adminbolt is a hosting control panel designed for shared hosting companies that require stability, scalability, and predictable operations at scale. Built by a team with hands-on hosting experience, it focuses on real operational needs rather than theoretical feature sets. The platform provides full management of core hosting services, including web server configuration, DNS zones, email services, SSL certificates, databases, and multi-PHP environments. All essential hosting functions are accessible through a single interface, allowing providers to manage customer accounts, domains, and server resources efficiently. adminbolt includes native multi-server management, enabling administrators to control multiple machines from a unified dashboard without relying on external tools. The system is designed to maintain predictable performance under load and support high account density per server, which is critical for shared hosting environments — especially with rising hardware costs.

Unicorn Panel is a self-hosted, multi-server web hosting control panel built for hosting fleets. One Primary panel manages any number of workload hosts, so you can provision and monitor every website, database, mailbox and DNS zone from one place, with no per-server logins. Every site runs in its own container with its own user and limits. Pick a web engine per site (Sleipnir, NGINX, Apache or OpenLiteSpeed) and any PHP version from 5.6 to 8.5. Databases include MariaDB, MySQL, PostgreSQL and Mimir. The Hermes mail suite includes spam filtering and Roundcube webmail, and a WordPress toolkit handles updates and logins. Upgrade server roles and the panel itself across the whole fleet in one click. Includes fleet-wide malware scanning, a firewall, per-resource backups with selective restore, and white-label branding for resellers. Built on Alpine Linux and utilizing Podman for both amd64 and arm64 architectures, the platform is equipped with a REST API and CLI. Free for 2 servers.
