Blunders is my favorite devtool. We’re building a high-performance application and we have Blunders profiling enabled during development and in production.

I don’t think we would have been able to build this product without Blunders and I now hesitate to using languages that Blunders does not support.

What is a Profiler?

A profiler highlights which parts of a computer program uses the most resources, such as CPU and Memory. This helps developers improve the performance of the program, making it faster and more reliable.

Blunders makes it easy to continuously profile large amounts of applications in production. This lets you immediately see what happened 3 days ago, instead of first trying to reproduce it locally.

How does Blunders work?

1Attach the Blunders Agent

Screenshot with the text java -javaagent:blunders-agent.jar -jar app.jar

Attach the Blunders agent your application. This can also be done programmatically.

2Notice spikes

Blunders highlights changes in behaviour of your application.

3Drill down

Shows how Blunders can visualise memory usage

Blunders lets you dig down into which code paths are allocating the most memory and using the most CPU.

Make understanding performance easy

Understand what your applications are doing in production, right now. Blunders provides easily accessible flame graphs that help you get to the bottom of your performance issues.

Invite team members to collaborate, all you need is a browser. Profiling is a great way to learn the codebase.
