Eleventy is stable. We’ve shipped 56 releases going back to the first version in December 2017 and only two of those releases have had Eleventy-specific breaking changes.
a11yproject.com launched with version 1.0.0 of Eleventy. […] It's been a little under three years and I haven't had to make any adjustments to its dependencies, and it can still install and run from a cold start with no complications. When I update the site to use version 2.0.0 I'll actually be removing dependencies, and not adding more. […] That's rare and special.— Eric Bailey
Eleventy uses independent template languages. We don’t want to hold your content hostage with a custom format. If you decide to use a different syntax later, having your content decoupled in this way will make migration easier.
Eleventy does not require that you use a JavaScript framework—that means zero client-side JavaScript by default across the board. We’re thinking long-term to opt-out of the framework rat race. The tool chain, modules, and components you use in your front end stack are decoupled from this tool. Work from a solid foundation of pre-rendered templates that suit your project’s progressive enhancement baseline requirements.
Eleventy works with your project’s existing directory structure. The tool doesn’t require an app directory or a pages directory. Use the structure that you want.
Eleventy allows incremental adoption. We only look for the files and directories you specify. Further, with even more precision you can opt-out or ignore specific files in your project. You don’t need to start an Eleventy project from scratch. Eleventy is flexible enough to allow conversion of only a few templates at a time. Migrate as fast or as slow as you’d like.
“I actually used Eleventy for the first time this week. Loved it.” —Paul Lewis
“Don’t tell Zach I said it but Eleventy is seeming fresh as hell so far” —Mat Marquis
“Think the reason everyone is loving [Eleventy] so much (myself included) is that it doesn't come with a prescription about data sources or template rendering.” —Brian Leroux
“I use Eleventy on almost every project at this point and I love it.” —Lea Verou
“Eleventy + Netlify have become my new workflow for static sites. I think I'm in love.” —Mina Markham
“Seriously can't remember enjoying using a Static Site Generator this much. Yes Hugo is rapid, but this is all so logical. It feels like it was designed by someone who has been through lots of pain and success using other SSGs.” —Phil Hawksworth
“I looked into and actively tried using various static site generators for this project. Eleventy was the only one I could find that gave me the fine-grained control I needed at blazingly fast build times.” —Mathias Bynens
“Eleventy is absolutely wonderful. It’s by far the nicest static site generator I’ve used in what feels like forever.” —Addy Osmani
