Bottom line: Choose MonkLayer for instant visual feedback with no project setup and no per-seat bill. Choose Ruttl if you run an agency that needs project workspaces, version comparison, live CSS edit mode, and PDF/static-image annotation alongside web pages.

MonkLayer and Ruttl both annotate live websites with comments and drawings. Ruttl adds a project-workspace layer with version history, side-by-side comparison, and a "live edit" mode where reviewers can suggest CSS/text changes inline. MonkLayer is the simpler, open-source, flat-rate alternative. Link-based sharing, real-time cursors, no project hierarchy.

Ruttl is a paid visual feedback platform with project workspaces, version comparison, and live website edit mode.
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.
"Ruttl's live CSS edit mode is the standout feature; if reviewers genuinely need to suggest specific code changes, it's hard to replace. MonkLayer skips that and stays free. Most teams I talk to don't need the edit mode — they need the annotation to work in 30 seconds."
MonkLayer annotates and shares a single page free with no sign-up, charges a flat rate for team projects, and works on any webpage. Recipients of your share links don't need to install anything.
