Buttondown vs Sulu: at a glance
What is Buttondown?
Buttondown lets writers reorder editor blocks without a mouse.
Buttondown is a newsletter platform shipping small daily batches. The 13 November batch lets writers reorder editor blocks and the newsletter switcher with Option + Shift + arrow keys or by clicking a drag handle. It extends a week of accessibility work: arrow-key toolbar navigation on 11 November and screen-reader names for form controls on 12 November.
What is Sulu?
Sulu opens its 3.1 line while 3.0 and 2.6 keep shipping in lockstep.
Sulu is a Symfony-based CMS released as matched 3.0.x and 2.6.x patches. The October 1 pair added a request log admin view and a guided forced two-factor setup, and the October 29 pair let editors copy content to several locales at once. The same day, 3.1.0-alpha1 opened the next line with route field actions, a media download button and product-family attributes.
Buttondown vs Sulu: editorial side-by-side
Buttondown
5.0MKT AUTO
Buttondown lets writers reorder editor blocks without a mouse.
◆ Current state
Buttondown is a newsletter platform shipping small daily batches. The 13 November batch lets writers reorder editor blocks and the newsletter switcher with Option + Shift + arrow keys or by clicking a drag handle. It extends a week of accessibility work: arrow-key toolbar navigation on 11 November and screen-reader names for form controls on 12 November.
◆ Where it's heading
Most of November's batches are fixes, but the last three days show a focused push to make the editor usable without a mouse or with a screen reader. Analytics readability (the 9 November comparison chart) and technical-content rendering (6 November) are the other recurring threads.
◆ Prediction
Expect more keyboard and screen-reader fixes across the remaining editor and settings screens over the next few batches.
Sulu
5.0MKT AUTO
Sulu opens its 3.1 line while 3.0 and 2.6 keep shipping in lockstep.
◆ Current state
Sulu is a Symfony-based CMS released as matched 3.0.x and 2.6.x patches. The October 1 pair added a request log admin view and a guided forced two-factor setup, and the October 29 pair let editors copy content to several locales at once. The same day, 3.1.0-alpha1 opened the next line with route field actions, a media download button and product-family attributes.
◆ Where it's heading
Sulu is starting a feature line while keeping two maintenance lines in sync, with security and admin hardening flowing into both. Product attributes in 3.1 point toward commerce-adjacent content modelling.
◆ Prediction
Further 3.1 alphas and betas are likely before year end, with 3.0 and 2.6 patches continuing in pairs.
