    • Project mention: Launching Osint Industries: Discover Your Digital Footprint in Realtime | news.ycombinator.com | 2023-08-09

    Greetings, HN community. We are excited to share OSINT Industries, a platform dedicated to real-time open-source intelligence (OSINT) pertaining to phone numbers and emails.

    About OSINT Industries:

    Realtime Analysis: We provide an up-to-the-moment enrichment tool for emails, and phone numbers.

    Real-Time Intelligence: We refrain from using databases. Every piece of data is fetched in real-time, ensuring its accuracy and timeliness. None of the queries or results are stored.

    Extensive Reach: Our tool can identify associated accounts linked to a particular email or phone number from over 200 websites.

    Detailed Insights: Beyond basic association, our system can pull additional data points, such as images, map locations, and more.

    Pedigree: Our foundation is built upon proven tools our team made in the past like Holehe (https://github.com/megadose/holehe), GHunt (https://github.com/mxrch/GHunt), and onionsearch (https://github.com/megadose/OnionSearch).

    User Base: Within 3 months of our inception, we've got over 350k registered users.

    Trust & Reliability: Our tool has been integrated by various global law enforcement agencies, showcasing its reliability and utility.

    Try the tool for free to discover the digital footprint of your email and phone number. The first 5 searches are free: https://osint.industries

    We offer API access to enterprises, if you're interested in that contact me on [email protected].

    As our tool deals with data that some may view as sensitive, I think it is also important to link our policies here which govern our ethics, and data processing.

    Trust & Safety (our ethics): https://osint.industries/trust

  • MailCatcher

    Catches mail and serves it through a dream.

    • Project mention: Preview emails with letter_opener, MailCatcher and MailHog | news.ycombinator.com | 2023-08-13

    hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).

    MailCatcher (https://github.com/sj26/mailcatcher) and MailHog (https://github.com/mailhog/MailHog) are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.

    Happy to answer any question! thanks, harrison
