Best Chrome Extensions for Running a Small Business: 25 for 2026

The best Chrome extensions for a small business do one job each: summarise the terms before you sign, fix the grammar, record a screen, track a price, tame the tabs, find an email address, log the hours, fill the password and bring an AI assistant into the page. This guide lists 25, with Web Store user counts and ratings read on 3 November 2026, the price of the product behind each, and what each extension is allowed to read.

The reason to care about that last part is not theoretical. In December 2025 the security firm Koi reported that four extensions from one publisher, with more than eight million users between them and a Chrome Featured badge, had been capturing people's AI chat prompts and responses since July and sending them to the publisher's servers. A year earlier an attacker took over the developer account behind the Cyberhaven extension and pushed a malicious update that stayed live for more than a day. Chrome extensions for a small business run inside the browser that holds your bank, your email and your customers' data, and roughly half of UK web use happens in Chrome, 49% in October 2026 on StatCounter's count. Choosing them is a security decision as much as a productivity one.

Below: how we judged, the 25 in one table, the extensions by task with the price of the product behind each, the four permission words to understand before you click Add, what the NCSC tells businesses to do about extensions, and the jobs an agent takes out of the browser altogether.

How we judged

1. Web Store data read on 3 November 2026: user count, rating and last update as the listing shows them. Counts are Google's rounded figures.
2. Prices from the vendor's own page the same day, in the currency it shows. Where a page showed no figure we say so.
3. Permissions from an independent analysis. Chrome's listing page shows only the privacy categories a developer declares, so the permission notes come from the extension analyser extscope.org and are marked as such.
4. Still maintained. Anything not updated since 2024 was dropped, which removed one well-known price tracker.
5. One founder-run newcomer per section at most, labelled as new, because small extensions with a handful of ratings deserve more caution, not less.

The 25 at a glance

Reading the terms before you sign

Terms of Service; Didn't Read gives a grade to the terms of well-known services from a community of reviewers, asks for nothing beyond tabs and storage, and is free; the catch is that a small supplier's terms usually have no grade, and the extension was last updated in April 2025. Termzy AI is the newer kind: it reads the terms on whatever page you are on and summarises them, which is useful for a supplier contract nobody has reviewed, and at 260 users and six ratings it is new enough that you should read its own privacy claims before trusting it with yours. Neither is legal advice. For a lease or a supplier deal with money in it, the contract review guide is the longer answer.

Writing

Grammarly has 41 million users and reads everything you type on every site, which is both the point and the problem; its UK page shows Free and Pro at £10. LanguageTool covers 30 languages, sends the text in the active box to its own servers and needs no account, with 2,000 characters a box free; its premium price page showed an error on the day we checked, so look before you buy. Pick one. Two grammar extensions fighting over the same text box is the commonest cause of a browser that feels slow.

Screenshots and recording

GoFullPage captures a whole page with the lightest permissions of any tool on this list, active tab only, 11 million users and a 4.9 rating, and that combination is rare enough to be the default. Loom records your screen and face for the walkthrough you would otherwise type, free for 25 videos of five minutes and $18 a user a month for Business, but it asks for the screen, tabs, cookies and every site, and its store rating has slid to 2.7 on complaints about crashes. Awesome Screenshot sits between them, 4.7 from four million users, with broad site access and no price visible on its pricing page today.

Prices and purchases

PayPal Honey is the most installed and the worst rated on this list, 13 million users at 2.2, and declares web history and payment data; use it knowing that. Pouch, the UK coupon extension, now appears as hotukdeals in the Web Store, with monetised links and a smaller footprint. Keepa tracks Amazon price history and asks for access to Amazon and Keepa domains only, which is what narrow permission looks like; the old Camelizer tracker has not been updated since June 2024 and we dropped it.

Tabs

OneTab collapses every open tab into a list, stores it locally and asks for nothing from the sites themselves; lose the browser profile and you lose the list. Workona turns tabs into named workspaces, reads tabs and history but not page content, and keeps the data on its servers behind an account. Tab Manager Plus is free and open source with a 4.5 rating. Tabwright is a founder-run newcomer that saves sessions and crash snapshots with no account, free for three sessions and $6.99 once for Pro; we read its vendor page but could not load its store listing on the day, so check the install link yourself.

Finding leads

Hunter finds a company's email pattern and addresses from the page you are on, 4.8 from 700,000 users, with tabs and storage only, 50 free credits a month and Starter at £28 a month on yearly billing in its UK pricing. Apollo gives unlimited email credits free and asks for the broadest access of the three, with no prices visible on its pricing page today. Lusha charges credits for verified emails and five for phone numbers, from $37.45 a month on the yearly Starter plan. Whatever you find, UK cold email is only lawful to companies, not to individuals, under PECR; the cold-outreach rules in the link-building guide apply here too.

Time

Clockify is the one listing on this page that says in its own words that it asks to "read and change all your data on the websites you visit", to add a timer button inside other apps, and that you can switch that off under Integrations. That candour is worth more than its 2.8 rating suggests. Its Free plan has no time limit and Basic is $3.99 a seat a month on yearly billing. Toggl Track keeps its access to its own domains, the tightest scoping on this list, and its pricing page was not loading when we checked.

Passwords

Bitwarden and 1Password both ask for broad access because autofill needs it, and both are the right kind of broad: open source in Bitwarden's case, audited in both. Bitwarden is free with Premium at $19.80 a year; 1Password has no free tier and costs $3.99 a month on yearly billing. The password and privacy guide compares them in depth. The permission to watch for in any other extension is the one these two need legitimately: reading and changing data on every site.

