The code profiling instrument additionally sells these help and improve packages for builders trying to prolong or add help to their licenses:

  • Single license: $219
  • Floating license: $879
  • Tutorial single license: $109
  • Tutorial floating license: $369

Qualifying builders can apply for an open-source JProfiler license for non-profit initiatives.



Greatest for builders in search of a code profiler to research PHP utility efficiency and spot bottlenecks.

Xdebug is a well-liked PHP extension. It presents a number of options to reinforce the PHP growth expertise, together with debugging and profiling. With help from visualization instruments, Xdebug’s profiling will help builders analyze PHP utility efficiency and pinpoint bottlenecks.

Options of Xdebug

A few of Xdebug’s prime code profiling options embrace:

  • A number of profiling modes
  • Operate-level profiling
  • Reminiscence utilization profiling
  • A number of output codecs
  • Name graphs
  • Combination profiling knowledge

Xdebug presents a number of profiling modes, together with CPU, perform traces, and reminiscence utilization. Its function-level profiling particulars how a lot time is spent in every perform when a program is executed to identify efficiency bottlenecks, whereas its reminiscence utilization profiling spots inefficient reminiscence administration and reminiscence leaks in PHP functions.

Builders can generate profiling knowledge in a number of output codecs, together with Callgrind, HTML, and plain textual content, and so they can use the profiler’s name graphs to grasp how code interacts and the place efficiency issues could seem. Xdebug additionally presents profile aggregation. By aggregating profiling knowledge from varied requests, you may higher perceive how your PHP utility’s efficiency evolves in response to consumer interactions and circumstances.

Professionals of Xdebug

Xdebug’s profiling strengths embrace:

  • Open-source
  • Easy setup
  • Customization
  • Detailed knowledge

Xdebug’s standing as an open-source extension will possible be an enormous professional for builders in search of a free code profiler. Establishing Xdebug is easy, due to strong help and documentation guiding you all through the method. Builders can configure Xdebug to suit their customized profiling wants, and it additionally generates detailed profiling knowledge for pinpointing bottlenecks in efficiency, resembling reminiscence utilization, name graphs, execution instances, and extra.

Cons of Xdebug

Xdebug’s profiling weaknesses embrace:

  • Studying curve for freshmen
  • Primary options
  • PHP limitations

Whereas it presents a easy setup and may be configured to suit your customized wants, some builders new to profiling may have additional time to get snug with Xdebug. As a PHP extension with varied options outdoors of profiling, Xdebug could not appear as superior or in-depth as different devoted code profilers. One other Xdebug weak point is that it was created for PHP functions. Builders in search of profiling capabilities for different programming languages will subsequently should look elsewhere.

Pricing of Xdebug

Xdebug is a PHP extension that’s open-source and free to make use of. Whereas Xdebug prices nothing to obtain, set up, and use, it’s possible you’ll incur prices when utilizing the profiler instrument for any industrial IDEs (Visible Studio Code, PhpStorm, and so on.), superior help, premium merchandise, and companies.


Python tutorials

Greatest for Python builders trying to determine bottlenecks of their code and analyze utility efficiency.

cProfile is Python’s built-in code profiler. A part of the Python Normal Library, it measures how a lot time is spent on every perform and helps builders spot coding bottlenecks and analyze the efficiency of their Python functions.

Options of cProfile

cProfile’s prime options embrace:
