I was very satisfied with Sizzy until the deal expired. Now, the developer is no longer responding to questions, the product is not being updated, and bugs remain unresolved. The browser engine is quite outdated and doesn't support new CSS rules, like nesting, which makes it unusable for me as a web developer. The roadmap and changelog were last updated several months ago, and there has been silence since then. The annoying bug still exists, where the dev tools always refresh when switching between tabs. The developer is aware of it but no fix so far.

I bought the product in june and never ever got any update for the browser.

Very disappointed - do not buy if it ever comes back.
