Good stack. strfry + Blossom + a web client is a common setup. These are the bits that tend to bite, from strfry's own docs:

- strfry only listens on localhost:7777 by default. Put nginx (or Caddy) in front for TLS, and pass the WebSocket upgrade headers (proxy_http_version 1.1, Upgrade, Connection "upgrade"). docs/DEPLOYMENT.md has a starter config.
- Set realIpHeader in strfry.conf (for example x-real-ip) and have nginx send it. It's empty by default, so behind a proxy every client shows up as 127.0.0.1 in logs and limits.
- Open files: strfry.conf tries nofiles = 524288. Check ulimit -Hn on the box (or LimitNOFILE in systemd) or it can fail to start or run out of sockets.
- The LMDB mapsize of 10 TB is virtual, not disk space. Don't panic when you see it.
- Decide early who can write. A public relay fills with spam fast. strfry write-policy plugins (docs/plugins.md) let you whitelist your own pubkeys.
- For Blossom behind nginx, raise client_max_body_size. nginx defaults to 1 MB, so photo and video uploads fail with 413 until you do.
- Back up the strfry DB folder and the Blossom blob store. A cheap VPS dying takes both.

Raspberry Pi works for a personal relay. LMDB likes an SSD more than an SD card.
