isPremiumName decides on every third-party login whether the player keeps their name, and none of its rules had a test that fails when the rule breaks: treating a 429 or 5xx from api.mojang.com as "free", swapping the free and taken TTLs, flipping the freshness comparison, answering "free" from an expired taken entry during an outage, or dropping the clear-at-4096 bound. Each of those leaves a squatter holding a name its owner has bought, or grows the cache without limit, with CI green. TestPremiumNameCache drives isPremiumName against a stub that answers with a fixed status and counts lookups, and seeds cache entries at chosen ages. Five mutants of handlers_hasjoined.go, one per rule above, each fail at least one subtest. It does not test an expired "free" entry during an outage; what that case should return is still open.

A Kubernetes-driven Minecraft server hosting platform — one command to deploy, automatic lifecycle, backup, and security.

Table of Contents
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
- 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.
- 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.
