Small, browser-based tools

Djaunt Host Swap

Chrome Firefox

Rewrites hosts to other hosts before the request resolves, keeping the path, query string and fragment byte-identical. Point a fixed launch URL at a branch deploy without hand-editing a URL that carries live auth tokens.

• Holds as many swaps as you like, enabled one at a time
• Redirects before DNS resolves — the original host is never contacted
• Rules persist across browser restarts

Djaunt Query Params

Chrome Firefox

Removes and adds query string parameters on a chosen domain before the request resolves, leaving the scheme, host, path and fragment untouched. Flip flags and locales on a launch URL you cannot hand-edit.

• Removed and added params each get their own box — no comma-separated lists
• Holds as many tweaks as you like, each toggled on its own
• Applies per domain — no expiry, no tab or session scoping
• Rewrites before the request resolves, so nothing is ever double-fetched

Djaunt Header Editor

Chrome Firefox

Sets and removes HTTP request headers on a chosen domain before the request resolves. Built for testing auth and feature-flag headers, and for CORS debugging.

• Holds as many tweaks as you like, each toggled on its own
• Applies per domain — no expiry, no tab or session scoping
• Rewrites before the request resolves, so the original header never ships

Djaunt Prettifier

Chrome Firefox

Beautifies JSON, renders Markdown in a live two-panel editor, runs a structural comparison between two versions of either, and parses a URL's query string into editable params you can add to and delete from — right in the popup, with no host permissions and no network calls.

• Markdown editor with a live rendered preview — tables, task lists and all, with no raw HTML or remote images loaded — or open it full-width in a tab
• JSON diffed by property path — reformatting or reordering keys shows no noise
• Markdown diffed section by section, with word-level and item-level detail
• URL params as editable Name → Value rows — add, delete or edit them and copy the modified URL
• Download the beautified result or the diff report as a file

Djaunt Storage Inspector

Chrome Firefox

Views, edits and deletes localStorage and sessionStorage entries for the active tab's page, right from the toolbar — access granted only to the tab you click on.

• Edit a value in place, delete a stale key, or add a new one
• Filter a long list by key or value as you type
• Export the current store to a JSON file

Djaunt Tab Volume

Chrome Firefox

Sets the volume of each tab from 0 to 100 percent of the system volume, with an option to save that level for every tab on the same domain.

• Per-tab level, or "keep for this domain" to apply it site-wide
• Covers both media elements and Web Audio playback
• Attenuates only — never boosts past the system volume

Djaunt Dark Mode

Chrome Firefox

Forces a dark color scheme on any site, skipping pages that already look dark. Turn it on globally, or override it per domain for the rest of the browsing session.

• Detects an already-dark page by its background luminance
• Global switch persists; per-domain overrides last for the session
• A storage change reaches every open tab instantly

Djaunt Color Picker

Chrome Firefox

Picks any on-screen color, converts it between hex, RGB, HSL and OKLCH, checks WCAG contrast, and builds CSS gradients — a ColorZilla alternative with no host permissions at all.

• Uses the browser's native eyedropper, with a pixel-accurate fallback picker
• WCAG contrast checker and a linear/radial gradient builder built in
• Zero host permissions — the fallback only ever sees a screenshot you asked for

Djaunt Net Mock

Chrome Firefox 128+

Intercepts the page's fetch and XMLHttpRequest calls and answers the ones you choose with a response you wrote — a mock body, a forced 500, a delay, or a hard failure. No server to stand up, no app code to touch.

• Match by URL glob or regex and method; mock, fail, or pass a request through
• A window.djauntMock API, so an agent installs a rule in one line
• A match log showing what was mocked, failed, passed or skipped, and why

Djaunt Clock Tools

Chrome Firefox

Stopwatches, countdown timers and Pomodoro work/break cycles — the things a plain system clock doesn't do — all from the toolbar, with no page access at all.

• Run as many stopwatches, timers and Pomodoro cycles as you like at once
• The toolbar badge shows whichever one is soonest to finish, live
• Flashes and optionally beeps when a timer or Pomodoro phase finishes
