37 Google Workspace Add-Ons Worth Installing

Google Workspace (formerly G Suite) is one of the most robust and reliable collections of productivity apps for the workplace. With Gmail, Docs, Sheets, Slides, and dozens of tips and tricks, it covers nearly every business need.

But many Google Workspace users don’t explore the add-ons that make these apps even more powerful. This guide covers 37 add-ons across Gmail, Google Docs, and Google Sheets that are genuinely worth installing.

Key Insight

Google rebranded G Suite to Google Workspace in October 2020. The apps and add-on ecosystem remain the same. Add-ons are customizable extensions that enhance Google Workspace apps with new features, automation, and third-party integrations.

Chrome Extensions, Editor Add-Ons and Google Workspace Add-Ons Are Three Different Things

Most roundups in this category treat “add-on”, “extension” and “plugin” as one word with three spellings. Google doesn’t. The three install from different stores, run in different places, and give an administrator different controls.

Question	Chrome extension	Editor add-on	Google Workspace add-on
Where you install it	Chrome Web Store, per browser profile	Google Workspace Marketplace, per Google account	Google Workspace Marketplace, per Google account or domain
What declares it	A manifest.json file that Chrome reads	An Apps Script manifest, per Google’s developer documentation	An addOns block in the project manifest, per Google’s developer documentation
Where the code runs	Inside the Chrome browser, as a service worker plus content scripts	Inside Google’s Apps Script sandbox	On Apps Script or your own server, rendered as a card inside the host app
How permissions work	Chrome enforces a permissions and host_permissions list from the manifest	Google enforces an oauthScopes list through the OAuth consent screen	Google enforces an oauthScopes list through the OAuth consent screen
Works in the Gmail mobile apps	No. Chrome extensions are desktop only	No. Google states editor add-ons work in desktop clients only	Yes. Google says one add-on serves the desktop and mobile versions
Which host apps it reaches	Any web page the manifest grants access to	Google Docs, Sheets, Slides and Forms only	Gmail, Calendar, Chat, Docs, Drive, Meet, Sheets and Slides
How an admin controls it	Chrome enterprise policy	Google Workspace Marketplace app access settings in the Admin console	Google Workspace Marketplace app access settings in the Admin console

Google’s add-on types reference is blunt about the mobile gap. It says editor add-ons “only function in desktop clients, not Android or iOS”, and that they “must be implemented in Apps Script”.

Google has announced no deprecation date for editor add-ons. Anyone telling you they’re being switched off is guessing.

Google Workspace Add-Ons for Google Drive and Google Slides

Drive and Slides are documented host applications, which surprises people who assume add-ons stop at Gmail, Docs and Sheets. One Google Workspace add-on can surface in all four surfaces at once, because the addOns block declares each host app separately.

In practice most Drive-facing tools are the same file and document utilities listed under Docs and Sheets below, surfaced from a different panel. If you’re hunting specifically for Drive or Slides tools, filter the Google Workspace Marketplace by app rather than by category.

How to Install and Remove a Google Workspace Add-On

Google documents the install path in its Workspace add-ons help article. The steps are the same in Docs, Sheets, Slides and Gmail.

1. Open Gmail, Docs, Sheets or Slides on a computer.
2. Click Extensions, then Add-ons, then Get add-ons. In Gmail, click the plus icon in the right side panel instead.
3. Pick the add-on and click Install.
4. Read the permission list on Google’s consent screen, then click Allow if you’re happy with it.
5. To remove it, open Extensions, then Add-ons, then Manage add-ons, click the three-dot menu on the add-on and choose Uninstall.

What Google Requires Before an Add-On Can Read Your Mail

An add-on that reads your inbox needs a restricted OAuth scope, and Google puts a real compliance burden behind that. None of the pages ranking for this topic mention it. That’s odd, because it’s the best filter for deciding whether a small add-on is safe to install.

Google’s Marketplace app review page sets the bar for publishing publicly. Its review criteria require that an app “has passed OAuth verification” and “uses the narrowest OAuth scopes possible”.

Scopes come in two escalating tiers. Google’s OAuth verification guidance states that apps requesting sensitive or restricted scopes “must complete Google’s OAuth app verification before being granted access”.

Restricted scopes carry a recurring cost that most buyers never see. Google’s restricted scope verification page puts it plainly.

“To keep access to any verified restricted scopes, apps must be reverified for compliance and complete a security assessment at least every 12 months after your assessor’s Letter of Assessment (LOA) approval date.” Google standardizes that assessment on the App Defense Alliance and its CASA framework.

That’s an annual third-party audit, paid for by the vendor, for any add-on that holds deep mailbox access on its own servers. It’s a fair question to ask a vendor before you install. It’s also a fair reason to distrust a free tool that wants full Gmail access.

