Overview

SolidCP is a free, open-source Windows cloud server/hosting control panel, evolved from Microsoft's WebsitePanel project — after WebsitePanel was discontinued, the community continued its codebase under the name SolidCP. It is maintained by a team with 15+ years of hosting industry experience, aiming to manage any number of Windows servers from a single interface.

SolidCP provides a complete hosting feature stack: IIS-based website management, DNS, email (SmarterMail/MailEnable), databases (SQL Server/MySQL), FTP, SSL, and MFA two-factor authentication, with PowerShell scripts for automated installation and upgrades. Because it is fully open source and free, it is often used as a cPanel/Plesk alternative by budget-conscious hosting providers and self-hosters.

Key Strengths

  • Completely Free and Open Source: Zero licensing cost for the panel itself, freely deployable and usable commercially — highly attractive to budget-minded cloud server operators.
  • Unified Multi-Server Management: A single panel manages any number of servers, centralizing websites, DNS, email, and databases to reduce multi-machine operations overhead.
  • Full-Featured Windows Hosting: Covers IIS websites, DNS, email, SQL Server/MySQL databases, FTP, SSL, and MFA with a complete feature stack.
  • Maintained by Professionals: Driven by a team with 15+ years of hosting experience, with community forum and knowledge-base support. See website security best practices.

Product Ecosystem

Website and IIS Management

Site management on Microsoft IIS, supporting virtual hosts, FTP accounts, application pools, and SSL certificate binding — ideal for .NET sites in the Windows ecosystem.

DNS and Domain Management

Built-in DNS zone management and domain hosting with A/AAAA/CNAME/MX/TXT records, linking websites and email.

Email Management

Integration with mail servers such as SmarterMail and MailEnable, including mailbox accounts, aliases, forwarding, and anti-spam configuration.

Database Management

Creation, backup, and permission management for Microsoft SQL Server and MySQL/MariaDB databases, covering common Windows hosting needs.

Multi-Server and Automation

The PowerShell installer and auto-upgrade tool deploy and update multiple servers in bulk, boosting efficiency when combined with automation workflows.

Limitations

  • Slow Release Cadence: Stable releases 1.4.9 (Feb 2023) and 1.5.1 (Dec 2024) are nearly two years apart, so feature and security updates lag.
  • Windows-Only Ecosystem: Relies on IIS and SQL Server, cannot manage Linux hosts; mixed environments need an additional panel.
  • Limited Ecosystem: Third-party plugins, templates, and community resources are far smaller than cPanel/Plesk, with fewer commercial integrations.
  • No Official Commercial Support: Mostly community-forum based, lacking enterprise SLAs and paid support; production environments need in-house operations capability.

Use Cases

  • Budget-Conscious Windows Hosting Providers (★★★★): A free open-source alternative to cPanel/Plesk, suited to small-scale commercial operations.
  • Self-Hosting and Internal IT (★★★★): Manage internal Windows servers and sites at zero licensing cost.
  • .NET Site Operations (★★★★): Deep integration with IIS/SQL Server, ideal for .NET application hosting.
  • Mixed Linux/Windows Environments (★★): Cannot cover Linux, so an additional panel is required.
  • Enterprise High-Guarantee Production (★★): No SLA or commercial support; evaluate carefully for critical workloads.

FAQ

  • Is SolidCP free? Yes. SolidCP is completely free and open source with no licensing cost for the panel, freely deployable and usable commercially. The main costs come from underlying licenses such as Windows Server. See server cost calculation.

  • Does SolidCP support Linux? No. SolidCP targets the Windows ecosystem (IIS/SQL Server). For Linux hosting, use another panel under the cloud server category.

  • How does SolidCP compare with cPanel? Similar positioning but different ecosystems: SolidCP is free and open source focused on Windows; cPanel is commercial and Linux-focused. The choice depends on server OS and budget. See server performance comparison.
