23 Development Tools for Boosting Website Performance

Optimizing website performance can be challenging due to the numerous available tools. This article presents 23 performance analysis and optimization tools categorized for clarity. Some are well-known, others less so, but all are valuable assets for developers.

Key Takeaways:

• Client-side tools like Google's Test My Site, SiteSpeed.io, and Lighthouse measure and improve website speed.
• Code-level tools such as Dust Me Selectors, Penthouse, and Critical optimize website code for faster loading.
• Server-side tools including Apachetop, Ngxtop, and uptime-cli monitor web server performance and provide real-time metrics.
• SQL performance tools like Tuning-primer, MySQLTuner, and Mytop analyze and optimize MySQL server performance.
• Load testing tools such as Apache JMeter, Grinder, and Gatling assess website performance under load.

Client-Side Performance Tools:

1. Google's Test My Site: This online tool (powered by WebPageTest.org) assesses mobile speed using a Moto G4 on a 3G network, providing loading time, estimated lost visitors, industry comparisons, and optimization suggestions.

2. SiteSpeed.io: An open-source suite of tools (Coach, Browsertime, Chrome-HAR, PageXray) for measuring and improving website performance. Installable via npm or Docker.

3. Google Lighthouse: An open-source auditing tool integrated into Chrome DevTools, available as a Chrome extension or CLI tool. Essential for measuring and improving modern client-side app performance (especially PWAs).

4. Lightcrawler: Crawls websites and runs Lighthouse audits on each page. Installable via npm and configurable via JSON.

5. YSlow: A browser bookmarklet analyzing web pages and identifying performance bottlenecks based on Yahoo's best practices.

Server-Side Performance Tools:

14. Apachetop: A top-like tool monitoring Apache web server performance.

15. Ngxtop: A top-like tool parsing Nginx (and Apache) access logs and displaying key metrics.

16. uptime-cli: A CLI tool monitoring website uptime using the Uptime Robot API.

SQL Performance Tools:

17. Tuning-primer: A Bash script for MySQL performance tuning (version 5.5 ).

18. MySQLTuner: A Perl script analyzing MySQL server performance and providing configuration recommendations.

19. Mytop: A top-like tool displaying MySQL server performance metrics.

Load Testing Tools:

20. Apache JMeter: An open-source Java-based tool for load testing and performance measurement.

21. Grinder: A Java-based load testing framework for distributed load testing.

22. Gatling: A load testing tool using Scala and a DSL for scripting.

23. SQLBenchmarkPro: A cloud service for remote database performance monitoring.

This comprehensive list provides a strong foundation for tackling website performance challenges. Remember to consider the specific needs of your project when selecting tools.
