Questions and answers

What is the best open source software for a gaming community?

For a gaming community, a self-hosted stack starts with Pterodactyl for game servers, Mumble for voice and chat and Discourse for forums. Each pick was chosen by hand for its job and is shown with GitHub data from October 2026.

Is there a self-hosted Discord alternative?

Yes. Stoat, Fluxer, Element (Matrix) and Rocket.Chat cover text chat, and Mumble covers low-latency voice. See the Discord alternatives page for the full list.

Is Pterodactyl free?

Yes. Pterodactyl is open-source software released under the MIT license, so you can self-host it at no cost. You only pay for the server it runs on, and some projects also offer an optional paid cloud plan.

Can I run this stack with Docker?

11 of the 16 apps here publish Docker images, including Pterodactyl, Pelican Panel and Stoat, so most of the stack can run side by side with Docker Compose on one server. Size the server for the heaviest app and add off-site backups.
