I've been building a Windows desktop tool that parses raw HTML locally and extracts embedded media endpoints.

It runs fully offline (no telemetry, no accounts) and can export structured results as CSV, JSON, or PDF with integrity hashes (SHA-256).

It was originally built for repeatable QA validation and archival workflows where deterministic results matter more than headless automation.

Architecture notes (for those interested): - Electron (sandboxed, context-isolated) - No use of eval() - Deterministic scoring of candidate endpoints - Optional CLI mode for batch processing

I'm mainly looking for feedback on: - Whether this is useful outside of QA / archival contexts - Expectations around cross-platform support - One-time license vs SaaS for a desktop utility
