The short version
- Only Sphinx has a free tier, so it costs nothing to try first.
- Each has a real cost: Paligo the Business plan starts at $15,000/year for only two authors, which is a high price floor compared with help-centre or wiki tools and prices out small documentation teams; Sphinx reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
- They diverge on capability: Paligo covers Topic-based reuse, Sphinx covers Cross-references.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Paligo
- The Business plan starts at $15,000/year for only two authors, which is a high price floor compared with help-centre or wiki tools and prices out small documentation teams
- Topic-based, structured authoring has a real learning curve for writers used to free-form documents or Markdown, and onboarding time should be budgeted separately from the licence
- Nexus Portal and Nexus Answers are separate paid products, so a buyer wanting hosted delivery or AI answers on top of authoring should expect additional annual cost beyond the base plan
- Storage is capped per author (10 GB on Business) with additional storage or authors priced as add-ons, so a growing team's costs are not fully captured by the headline per-author price
- Unlimited languages are only included on the Enterprise plan; Business is capped at two languages, which limits it for teams with more than a couple of target markets
- Migrating an existing large documentation set into Paligo's structured content model is a real project, not a data import, and that migration cost sits outside the subscription price
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
