Heroku outperforms React in 5 of 7 categories, with a stronger composite score (76 vs 74). React leads in no categories.
Choose Heroku when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
React doesn't clearly lead Heroku 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 10 audited Heroku sites and 1022 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.
