Performance Monitoring Without Extra Tools or Registrations — How Important Is It?

Hi everyone! 👋

I’d like to raise an important topic that is often overlooked during development: performance monitoring for applications. We’re used to relying on powerful tools like Sentry, GlitchTip, and similar services. While they are great, what if you don’t want the extra complexity — registrations, external dashboards, or switching between multiple tools?

Wouldn’t it be more convenient to have something lightweight, that can be embedded directly into your code, giving you instant results? For example, simple monitoring powered by the native Performance API.

Here’s why this matters:

• Performance directly impacts user experience. If a page takes too long to load or the interface feels "laggy," users are likely to leave.
• Tools like Sentry are helpful in production, but during development, you often want immediate feedback without diving into external systems.
• Lightweight monitoring solutions can become part of your daily workflow without adding overhead.

Here’s the key question: How important is performance monitoring in your everyday development?

• Do you regularly track metrics during your work, or only when issues arise?
• How crucial is ease of setup? Would a simple, built-in solution be more effective than connecting complex tools?
• Should we monitor every task or just periodically check the overall performance picture?

I’ve created a lightweight solution that uses the native Performance API: perfomance-monitor. It’s perfect for local monitoring without third-party tools, registrations, or complex configurations. Feel free to try it out!

If you have examples, tools, or approaches you use for performance monitoring, please share them! I’d love to hear what works best for you in your day-to-day work.
