What Is Hub-and-Spoke?
The Sera ecosystem is built on a hub-and-spoke architecture. Sera Core is the hub — the central brain that provides shared services to all connected plugins. Each spoke plugin handles a specific domain (security, performance, content, SEO) while leveraging the hub's capabilities.
This architecture means you only configure AI providers, manage licenses, and monitor activity in one place. Every spoke plugin automatically inherits these settings.
The Hub: Sera Core
Sera Core provides six foundational services that spoke plugins consume:
1. AI Engine
A multi-provider AI engine that supports OpenAI (GPT-4, GPT-4o), Anthropic (Claude), and Google Gemini. Configure your API keys once in Sera Core, and every spoke plugin can use AI capabilities without separate configuration.
2. Workspace
A unified dashboard where you can see the status of all installed spoke plugins, recent activity, and system health at a glance.
3. Knowledge Base
A shared knowledge store where spoke plugins can read and write data. For example, Sentinel's threat data can inform Pulse's performance recommendations, and AI Writer can reference your site's content history.
4. Hub Registry
The registry tracks which spoke plugins are installed, their versions, license status, and health. It handles auto-updates and ensures compatibility between spokes.
5. Command System
A unified command interface that allows spoke plugins to register actions that can be triggered from the Sera workspace or via the REST API.
6. Alert Center
Centralized notifications from all spoke plugins. Instead of each plugin sending its own emails, all alerts flow through the Alert Center where you can configure notification preferences.
The Spokes
| Spoke | Domain | Requires Sera Core |
|---|---|---|
| CLS Guard | Layout shift prevention | No (optional) |
| CLS Guard Pro | Advanced CLS analytics | Yes |
| Sentinel | Security & firewall | Yes |
| Pulse | Health monitoring | Yes |
| AI Writer | Content creation | Yes |
| AI Sitemap | SEO & indexing | Yes |
Spokes That Require Sera Core
Sentinel, Pulse, AI Writer, and AI Sitemap all require Sera Core because they depend on the AI Engine, Knowledge Base, or Command System. Without Sera Core, these plugins cannot function.
Spokes With Optional Integration
CLS Guard works completely standalone — it is a pure CSS solution with no dependencies. However, when Sera Core is installed, CLS Guard can report its status to the Workspace dashboard.
CLS Guard Pro requires Sera Core for its AI-powered learning mode and auto-fixer features, but its basic dashboard and analytics work independently.
How Spokes Communicate
Spoke plugins communicate with the hub through a standardized API:
- Registration — When a spoke activates, it registers itself with the Hub Registry, declaring its capabilities and required services
- Service requests — Spokes request AI completions, knowledge base reads/writes, and alert dispatches through the hub's internal API
- Status reporting — Each spoke periodically reports its health status to the Workspace
- Command registration — Spokes register their available commands with the Command System
This communication happens entirely within WordPress — there are no external API calls between plugins. Everything runs on your server.
Installation Order
For the smoothest setup, install in this order:
- Sera Core — Always first. Configure your AI provider and license.
- CLS Guard — If you need basic CLS protection (free, no dependencies)
- CLS Guard Pro — If you need advanced CLS analytics (requires Sera Core)
- Sentinel — Security should be set up early
- Pulse — Health monitoring benefits from historical data, so install early
- AI Sitemap — Configure after your site structure is stable
- AI Writer — Install when you are ready to start creating content
The Business Bundle Advantage
While you can purchase spoke plugins individually, the Business Bundle ($199/year) includes all seven plugins. Beyond the cost savings, the bundle ensures all spokes are always on the same version and compatible with each other.
Conclusion
The hub-and-spoke architecture is what makes Sera more than a collection of plugins. It is an integrated ecosystem where each component enhances the others. Sera Core is the foundation — install it first, and then add the spokes that match your needs.
