EmDash CMS vs Joomla: Which One Should You Choose?
Joomla occupies an unusual position in this series: it's not growing, and it's not the platform most teams are actively choosing for a new project in 2026 — but a meaningful number of existing sites still run on it, and the question of whether to stay or migrate is a real one. This guide is written for that decision specifically, comparing Joomla's current trajectory against EmDash's newer, structured-content approach.

Quick Answer
Stay on Joomla if your site is stable, your team already knows the platform well, and you're not hitting a specific wall it can't solve. Consider EmDash if you're evaluating a migration anyway, want structured content and modern plugin security, or you're starting a new project and were only considering Joomla out of familiarity rather than because it's the strongest current option.
Joomla's Market Trajectory
Joomla dropped from 9.3% CMS market share in 2014 to 1.9% in 2025 — an 80% decline. Joomla and Drupal collectively held around 17% market share a decade ago; now they make up less than 5% combined.
That decline hasn't reversed. Joomla currently holds roughly 2.6% of the CMS market, positioning it as a distant third behind WordPress and Shopify, while WordPress itself holds around 60% of the CMS market. It's important to be precise about what this means: Joomla hasn't become worse software over that decade — the broader market moved toward website builders and headless architectures, and Joomla's traditional "WordPress alternative with more built-in flexibility" positioning became a smaller niche as those adjacent categories grew.
Why Joomla Existed: A Middle Ground That Narrowed
For years, Joomla's pitch was straightforward: more structural flexibility than WordPress out of the box, without Drupal's steep learning curve. That middle ground has narrowed from both directions — WordPress absorbed much of that flexibility through better core features and plugins, while Drupal continued deepening its enterprise capabilities. EmDash occupies a comparable conceptual space today (more structure than a typical blog CMS, less configuration depth than Drupal), but starts from a fundamentally different architecture: structured JSON content and sandboxed plugins, rather than Joomla's more traditional PHP-and-database model.
Extension Ecosystem
Joomla's extension marketplace is real but modest next to WordPress: roughly 5,148 extensions on the official directory, versus WordPress's tens of thousands of plugins. The upside reviewers consistently note is that Joomla's smaller catalog skews more technical and reliable, built by and for people who already understand the system, rather than the highly variable quality that comes with WordPress's much larger long tail. EmDash's plugin ecosystem is smaller still — it's a newer platform — but it's built on a sandboxed permission model from the start, rather than the unrestricted access pattern both WordPress and Joomla extensions have historically had.
Should You Migrate an Existing Joomla Site?
This depends more on your specific situation than on Joomla's market trajectory in the abstract. A stable Joomla site that isn't causing problems doesn't need to move just because the platform's overall share has declined — market share isn't the same as quality or suitability for your specific use case. The stronger signals for migrating are usually: struggling to find Joomla-specific developers, hitting content-structure limitations the platform can't solve cleanly, or needing the kind of API-first, multi-channel delivery Joomla wasn't built around.
Where Joomla Still Holds Up
- An existing, working Joomla site doesn't need to move for its own sake — stability has real value.
- More built-in structural flexibility than a default WordPress install, without a full framework-level rebuild.
- A smaller but more technically-curated extension ecosystem than WordPress's much larger, more variable one.
- Two decades of accumulated documentation and community knowledge for common use cases.
Where EmDash Pulls Ahead
- Structured, typed content designed for multi-channel delivery, not just a single rendered website.
- Sandboxed, permission-scoped plugin security as an architectural default rather than a legacy extension model.
- Active, current development momentum on a platform built for 2026's constraints, not 2005's.
- Built-in AI-native tooling (an MCP server) with no equivalent in Joomla's extension catalog.
Frequently Asked Questions
Is Joomla still maintained in 2026?
Yes — Joomla is still actively developed and maintained, even though its market share has declined significantly. Declining share reflects the broader market shifting toward website builders and headless platforms, not the project being abandoned.
Is Joomla harder to use than WordPress?
Generally considered somewhat more complex out of the box, in exchange for more built-in structural flexibility without needing as many third-party plugins to get there. It sits between WordPress's simplicity and Drupal's full configuration depth.
Why has Joomla's market share fallen so much?
Mostly the same forces affecting Drupal: website builders like Wix and Shopify absorbed the simpler end of the market, while WordPress consolidated the middle through a much larger plugin ecosystem and community. It's a market-shape shift more than a Joomla-specific failure.
Does EmDash have a Joomla migration path?
Not an automated one today. Migrating means rebuilding content in EmDash's structured format — real effort, but a one-time cost, and one that pays off if you're moving toward API-first, multi-channel content anyway.
The Bottom Line
If your Joomla site is stable and serving its purpose well, its declining market share alone isn't a reason to migrate. If you're evaluating options for a new project, or your existing site is hitting real structural or extensibility limits, EmDash's structured content model and sandboxed plugin security represent where the category has moved since Joomla's peak.
