Here is the whole thing, from both sides of the link. Your side takes two minutes to set up. Your client's side takes no set-up at all.
Paste the website URL, or drag in an image, PDF or video. HopBack loads the live site, including staging sites behind a password, and renders files at full size. This is one HopBack.
Tell HopBack how many revision rounds the project has, say three, and when you need feedback by. Both are optional. Both make the rest easier.
Copy the review link and send it however you like. Email, Slack, a text. No invitation is needed and your client is not asked to sign up.
As your client drops carrot pins, each comment appears in your sidebar the moment it is posted, tied to the exact element they clicked. Open and resolved states keep the list honest.
Reply on the pin, set a priority, tag it for whoever is doing the work, and resolve it when it is done. Filter by open, resolved or all.
Upload the revised work or point HopBack at the updated site. Rounds do not have to be the same format: a flat PNG or PDF concept in round one, the staging link in round two, all under the same link. Anything still unresolved carries forward. Compare shows round one and round two side by side.
When your client hits Finish review and approves, their name and the time are recorded, the feedback locks, and you are notified by email, or in Slack and Teams on Studio and Agency plans.
It opens in the browser. The real site, or the design, is right there. They type their name once and HopBack remembers it for the session.
They click the thing they mean, a carrot pin drops, they type. If words are not enough, they attach a reference image or a screenshot to the comment. They can switch between desktop, tablet and mobile widths, move between pages of the site, and reply on threads.
When they are done they hit Finish review and choose: Approve, or Send feedback. Then they close the tab and get on with their day.

Nothing to install on the client's site. No plugin, no snippet, no browser extension for them. Works with any site that has a URL. Notifications go to Slack and Microsoft Teams. Your AI tools can read the workspace through MCP on the Agency plan.
No. HopBack loads the site at the URL you give it. Nothing is installed and nothing changes on the site itself.
Yes. Share the same link with as many people as you like. Each reviewer types their name and their comments are labelled with it.
Add the staging password when you create the HopBack and it loads normally. Your client never sees the password.
Yes. Upload an image, a PDF or a video and the same carrot pins work on it. Logos, brochures, packaging, social tiles and video edits all work this way.
About two minutes for your first HopBack. Paste a URL, set the rounds if you want them, copy the link.
Paste a URL, send the link, and watch the first carrot pin land.
