BuildABrowser is a browser and its rendering engine, both written in Java (as well as the parsers and layout algorithms).
It is available for Linux and Windows, and also has an experimental Android Desktop port.
I've had a lot of previous browser attempts (dating back to 2018 - I can give the link to my first ever attempt if you want),
but over time I've learned a lot, and my current attempt has been much easier to maintain and make progress on.
It implements layout algorithms (inline/block, flexbox, and grid (but not subgrid)) from scratch, and it passes Acid2.
It also supports positioning, floats, a number of pseudo-selectors (like :nth-child and :has), very simple media queries, and CSS layers.
It also has forms and cookies (but is not yet hardened for security) and also a tool for viewing the DOM and box tree.
On Linux, you can use -a11y accesskit to enable the experimental a11y layer that uses a fork of accesskit.
BuildABrowser only supports pages that don't require scripting at this time, and is very early stage, but I would say that quite a few pages do work well.
