Mastodon outperforms React in 7 of 7 categories, with a stronger composite score (78 vs 73). React leads in no categories.
Choose Mastodon when your primary concern is server response time and security. Its audit data shows consistent strength in these areas across the sampled sites.
React doesn't clearly lead Mastodon in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Scores are medians across 1 audited Mastodon sites and 922 audited React 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.
