I cofounded FeaturePeek, where we built a tool to solve this problem. It syncs comments and screenshots to the GitHub/GitLab pull request, so teammates can leave feedback during the development cycle, when devs prefer. We were acquired by Netlify in 2021, and now it’s built in to their Deploy Previews product, available on every pricing tier.
