Popular dev detectors send every domain you visit to external servers under the guise of "updating signature caches". This data is often packaged and sold to corporate databases to track internet tech trends.
Bananarr packages its matcher locally. It has no account system or app backend API, while active-tab header and DNS checks are used only for HTTP and hosting/IP evidence.
The signature database and matching logic are packaged locally inside the extension. No app server or user account is required.
Signatures match locally against in-memory data, so scans complete within seconds on a typical page.

Don't let the lightweight size fool you. Bananarr is custom-tailored to pack everything a modern developer needs.
Scans DOM selectors, scripts, links, images, cookies, and meta tags in the isolated extension world, then reads page-defined window globals from the main world.
Instantly groups detected tech across color-coded categories, from languages, backend, frontend, CSS, CMS, and e-commerce to hosting, analytics, security, payments, and engagement widgets.
Bundled signatures cover frameworks, payments, CDNs, hosting, and libraries. Active-tab header and DNS checks feed a local IP range database for AWS, Cloudflare, Fastly, Akamai, Google Cloud, Azure, and more.
Every technology match is paired with the evidence that triggered it, including meta tags, script, link, and image URLs, globals, cookies, headers, DOM elements, IP ranges, or implied relationships.
No sign-ups, accounts, trials, upgrade prompts, or query quotas. Install the extension and inspect the active tab immediately.
Built on modern Chrome extension rules with tab-scoped scripting permissions, plus a narrow DNS host permission for IP resolution. Scans only the current active tab when you run it.
A simple, highly secure pipeline that finishes in a fraction of a frame.
Click the Bananarr icon or press Mac: ⌥ + B / Windows: Alt + B . Bananarr requests tab scripting permissions dynamically.
The extension injects a DOM scanner and a globals scanner to compile metadata, selectors, scripts, and variables from the tab.
The scanner sends data back to the popup, which matches against the signature list and lists results organized by category.
Install Bananarr from the Chrome Web Store and instantly start profiling technology stacks.
You pressed Mac: ⌥ + B / Windows: Alt + B . Once installed, this opens the extension instantly.
