The 20 Best Add-Ons and Chrome Extensions for Trello in 2021

While Trello out of the box is an extremely useful and versatile application, it lacks some of the features a project manager — especially an Agile project manager — may want. Fortunately, there are a wide variety of Trello Chrome extensions and add-ons that fill the gaps, adding powerful capabilities to the tool.

The easiest way to find Chrome extensions for Trello is to visit the Chrome Web Store and simply search for what you want. Be warned, there are at last count over 300 Trello add-ons and Chrome extensions ranging from weekend projects to fully-scaled paid apps.

When browsing for Trello add-ons and extensions, always check the Reviews tab in the Google Chrome Store to get a sense of what people are currently saying about any particular one. And don’t go adding 30 extensions all at once. Add-ons can slow down your Chrome performance, so try to keep things to four or fewer.

Scrum extensions for Trello

If you’re a project manager using Scrum, you may find Trello a bit lacking.  Thankfully, a lot of extensions have emerged to tackle certain Scrum needs, from story points to burndown charts. Here are some of our favorites.

1. Scrum for Trello

With Scrum for Trello you can easily set and display points per card and per list. It’s up to you to decide what those points represent, but it’s extremely handy to have an extension that highlights points easily.

2. ScrummerTheodo

4. Plus for Trello

If you want burndown charts but are put off by Corrello’s pricing, take a look at Plus for Trello. The extension offers reports, timers, hashtags, offline support, burndown charts, spent vs estimate by card, and many other useful features. It’s also open source if you like to customize and, unlike a lot of other Trello add-ons and extensions, has plenty of documentation. Hardly a wonder that it was named a Chrome Store Editor’s Choice. Plus for Trello is a good example of just how useful a good extension can be.
