Key Features
Thinking about features
During development, we decided to launch the first version with the aim of showing the basic possibilities and scope of this tool.
We are aware that in the specific areas that the tool covers, there are also narrowly focused (and often paid) tools that do a better job. In 2024/2025, however, we want to achieve that this free tool will be the most useful and universal helper for web developers and administrators in this area.
Future plans
For each feature below, you will also find the Further development ideas section, where we describe what improvements we want to implement in the following weeks and months in the given area.
We would prefer to have these features in the first version, but we didn’t want to delay the launch. We expect that your feedback will bring more light and priorities to our further development.
List of features
- Audit Report - the main output from the tool is an interactive HTML audit report that contains the outputs of all analyses and recommendations for improvement
- Audit Report Sharing (Upload) - for the easiest possible sharing of the audit report, a free service is available for online sharing of the report in the form of a secure URL with optionally limited validity and a password
- Offline Website Generator (cloner) - generates a static version of your website (clone) that you can store and browse offline without webserver. A great tool for archival purposes or robust HA (high-availability) scenarios, where regularly maintained static versions of the website can be part of DR (disaster recovery) plans
- Sitemap Generator - you can easily generate
sitemap.xml
andsitemap.txt
for your website - Mailer - crawler can send you a detailed HTML report via your SMTP server directly to your e-mail after completing the crawling (useful, e.g. in CI/CD pipelines)
- Deep Website Crawling - finds and analyzes every single page, image, font, CSS, JS or document on your website. It is really heuristic and searches even responsive images in all forms of srcset, looks for images or fonts in CSS, even parses and looks for files in the manifests of some popular frameworks
- Dev/DevOps Assistant - finds imperfections and non-optimized parts of the website that you neglected during development, helps you warm up the cache, or test the functionality of the entire website as part of your CI/CD pipelines
- Availability - maximum availability for a wide range of users and platforms is our priority, so our tool is for all platforms (Windows, macOS, Linux) and both its desktop and command-line variant
- Ease of Use - we strive to make the tool to be simple to use even for less technical users and easy to install without complex dependencies
- Exports and Reports - you can export all data to HTML report that works well on desktop and mobile, TXT (console output) or JSON for your own processing
- Improvement Meter - analyzes the current state of your website and provides a percentage of how well it is optimized in individual areas
- Stress Testing - tests the performance of your website under heavy load, because requests can be made in parallel, with any number of
workers
(but be careful not to cause a DoS attack) - SEO and OpenGraph Analysis - analyzes the SEO and OpenGraph settings of your website with an analysis of the uniqueness of your titles/descriptions
- Heading Analysis - analyzes the correct semantic structure of the headings on every single page and points out errors (multiple headings <h1> or skipped heading levels are the most common)
- Redirect and 404 Analysis - finds all URLs that are redirects or point to a non-existent page (404) so you can quickly find and fix them
- Accessibility Analysis - analyzes and recommends at least basic accessibility rules that will take developers a few tens of minutes to implement, but will help people with disabilities work well with your website
- Performance Analysis - crawler will provide detailed statistics on the duration of generation of individual pages and help to find the most vulnerable parts of your website in the event of a DoS/DDoS attack
- Best Practices Analysis - analyzes and recommends various best practices that increase user comfort and reduce error rates (clickable phone numbers, using modern WebP/AVIF images, Brotli compression, appropriate work with SVG, using quotation marks in the HTML attributes, etc.)
- Security Analysis -analyzes compliance with basic security recommendations, currently in the area of setting HTTP headers and cookies
- Content Type Analysis - provides a detailed summary of the number and volume of individual types of content on your entire website (HTML, CSS, JS, images, fonts, documents, etc.)
- Technical analysis - will provide information and recommendations to improve your DNS and TLS/SSL configuration
