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 use CloudFlare a lot for "self hosting" .. but I also run an old pi from home with Bun in place of workers. Suprisingly compatible and low lift.
Not exactly "without CloudFlare", but for true compat you can probably also self host workerd itself which is open source: github.com/cloudflare/workerd
Fwiw if you want a simple pastebin, I've been running pinnwand for a couple years without any issues off of a single short docker compose file, I think running it on host also shouldn't be complicated

Thanks for checking the project out!
