Since Real User Monitoring first launched in 2015, Raygun has helped thousands of teams identify and resolve front-end performance bottlenecks impacting their customers. Today, we’re excited to announce support for first paint and first contentful paint, along with rich new visualizations designed to help you better identify and diagnose performance problems in your software.

Are you still thinking about last year’s software performance headaches? You aren’t alone. Even large-scale retail apps experience preventable problems like broken payment buttons, and every year we hear of another retail giant that is unable to cope with traffic spikes on Black Friday – a $3 billion e-commerce day. Luckily, many of these software problems can be prevented. We’ve put together a few tips for maintaining performant retail apps so you can be ready for anything.

Raygun’s Launch Notes are your regular round-up of all the improvements we made to Raygun last month — from major features to performance updates. With the release of our new first paint and first contentful paint metrics for RUM, you’ll be able to get a more granular understanding of how users experience your application. We’ve already started the beta, and we will be releasing the feature in the next few weeks. Watch this space!

As a software developer, you might not be used to thinking about the memory usage of your applications. In today’s development world, memory is plentiful and usually quite fast. Odds are, the programming language you use doesn’t require you to allocate your own memory, or free it when you’re done. That doesn’t mean that you’re in the clear when it comes to memory leaks though. The reality is that memory leaks can strike any application in any language.

“Script error” is one of the most cryptic error messages you may encounter. The main grievance is it provides no information about the actual cause of the problem. However, this secrecy is not a bug, but a feature that intends to protect your site from malicious attacks.
