Boundary vs Skylight: What are the differences?

Developers describe Boundary as "Real-time monitoring for server and applications with beatiful UI". Monitor it all: web servers, load balancers, application back-ends, big data clusters, queues, caching nodes, or databases. Boundary provides insights no matter what stack you use, whether you deploy in the cloud or your data center. On the other hand, Skylight is detailed as "The smart profiler for your Rails apps". Skylight is a smart profiler for your Rails apps that visualizes request performance across all of your servers.

Boundary and Skylight can be primarily classified as "Performance Monitoring" tools.

Some of the features offered by Boundary are:

• Monitor Servers and Applications in real-time
• Generate Alarms
• Customizable Dashboards

On the other hand, Skylight provides the following key features:

• Skylight looks at how your code is behaving in production, alerting you to improvements you can make before they become showstoppers.
• Skylight tells you exactly how your app is spending its time where it matters most—in your production environment
• Pricing starts at $20 for the first million requests, with automatic discounts for high-volume customers

"Great Visualization" is the primary reason why developers consider Boundary over the competitors, whereas "Beautiful UI" was stated as the key factor in picking Skylight.
