WordPress Multisite development at enterprise scale
Your brand sites should feel like one organization to your customers and your teams. They rarely do, because each site runs on its own hosting, its own CMS, follows its own update cycle, and has no shared way to manage and grow multiple web properties. We bring all of that under one roof, with shared infrastructure and governance.
Trusted by the world’s leading brands
Fortune 500 marketing teams, award-winning publishers, and global automotive networks choose WordPress. Then they pick rtCamp to build it right.

What 20+ WordPress installations cost you
Plugin updates with no central owner
You can’t see what’s installed across your sites from one place. Each site gets its own plugins and its own update schedule. A security issue on one site becomes a problem for all of them.
Your brand looks different on every site
You can’t push theme updates centrally. Regional teams customize locally, fonts change, and campaign templates diverge. Brand consistency gets harder to maintain with every site you add.
Your editorial teams don’t share content
You publish a corporate announcement on the parent brand. Sub-brands copy-paste it manually and reformat it for their own templates. A content-sharing workflow never materializes because nobody wants to take on the effort of building one.
Infrastructure costs scale with site count
Every brand or region you add comes with its own hosting contract, staging environment, and deployment pipeline. Your costs grow with the number of sites, not with traffic.
No centralized visibility or audit trail
You can’t see who has admin access across all properties without checking each site individually. Analytics live in separate dashboards, user directories are in different systems, and your compliance team has no single audit log to point to.
Consolidation projects that stall mid-flight
You began consolidating standalone sites into a single network. Different WordPress versions on every property are slowing you down. The redirect map takes weeks to untangle.
Meet OnePress:Enterprise governance for WordPress Multisite
WordPress Multisite gives you shared infrastructure. There’s a single installation and database, and shared plugins and themes across every site. OnePress adds the governance controls to manage what runs on it.
We built OnePress as an open-source governance framework for WordPress Multisite with six modules, each solving a specific problem.
OneDesign
Syncs page templates and design components from a central site to every brand site. Each brand’s fonts, colors, and spacing adapt automatically. You create a campaign template once. It deploys to every brand while preserving each brand’s visual identity.
OneUpdate
Centralize plugin management with automated testing and deployment. Every plugin change goes through a review before it goes live. All brands end up running the same approved plugins, and sites stay in sync.
OneMedia
Shared media library with two modes. Sync Mode keeps logos and brand assets live-linked so updates push everywhere automatically. Non-Sync Mode copies media for independent editing per brand. One place for all your brand assets.
OneSearch
Search across all your sites at once, built on Algolia. Your users search once and get results from every connected site. Local content surfaces first and syncs automatically when you publish or update content. No manual re-indexing.
OneAccess
One dashboard for user management on every site. Assign distinct roles per property (editor on Site A, admin on Site B), handle profile requests with approval workflows, and see who has access to what in the network.
OneLogs
Unified activity logging for every site. Logins, content changes, settings modifications, and security events are aggregated into one dashboard. The audit trail your compliance team needs for every site in the network.
Your team owns the code, which is GPL-licensed. Zero licensing fees, zero vendor lock-in, and zero dependency on rtCamp after handover. Read the full OnePress architecture handbook.

