The short version

  • Only Starlight 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; Starlight there is no editing interface, so every correction requires a git client, a Node install and a CI run, which puts documentation changes out of reach for anyone who does not already work in a repository.
  • They diverge on capability: Adobe RoboHelp covers Single-source publishing, Starlight covers File based routing.
  • 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 Starlight
  • A team migrating off an older perpetual RoboHelp licence that needs to evaluate the new subscription cost against continued use of the old versionnot Starlight
  • A documentation team wanting a lower entry price than MadCap Flare for comparable single-source, multi-format publishingnot Starlight
  • A writer producing responsive HTML5 help output as the primary deliverable rather than PDF or print documentationnot Starlight

Starlight

  • A developer tool whose docs live in the same repository as the code and are reviewed in the same pull requestnot Adobe RoboHelp
  • A team that already runs Astro for its marketing site and wants one build pipeline for bothnot Adobe RoboHelp
  • Documentation that must be served from a CDN or an air gapped static host with no search backendnot Adobe RoboHelp
  • A multilingual open source project that needs per locale content trees and untranslated page fallbacknot 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

Starlight

  • There is no editing interface, so every correction requires a git client, a Node install and a CI run, which puts documentation changes out of reach for anyone who does not already work in a repository.
  • Starlight versions track Astro versions, so an Astro major release becomes a documentation site migration on someone else timeline rather than yours.
  • Pagefind builds the whole search index at compile time, so build duration and index size grow with page count and large documentation sets pay for it on every deploy.
  • There is no analytics, no feedback widget and no page level rating built in, so measuring which pages fail readers means wiring a third party script yourself.
  • Component overrides are limited to the slots the theme exposes, and anything outside those slots means forking the theme and inheriting the merge burden on every upgrade.

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.

Starlight: Can a non technical writer publish a page without help?

No. There is no content management interface. Every change is a commit, a pull request and a build.

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.

Starlight: Do I need to know Astro to use it?

Not for basic use. Markdown files and a config file are enough until you want custom components, at which point Astro knowledge becomes mandatory.

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.

Starlight: Is search included or do I pay for it?

Included and free. Pagefind builds a static index at compile time. Algolia DocSearch is optional if you want hosted search instead.

Starlight: What happens when Astro releases a major version?

Starlight follows it, and your site needs a migration. Read the upgrade guide before pinning a version for a long lived project.

Starlight: Can I self host with no external services?

Yes. The output is static HTML, CSS and a search index. Nothing calls out at runtime unless you add it.
