Photon Realtime

Photon Realtime is a hosted client-server networking service for cross-platform multiplayer games. It is best suited to developers who want managed matchmaking and room-based play, rather than the work of hosting the networking layer themselves. Its flexible session and connection options are useful, but production pricing can become substantial once a project needs more than a small fixed user allowance.

Overview

Realtime lets developers match players randomly, search for rooms by parameters, or let players choose from open rooms. It supports synchronous and asynchronous turn-based play, and players can rejoin rooms after disconnection. That combination fits games built around sessions and recoverable turns; it is less compelling if a team does not need room-based matchmaking or wants to operate its own networking infrastructure.

Photon Cloud hosts applications across global regions and is designed to scale from a handful of users to tens of thousands of concurrent users. HTTP webhooks can persist player and room data, properties, and event-cache contents to Photon Cloud or the developer’s own storage. This gives teams a route to retain session state without tying persistence to one storage destination.

Key features

• Room matchmaking: Random matching, parameter searches, and open-room selection cover several ways to form a session, without requiring every game to use the same player-discovery flow.
• Disconnection recovery: Room rejoin and synchronous or asynchronous turn-based modes suit games where a session must survive interruptions or proceed at different paces.
• Persistence hooks: Webhooks can retain player data, room data, properties, and event-cache contents, either in Photon Cloud or developer-owned storage.
• Transport choice: Client connections can use Reliable UDP, TCP, HTTP, or WebSockets. This range helps teams accommodate different connection requirements, though the right option depends on the game and client.
• External authentication: Supported providers include Epic EOS, Facebook, Oculus, Steam, and VIVEPORT, alongside custom authentication. That is useful for games already using those identity systems.
• SDK coverage: Documented Realtime SDK variants include Unity and .NET, while Photon SDK downloads also include JavaScript and native platform packages. The .NET Realtime SDK is tested only for Windows applications; Unity’s stated platform range includes Windows, macOS, Linux, Android, iOS, consoles, and XR devices.

Photon Engine says it is ISO 27001:2022 certified and aligned with GDPR and CCPA, and that Photon Cloud does not store personally identifiable information. Enterprise Cloud adds dedicated servers, service-level guarantees, priority operations support, server plug-ins, and multi-layered DDoS protection. These are meaningful provisions for larger deployments, but Enterprise Cloud is a different cost and support tier from the fixed-allowance plans.

Pricing

Realtime is freemium, but its free tier is explicitly for development, not a live game launch. Plan choice determines both concurrent-user capacity and monthly traffic allowance; the fixed plans also distinguish between burst capacity and games-only use.

Plan	Price and terms	Allowance and fit
Development Only — 20 CCU	free	20 concurrent users, 60.0 GB traffic/month, development only, no CCU burst. Suitable for development, not production.
100 CCU	$95, paid once, billed for 12 months	100 concurrent users and 0.3 TB traffic/month; games only, no CCU burst. Its annual billing term and small capacity make it a narrow production allowance.
500 CCU	$95 a month, billed per month	500 concurrent users and 1.5 TB traffic/month, with CCU burst; games only. It offers more headroom than the 100 CCU option at the same stated price, but the 100 CCU price is for a 12-month term.
1000 CCU	$185 a month, billed per month	1,000 concurrent users and 3.0 TB traffic/month, with CCU burst; games only. A step up for games whose expected peaks exceed the smaller caps.
2000 CCU	$370 a month, billed per month	2,000 concurrent users and 6.0 TB traffic/month, with CCU burst; games only. It provides the largest fixed allowance among these plans, but still sets a defined ceiling.
Premium Cloud	$0.29 a month, billed per CCU and invoiced based on monthly usage; $580 minimum fee per month	2,000 CCU minimum, 6.0 TB traffic included, usage-based CCU auto-scaling, DDoS protected by default. It suits deployments that need scaling, but the minimum fee and starting capacity make it unsuitable for small projects.
Enterprise Cloud	Custom pricing	Dedicated servers, unlimited titles, SLA, priority operations support, server-authoritative plug-ins, and multi-layered DDoS protection. A fit for organizations that need those operational and server-side provisions.

All plans include online documentation, samples, tutorials, videos, and help with account and billing issues; paid support options are described for higher tiers. The cheaper development plan gives up production use and burst capacity, while fixed paid plans cap concurrency and traffic. Teams should compare their forecast against both allowances before choosing a tier.

Platforms

Photon identifies supported platforms as Windows, macOS, Linux, Android, iOS, Web, PlayStation 4/5, Xbox One/Series, and Nintendo Switch. The Unity SDK also lists XR devices. Platform support is not uniform across SDKs: the Realtime .NET SDK is tested only for Windows applications, so cross-platform teams should account for that constraint when selecting an SDK.

Who it's for

Realtime is aimed at multiplayer developers from indie teams to AAA studios. It is a sensible fit for teams building room-based games that value hosted global-region infrastructure, flexible matchmaking, turn-based modes, rejoin behavior, or webhook-based persistence. The development tier gives small teams a way to build within a defined 20-user and 60.0 GB monthly traffic cap.

It is a weaker fit for a live game that must remain free, needs uncapped concurrency without a minimum commitment, or cannot work within the chosen plan’s user and traffic limits. Larger teams may find the Premium Cloud minimum or the custom-priced Enterprise tier more appropriate, depending on whether they need usage-based scaling or dedicated operational provisions.

Pros and cons

• Pro: Several matchmaking paths and room rejoin support give developers control over how sessions form and recover.
• Pro: Webhooks can persist multiple kinds of room and player state to Photon Cloud or a developer’s own storage.
• Pro: Reliable UDP, TCP, HTTP, and WebSockets provide transport choices, while external and custom authentication accommodate different account setups.
• Con: The free plan is development-only and capped at 20 concurrent users, 60.0 GB per month, with no burst capacity.
• Con: Paid fixed tiers impose user and traffic ceilings, and Premium Cloud starts at a $580 minimum fee per month with a 2,000 CCU minimum.
• Con: SDK platform coverage differs: the Realtime .NET SDK is tested only for Windows applications.

Alternatives

Compare other options in Game Networking Middleware and Game Matchmaking Software. Consider Photon Fusion if its free plan’s one-app limit, games-only use, approximate 40k MAU, and 0.3 TB monthly traffic allowance better fit the project. Photon Quantum is another Photon option with a free development plan for 20 connected users and 60.0 GB monthly traffic.

FishNet is worth considering for Unity projects seeking a free networking solution without CCU caps or CCU paywalls. Mirror Networking is a free, open-source MIT option with no paywalls or CCU costs, while Netick offers free server-authoritative state-sync networking for Unity, with Interest Management and Lag Compensation reserved for Pro.

Normcore may suit teams that want unlimited applications, concurrent users, and rooms on its Public plan, subject to 100 room hours. SmartFoxServer is another freemium alternative with a free Community Edition. Colyseus offers an open-source option that can be self-hosted on a developer’s own servers, with community support and no restrictions.

Verdict

Choose Photon Realtime for a room-based multiplayer game that needs hosted matchmaking, disconnection recovery, persistence hooks, and multiple transport or authentication options. Its strongest case is the breadth of managed networking features and global-region hosting; its clearest drawback is the cost structure, from a development-only free tier to production allowances, a $580 Premium Cloud monthly minimum, or custom-priced Enterprise Cloud. Look elsewhere if the project needs production hosting without defined caps or a minimum fee.
