The short version

  • Only Slab 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; Slab it is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
  • They diverge on capability: Adobe RoboHelp covers Single-source publishing, Slab covers Topics instead of folders.
  • 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.

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

Slab

  • It is built for internal knowledge, so public product documentation on a custom domain with versioning is outside what the product does.
  • There is no docs-as-code workflow, no git synchronisation and no markdown files on disk, so engineering-owned technical documentation ends up somewhere else anyway.
  • Hierarchy is shallow by design, and organisations that genuinely need deep nested structure find topics an awkward substitute rather than an improvement.
  • There is no offline mode, so a knowledge base that includes incident runbooks is unavailable during exactly the incident where the network is the problem.
  • Pricing is per user per month, so organisations where most staff only read a handbook twice a year still pay a seat for each of them.

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.

Slab: Can I publish documentation publicly with Slab?

Posts can be shared by link, but it is not a product documentation platform. There is no custom domain publishing, versioning or API reference tooling.

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.

Slab: What does the free plan actually cover?

Up to ten users with unlimited posts and core integrations. It is a real free tier rather than a trial, and it is enough for a small company handbook.

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.

Slab: How does it compare with a general workspace tool?

Slab does less on purpose. There are no databases, boards or task views, which makes it faster to write in and much harder to turn into an unmaintained sprawl.

Slab: Does search really cover other tools?

Yes, connected sources are indexed and appear in results. That integration is the main reason to choose it, so verify your specific tools are supported before committing.
