The short version

  • Only Outline has a free tier, so it costs nothing to try first.
  • Each has a real cost: Outline the Business Source Licence is not an open source licence, so anyone planning to host Outline for clients, resell it or embed it in a commercial service is prohibited until the per-release change date passes, and this is regularly discovered only at legal review.; 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: Outline covers Structured collections, 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.

Outline

  • The Business Source Licence is not an open source licence, so anyone planning to host Outline for clients, resell it or embed it in a commercial service is prohibited until the per-release change date passes, and this is regularly discovered only at legal review.
  • There is no local password authentication, so self-hosting requires an identity provider to be in place first, which turns a small internal wiki into a project with a dependency on Google, Okta, Entra or a Keycloak instance somebody has to run.
  • Self-hosting needs Postgres, Redis and S3-compatible object storage together, so the operational footprint is larger than the single database most internal wikis require.
  • The hosted plans offer no customer-selectable hosting region, so buyers with data residency obligations are pushed to self-hosting even when they would have paid to avoid running servers.
  • It is built for internal knowledge rather than public documentation, with no versioned documentation sets, no static output and limited public publishing, so it will not serve as a product documentation site.
  • Because it is a single-vendor project rather than a foundation-governed one, a future licence or pricing change applies to new releases and the only defence is staying on an older version.

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

Outline: Is Outline open source?

No, not in the OSI sense. It is source available under the Business Source Licence, which permits internal use and self-hosting but not offering it as a service to others, with each release converting to an open source licence after its change date.

Paligo: Is there a free tier?

No, Paligo has no published free plan; pricing starts at $15,000/year for the Business plan.

Outline: Can I run it for free?

Yes, for your own organisation. Self-hosting carries no licence fee, only the cost of running Postgres, Redis, object storage and an identity provider.

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.

Outline: Can I choose where the hosted version stores data?

No. The hosted plans do not offer a region choice, so residency requirements mean self-hosting.

Paligo: How is AI translation priced?

Through prepaid, non-expiring token packages (5M, 10M or 20M tokens) rather than a per-seat fee.

Outline: Does it work for public product documentation?

Poorly. It has no versioned documentation sets or static site output, so it is best kept for internal knowledge.
