You don't need to be Stripe and have a full engineering team working on your doc to make it awesome.
Docusaurus is a content-centric static site generator based on Node.js and React. You can build a documentation site but also a blog, landing pages...
The idea is that you just write Markdown files, and we generate a great docs site for you. You can get started in 5 minutes, focusing on content, and later do more advanced customizations so that your docs are top-notch.
I like to compare Docusaurus to the Pareto principle: you only need 20% of the effort to get 80% of the result. Docusaurus is flexible so you can also decide to invest more and get a better result.
Full-featured: docs, blog, pages, plugins, themes, versioning, i18n, a11y, SEO...
It is based on MDX (Markdown + React), which can help make your docs interactive.
Some comparable tools: VuePress, MkDocs... I believe we do a better job than others: more features but also great flexibility. In particular you can deeply customize the UI so that your documentation site really respects respects your branding.
Docusaurus 2.0 has already been widely adopted by the community during the beta phase.
