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

Sphinx

  • reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
  • Configuration is complex and the default output is dated-looking without theme work
  • Build times on large documentation sets are slow
  • Heavier than the problem for a small project that only needs a few pages

Carrd is free for up to 3 sites. The Pro plan costs $19/year and enables unlimited sites with custom domains, forms and integrations.

Source
Sphinx: Is Sphinx free?

Yes, open source under the BSD licence.

Carrd: Can I use Carrd for e-commerce?

Carrd's Pro plan supports payment forms with Stripe integration, but it is not a full e-commerce platform. Single-product sales or payment collection is possible, but inventory management and complex product catalogs are not supported.

Sphinx: Do I have to write reStructuredText?

Not any more. The MyST extension allows Markdown, though reStructuredText remains the native format and most examples use it.

Carrd: Can I create multi-page websites with Carrd?

No. Carrd is designed for single-page sites only. For multi-page websites, you would need to use a full website builder like Webflow or Squarespace.

Source
Sphinx: Why do large projects choose Sphinx?

Automatic cross-referencing and API extraction from docstrings, which lighter generators do not provide.
