Klickback vs MarkUp.io —
A Better Alternative
MarkUp.io is a versatile feedback tool that supports websites, PDFs, images, and video. It is a good product for teams that need to annotate many file types. But if your primary need is website feedback, MarkUp.io comes with a significant drawback: it requires your clients to create an account. Klickback does not.
The login problem
MarkUp.io requires reviewers to sign up for an account before they can leave feedback. For your tech-savvy colleagues, this is not a big deal. But for clients — especially those who are not comfortable with digital tools — being asked to create yet another account is friction that slows down your review process. Some clients will simply not do it and resort to sending feedback via email instead.
Klickback takes the opposite approach. Share a link. Your client opens it. They click and comment. No account, no password, no verification email. This zero-friction approach means you actually get the feedback you need, when you need it.

For freelancers watching their expenses, this adds up to meaningful savings over a year.
When to choose MarkUp.io
MarkUp.io is a good choice if you need to collect feedback on multiple file types — PDFs, images, videos, and websites. If your workflow involves reviewing design comps, documents, and live sites in a single tool, MarkUp.io's versatility is valuable. It is also a good fit if your reviewers are internal team members who do not mind creating accounts.
When to choose Klickback
Choose Klickback if your primary need is website feedback and your reviewers are external clients. The no-login requirement is a game changer for client-facing workflows. Combine that with lower pricing and a free plan, and Klickback is the clear choice for freelancers and small agencies focused on web projects.
