Starlight versus Docusaurus
Compare	Starlight	Docusaurus
Verdict	Worth it	Depends
Best for	Engineering teams shipping product docs	Developer-facing product docs
Who it's not for	Non-technical writers . it's code-first, not WYSIWYG	Non-technical writers without JS/React skills
Privacy	Official security page exists; dependency scans show 2 medium-severity vulnerabilities (max 5.3) in the npm package.^⁵	No known core vulnerabilities in reviewed sources; 2025 CVE-2025-53624 hit a third-party gists plugin, exposing GitHub tokens.¹⁴
Support quality	No support-quality evidence in sources	Community support via GitHub; no vendor SLA.
Public sentiment	Direct user reviews are scarce in sources; one engineering team publicly switched its docs from Docusaurus to Starlight.^¹	Users call it the leading free docs generator; complaints center on build performance at scale and the technical setup.^⁹
Biggest gotcha	Guess: open-source means DIY hosting, upgrades, and no vendor to call^³	Vet third-party plugins: a gists plugin leaked GitHub tokens (CVE-2025-53624).¹⁴
