The short version

  • Only Outline has a free tier, so it costs nothing to try first.
  • Each has a real cost: Adobe RoboHelp roboHelp is now subscription-only through Adobe, so a team that previously owned a perpetual licence faces an ongoing cost that did not exist under the older purchase model; 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.
  • They diverge on capability: Adobe RoboHelp covers Single-source publishing, Outline covers Structured collections.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Adobe RoboHelp

  • A technical writing team already using other Adobe products wanting help authoring inside the same vendor relationshipnot Outline
  • A team migrating off an older perpetual RoboHelp licence that needs to evaluate the new subscription cost against continued use of the old versionnot Outline
  • A documentation team wanting a lower entry price than MadCap Flare for comparable single-source, multi-format publishingnot Outline
  • A writer producing responsive HTML5 help output as the primary deliverable rather than PDF or print documentationnot Outline

Outline

  • Running an internal wiki on your own infrastructure when documentation cannot leave a specific jurisdictionnot Adobe RoboHelp
  • Replacing a general-purpose workspace tool with something narrower where search speed and writing flow matter mostnot Adobe RoboHelp
  • Keeping engineering decision records and postmortems in templated documents that link to each other automaticallynot Adobe RoboHelp
  • Giving a company already standardised on Google or Okta a wiki that inherits identity and group membership directlynot Adobe RoboHelp

Where each one falls short

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

Adobe RoboHelp

  • RoboHelp is now subscription-only through Adobe, so a team that previously owned a perpetual licence faces an ongoing cost that did not exist under the older purchase model
  • The product has changed hands between several owners over its history before landing at Adobe, and buyers should not assume the same version-to-version continuity or community size as a single-vendor product like Flare
  • Pricing seen by a given buyer can vary depending on purchase channel and reseller, so the $29.99/month figure should be confirmed directly on Adobe's own site before budgeting
  • Deep integration value is realised mainly by teams already inside the Adobe ecosystem; a team with no other Adobe products gets less differentiated benefit from that integration
  • Windows-centric desktop authoring limits teams standardised on macOS or Linux to whatever web-based capability Adobe offers, which may lag the desktop feature set
  • As with any single-source authoring tool, migrating an existing large documentation set into RoboHelp's structure is a real project cost not captured in the subscription price

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.

Answered from the vendors’ own pages

Adobe RoboHelp: Is RoboHelp still sold as a perpetual licence?

No, current purchasing is through Adobe's subscription model rather than a one-time perpetual licence.

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.

Adobe RoboHelp: What is the entry price?

Adobe lists RoboHelp at around $29.99 per month per user with an annual commitment; reseller pricing may vary.

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.

Adobe RoboHelp: Does RoboHelp integrate with other Adobe products?

Yes, it is positioned within Adobe's Document Cloud family alongside tools like Adobe Experience Manager.

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.

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.
