The short version
- Only BookStack has a free tier, so it costs nothing to try first.
- Each has a real cost: BookStack there is no vendor-hosted option at all, so you own the server, TLS certificates, database backups and upgrades, or you pay a third-party host that has no support relationship with the project and no ability to fix a bug.; 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
- They diverge on capability: BookStack covers Shelves, books, chapters, pages, Paligo covers Topic-based reuse.
- 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.
BookStack
- There is no vendor-hosted option at all, so you own the server, TLS certificates, database backups and upgrades, or you pay a third-party host that has no support relationship with the project and no ability to fix a bug.
- The shelf, book, chapter, page hierarchy is fixed at four levels and cannot be reshaped, so migrating a deeply nested Confluence or MediaWiki space means flattening content by hand and losing the original structure.
- It requires PHP and MySQL or MariaDB, which is a stack many engineering teams no longer run, so adopting it usually means introducing a database and runtime nobody else in the organisation maintains.
- Development is concentrated on a single maintainer, which makes the bus factor a legitimate procurement question for anything the organisation intends to depend on for a decade.
- Content lives in the database rather than in files under version control, so there is no docs-as-code workflow, no review by pull request and no branch per release.
- Export is per page, chapter or book, so moving a large instance to another platform means writing a script against the REST API rather than copying a directory of Markdown.
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

Answered from the vendors’ own pages
BookStack: Is there a paid or hosted version?
No. BookStack is MIT-licensed with no commercial edition and no official hosted service. Third-party hosts exist but are unaffiliated with the project.
Paligo: Is there a free tier?
No, Paligo has no published free plan; pricing starts at $15,000/year for the Business plan.
BookStack: Can I nest pages more deeply?
No. Four levels is the design, not a limitation waiting to be fixed, and content that needs deeper nesting has to be restructured.
Paligo: Are Nexus Portal and Nexus Answers included in the base licence?
No, they are separate products priced from $5,000/year and $6,000/year respectively.
BookStack: Does it support single sign-on?
Yes, through LDAP, SAML2 or OpenID Connect, with group to role mapping, and none of it is gated behind a paid tier because there is no paid tier.
Paligo: How is AI translation priced?
Through prepaid, non-expiring token packages (5M, 10M or 20M tokens) rather than a per-seat fee.
BookStack: How hard is it to migrate content in?
Straightforward for flat content through the REST API, awkward for deeply nested wikis, because the structure has to be collapsed to fit.
