Roundmark

Design feedback from clients arrives as annotated screenshots, marked-up PDFs and 'the button on the left, no, the other left' emails. Existing tools either cost too much for small studios or stop at static images.

We wanted a client to click the live site itself and have the comment land exactly there, on the right viewport, in real time.

Roundmark loads a live URL in an iframe, or falls back to a Playwright-captured full-page screenshot when a site refuses to be framed, and stores every pin as viewport percentages so comments survive any screen size. A BullMQ queue handles screenshot capture and PDF exports in the background, real-time delivery runs over server-sent events backed by Redis pub/sub, and reviewers get in through passwordless magic links with mentions and threads. Per-viewport tabs, version history and screen approval with progress complete the loop.

The product went from first commit to a live, rebranded release in three weeks. It runs at roundmark.it with a free tier, Pro at $15 and Agency at $39 per month, 14-day trials included, billed through Stripe. We put our own client reviews through it, which is the fastest feedback loop a tool can get.
