CLOCKEDF12

DevTools evidence, organized for investigators.

CLOCKEDF12 is a browser extension that automatically examines the technical information available through Chrome DevTools. It identifies and organizes network activity, API responses, JavaScript, page data, browser records, and other technical evidence. Findings are explained in plain language, traced to their original sources, and examined for potential investigative connections.

Runs inside your own browser · nothing is uploaded anywhere

CLOCKEDF12 Overview

CLOCKEDF12 runs supported Chrome DevTools inspections for you. It examines network requests, APIs, JavaScript, hidden page information, and browser records, then organizes and explains what it finds. It also helps identify potential investigative leads and follow supported public-source research.

It identifies findings, explains each one in plain language, traces it to its original source, and runs supported follow-up research on genuine leads. Everything is ranked so the findings that deserve attention come first.

The actual scans take place in the installed extension, inside your own browser. Not on this website. Nothing is uploaded anywhere; the extension keeps working with your network cable pulled. This page covers what it is, how to install it, and how to use it.

Download & Install

Available for Chrome

CLOCKEDF12 is live on the Chrome Web Store. Use Install for Chrome below to open the official listing and add it to your browser. The Microsoft Edge Add-ons listing is still pending approval.

CLOCKEDF12 performs its investigations inside your browser. You install it from a browser extension store or load it manually; it is not run from this website.

On a phone, tapping Install for Chrome opens the official listing so you can read it; actual installation needs Chrome on a desktop computer, because iPhone browsers cannot install desktop Chrome extensions.

Install from the Chrome Web Store
  1. Open Chrome on a compatible desktop computer.
  2. Visit this CLOCKEDF12 page.
  3. Select Install for Chrome.
  4. The official Chrome Web Store listing opens.
  5. Select Add to Chrome.
  6. Confirm the installation.
  7. Open Chrome's Extensions menu.
  8. Locate CLOCKEDF12.
  9. Pin the extension if you want it one click away.

Status: available on the Chrome Web Store · Microsoft Edge Add-ons listing still pending · Privacy Policy

CLOCKEDF12 is listed in the Chrome Web Store and installs from the official listing or the release ZIP below. The Microsoft Edge Add-ons submission is still in review, so the Edge icon stays in place without a link until that listing is verified. Any other store listing claiming to be CLOCKEDF12 is not from The OSINT Vault.

Manual install steps for the release ZIP
  1. Download the ZIP above and extract it to a folder you keep.
  2. Open chrome://extensions (Chrome) or edge://extensions (Edge).
  3. Enable Developer mode.
  4. Click Load unpacked.
  5. Choose the extracted folder, the one containing manifest.json.
  6. Open CLOCKEDF12 from the Extensions menu in the toolbar. Pinning it keeps it one click away.

DECODE F12

DECODE F12 is the educational reference behind the extension: what DevTools actually sees, where information lives inside a browser, how to read status codes, identifiers, and timestamps, and how investigators tell a real lead from a routine record. It is searchable, every topic expands on demand, and it assumes no programming background. The same reference explains what CLOCKEDF12's pivot labels mean, including what a match does not prove.

DECODE F12 Open the full reference. Four sections, searchable: Understanding F12, Where Information Lives, Reading the Data, Investigative Techniques.

Using CLOCKEDF12

  1. Install the extension and open the page you want to investigate in a normal tab.
  2. Open CLOCKEDF12 from the Extensions menu. It works in the side panel, next to the page.
  3. Optionally enter a search target, such as a username, email, domain, or IP. Targets sharpen relevance; the scan works without one.
  4. Press Start scan, then use the page normally. CLOCKEDF12 records while you browse and finishes on its own when activity settles.
  5. Read the prioritized findings. High Interest comes first; every finding carries a one-line insight and an expandable explanation.
  6. Click any finding to open the original source evidence: the captured request, response body, storage record, or script it came from.
  7. Where a finding was followed up, inspect what was investigated, which sources were queried, what came back, and what the relationship assessment established or failed to establish.
  8. Export the findings from the export tab when you need them outside the browser.

What the extension does and does not do. CLOCKEDF12 automates the inspection side of DevTools: recording traffic, reading page data and storage, tracing findings to sources, and running supported public-source follow-up on leads. It does not replace the rest of DevTools: editing pages, debugging JavaScript, profiling performance, and similar manual work stay manual. It cannot access data the site never delivered to your browser, and it does not bypass browser security. Everything it shows you was already on your machine.
