alt Hacker NewsYou can use the pmtiles:// protocol in Maplibre GL, requires protomaps.js and a few lines of setup [1]
My experience with it is ... ok. It works. But going directly to cloud storage (s3 in my case) is unpredictable latency and neither the browser nor most servers really cache HTTP range requests granularly, so every tile is another high-latency round trip. Not worth it - I ended up putting Martin tile server in front of it.
I assume someone could write a protomaps adapter in WASM with some smart caching? Until then, Standard GET requests are just easier to cache and perform much better in practice. The downside being you have to run a server or statically generate files.

For what it's worth I think latency/reliability varies a lot with provider. Bunny Storage has quite good latency in my experience (100-300ms) and their CDN supports Range caching (from my understanding Cloudflare does too they just limit the size of the file regardless of the Range)
I've had success with using a cache in front of my buckets for great performance. In my case I have raster tiles so they get turned into z/x/y tile filenames and a cloudflare worker pulls that from the full file and caches the result in the region.
