WordPress Plugin Risk Assessment Checklist
Plugins add power to WordPress, but every plugin also adds code, database queries, permissions and security risk. This checklist helps you decide whether a plugin is safe enough to install, keep or remove.
Core principle
A plugin is not free just because it costs no money. It can cost performance, security, compatibility and maintenance time.
Checklist
- Define why the plugin is needed.
- Check whether the feature can be done without a plugin.
- Check update history.
- Check compatibility with your WordPress and PHP version.
- Check number of active installations and reputation.
- Check whether the plugin touches login, database, payments or user data.
- Avoid nulled or modified premium plugins.
- Backup before installing.
- Test frontend and wp-admin after activation.
- Remove plugins that are inactive, duplicated or no longer needed.
Reusable rule
Keep the plugin stack small. Fewer plugins mean fewer update conflicts, fewer attack surfaces and easier troubleshooting.
When to Use This Checklist
Use this checklist before installing, updating or keeping a WordPress plugin on a production website.
