Stack Details

Web stack

The panel itself runs on NGINX as an internal reverse proxy. Customer websites are served by Apache (managed as MyApache) or LiteSpeed. You get Multi-PHP from 7.4 through 8.5 with PHP-FPM and OPcache for better performance. CloudLinux LVE gives you per-account resource limits and CageFS keeps each account isolated. One panel, full control over the stack. No need to juggle separate configs or servers.

Email

Dovecot (IMAP/POP3) and Postfix (SMTP) handle mail delivery and access. DKIM, SPF, and DMARC are automated so you get better deliverability with less manual work. Rspamd handles spam and greylisting. Roundcube is included as webmail. On multi-server setups you can use a dedicated email node (Postfix + Dovecot) with optional clustering. One place to manage mail across all nodes.

Databases

MariaDB, compatible with MySQL 8, is available for your applications. Adminer is built in for web-based management. Automated incremental backups run in the background with one-click restore when you need it. You keep data safe without extra scripts or external tools. Everything stays inside the panel and scales with your stack.

Security

ModSecurity WAF with OWASP Core Rule Set protects your sites at the web layer. Imunify360 integration adds malware scanning and cleanup. Let's Encrypt and custom SSL are supported with auto-renewal. The server firewall and CloudLinux CageFS plus LVE give you isolation and resource limits per account. Strong defaults without locking you into a single vendor.

DNS & Domains

The full zone editor supports common record types (A, AAAA, CNAME, MX, TXT, and more). You manage domains and DNS from a single panel with consistency and less room for error.

API & Automation

The REST API covers provisioning, DNS, domains, and panel operations so you can automate billing, reseller flows, or internal tools. Web terminal gives you SSH in the browser. Python and Node runtimes plus Git deployment let you host apps beyond PHP. WHMCS integration and WP Toolkit (coming soon) round out automation and WordPress management from one place.

Python, Node.js & Ruby

The Passenger module lets you host applications built with Python, Node.js, or Ruby alongside your PHP sites, all from one panel. No separate servers or complex setup. You get technology flexibility per project, faster rollout, and lower operational overhead.
