The Decision

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?

Is OpenKey or Zaplox Better for Hotels?

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?

OpenKey vs Zaplox: Which Should Your Hotel Choose?

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.

Is OpenKey or Zaplox Easier to Use?

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.

Which Has Better Features: OpenKey or Zaplox?

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.

Which Has Better Customer Support: OpenKey or Zaplox?

  • Require extensive PMS integrations for automation.
  • Value detailed guest communication and management dashboards.
