Chrome Extension

Code Tools, right in your browser

A growing toolkit of small browser utilities — JSON formatting, cache clearing, password generation and cookie editing — bundled behind a single toolbar icon.

The extension is finishing review. Bookmark this page or check back shortly.

A peek at the toolbar popup.

Why use the extension

Lives in your toolbar

One click from any page — no tab switching, no URL bar typing.

Scoped to the current tab

Tools act on the active origin, so Clear Cache and Cookies only touch what you mean.

Works offline

No remote backend. Every tool runs locally inside your browser.

Private by design

No analytics, no telemetry, no account — settings stay on your device.

What is inside

Each tool is opt-in, runs locally in your browser, and ships with the extension.

JSON Formatter

Auto-detects raw-JSON pages and replaces them with a pretty-printed, collapsible tree. Per-origin opt-out and a 1 MB size guard with manual fallback.

Clear Cache

Clears cache, cookies, localStorage, IndexedDB or sessionStorage scoped to the active tab's origin. Each data type is individually selectable.

Password Generator

Crypto-secure passwords using crypto.getRandomValues with length, character-class toggles, ambiguous-character exclusion and persisted settings.

Cookie Editor

Lists every cookie for the active tab — add, edit, or delete cookies including identity fields like name, domain and path.

How to install

  1. Open the Chrome Web Store listing using the button above.
  2. Click "Add to Chrome" and confirm the requested permissions.
  3. Pin the Code Tools icon to your toolbar for one-click access.

Frequently asked questions

Which browsers are supported?

The extension ships for Chrome and Chromium-based browsers (Edge, Brave, Arc, etc.) via the Chrome Web Store. Firefox and Safari builds are not available yet.

Does the extension send my data anywhere?

No. The extension has no remote backend and no telemetry. Everything runs locally in your browser. See the privacy details for a permission-by-permission breakdown.

How do I uninstall it?

Right-click the toolbar icon and pick "Remove from Chrome", or open chrome://extensions and remove Code Tools from there. Stored settings are deleted with the extension.

Why does the extension ask for "<all_urls>"?

Some tools (JSON Formatter, Clear Cache, Cookie Editor) need to act on whichever page is open in your active tab. That permission lets them work everywhere, but the extension still only reads/writes the active tab on demand — it does not run in the background.

Permissions & privacy

The extension only uses the permissions it needs to make each tool work. Nothing leaves your browser.

  • storage — remembers your settings between sessions on your device.
  • browsingData — lets Clear Cache wipe data scoped to the active tab's origin.
  • tabs — reads the active tab's URL so each tool runs on the right origin.
  • scripting — injects the JSON Formatter view into raw-JSON pages.
  • clipboardWrite — supports one-click copy for generated passwords and formatted JSON.
  • cookies — required by the Cookie Editor to read and modify cookies for the active tab.

No analytics, no remote calls, no account required.
