+You might want to provision namespace-based isolation for your browsers. But that could throw a wrench into Flatpak-based distribution.
+
+When distributing browsers through Flatpak, things get a bit...weird. Nesting sandboxes in Flatpak doesn't really work, since Flatpak forbids access to user namespaces.
+
+For Chromium, they worked around this by patching Chromium zygote process (the process that provisions sandboxes) to call a Flatpak supervisor to create additional sandboxes. This is called the "spawn strategy". Chromium uses a two-layer sandbox: layer-2 is a syscall allow-list and layer-1 is everything else. The only problem is that Flatpak's layer-1 sandboxes are more permissive than Chromium's native layer-1 sandboxes, so the Chromium Flatpak has weaker sandboxing.
+
+Firefox's sandboxing isn't entirely dependent on user namespaces, but it is weakened a bit without them; there's no "spawn strategy" implemented at the moment. More info is [on Bugzilla](https://bugzilla.mozilla.org/show_bug.cgi?id=1756236).
+
+Now, whether this matters is something I can't decide for you. My personal opinion is that Flatpak serves as a tool to package, deliver, and sandbox native applications; Web browsers are tools that deliver and sandbox Web applications. Distributing a browser through Flatpak is like distributing Flatpak itself through Flatpak. Web browsers are an _alternative_ to Flatpak; they have their own sandboxing and updating mechanisms.

 - Partially evaluated: [Infinity Search](https://infinitysearch.co): young, small index. It recently split into a paid offering with the main index and [Infinity Decentralized](https://infinitydecentralized.com/), the latter of which allows users to select from community-hosted crawlers. I managed to try it out before it became a paid offering, and it seemed decent; however, I wasn't able to run the tests listed in the "Methodology" section. Allows submitting URLs and sitemaps into a text box, no other work required.
