The short version

  • Each has a real cost: Drupal steep learning curve: concepts that are implicit in WordPress are explicit and must be configured; Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
  • They diverge on capability: Drupal covers Structured content modelling, Sphinx covers Cross-references.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Drupal

  • Steep learning curve: concepts that are implicit in WordPress are explicit and must be configured
  • Smaller developer pool than WordPress, and correspondingly higher build costs
  • Major version upgrades have historically been substantial projects, not routine updates
  • Considerably more machinery than a straightforward marketing site needs

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

Answered from the vendors’ own pages

Drupal: Is Drupal free?

Yes, open source under the GPL. Costs are hosting, development and any commercial modules.

Sphinx: Is Sphinx free?

Yes, open source under the BSD licence.

Drupal: Drupal or WordPress?

WordPress is faster to launch, cheaper to staff and has a much larger plugin ecosystem. Drupal is stronger when the content model is genuinely complex and permissions are strict, which is why institutions favour it.

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.

Drupal: Why is Drupal common in government and universities?

Structured content modelling, granular access control and multilingual support are core rather than bolted on, and those are exactly the requirements those sectors have.

Sphinx: Why do large projects choose Sphinx?

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