New PlayFab titles begin in this state. Use Evaluation Mode when you want to explore a PlayFab service and determine whether it meets your needs. When you're ready to move beyond exploration, transition out of Evaluation Mode to use production-scale capacity and features beyond Evaluation Mode limits. If your game is coming to XBOX, [link a qualifying Partner Center product](https://docs.xbox.com/services/playfab/identity/player-identity/platform-specific-authentication/xbox-live-add-on.md) to receive [XBOX Partner benefits](https://docs.xbox.com/services/playfab/get-started/foundation-benefits.md). These benefits include the foundational set of PlayFab services at no additional cost. Enable usage-based billing for additional paid features and capacity. ## Identify an Evaluation title Game Manager displays an **Evaluation** label on the title in the studio title list and within the title's navigation. You can also review the title's current limits in Game Manager. ## Evaluation Mode limits An Evaluation title is limited to 1,000 lifetime unique player accounts. The limit counts every player account ever created for the title; it isn't a monthly active-user or daily active-user limit. After the title reaches this limit, PlayFab rejects requests to create additional player accounts. > [!NOTE] > > As long as a title remains in Evaluation Mode, usage of services available in Evaluation Mode isn't counted toward its billable meters. The following example shows how PlayFab treats usage for two fictional titles: | Title | Billing state | Example PlayStream usage | Billing treatment | | - | - | -: | - | | Fun Game | Usage-based billing | 1,000,000 events | Charged according to the applicable [meter rate](https://docs.xbox.com/services/playfab/pricing/meters/meters.md) | | Fun Game 2: The Return of Fun | Evaluation Mode | 100,000 events | No usage charge while the title remains within Evaluation limits | This example illustrates billing treatment only. Both titles remain subject to service-specific limits and API rate limits. Evaluation titles also have service-specific operational and API limits. To view the current limits for a title, open the title in Game Manager and select **Settings** > **Limits**. For details about how API limits are applied, see [API rate limits](https://docs.xbox.com/services/playfab/live-service-management/service-gateway/throttling/what-is-throttling.md). Features that aren't available in Evaluation Mode, including CloudScript (classic), [Multiplayer Servers](https://docs.xbox.com/services/playfab/multiplayer/servers/index.md), Insights, automation and experimentation, and legacy APIs, aren't listed as allowances. Enable usage-based billing to access paid features and capacity. > [!NOTE] > > Requests to APIs that aren't available in Evaluation Mode return a permissions error and don't complete. ## Move beyond Evaluation Mode When you're ready to move beyond Evaluation limits, choose one or both of the following options: * **Enable usage-based billing.** Attach a payment instrument to the studio and turn on usage-based billing for the title. This allows the title to use paid PlayFab services and additional capacity, with usage charged according to the applicable [meters and rates](https://docs.xbox.com/services/playfab/pricing/meters/meters.md). There is no separate **Launch Title** step. * **Link an XBOX product.** If your game is coming to XBOX, [link its Partner Center product to the PlayFab title](https://docs.xbox.com/services/playfab/identity/player-identity/platform-specific-authentication/xbox-live-add-on.md). A qualifying linked title receives the foundational set of PlayFab services at no additional cost through [XBOX Partner benefits](https://docs.xbox.com/services/playfab/get-started/foundation-benefits.md). A payment instrument isn't required when the title uses only those included services. * **Use both.** An XBOX-linked title can also enable usage-based billing. The title receives its included XBOX Partner benefits, while paid features and usage outside those benefits are charged according to the applicable meters and rates. ## Frequently asked questions ### Do I need to launch the title in Game Manager?
