DataHarvester 1.0.0 — A Windows tool for collecting and verifying public files

Hi everyone!

I've just released DataHarvester 1.0.0, a small Windows desktop utility designed for repeatable collections of public HTTPS files.

I built it around a simple problem: when collecting files from multiple public sources, I wanted a way to keep track of what was downloaded, verify that local copies remained intact, and avoid downloading unchanged files unnecessarily.

What it does:

• Save reusable collection plans as JSON profiles.
• Download files from explicit public HTTPS URLs.
• Verify file integrity using SHA-256 references.
• Reuse previously verified local files when eligible.
• Browse collection history and export reports to CSV.
• Export verified copies without overwriting existing files.

The application is portable, works locally, and has a redesigned interface available in English and French.

Platform: Windows 10/11 x64
Price: CAD $4.99

It isn't a universal web scraper or a replacement for advanced download managers. The focus is on repeatable file collections, integrity checks, and keeping a clear record of results.

I'm interested in feedback, especially from anyone who regularly works with public datasets or downloadable research files.

Development transparency

DataHarvester was developed with generative AI assistance, including AI-generated code and documentation.

Product requirements, feature decisions, manual acceptance testing, and release approval were handled by the developer. The software has also undergone automated testing and dedicated reliability reviews.

DataHarvester runs locally and does not require an AI service or account to operate.