Google Documents Four Admin Access Tiers, Not Three

Workspace administrators control third-party apps from Security, then Access and data control, then API controls. Google’s app access control page documents four settings, and the middle one is the one nobody quotes.

• Trusted. Google says the app “has access to all Google Workspace services”.
• Specific Google data. The tier between Trusted and Limited, which most write-ups leave out entirely.
• Limited. Google says the app “can only access unrestricted services”.
• Blocked. Google says the app “can’t access any Google data”.

Admins can also allowlist Marketplace apps or install them across a domain, which Google covers in a separate allowlisting article. Chrome extensions sit outside that mechanism, because Chrome governs them through browser enterprise policy instead.

What We Corrected on This Page

Refreshing a list like this means auditing your own claims first. Here’s what changed and why.

Correction one. Grammarly, Just Not Sorry and Giphy were listed under Gmail add-ons. All three are Chrome extensions rather than Google Workspace Marketplace apps, and the entries now say so.

Correction two. KeyRocket is gone. KeyRocket’s own website now says Keyficient is “the spiritual successor of KeyRocket”, so the entry is marked retired.

Correction three. The page used G Suite branding in its title and headings. Google renamed the platform Google Workspace in October 2020 and the store is the Google Workspace Marketplace, so the page follows Google.

Correction four. The distinction in the table above wasn’t on this page before. An admin can allowlist or block a Marketplace add-on from the Admin console, while a Chrome extension needs a browser policy.

We’re EmailAnalytics, and we sell email analytics for Gmail and Outlook rather than a general add-on suite. Almost nothing on this list competes with us. Our own product does need mailbox access, which is why what we charge per inbox and what we do with that access are both published.

Frequently Asked Questions

What are Google Workspace add-ons?

Google Workspace add-ons are customizable extensions for apps like Gmail, Google Docs, and Google Sheets. They add new features, automate tasks, or integrate third-party services directly into your Workspace apps.

You can find and install them from the Google Workspace Marketplace.

Are Google Workspace add-ons free?

Many are free, including Gmail’s built-in add-ons, Grammarly (basic), Just Not Sorry, Giphy, and the Google Analytics Sheets add-on. Others like Boomerang, Gmelius, and Supermetrics offer free tiers with paid plans for advanced features.

How do I install a Google Workspace add-on?

For Gmail, click the plus icon in the right sidebar to browse add-ons. For Google Docs and Sheets, click Extensions in the top menu, then Add-ons, then Get add-ons.

You can also browse the Google Workspace Marketplace directly at workspace.google.com/marketplace.

What is the best Gmail add-on for productivity?

EmailAnalytics is best for tracking email productivity metrics like response time and volume. Boomerang is best for scheduling and follow-up reminders. Sortd is best for visual inbox organization.

What is the best Google Docs add-on?

Grammarly is the most useful Google Docs add-on for writing quality. Lucidchart Diagrams is best for charts and visuals. Dropbox Sign (formerly HelloSign) is best for electronic signatures.

What is the best Google Sheets add-on?

Supermetrics is the best for pulling marketing data from 50+ sources. The Google Analytics add-on is essential for website reporting. Power Tools provides the broadest set of spreadsheet utilities.

Is G Suite the same as Google Workspace?

Yes. Google rebranded G Suite to Google Workspace in October 2020. The apps are the same: Gmail, Docs, Sheets, Slides, Drive, Calendar, and Meet. All add-ons that worked with G Suite continue to work with Google Workspace.

What is the difference between a Google Workspace add-on and a Chrome extension?

A Chrome extension installs from the Chrome Web Store, runs inside the browser, and is declared by a manifest.json file. A Google Workspace add-on installs from the Google Workspace Marketplace, runs on Apps Script or a vendor server, and is declared by an addOns block. Only the Workspace add-on works in the Gmail mobile apps.

Which apps can a Google Workspace add-on run inside?

Google documents eight host applications for Google Workspace add-ons: Gmail, Calendar, Chat, Docs, Drive, Meet, Sheets and Slides. Editor add-ons are a separate, older type that reaches Docs, Sheets, Slides and Forms only, and Google requires them to be written in Apps Script.

Are Google Workspace add-ons safe to install?

Google requires OAuth app verification for any add-on requesting sensitive or restricted scopes, plus Marketplace app review before public listing. Add-ons holding restricted scopes on their own servers must also complete a third-party security assessment at least every 12 months. Check what scopes an add-on asks for on the consent screen before you click Allow.

Can a Workspace admin block a specific add-on?

Yes. Google documents four app access settings in the Admin console: Trusted, Specific Google data, Limited and Blocked. Admins can also allowlist Marketplace apps or push an install across a domain.