Our WordPress Multisite development services
Every project starts with architecture.
Multisite network architecture and setup
Domain mapping, subdomain or subdirectory configuration, who can do what on which site, plugin rules, staging environments, and automated deployment pipelines. We design your network around governance requirements before the first site goes live.
As architected for Cox Automotive’s 8-brand network and Private Media’s 3-publication platform.
WordPress Multisite consolidation
We migrate standalone WordPress installations and non-WordPress properties (AEM, Drupal, Sitecore, Kentico, Adobe CQ5) into unified multisite networks. Your content, URLs, and SEO rankings carry over intact, and your sites stay live throughout the switch.
As delivered for Videojet Technologies: 28 sites, 12,000+ pages, 22 languages, from Adobe CQ5.
OnePress multi-brand governance
Each brand controls its own look within a network you manage centrally. Shared component libraries, content sharing across sites, centralized plugin management, and network-wide audit logging.
Cox Automotive’s shared code and design across brands went from 2% to 50%, with 70–80% code reuse across 8 brand websites.
Custom theme and plugin development for multisite
Themes designed for multisite networks, with each brand’s visual identity baked in. Custom plugins with network-level admin controls, content sharing between sites, and per-site customization without separate codebases.
Videojet’s 28 regional sites share 24 custom Gutenberg blocks reused throughout the network.
WordPress Multisite management and ongoing support
Network-wide core, plugin, and theme update cycles. Security monitoring with defined SLAs. Incident response. Quarterly architecture reviews. From light-touch updates to fully managed operations.
Ongoing services for Cox Automotive, Private Media, and Indian Express (~80M monthly users).
Exceptional work, done right
Cox Automotive achieves 103% higher engagement & 100% more leads with OnePress
Scaling multi-brand publishing: Private Media’s WordPress VIP multisite transformation
Where multisite
architecture delivers the strongest ROI
Not every enterprise needs multisite. The biggest payoff shows up in these profiles.
Holding companies managing 5 to 500+ sub-brand websites. You need unified plugin controls, shared infrastructure costs, and brand-level editorial autonomy from a single network. OnePress gives each brand independence within a centrally controlled framework.
Cox Automotive unified 8 brands with 103% engagement growth.
Regional editions, vertical publications, and shared contributor networks. Your editors need their own workflows and brand identity, while your infrastructure team needs one network to manage. Private Media cut development costs by roughly 50% across three publications and absorbed an acquisition within months.
Department sites, faculty portals, research pages, and student-facing properties. IT needs institutional oversight. Departments need editorial control. University networks scale from 50 to 500+ subsites with detailed permission controls across academic and administrative departments.
Location-specific sites with shared brand templates, promotional content pushed from head office, and local editorial controls. Brand-wide updates deploy instantly while franchisees manage location-specific content within defined boundaries.
Your brand stays consistent at every location without removing the local context that drives conversion.
Unified security controls, accessibility compliance, and content audit capabilities. WordPress VIP holds FedRAMP Moderate Authorization for US federal environments and is the only Gartner Customers’ Choice for web content management (2025).

Frequently asked questions
WordPress Multisite lets you run multiple websites from a single WordPress installation with a shared codebase, database, and admin interface. Separate installations need their own hosting, updates, and maintenance.
For enterprises managing 10+ properties, the difference shows up in governance and cost. One update cycle instead of fifty, one security standard instead of dozens, and full visibility into the entire portfolio.
WordPress Multisite has no hard architectural limit. KHM Travel manages a network that scaled to 6,500+ sites on WordPress VIP. Cox Automotive operates 8 brand websites with 103% engagement growth. Videojet Technologies manages 28 regional sites in 22 languages.
Yes. We migrate standalone WordPress installations and non-WordPress properties (AEM, Drupal, Sitecore, Kentico, Adobe CQ5, custom CMS) into unified multisite networks.
Each migration starts with a full content and technical audit covering how your content is organized, which URLs need redirecting, and what other systems connect to your sites. Your sites stay live throughout the switch.
Videojet’s migration covered 12,000+ pages across 22 languages. FleetNet America’s Drupal migration was completed in weeks with a 2x performance improvement.
OnePress is rtCamp’s open-source framework for managing multi-brand WordPress networks. WordPress Multisite gives you shared infrastructure. One installation, one database, shared plugins and themes. OnePress adds the governance controls to manage what runs on it.
That means per-brand design controls (OneDesign), centralized plugin management with automated deployment pipelines (OneUpdate), a shared media library with sync controls (OneMedia), cross-site search (OneSearch), centralized user management (OneAccess), and network-wide activity logging (OneLogs).
Yes. Videojet Technologies runs 28 regional sites in 22 languages on WordPress VIP Multisite.
The OnePress handbook documents multiple multilingual architecture models. One subsite per language, standalone installs per language, or hybrid approaches with WPML, Polylang, or MultilingualPress. For enterprises using translation management systems (Smartling, Lokalise, Phrase), custom integrations connect them to the WordPress network.
Custom enterprise WordPress development starts at around $50,000 for a single property, with multisite implementation scaling based on the number of brands and requirements. A 10-site consolidation with standard themes is a different engagement from an 8-brand unification with custom governance and migrations from legacy platforms. We provide a detailed proposal with a cost breakdown after Discovery.
Yes. Monthly WordPress core, plugin, and theme update cycles for the full network, security monitoring with defined response SLAs, incident response, and quarterly architecture reviews.
Engagement models range from light-touch updates to fully managed operations. We currently manage networks for Cox Automotive, Private Media, and The Indian Express.
Yes. WordPress VIP holds FedRAMP Moderate Authorization, SOC 2 Type 1, and ISO 27001. It supports GDPR, CCPA, and HIPAA requirements.
