Yes. MonkLayer covers the core Markup.io use case (visual feedback on live websites), and the clients you send it to never need an account or a seat. It does not replace Markup.io for teams that need project-level workflow tooling.

Does MonkLayer have a free tier?

Do recipients need to install MonkLayer to view annotations?

No. Share links open the annotated page in any browser. The Chrome extension is only required to create annotations, not to view them.

Markup.io vs MonkLayer

Bottom line: Choose MonkLayer for fast, sign-up-free visual feedback on any live page with real-time live cursors. Choose Markup.io if you need persistent project workspaces, version tracking, and a team account tied to client deliverables.

MonkLayer and Markup.io are both visual feedback tools for live websites. The core difference: MonkLayer marks up any page in real time, bills one flat rate for the team, and needs no sign-up from the people reviewing, while Markup.io is a web app that organizes feedback into project-based reviews tied to a team account.

About MonkLayer

MonkLayer is an open-source annotation workspace and Chrome extension that lets you annotate any live webpage with drawings, comments, arrows, and highlights, then share a single link so anyone can view the annotations without installing anything. Reviewers never need an account, and pricing is flat-rate rather than per seat.

"Markup.io and Pastel share a parent company — they're built for agency client review with paid project workspaces. I built MonkLayer for the case where you just need to drop an annotation on a page in ten seconds, no signup, no project setup."
— MonkLayer, MonkLayer developer
