Requirements & hosting

Application requirements

Component	Requirement
PHP	8.4 or a compatible later version accepted by the supplied Composer lockfile
Composer	2.x; verify with `composer check-platform-reqs --no-dev`
PHP extensions	All extensions required by `composer.lock`; commonly curl, PDO/MySQL, zip, mbstring, XML/DOM, fileinfo and OpenSSL
Database	MySQL; choose a maintained version and validate migrations on that exact version
Web server	Nginx or Apache with its document root set to `backend/public`
Frontend build	Node.js compatible with the locked Vite dependencies; use Node 22 LTS for the build environment
Background services	A scheduler every minute and a persistent worker for asynchronous jobs
HTTPS	Required for a customer-facing deployment
Real-time features	Persistent Reverb process and WebSocket proxy when enabled

The backend README's MySQL 5.7 and Node 18 entries are historical minimums, not a current hosting recommendation. The supplied lockfiles and target-platform validation are authoritative.

Choose your hosting

Platform	Confirm with the provider
Linux VPS	Compatible PHP/CLI, database, SSH, cron, web server and process manager
cPanel / Plesk	Compatible web and CLI PHP, Composer/SSH, configurable document root, cron and persistent workers
Shared hosting	All requirements above; many plans cannot run workers or WebSockets
Windows / IIS	PHP/MySQL compatibility, URL rewriting, scheduling and service management; separate acceptance required

Prefer a VPS for live chat, calls and other real-time features. Cloudflare DNS/proxy does not provide a PHP runtime or MySQL database.

Verification status

Fresh-installation acceptance on cPanel, Linux VPS, Plesk/Apache and Windows remains pending. Local regression tests do not certify these hosting environments.
