Goodbye Flash! Cacoo is migrating to HTML5

A big change is coming to Cacoo: we’re ditching Flash for HTML5.

Since Cacoo was created in 2009, we have been using Flash for our editing interface. At one time, it was incredibly popular for its ability to enable advanced graphical expressions on the web unaffected by a user’s operating environment.

Nowadays, there are a lot of concerns surrounding security. Meanwhile, HTML5 has grown in its ability to encode rich graphics, and it has slowly overtaken Flash in the market.

In response to the changing technological landscape, the Cacoo Development Team has decided to migrate over to HTML5.

Migrating to HTML5

Revamping this core feature is no easy task. Consequently, some users may worry about how this change will affect their Cacoo experience. As we take on this challenge, we promise our users the following:

  1. We won’t disable any of our current key features. The parts of Cacoo that you know and love are coming with for the ride.
  2. We will continue to provide you with great features, templates, and shapes for creating clean, professional diagrams.
  3. We will never stop trying to improve our product.

You can expect huge improvements in performance. And as always, we will continue to develop new features, resolve issues, and improve the user experience.


For those of you eager to try out the new interface, keep an eye out for the release of our beta version.

At this point, we don’t have an exact delivery date for the new intervface. will deliver this new editing interface, but we will inform you of updates as they come, so please keep checking our blog for updates!
