We were draftjs, but it got very slow on larger texts. We're replacing with slate but it lacks some very needed textnode manipulation.
Glancing at the editor and api, wow. Can't wait to have something simple (content editable) but with strong api backbone. Congrats!!!
Did you try CKEditor 5? It's a modern rich-text editing framework with a rich API. However, it also comes with a lot of polished and ready-to-use features. You can read more on: https://ckeditor.com/ckeditor-5/.
Since you mentioned CKEditor 5, I'll be bold enough to go a bit into off-topic.
CKEditor 5 is an incredibly impressive endeavour, and I've been following it with great interest. However, one of the things that separates it from the competition is the GPL license, which makes it impossible to use the editor in a permissively-licensed (Apache2/MIT) open source project. Your founder has indicated a readiness[1] to grant a custom license to such projects.
So, I'm wondering whether that is still the policy, and how that's been working out in practice. Have any projects taken you up on the offer? Have there been any unforeseen problems? What are the legal limitations imposed (on distributors/forks of the project, for example)?
Yes, the "Free for Open Source" initiative is up and running. For now, we didn't promote it a lot because we wanted to learn how it works, but from what I know, the custom license that we proposed is already used by a couple of projects.
Based on the feedback that we got so far, we're right now working on a simplified version of this license. Its initial version still had some restrictions which didn't work for Apache2/MIT projects with a commercial branch. Plus, it was simply too long for normal people :). We're removing these limitations. Once it will be polished, we will talk about it more officially on ckeditor.com.
