Blackfire.io vs packtracker: What are the differences?

What is Blackfire.io? Blackfire Profiler automatically instruments your code to gather data about consumed server resources like memory, CPU time, and I/O. Blackfire achieves a new level of accuracy by aggregating several profile samples and getting rid of non relevant data. Get even deeper and review the interactions with your entire stack (SQL database engines, cache servers, ...).

What is packtracker? Analyze your webpack bundle, on every commit. Check your webpack bundle size on every pull request. Track your webpack bundle size and composition over time and use that data to optimize your individual assets. Catch webpack bundle bloat before your users do.

Blackfire.io and packtracker belong to "Performance Monitoring" category of the tech stack.

Some of the features offered by Blackfire.io are:

• Profile a page at a mouse click thanks to the Blackfire web browser extension
• Browse through the function calls and identify performance bottlenecks thanks to the Blackfire intuitive UI
