We use a variety of tools to make our docs site work. You could use these tools to build up your own docs site and - in most cases - do so for free or starting on a free tier.
Our content lives in a public GitHub repository, cloudflare-docs ↗︎.
GitHub offers a generous free tier ↗︎.
We use Cloudflare's AI Search as our search provider.
We used to use Algolia, which is also great for open-source docs because you can be part of the free DocSearch program ↗︎.
We use Nimbus ↗︎ for our docs, a documentation framework built on Astro ↗︎.
Nimbus's component registry ↗︎ and linting ↗︎ system have exponentially increased our site's capabilities (without much extra work).
We use GitHub Actions ↗︎ to build our site, which is then hosted on Cloudflare.
We are moving to Workers CI/CD, which currently runs in the background.
Both of these options include a free tier.
We host our content using Cloudflare Workers, specifically using their built in values for Astro sites
Workers offers a generous free tier.
We send analytics to multiple destinations using Cloudflare Zaraz, which has a generous free tier.
