Zovo Chrome Extensions: 87 Free Tools, Zero Tracking

Zovo builds 84 free Chrome extensions with 60,000+ users: tab suspender, clipboard history, JSON formatter and more. No tracking, no accounts, free forever.

What is Zovo?

Zovo is a suite of 84 free Chrome extensions for productivity and privacy, built and maintained by one developer. Every extension does its work locally in your browser. There is no account requirement, no analytics pixel, and no data collection, so the tools keep working the same way whether or not anyone is watching.

The catalogue covers the jobs people actually repeat all day: reclaiming memory from idle tabs, formatting and validating JSON, keeping clipboard history, restoring tab groups and sessions, filling repetitive forms, testing regular expressions, and managing cookies. Alongside the extensions, Zovo publishes browser-based tools that run on the page without installing anything.

Popular Zovo Extensions

Tab Suspender Pro
Suspends idle tabs so Chrome stops holding gigabytes of memory it is not using. Whitelist the tabs you want left alone.
JSON Formatter Pro
Formats, validates, and inspects JSON in a readable tree. Useful when an API response arrives as one unbroken line.
Clipboard History Pro
Keeps a searchable history of what you copied, so an overwritten clipboard is no longer lost work.
Session Manager Pro
Saves and restores whole browsing sessions, including window and tab arrangement.
Form Filler Pro
Fills repetitive forms from saved profiles, for testing and for the forms you complete every week.
Cookie Manager Pro
Views, edits, and deletes cookies per site, with the detail a developer needs while debugging.

Why Privacy First

Browser extensions ask for broad permissions, and most people grant them without a way to judge the risk. Zovo takes the opposite position. Extensions request the narrowest permission set that still allows the feature to work, processing happens on your machine, and the source is open so the claim can be checked rather than trusted.

That constraint shapes the roadmap. Features that would require shipping your data somewhere do not get built.

Fixing Chrome When It Misbehaves

Not every problem is solved by installing something. Three of the questions we get most often have answers that live in Chrome itself, and we have written each one up in full.

When an extension stops loading, the error message narrows it down faster than trial and error does: Chrome extensions not working maps each message to the fix that resolves it. When bookmarks vanish, there are four distinct causes and only one of them is recoverable from a file on disk, which Chrome overwrites shortly after each launch, so read the recovery steps before reopening the browser. And if you are trying to get a dark browser rather than a dark theme on one site, the complete Chrome dark mode guide covers the desktop setting, the Android toggle and the force-dark flag, including where the flag makes pages worse.

Tools That Need No Install

Alongside the extensions, Zovo runs a set of browser-based tools that require no account and send nothing to a server. The flowchart maker draws process boxes, decision diamonds and connectors on a canvas and exports to PNG or SVG. The finance set covers a payroll calculator for withholdings and net pay, a monthly budget calculator, and a cash-out refinance calculator that compares an existing mortgage against a new one and shows the break-even point. On the kitchen side, the recipe converter handles US to metric measurements and serving-size scaling. The full list is grouped by category.
