As answered by people managing TS-V and Diffyn.

TS-V combines automated SEO, performance, HTTP, accessibility and basic security checks in a single online audit, then prioritizes the findings so users can focus on what should be fixed first. Unlike large SEO suites or desktop crawlers, TS-V is designed to be fast and simple: enter a public website URL, run the audit and receive actionable recommendations and downloadable reports without installing software or configuring complex tools.
Diffyn's answer:

TS-V's answer
TS-V is built as a web-based auditing platform using PHP, MariaDB, HTML, CSS and JavaScript.

TS-V's answer
The primary audience of TS-V includes website owners, developers, SEO specialists, digital agencies and technical teams that need a quick and understandable assessment of a website’s technical health. It is particularly useful for people who want to identify SEO, performance, HTTP, accessibility and basic security issues without setting up complex tools or installing desktop software.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
TS-V's answer
TS-V started from a practical problem: technical website audits are often split across multiple tools, each focused on only one part of the picture. Performance data may come from one service, SEO checks from another, security headers from somewhere else, and the final result is often a long list of warnings with little guidance on what actually matters. TS-V was created to simplify that process. The idea was to combine the most useful technical checks into one online audit, prioritize the findings, and turn them into clear, actionable recommendations. The goal is not to replace every large SEO platform, but to make technical website auditing faster, easier to understand and more useful for people who want to know what is wrong and what should be fixed first.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
TS-V's answer

It is primarily aimed at website owners, developers, SEO specialists and digital agencies that need fast, practical technical website audits. As the product grows, notable customer use cases may be added to the public profile.
