The short version

  • 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.; VitePress customising beyond the default theme options requires writing Vue components, so a team with no Vue experience hits a wall at the first design request and cannot resolve it with configuration.
  • They diverge on capability: Outline covers Structured collections, VitePress covers Vite dev server.
  • Prices and features above were last checked on 31 August 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.

VitePress

  • Customising beyond the default theme options requires writing Vue components, so a team with no Vue experience hits a wall at the first design request and cannot resolve it with configuration.
  • There is no built in documentation versioning, so shipping docs for multiple released versions of a product means running separate builds or deploying separate sites and wiring the switcher yourself.
  • Like every git based generator it offers no editing interface, so writers and support staff who spot an error cannot fix it without a developer workflow.
  • The default local search builds its index in the browser at load time, so very large sites see a memory and startup cost on the reader side that Algolia would not impose.
  • The plugin ecosystem is small compared with Docusaurus, so features such as blogging, tag pages or client side redirects are often hand built rather than installed.

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.

VitePress: Do I have to know Vue?

Not to write Markdown pages. Yes, as soon as you want to change the theme or add an interactive component.

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.

VitePress: Does it handle versioned documentation?

Not natively. You build and deploy each version separately and link between them.

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.

VitePress: Is search free?

Yes, the built in local search is free and needs no service. Algolia DocSearch is supported if you prefer hosted search.

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.

VitePress: How does it compare on build speed?

Development start time stays roughly flat as pages are added because Vite does not bundle in development. Production builds still scale with page count.

VitePress: Can non developers contribute?

Only through the git hosting web editor, which still means a commit and a pull request.
