flyemoji 9ee8c48fff docs(openapi): list every answer hasjoined gives
The hasJoined contract listed only 200 and 204 and named authlib as
the caller. The handler now answers four more ways, and a proxy
operator reading the contract could not tell a refused login from a
down source.

- 204 also covers a missing or oversized parameter (no source is
  asked), a third-party name that is not a legal Minecraft username,
  and an identity id that does not parse.
- 400 for a request that declares a body. There is no response body,
  and the connection is closed.
- 500 when the bar-list lookup fails, with the usual error body.
- 503 when no source validated and at least one failed, since that
  source's player may be the one logging in.

The three query parameters now carry the 64-byte cap. The profile name
says a third-party player holding a registered Mojang name gets it
back prefixed and cut to 16 characters. The description names
Velocity, drops the "thin login hook" that does not exist, and says
that a non-200, non-204 answer makes Velocity report the auth servers
as down.

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.
