node.js and pnpm are required only for local builds and release packaging.
Installation and updates
The web package from 0.13.0 includes initial setup and update assistants. The installation guide covers FTP/FTPS, SFTP, SSH, webroot, database, diagnosis and recovery. Release notes describe the combinations actually tested.
