it doesn't right now, but the fallback feature is planned for in a future release. mostly because there's no simple way to handle the classic fallbacks like aws, gcp and azure, and we wanted to spend some time thinking about their DX.
Right now, some things are somewhat hard-coded to be Cloudflare compatible. If someone's willing, you can just deploy this without Cloudflare, but you'd need to dig into the code a little.
In the future releases, I'll make it possible to host it on VPCs and release a Dockerfile along with it, so that should help a little.
I couldn't find the right words to describe this, in comparison to something like Github Gist. I suppose "Own-your-data" since the D1 db generated is yours completely.
Happy to change the branding to be more reflective of this!
This is pretty cool~ Thanks for suggesting this, I will read this in detail and add it to the next (0.5.0) release of memchunk.
