There is no defensible single ranking of the 11 fastest CMS platforms from the available 2026 data: the strongest comparisons measure different things, on different dates, and with different platform cohorts. In Q2 2026 phone field data, TYPO3 has the lowest listed 75th-percentile Largest Contentful Paint (LCP) at 1.5 seconds. A separate February 2026 mobile comparison puts Duda first for the share of sites passing all three Core Web Vitals, at 85%. Those results answer different questions—not a controlled head-to-head test of identical sites.
Use the comparisons below to narrow your shortlist, then assess your own site’s field data and the requirements of your project. The figures describe observed platform cohorts, not the speed a new site is guaranteed to achieve.
What “fastest CMS” means in these rankings
Website speed can mean a fast initial load, a quick response to interaction, or a stable layout. Google’s Core Web Vitals capture these as LCP, INP, and CLS, respectively. The technical guide cited here gives the “good” thresholds as LCP under 2.5 seconds, INP under 200 milliseconds, and CLS under 0.1. A site passes all three when at least 75% of visits are good for each metric. See the Core Web Vitals definitions and thresholds.

The Q2 comparison below sorts platforms by the 75th-percentile LCP, or LCP p75.
- INP: how responsive a page is to user interactions.
- CLS: how much the page layout shifts unexpectedly.
- All-three pass rate: the share of sites or visits meeting the good threshold for all three metrics, as reported by the source.
A platform can rank well on one measure without leading another. Field data reflects real-world visits; a lab score is a diagnostic result under test conditions, not the same thing as a field-data pass rate.
Q2 2026 ranking by phone LCP
The following table reproduces the principal entries in the Q2 2026 phone field-data comparison from Core Web Vitals / Arjen Karel. The explorer describes its dataset as Chrome field data from 189,915 sites, representing millions of page loads. Its listed LCP p75 is the ranking measure; the LCP pass share is a separate metric. The site count is the platform cohort size. View the CMS performance explorer and its Q2 2026 phone outcomes.
| Rank by LCP p75 | CMS | LCP p75 | Sites passing LCP | Sites in cohort |
|---|---|---|---|---|
| 1 | TYPO3 | 1.5 seconds | 95.5% | 95 |
| 2 | Wix | 1.6 seconds | 94.4% | 5,217 |
| 3 | Shopify | 1.7 seconds | 94.8% | 7,625 |
| 4 | Drupal | 1.9 seconds | 89.9% | 2,990 |
| 5 | Joomla | 2.0 seconds | 88.3% | 2,325 |
| 6 | Squarespace | 2.2 seconds | 85.8% | 2,028 |
| 7 | Adobe Commerce | 2.4 seconds | 76.7% | 989 |
| 8 | WordPress | 2.7 seconds | 69.5% | 59,040 |
TYPO3 leads this listed LCP ranking, but its cohort contains 95 sites, compared with 5,217 for Wix and 59,040 for WordPress. That difference matters when weighing how representative each platform result may be. The explorer also displays Webflow, Ghost, and HubSpot CMS in a compact panel with 15, 37, and 5 sites, respectively, and fades rows with fewer than 100 sites. Those small cohorts are too limited to support a confident ranking alongside the principal entries.
February 2026 ranking by mobile all-three pass rate
A separate Stackra report attributes the following mobile all-three Core Web Vitals rates to the HTTP Archive/CrUX Technology Report for February 2026. This is a different date and measure from the Q2 LCP table above; do not read its order as an LCP ranking. Read Stackra’s February 2026 CMS benchmark report.

| 11 | WordPress | 48% |
| 12 | Weebly | 46% |
This report includes 12 platforms, not 11. Keeping the full set avoids arbitrarily omitting a listed platform just to match a headline count. The percentages describe the reported share passing all three mobile vitals in February 2026; they are not percentages passing LCP alone.
Why TYPO3 and Duda both lead
There is no contradiction in TYPO3 leading the cited Q2 2026 LCP-p75 table while Duda leads the separate February 2026 all-three mobile pass-rate comparison. The first ranks a particular loading metric in a later edition; the second reports the share meeting three metrics in an earlier edition. The eligible platforms differ as well. Neither source establishes which CMS would win in a controlled test with the same content, hosting, theme, extensions, and configuration.
Likewise, WordPress’s 69.5% LCP pass share in the Q2 phone comparison and its 48% all-three mobile pass rate in the February report cannot be compared as a change in performance. They use different measures and dates. The large WordPress cohort in the Q2 explorer also represents a wide range of site implementations, rather than one standard WordPress setup.

How to choose a CMS using performance data
- Choose the metric that matches your concern. For loading, compare LCP; for responsiveness, examine INP; for layout movement, examine CLS. Use an all-three pass rate when you want a combined view, and keep it distinct from any single-metric result.
- Match the audience and evidence. Check whether the comparison covers phone or desktop visits, its edition or reporting date, and whether it uses field data or lab tests. Do not combine results from different scopes into one league table.
- Check cohort size and uncertainty. A result based on a small platform cohort is less informative than one drawn from many sites. Treat especially small samples as weak evidence, not proof of a platform-wide advantage.
- Assess your site’s implementation options. Themes, plugins, templates, scripts, image handling, hosting, caching, and page construction can all affect results. Consider how much control your team has over those factors, not only the platform name.
- Use the benchmark for shortlisting, then measure your own pages. CrUX or PageSpeed Insights can provide field data where enough eligible visits exist. A lab tool can help diagnose an issue, but it does not substitute for real-user field outcomes. Small or new sites may not have enough field data for a useful report.
A November 2025 HubSpot article reports desktop all-vitals rates for a different set of CMS platforms and notes that devices, connections, geography, content, scripts, and hosting affect speed. Because that evidence is older and desktop-scoped, it should not be mixed into either 2026 mobile comparison. See HubSpot’s CMS speed discussion.
