The short version

  • Each has a real cost: Panda3D completely free to use including for commercial projects, with source code available under the permissive BSD license, no paid tier; 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: Panda3D covers 3D graphics rendering, Photon Engine covers Concurrent user billing.
  • Prices and features above were last checked on 30 August 2026.

Photon Engine

  • Adding multiplayer to a Unity game without hiring a network engineernot Panda3D
  • Competitive titles needing deterministic rollback rather than state synchronisationnot Panda3D
  • Games with a large but thinly spread player base, where concurrency stays low and per player pricing would cost morenot Panda3D
  • Training and simulation projects that need shared real-time state outside gamesnot Panda3D

Where each one falls short

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

Panda3D

  • Completely free to use including for commercial projects, with source code available under the permissive BSD license, no paid tier

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

Panda3D: Is Panda3D free to use?

Yes, Panda3D is completely free to use with no royalties, license payments, registration, or costs of any kind, even for commercial use.

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.

Panda3D: What license does Panda3D use?

Panda3D is distributed under a permissive BSD license, allowing users to study and modify the source code.

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.

Panda3D: Are there any costs for deploying Panda3D applications?

No, the SDK includes deployment tools at no additional charge and has no external paid dependencies required for deployment.

Source
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.
