When to choose core-js

core-js doesn't clearly lead SolidJS in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.

When to choose SolidJS

Choose SolidJS when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.

How this comparison was built

Scores are medians across 1627 audited core-js sites and 4 audited SolidJS sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.

FAQ

Based on real BeaverCheck audits, SolidJS sites score higher on Lighthouse performance (54 vs 36 on average).
Which has better security, core-js or SolidJS?
SolidJS sites score higher on security analysis (66 vs 65 on average).
Which has better accessibility, core-js or SolidJS?
Accessibility scores measured by Lighthouse WCAG 2.1 checks favor SolidJS (94 vs 88). Both technologies can be made fully accessible with care — the difference reflects common patterns in the sampled sites, not inherent platform limits.
Which is better for SEO, core-js or SolidJS?
SolidJS sites score higher on Lighthouse SEO signals (92 vs 91 on average), which cover meta tags, crawlability, mobile friendliness, and structured data. Content strategy and backlinks still matter more than platform choice for ranking.
Which has faster server response (TTFB), core-js or SolidJS?
SolidJS sites show lower Time to First Byte (68 ms vs 385 ms on average). TTFB depends heavily on hosting and CDN setup rather than the technology itself, but the sampled sites suggest a meaningful difference in common deployment patterns.
Should I choose core-js or SolidJS for my website?
Both platforms have trade-offs. SolidJS scores higher on overall composite score while core-js may excel in metrics you care about most. Run a free BeaverCheck audit on a real site using each to compare the metrics relevant to your use case.
