In 2026, two major technological families compete when it comes to creating websites:
- WordPress, the historic CMS: flexible and economical, but aging.
- Astro, a modern, ultra-fast framework designed for performance, SEO, and long-term simplicity.
Since 2024, a massive shift has been underway: SMEs, consultants and B2B companies are progressively migrating to Astro, primarily for performance, security and total cost reasons.
Here's the complete, clear and decision-oriented comparison.
Disclosure: Numinam builds with Astro for most of its client projects. This comparison is based on real-world benchmarks and publicly available data. We acknowledge WordPress strengths where they exist.
WordPress in 2026: benefits and limitations
The benefits:
- very low start-up costs,
- huge ecosystem of plugins,
- great for a simple site on a small budget,
- easy to modify without development skills.
But in 2026, WordPress has 6 major problems:
Average or poor performance
Every plugin adds JS, CSS and requests: 60–75 on mobile Lighthouse, rarely above 80. SEO and conversions suffer.
Mandatory, costly maintenance
Core, plugins, theme, security monitoring, incompatibilities: €100–500/month for proper upkeep (Q1 2026 data).
Fragile security
Around 43% of hacked sites in 2025 ran WordPress. Every added plugin is one more risk.
Frequent incompatibilities
Plugin A + plugin B = conflict. Updated plugin = broken design. Abandoned plugin = security hole.
Limited scalability
The bigger the site gets, the slower and more unstable it becomes.
Higher real cost than expected
WordPress is free… but its TCO climbs fast: maintenance, security, heavy hosting, premium plugins.

Astro in 2026: the modern framework that changes the game
Astro is a framework designed to create ultra-fast websites by generating static or hybrid pages, with a minimum of JavaScript.
Key benefits:
1. Unmatched speed
Astro produces nearly JavaScript-free pages by default. Result: Lighthouse scores of 90–100 even on mobile, pages that load in 0.3 to 1 second.
Impact:
- +25 to 60% conversions,
- better SEO,
- better user experience.
2. Native security
- No exposed database.
- No vulnerable plugins.
- No dynamic attack surface.
Astro is virtually impossible to hack.
3. Extremely low maintenance
An Astro site requires:
- 0 plugin updates,
- 0 security patch management,
- virtually no technical intervention.
Actual cost: €0 to €150/month depending on editorial needs.
4. Compatible with all modern frontends
You can integrate:
- React,
- Vue,
- Svelte,
- pure HTML.
Total flexibility.
5. Superior SEO
Speed is now a major ranking criterion. Astro + structured content = better ranking.
6. Perfect for SMEs, consultants and B2B companies
Astro lets you create showcase or corporate websites that are high-performance, without the burden of an aging CMS.

When to choose WordPress, and when to choose Astro in 2026?
Choose WordPress if…
- you have a very tight budget (under €1,500)
- you need to be able to modify your site entirely without any technical skills
- you want ready-to-use plugins (calendars, complex forms, membership areas…)
Choose Astro if…
- speed is a priority
- SEO is strategic
- you want to avoid heavy maintenance
- you want a site that stays stable for several years
- you want a premium image, with no risk of being hacked
- you're looking for a direct impact on conversions
For a simple project with low SEO expectations, WordPress remains a cost-effective option. Astro, meanwhile, is particularly well suited to established SMEs, B2B consultants and firms, premium brands, and companies competing on content, SEO or AI integration.
Concrete example: performance and conversion
Typical WordPress site
Astro site (numinam.com)
Astro often reduces loading times by a factor of 3 to 10. A page going from 3.5s to 0.9s can increase:
- conversions: +25 to +60%,
- time on page: +20 to +50%,
- SEO: +10 to +30 positions depending on the competition.
This explains the boom of Astro in modern web studios in 2026.
