When to choose core-js

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

When to choose SignalR

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

How this comparison was built

Scores are medians across 1599 audited core-js sites and 2 audited SignalR 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.
