Build me a clean, easy to browse lookup site for Google internal technologies and their closest real world equivalents.

I want it to feel like a practical cheat sheet for ex Googlers, with sections for core technology, infrastructure, storage, services, and any other categories from the notes. Let people quickly search or filter by Google internal name, external product, or open source alternative, then click through to the relevant docs. Keep the design simple and readable, like a reference tool instead of a marketing site.

Please preserve the spirit of the README, especially that this is a public, non confidential mapping and that pull requests should be easy to add. If it helps, make the table data easy to update from markdown so new entries can be added without much effort. Use current docs online if you need to confirm links or names.
