Redline is a design annotation and client feedback tool built for individuals who can't justify another high monthly bill for a feedback tool. Paste your staging URL, share a review link with your client, and they can drop pins directly on your design with their feedback, no login required. When they're happy they hit Approve and you have an official sign off. No more vague emails, no more chasing feedback, no more "can you make the blue more blue-ish."
