The short version

  • Each has a real cost: 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.; Pygame licensed under GNU LGPL v2.1, free to use even in closed-source and commercial games, no paid tier
  • They diverge on capability: Photon Engine covers Concurrent user billing, Pygame covers Graphics rendering.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

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.

Pygame

  • Licensed under GNU LGPL v2.1, free to use even in closed-source and commercial games, no paid tier

Can I use Photon Engine for free?
Both have a free tier, so you can try either at no cost before committing.
What is Photon Engine best used for?
Photon Engine is most often used for adding multiplayer to a unity game without hiring a network engineer, competitive titles needing deterministic rollback rather than state synchronisation, games with a large but thinly spread player base, where concurrency stays low and per player pricing would cost more, training and simulation projects that need shared real-time state outside games. Of those, adding multiplayer to a unity game without hiring a network engineer and competitive titles needing deterministic rollback rather than state synchronisation are not what Pygame is typically brought in for.

Answered from the vendors’ own pages

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.

Pygame: How much does Pygame cost?

Pygame is free and open source software with no cost to use or distribute.

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.
