Choosing between OpenKey by OpenKey and Zaplox Mobile Key App involves evaluating how each platform meets your hotel's operational goals and guest experience standards. Both serve to facilitate contactless, mobile-based access, but they differ significantly in features, integrations, and user feedback. OpenKey, with more recent reviews and higher ratings, currently stands as the more trusted solution. Your decision hinges on whether you prioritize extensive integrations and advanced management features or a quick-to-deploy, PMS-independent solution.
Both products aim to eliminate physical keys, reduce front desk congestion, and foster safer interactions, especially in a post-pandemic world. But while OpenKey offers a broader feature set and larger market presence, Zaplox emphasizes simplicity and speed of deployment without requiring system integration. How do these differences align with your hotel's needs?
OpenKey and Zaplox both solve the core problem of mobile key access, reducing guest contact points and streamlining check-in. OpenKey’s strength lies in its extensive integrations with over 50 PMS and lock providers, allowing for automation and centralized management. Zaplox, meanwhile, offers a quick setup by not requiring PMS integration, making it suitable for properties seeking rapid deployment without complex setup.
OpenKey’s higher overall ratings (4.26/5 vs 3.7/5) and larger review base (69 reviews vs 6) signal broader user confidence. Recent reviews reinforce this trend, with OpenKey users praising its reliability and feature depth, whereas Zaplox reviews tend to focus on ease and speed of implementation. Do you need a mature, feature-rich platform or a fast, straightforward solution?
If your hotel needs robust management tools, multi-property oversight, and extensive PMS integrations, go with OpenKey. It’s better suited for large or high-end hotels that require detailed control, guest communication features, and scalability. On the other hand, if your hotel prioritizes quick setup, low complexity, and standalone functionality, Zaplox provides a more straightforward, cost-effective option.
For independent hotels or properties with limited IT resources, Zaplox’s deployment simplicity can be a decisive advantage. Conversely, hotels with complex operations or multi-property portfolios will benefit from OpenKey’s advanced features and broader partner network.
OpenKey’s UI scores 4.45/5, with many users calling it intuitive and straightforward, supported by onboarding ratings of 4.22/5. Its app is praised for ease of use, integration, and guest communication features, though some users report occasional technical glitches. Customer support is rated 4.25/5, with quick responses noted—but some reviews mention delays in issue resolution.
Zaplox scores slightly lower on ease of use at 4.08/5, with reviews emphasizing its simplicity and fast deployment. Support receives a solid 4/5, but some users wish for more advanced features like lock battery status. Edge: OpenKey.
OpenKey offers 11 unique features, including keyless entry, notifications, multi-property management, guest dashboards, mobile check-in, and developer SDKs—features Zaplox does not provide. Zaplox’s key advantage is its standalone, PMS-independent operation, with a focus on contactless check-in and amenity access.
OpenKey’s extensive feature set caters to larger, more complex hotels needing detailed control and automation. Zaplox’s features focus on ease, speed, and basic mobile access, suitable for hotels seeking quick digital transformation. Edge: OpenKey.
OpenKey’s customer support is rated 4.25/5, with reviewers appreciating its responsiveness but noting some delays. Typical feedback highlights support as prompt but sometimes lacking in proactive communication or onboarding assistance.
Zaplox’s support scores 4/5, with reviews emphasizing its understanding of client needs and effective communication. Both platforms support contactless operations well, but OpenKey’s larger user base and more recent reviews suggest more current support experiences. Edge: OpenKey.
OpenKey boasts 34 verified partners, including major PMS and lock providers like SALTO, Infor, and RoomRaccoon. It offers deep integrations, enabling automation and streamlined management across multiple systems. Zaplox has 17 verified partners, including some overlaps with OpenKey, but fewer than OpenKey overall.
Shared partners include Stayntouch, SALTO, Oracle Hospitality, and Infor. OpenKey’s broader integration network supports scalable, complex hotel ecosystems better than Zaplox’s more limited set. Edge: OpenKey.
OpenKey’s overall rating of 4.26/5 is supported by 69 reviews, mostly recent, with a high likelihood to recommend (88%). Hoteliers in luxury and independent segments particularly favor it, citing improved operational efficiency and guest satisfaction.
Zaplox’s rating of 3.7/5 comes from only 6 reviews, with some praise for ease but limited recent feedback, making its score less reliable. Larger, more diverse properties tend to prefer OpenKey’s proven track record and review volume. Edge: OpenKey.
OpenKey charges a base price of $500, with no mention of monthly fees or implementation costs, suggesting straightforward pricing. Zaplox does not specify pricing but emphasizes its quick deployment without needing PMS integration, implying a likely lower or flexible cost structure.
Additional costs may arise if you choose advanced features or integrations, but OpenKey’s fixed fee simplifies budgeting. Zaplox’s lack of transparent pricing makes it harder to compare directly but could appeal to smaller hotels with tight budgets.

OpenKey and Zaplox both aim to modernize your hotel’s access, but their approaches differ significantly. OpenKey’s broader feature set and larger review base make it the more trusted option for hotels seeking comprehensive management and scalability. Zaplox offers a quick, simple deployment ideal for smaller properties or those just beginning their mobile access journey.
If your hotel values advanced features, integrations, and proven reliability, OpenKey is the clear choice. For properties that prioritize speed, ease, and cost-effectiveness with less complexity, Zaplox can serve as a solid entry point into mobile key technology.
In summary, opt for OpenKey if you need a mature, feature-rich platform with extensive support. Choose Zaplox if you want a fast, straightforward solution that can grow with your hotel’s needs over time.

How extensive is this company's reach and resourcing?
