Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Carrd

  • Free tier strictly limited to 3 sites; any additional sites require upgrading to Pro
  • Pro plan includes Carrd branding removal but still lacks advanced features (e-commerce, multi-step funnels, complex forms)
  • Single-page design only; does not support multi-page websites or complex site structures
  • Limited template library compared to competitors like Leadpages or Unbounce
  • Annual payment required for Pro tier; no monthly payment option
  • No native A/B testing, analytics dashboard or conversion optimisation tools built-in

Spring Boot

  • Requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
  • Requires Spring Framework 7.0.8 or above and Gradle 8.14+ or Maven 3.6.3+, per Spring's own system requirements page, so older toolchains must be upgraded first
