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.; Unity unity Personal is free only for businesses with under $200,000 in funding or annual revenue; above that a Pro subscription is required
  • They diverge on capability: Photon Engine covers Concurrent user billing, Unity covers Visual editor.
  • 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.

Unity

  • Unity Personal is free only for businesses with under $200,000 in funding or annual revenue; above that a Pro subscription is required
  • Unity Pro costs $210.00 per month or $2,310.00 per year per seat
  • Businesses with more than $25M in annual revenue are required to be on Unity Enterprise, which is custom priced and requires contacting sales
  • Deploying to game consoles and to Apple Vision Pro requires Unity Pro or above
  • Splash screen customization is not available on Unity Personal
  • Unity Personal is licensed for gaming and entertainment applications only
  • Read-only engine source code access is an Enterprise feature and carries an additional cost
  • Asset Manager storage on Personal is capped at 10 GB per organization
  • Unity AI tools are free for a 14 day trial on Personal, after which a paid subscription is required
  • Enterprise terms note that minimum subscription or spending commitments may apply

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.

Unity: How much does Unity Plus or Pro cost?

Unity's homepage shows a price placeholder but does not disclose actual subscription rates. Detailed pricing tiers must be accessed through the dedicated pricing section.

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.
