Top 10 Netlify Build Plugins - 2021 Update

Last May, Netlify announced the general availability of Build Plugins. Since then, a number of technical partners have launched new plugins, allowing automated workflows to run on top of Netlify’s CI/CD infrastructure.

For example, you can now run end-to-end tests with the Cypress plugin or index your site for search with Algolia, directly from your Netlify build.

With an expanding catalog of available plugins and integrations, we wanted to take this moment to check on the leaderboard.

Here’s a look at the most popular Netlify build plugins to-date, and some notes on their standing compared to last June.

Top 10 Netlify Build Plugins

1. Gatsby Cache

Holding strong at #1, this plugin by Jason Lengstorf allows you to persist the Gatsby cache between Netlify builds for huge build speed improvements.

8. Lighthouse

Another fun one in the performance space, the Lighthouse plugin by Netlify Labs generates a Lighthouse audit report for every build, so you can watch for improvements or degradations in page speed as part of your workflow.

Build a more accessible web! The A11y plugin by sw-yx runs your critical pages through Pa11y and fails the build if accessibility failures are found.

10. Inline Critical CSS

New to our Top 10 list, the Inline Critical CSS plugin by Tom Bonnike extracts the CSS for above-the-fold content and makes it inline CSS so that content can render as quickly as possible for users.

First, thank you so much, plugin authors, for bringing these plugins to life!

While we’re seeing more framework-specific plugins rise through the ranks, it’s clear that optimizing performance, search, and accessibility remain popular concerns for Netlify developers.
