Desktop SEO Audit Tool Development

I need a complete desktop-based SEO audit tool that can be installed on Windows (and, if feasible, macOS). The application must combine three core capabilities:

• Keyword analysis – pull search-volume data, difficulty scores, and suggest related keywords.
• Backlink checking – fetch live backlink data, identify toxic links, and summarise domain authority metrics.
• Site-speed analysis – run local tests on page load time, flag bottlenecks, and offer optimisation tips.

A simple, intuitive GUI is essential; command-line only solutions won’t work for my target users. The final build should generate branded PDF or CSV reports that can be exported with one click.

I’d like the project wrapped up within a month, including a short period for my testing and your bug fixes. Please use mainstream, well-documented libraries so future maintenance is straightforward and provide:

1. The compiled installer(s)
2. Source code with brief inline comments
3. A concise user guide (PDF or Markdown)

Let me know which tech stack you propose and any clarifying questions you have so we can start right away.
should be mobile-friendly!
