Bonus Tip for 2026
Don't just hoard plugins. Each active extension adds memory overhead. We recommend auditing your extensions every month. For one-off tasks like regex testing or JSON formatting, rely on fast, client-side web utilities rather than installing heavy IDE plugins.
Pair Your IDE with Browser Tools
Many VS Code tasks can also be done instantly in the browser. Our JSON Formatter, Regex Tester, and Diff Checker run entirely client-side, giving you zero-latency results directly alongside your code editor.
