Access Subscription

The Access subscription is needed to access Quantum's SDKs, the online documentation and exclusive support via Discord. The included CCU are for one app only and cannot be combined with other plans or split-up across different apps.


A seat represents a single user license allowing to use Quantum. Multiple seats allow users to work together on projects Each seat is directly assigned to a specific Photon user account and cannot be shared inside an organization.

Concurrent Users (CCU)

The number of users allowed to connect to your application is defined by its CCU. For plans the CCU total is defined by the sum of peaks for all regions.

Sample Month: EU peak 420 CCU, US peak 230 CCU, Other regions 0 CCU — CCU total = 420 + 230 = 650, matching 1000 CCU subscription plan.

CCU Burst, Overage

Don't worry about losing users - we allow you to temporarily burst your agreed CCU limit and will simply bill this CCU overage with next month's invoice according to the fees set out in your subscription agreement. After your first burst you have 48 hours to upgrade your subscription plan before we, subject to our sole discretion, may cap your number of CCU to the agreed number.
For the CCU burst, the number of CCU is defined by the sum of CCU peaks over all connected regions.

Traffic Calculation

The included traffic depends on your subscription plan. All incoming and outgoing messages to the Photon Cloud servers count towards the traffic limit. Overage fees apply to traffic exceeding that limit - see table above.

Sample: 1000 CCU plan * 3 GB incl. per CCU = 3 TB included traffic.

Monthly Active Users (MAU)

We assume, as rule of thumb and based on our experience, 1 CCU to match 20 daily active users (DAU). Each DAU translates to 20 monthly actives (MAU).

One-Time Plans

One-time plans apply to one application and for 12 months, no recurring fees. You can add 100 CCU to any other existing monthly subscription plan, e.g. 100 + 500 = 600 CCU in total. Can be applied to an app only once at a time.


For optimum round-trip-times your application can connect the nearest region we host in. Choose from multiple regions around the globe.

Down- and Upgrade at any Time

Downgrade and upgrade subscription plans at any time. Additional CCU are available immediately. Any fees paid but unused will be credited automatically. Termination takes effect at the end of the month.

Peers per Room

Using Photon, users are connected to "Rooms" to play a multiplayer match, collaborate or communicate. "Peers per Room" represents the actual amount of connected game or application clients ("Peers") per Room at the same time.

Msg / Sec

Total inbound and outbound messages of all connected Peers (as counted by Photon) divided by the number of Photon Rooms. The more Peers are joining a room, the more Messages per Second ("Msg / Sec") will be sent around (N messages x M clients) and the amount of used traffic will be increased. Check our FAQ-page on how to calculate messages and traffic consumption for your app.

Support and SLAs

All packages include free forum access and e-mail support. Agreements with service levels, priority support are available on request.
