About Probe Toolkit

What Is Probe Toolkit?

Probe Toolkit is a free, open-access collection of IT, network, and developer tools designed for professionals and curious minds alike. Whether you need to run a quick DNS lookup, check an SSL certificate, generate a secure password, or decode a Base64 string, Probe Toolkit has you covered — all from a single tab in your browser.

There is no signup required, no account to create, and no personal data collected. Just pick a tool and start probing.

Who Built It?

Probe Toolkit is built and maintained by Patchen Technologies LLC, a technology company focused on building practical, privacy-respecting software tools. We believe that essential network utilities should be accessible to everyone, not locked behind paywalls or buried in ads.

Our Philosophy

Three principles guide every decision we make:

  • Privacy first. Client-side processing is used wherever possible. When your data can be processed entirely in your browser, it never touches our servers. For tools that require server-side lookups, data is processed in memory and never stored or logged.
  • Speed matters. Every tool is built for instant feedback. No frameworks, no bloated dependencies, no unnecessary loading screens. You click Probe, you get results.
  • Transparency always. We do not use third-party tracking pixels or analytics services. We do not sell data. We do not build user profiles. The tools work for you, not the other way around.

Tech Stack

Probe Toolkit is intentionally built with a lean, no-framework approach:

  • Frontend: Vanilla JavaScript (ES6+), HTML5, and CSS3 with custom properties for theming.
  • Backend: PHP 8.1+ running on Apache, handling server-side lookups and API endpoints.
  • Infrastructure: Hosted on Hostinger with HTTPS enforced on every request. Domain registration, DNS, and hosting all managed through Hostinger.

No React, no Angular, no build step. Pages load fast, tools respond instantly, and the codebase stays maintainable.

Our Tools

Probe Toolkit offers a growing collection of tools organized across six categories:

  • DNS — DNS record lookups, WHOIS domain information, and MX record checks.
  • Network — IP geolocation, public IP detection, and subnet calculations.
  • Email — Mail server verification and MX record validation.
  • Web — SSL certificate inspection and HTTP status code references.
  • Security — Password generation, Base64 encoding/decoding, URL encoding, and cryptographic hashing.
  • Developer — JSON formatting, epoch time conversion, regex testing, and more.

New tools are added regularly. If there is something you would like to see, reach out through our support page.
