WebCalendar for WordPress
A professional-grade calendar plugin with recurring events, multiuser permissions, and blazing performance. The only major WordPress calendar with full RFC 5545 recurrence support in the free tier — and a fully self-hosted Google Calendar alternative that keeps your events on your own site.
Why WebCalendar?
Built from the ground up for performance, flexibility, and a generous free tier that doesn’t hold essential features hostage.
Free
Recurring Events
Full RFC 5545 recurring events in the free tier. Daily, weekly, monthly, and yearly patterns with end conditions. The Events Calendar puts it behind a $259/year plan.
326 KB
Lightweight & Fast
Only 326 KB of JavaScript and CSS loads on a visitor’s page — the admin bundle never touches a public request. Custom database tables handle 100K+ events with no Custom Post Type bloat.
SEO
Search Engine Ready
Single event pages with Schema.org JSON-LD, Open Graph meta, canonical URLs, and XML sitemap integration. No duplicate page issues.
40
REST API Endpoints
Full CRUD access for events, categories, holidays, and more. Build custom integrations or headless calendar frontends. View API docs.

Free
Recurring Events
Full RFC 5545 recurrence in the free tier, including editing a single occurrence without touching the series. The Events Calendar puts recurring events behind a plan starting at $259/yr.
0
Rows in wp_posts
Events live in dedicated indexed tables. The Events Calendar stores every event as a WordPress post, so your posts table — and every query against it — grows with your calendar.
100K+
Events at Scale
Custom tables, not Custom Post Types. Competitors struggle above 10K.
29
Free API Endpoints
Full CRUD in the free tier. Competitors lock API access behind Pro.
Level 9
PHPStan Static Analysis
The strictest level. Fewer than 5% of PHP projects achieve this. Competitors don’t publish theirs.
89%
Test Coverage
1,000+ automated tests across unit, integration, and E2E suites. Competitors don’t publish coverage.
100+
Country Holidays (Free)
Import national and regional holidays automatically. No major calendar plugin offers this at any price.
MCP
AI Assistant Built-In
A built-in MCP server and Abilities API integration — free in every edition. No major calendar plugin supports this. An optional read-only mode keeps assistants view-only. Setup guide.
Competitor pricing and features verified July 27, 2026, and subject to change without notice.

Built for Real-World Use

Works Where You Do

Built for Quality, Informed by Experience
WebCalendar for WordPress isn’t a first attempt. It’s the product of 25 years solving real-world scheduling problems, rebuilt from scratch with modern architecture and hard-won lessons about what actually scales.
25 Years
Calendar Development Experience
Two and a half decades of building calendar software for thousands of users. Every design decision — from custom database tables to RFC 5545 recurrence handling to multiuser permission models — reflects lessons learned the hard way about what works at scale and what doesn’t. This isn’t theory; it’s battle-tested knowledge distilled into a modern, clean codebase. Learn more about our team.
AI Assistant Ready
A built-in MCP server — free in every edition, including the WordPress.org release. AI assistants like Claude and ChatGPT connect directly to your calendar — no additional plugins required. List events, create recurring schedules, reschedule meetings, and query categories with natural language. Prefer to keep AI view-only? A one-click read-only mode hides the create, update, and delete tools entirely. View MCP setup guide.
89% Test Coverage
Over 1,000 automated tests across unit, integration, and end-to-end suites. PHPStan Level 9 static analysis — the strictest level, which fewer than 5% of PHP projects achieve. GitHub Actions CI on every commit.
Clean Architecture
All business logic lives in a standalone core library, separate from WordPress. Stateless services, repository interfaces, and domain entities. No spaghetti code, no global state.
Security First
Nonce verification on every endpoint. Input sanitization. Strict permission checks with WordPress capabilities. SQL-level access filtering for private events. Psalm taint analysis. See our security policy for vulnerability reporting.
