The short version
- Each has a real cost: Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration; 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: Read the Docs covers Build on commit, Starlight covers File based routing.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle
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
Read the Docs: Is Read the Docs free?
Free for open-source public projects. Private documentation requires a paid business plan.
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.
Read the Docs: What does it build from?
Most commonly Sphinx or MkDocs sources kept in your repository.
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.
Read the Docs: How does versioning work?
It maps branches and tags to documentation versions, so several releases are served side by side without manual work.
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.
