We build client sites in Bricks and kept losing revision rounds to screenshots buried in email threads, so we built Reviso and put the free version on WordPress.org.
The short version: a client opens a review link with no login and clicks any element on the live page to leave a comment. Each comment carries an auto screenshot plus page and viewport context. When they are happy they approve the page and you get a timestamped sign-off.
The Bricks-specific parts, since this is the developers category:
Pins anchor to the rendered element rather than to coordinates, so they survive edits and reordering, and a rAF reposition loop keeps them attached on animated or lazy-loaded sections.
Suggest mode: the client proposes replacement wording on the page itself, and applying it writes back into the Bricks page content with a snapshot taken first, so every applied edit is revertable and records who applied it.
Comments, approvals and screenshots stay in your own database rather than ours.

What would be genuinely useful is compatibility feedback from anyone building client sites in Bricks, especially unusual setups: custom elements, heavy query loops, or a child theme doing something clever. Happy to answer anything here.
Disclosure: we make it. There is a paid tier for multi-page reviews and white-label, but the free version is not a trial and does not expire.
