Admin Optimizer VS JSONLint

• Database Cleaner
  Schedule regular optimization and cleaning of the WP database to improve site performance. Pro adds options to manually clean individual DB tables, track unused options, and remove autoload bloat from the Options table.
• Heartbeat Control
  Modify the WordPress Heartbeat API interval to reduce server load and improve the editor experience.
• Disable Emojis
  Remove all emoji-related styles and scripts from the site.
• Block Failed Login
  Limit failed login attempts and block bad actors from carrying out brute-force attacks. Pro adds options to customise the lockout duration, a full lockout mode, and the ability to hide the login form during lockout.
• Two-Factor Authentication
  Enable two-factor authentication (TOTP) for all your users. Pro adds options to make 2FA compulsory for defined user roles, block users without 2FA from logging in, and allow users to save trusted devices.
• Custom Login URL
  Hide the wp-login.php URL and create a custom secret login URL for your users.
• Post Cloner
  Easily clone posts and any other post type, including all post meta and taxonomies.
• Content Refresh
  Easily keep your content updated for SEO. Clone a post as a draft child. When you (re)publish the clone it updates the original post — perfect for refreshing old content without creating a new URL.
• XML Sitemap
  Configure and manage the native WordPress XML sitemap for search engines. Pro adds sitemap caching for improved performance and a Google News sitemap.
• Limit Image upload size
  Set a maximum file size for image uploads to stop users from uploading oversized files.
• Custom Fields Builder
  Build a custom fields layout and create fields for any post type. Show or hide fields based on post type, post status, user role, and more.
• Disable Gutenberg Editor
  Disable the block editor and restore the Classic editor as the default.
• SMTP Email
  Replace the default WordPress mailer with an external SMTP service to ensure reliable email delivery.

• User-Friendly Interface
  JSONLint offers a simple and intuitive web interface that makes it easy to validate JSON data without the need for advanced technical skills.
• Error Highlighting
  The tool highlights exactly where the errors are in the JSON data, making it easier to identify and correct mistakes quickly.
• Free to Use
  JSONLint is freely accessible to anyone with an internet connection, making it a cost-effective solution for validating JSON data.
• JSON Formatter
  In addition to validating JSON, JSONLint also offers functionality to format and beautify JSON data, improving readability.
• Quick Processing
  The tool processes JSON data quickly, providing almost instant feedback which is useful during development and debugging.

Possible disadvantages

• Internet Connection Required
  JSONLint is a web-based tool, so it requires an active internet connection to function, which can be a limitation in offline environments.
• Basic Features
  While JSONLint is excellent for simple validation and formatting, it lacks more advanced features like schema validation or integration with development environments.
• No API
  JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
• Ads on the Website
  The website includes advertisements, which can be distracting for users and might affect the user experience.
• Limited Customization
  The tool does not offer much in terms of customization options for how errors are displayed or how JSON is formatted, which might not meet all user needs.
