The original inspiration comes from being tired of having a specific site (and finding it!!) that serves my needs for a single purpose. Straight forward tools, no fuss. The objective is to be fully in-browser, no login and if possible without contacting a remote server.
PGP Key Analyser - Analyze PGP keys directly in your browser - finally I can see the infos without having to download the key on my device
Proton Date - Check ProtonMail account creation dates - pretty niche I admit
Favicon Hash - Generate website favicon hashes for OSINT - very useful if you want to find other instances that run the same favicon as your target (same owner or maybe impersonators)
Search Dorks - Generate search engine dorks for Shodan, Censys, Google and more (if you can't remember the query or if you're curious / need to translate between different engines)
GitHub Recon - Lookup GitHub users by username or email to obtain profile details, creation dates, emails, and more (makes you realize how much GitHub loves to show infos)
Metadata Viewer - Extract and view EXIF data and other metadata from images - we don't realise how much data is revealed through images metadatas...
Please let me know what you think, what are the shortcomings you see and anything you'd like to see added <3