Reading out loud

Read Aloud turns any page into speech with local voices free and cloud voices paid, six million users, active tab only. The reader-mode extensions we looked at were either delisted or look-alikes with a handful of users; Chrome's own reading mode in the side panel does the job without an install.

AI in the browser

This is the category to install slowly. Claude in Chrome sits in the side panel, reads the page and can click and fill forms on your behalf; it needs a paid Claude plan, Pro at $17 a month on yearly billing, and its permission set includes the debugger, which is the most powerful thing an extension can hold. OpenAI's ChatGPT extension declares the broadest data categories on the list, including health and financial information, and lists history, bookmarks and downloads among its permissions; OpenAI says it asks before sensitive actions. Monica bundles several models into one sidebar, 4.8 from three million users, with a Singapore publisher and payment data declared. We could not find an official Microsoft Copilot extension for Chrome, only clones, and Google's Gemini is built into Chrome rather than installed from the store.

The rule for all three: an agent extension that can act in the browser has the same reach as you do while logged in. Give it a profile without the bank.

The four permission words

1. "Read and change all your data on all websites." Needed by password managers, grammar checkers and AI agents; a red flag on a coupon tool or a tab saver.
2. Host permissions. Which sites. Keepa asks for Amazon; Toggl asks for Toggl. Fewer is better.
3. Web history. Declared by Honey, Toby, Compose AI and the two big AI extensions. Ask why a tool needs where you have been.
4. Debugger and native messaging. The deepest hooks, held by the AI agents and the password managers. Fine in a tool you would trust with your login; alarming anywhere else.

Chrome's own rules say an extension must request "only the narrowest set of permissions necessary" and may use your data only for its stated purpose, and since Manifest V3 all of an extension's code must ship in the package rather than load from a server. The Manifest V2 switch-off finished in stages, disabled on every channel on 24 July 2025 and removed from the store on 31 August 2026, which is why some older favourites vanished. None of that stops a publisher from writing a privacy policy that permits selling your data, which is what the Urban VPN case turned on.

What the NCSC says a business should do

The National Cyber Security Centre's browser guidance, reviewed in May 2025, is short: extensions can typically read or alter data on any site, so set a policy for which third-party extensions staff may install, keep automatic updates on for the browser and its extensions, and treat them like any other third-party software. For a three-person firm that means a written list, a separate browser profile for banking with no extensions at all, and a quarterly look at chrome://extensions to remove what nobody uses.

What an agent takes out of the browser

Most of the extensions above exist because a task has to happen inside a web page. An agent does the task somewhere else.

• Reads the contract properly. Paste or upload the supplier terms and it returns the clauses that matter, with Jobbit's research attaching the sources, instead of a grade from a community that never saw your contract.
• Builds the lead list without an extension on every page. It finds the companies, the roles and the published contact routes, and keeps the PECR rule.
• Logs the hours from the calendar and the inbox, not from a timer button injected into every site.
• Writes the walkthrough you would have recorded, as a step-by-step page your customer can search.
• Checks the price history of a supplier's product before you reorder.

ChatGPT, Claude, Gemini, Microsoft Copilot, Manus and Meta's Muse will all summarise a page if you ask. What they do not do is run the job on a schedule or bring in a human from the network when the contract needs a solicitor. That is what Jobbit is for.

Your first hour

• Open chrome://extensions and remove anything you have not used this month.
• Make a second profile for banking and HMRC with no extensions.
• Install at most one per task: one grammar tool, one screenshot tool, one tab tool, one password manager.
• Read the Privacy tab on the store page before adding anything that declares web history.
• Write the list down and tell anyone who works with you that it is the list.

Frequently asked questions

What are the best Chrome extensions for a small business?

One per task: GoFullPage for screenshots, Grammarly or LanguageTool for writing, OneTab or Workona for tabs, Hunter for finding business emails, Clockify or Toggl Track for hours, Bitwarden or 1Password for passwords, Keepa for Amazon prices, and Claude in Chrome or ChatGPT if you want an AI that acts in the page. Figures in this guide were read from the Chrome Web Store on 3 November 2026.

Are Chrome extensions safe for business use?

Only as safe as their publisher. Chrome's rules require the narrowest permissions and ban selling your data, but in December 2025 four extensions with over eight million users were found capturing AI chat conversations, and in December 2024 a hijacked developer account pushed a malicious update to a legitimate extension. The NCSC advises businesses to set a policy on which extensions staff may install and to keep updates automatic.

How do I see what a Chrome extension can access?

Open chrome://extensions, click Details on the extension and read "Site access" and the permissions list, or read the Privacy tab on its Web Store page, which shows the data categories the developer declares. Independent analysers such as extscope.org list the manifest permissions. "Read and change all your data on all websites" is the line to question.

Is there a Microsoft Copilot extension for Chrome?

We could not find an official one on 3 November 2026; the listings under that name are third-party clones that say so. Copilot runs in Edge and on the web. Google's Gemini is built into Chrome rather than installed from the store, and Perplexity's store listing is a bridge for its desktop app rather than a sidebar.

Do extensions slow Chrome down?

Each one runs code on every page it has access to, so broad-access extensions cost memory and time on every load. Two grammar checkers on the same page, or several AI sidebars, are the usual culprits. Keep one per task and remove what you have not used in a month.

Can an AI agent replace Chrome extensions?

For the tasks that do not have to happen inside a page, yes: reading a contract, building a lead list, logging hours from the calendar, writing a walkthrough, checking a price before a reorder. A Jobbit agent does those with 100 free credits a day and no card, and brings in a person from the network when the task needs one.
