flyemoji 1976fca809 fix(nano): always relay properties as an array
sessionProfile tagged properties with omitempty, so an upstream answer
of "properties": [] (or null, or no key at all) reached Velocity with
no properties key. A Yggdrasil root may legitimately answer that way for
a player without a skin. Velocity 3.5.1's GameProfile deserializer
passes the missing key on as null and ImmutableList.copyOf throws, so
that player hangs at login with nothing logged, even though the same
answer sent straight to Velocity is accepted. Mojang always sends
textures, which is why the premium path and the hardware runs never hit
it.

Drop omitempty and replace a nil slice with an empty one before the
response is written. Removing omitempty alone is not enough: a nil
slice marshals as null, which Velocity rejects the same way.

The new subtest feeds the relay [], null and a missing key and expects
"properties":[] every time. The previous handler fails all three.

Features

  • Wake on Join: Servers start automatically when a player connects, and stop when idle — like hibernate for your server.
  • Web Dashboard: Monitor server status, online players, and resource usage from your browser, with backup and restore management.
  • Auto Backup & Restore: Scheduled world backups with one-click rollback from any backup point.
  • World Reaper: Worlds idle for more than 15 days are automatically backed up and removed to free disk space.
  • Multi-core Support: Compatible with Paper, Fabric, Forge, and NeoForge, federated behind a Velocity proxy.
  • Modpack Submission: Players submit custom modpacks; admin approval triggers automatic build and deployment.
  • Passkey Login: Passwordless authentication via fingerprint, face recognition, or hardware security keys.
  • Zero Trust Security: Panel traffic protected by Cloudflare Access; the internal API is never exposed to the internet.

Getting Started

On a prepared Linux host, run:

curl -fsSL https://raw.githubusercontent.com/MliroLirrorsIngenuity/Felis/main/deploy/bootstrap.sh | sudo bash

The script installs K3s, deploys the control plane, and launches a setup wizard. Once done, open your browser at the configured domain.

Build from Source

Felis is built with Go and Node.js:

# Backend (Go 1.26+)
go build -o felis ./cmd/felis

# Frontend (Node.js 22+)
cd panel
npm ci
npm run build

# Docker image
docker build -t felis:custom .

License Notes

  1. Derivative works are AGPL too: Any distribution of this project or of software derived from it must be released under AGPL-3.0 and must include the original copyright notice and license statement.
  2. Running it as a network service also triggers the source obligation (AGPL section 13): if you host a modified Felis for other people to use, you must offer those users the complete source of your modified version — even if you never distribute a binary. This is the one substantive difference between AGPL and GPL, and since Felis is a hosting platform reached over a network, it will essentially always apply.
