The short version

  • Each has a real cost: libGDX libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain; Photon Engine billing follows peak concurrent users, so a single stream or a launch weekend raises the bill immediately, and studios that cannot forecast concurrency cannot forecast the cost of their own launch.
  • They diverge on capability: libGDX covers Java language support, Photon Engine covers Concurrent user billing.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

libGDX

  • Publishing a Java game to desktop, Android, iOS and HTML5not Photon Engine
  • Rapid prototyping where an opinionated engine workflow is unwantednot Photon Engine

Photon Engine

  • Adding multiplayer to a Unity game without hiring a network engineernot libGDX
  • Competitive titles needing deterministic rollback rather than state synchronisationnot libGDX
  • Games with a large but thinly spread player base, where concurrency stays low and per player pricing would cost morenot libGDX
  • Training and simulation projects that need shared real-time state outside gamesnot libGDX

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

libGDX

  • libGDX is a Java framework built on OpenGL ES, so projects are tied to the JVM toolchain
  • Publishing targets are limited to Windows, macOS, Linux including Raspberry Pi, Android, iOS and HTML5
  • libGDX is a community-maintained Apache 2.0 project with no vendor and no paid support tier
  • libGDX ships as a framework rather than an editor, so there is no visual scene editor included

Photon Engine

  • Billing follows peak concurrent users, so a single stream or a launch weekend raises the bill immediately, and studios that cannot forecast concurrency cannot forecast the cost of their own launch.
  • Exceeding the band does not degrade gracefully; additional players are refused connections until concurrency falls or the plan is upgraded, which is a visible outage to your players at the worst possible moment.
  • PUN, the product most tutorials and courses still teach, is legacy, so a large share of the learning material available online points new projects at the wrong SDK.
  • Self-hosting is an enterprise arrangement rather than a purchasable licence, so a studio that wants its servers on its own infrastructure for cost or compliance reasons cannot simply buy that.
  • It is a networking layer only; accounts, persistence, leaderboards, inventories and anti-cheat all come from other services, so the multiplayer stack ends up as several vendors rather than one.

Answered from the vendors’ own pages

libGDX: Does libGDX cost anything?

libGDX is completely free and open source, licensed under Apache 2.0. There are no pricing tiers or costs.

Source
Photon Engine: What exactly is a concurrent user?

A player connected to Photon at that moment. Your plan is sized by the peak of that number, not by downloads, registered accounts or monthly actives.

libGDX: Can I use libGDX commercially?

Yes, libGDX's Apache 2.0 license permits commercial use at no cost. The license allows usage in both open-source and proprietary projects.

Source
Photon Engine: Which product should a new project use?

Fusion for most real-time games, Quantum where determinism matters such as fighting and competitive titles. PUN is legacy and should not start a new project despite the volume of tutorials.

Photon Engine: Does it work outside Unity?

Unity is the first-class target. Unreal and other engines are supported through Realtime SDKs with less coverage and slower feature parity.
