CachePlex - All-in-one free digital marketing and SEO toolkit for website owners

Core Toolkit Features

CachePlex hosts 22 web tools that run directly in the browser, with no installation or mandatory setup. 17 of these tools are available for free, with no credit card required to start using them immediately. All core free tools do not demand user account creation, and users only need to register if they want to save their scan history.

SEO Analyzer

The primary featured tool scans any public website URL to evaluate 50+ on-page SEO factors in under 10 seconds. It generates a scored report out of 100, covering meta tags, heading structure, image alt attributes, structured data, internal links, page speed, and mobile friendliness. Powered by Google Gemini AI, it adds a prioritized summary of specific actionable fixes instead of generic guidance.

AI Humanizer

This tool rewrites formal or robotic AI-generated text into natural, human-readable content, with a measurable reduction in readability grade from higher levels (e.g. Grade 16) to simpler, more accessible levels (e.g. Grade 8). It supports free daily usage quotas, one-time word packs starting at $0.99, and an optional $4.99 monthly plan.

SEO Meta Generator

Users can input a target keyword to generate multiple character-perfect SEO title and meta description variations, ready for bulk export via CSV. It offers 3 free page generations per day, with one-time page packs starting at $4.99 and an optional $14.99 monthly plan. Outputs are formatted to fit Google's current search result length limits.

Visual Asset Generators

• App Icons Generator: Takes a single source logo image and outputs 15 pre-sized PNG files compatible with iOS, Android, Xcode, and Android Studio, packaged as a single ZIP file.

• Favicon Generator: Processes uploaded logos to generate all required favicon sizes, including 16x16 and 32x16 ICO files, plus PNG variants for desktop browsers, iOS, and Android devices.

• PostPlex: A browser-based social creative studio with 40 professionally designed templates (24 free, 16 Pro). Users can edit text directly on the canvas, adjust fonts and accent colors, and export platform-sized social post images for feeds, squares, stories, and link previews without any design software. All processing runs locally in the user's browser, so uploaded artwork never leaves their device.

Upcoming Tools

Additional tools listed as in development include Backlink Checker, Keyword Position Tracker, Image Compressor, PDF processing utilities, Keyword Density Checker, Page Speed Analyzer, and AI Content Optimizer. Some of these upcoming tools will be released as free options, others will be available as premium features.

Privacy and Usage Policy

CachePlex only scans publicly visible page content. It does not request or store user credentials, and it never accesses private CMS environments. There is no mandatory subscription required to use any tool, and premium features operate on a pay-as-you-go model with one-time purchase packs available alongside optional monthly plans. Core free tools remain free permanently.
