Looking for an AnnotateWeb alternative? AnnotateWeb is already free, so the question is usually: which free webpage annotation tool fits my workflow better. Multi-language and bookmarklet-based with a 2-minute session (AnnotateWeb), or extension-optional with threaded comments and 90-day retention (MarkLayer)? Below are the strongest options as of September 2026.
The honest starting point is that AnnotateWeb and MarkLayer agree on the thing that matters most: nobody, sender or reviewer, should have to install anything or make an account to leave a comment on a webpage. Both deliver on that. Where they diverge is what happens to the annotation after the tab closes.
AnnotateWeb treats a session as disposable: it runs the page through Surfly's Webfuse proxy, and the whole thing deletes itself after two minutes of inactivity. That's fine for a single quick note read within the same sitting, and genuinely useful if your team needs the interface in one of AnnotateWeb's eight supported languages or wants a one-click PNG export. It stops being fine the moment a review needs to survive a lunch break, let alone a weekend.
The other four options below are the paid route, each replacing a different piece of what a 2-minute session can't do: persistent projects, version history, a live CSS edit mode, or an agency-grade review workflow. Hypothesis sits apart from all of them, since it annotates text in documents rather than a live page's UI at all.
MarkLayer is the strongest AnnotateWeb alternative if you want threaded comments, multi-page projects, 90-day retention (vs AnnotateWeb's 2-minute cleanup), and an open-source codebase. Hypothesis is best for scholarly text annotation. Markup.io and Pastel are paid options with deeper agency workflow features.
| Option | Price | Best for |
|---|---|---|
| MarkLayer | Free. No tiers, no seats | Anyone who needs persistent visual feedback workflows. Design review, QA, client feedback, remote teams. |
| Hypothesis | Free | Researchers, students, and educators annotating articles or papers as text. |
| Markup.io | No free plan. Pro $79/month (unlimited users, 1 workspace); 14-day trial | Agencies that want managed project workspaces and version tracking. |
| Pastel | Free plan (1 user, 1 canvas); Pro $29–35/month; Team from $99/month + $24 per extra seat | Agencies running structured client review cycles. |
| Ruttl | Freemium with project limits; paid plans per user | Agencies needing version comparison and live edit mode alongside annotation. |
Free and open source, with nothing to install: paste a URL at marklayer.app and annotate the live page in your browser. Drawings, threaded comments with priority and status, arrows, highlights, and real-time live cursors, bundled into multi-page projects rather than one session per page. Share links last 90 days from last access instead of AnnotateWeb's 2-minute cleanup, and any comment or view resets that clock. An optional Chrome extension covers pages AnnotateWeb's proxy can't reach, like sites behind a login.
A free, open-source W3C-standard text annotation layer for highlighting and commenting on articles and PDFs, not for drawing on a live UI. Best for scholarly research, academic reading, and teaching, where the object being annotated is a document rather than a webpage's layout or a button.
Ceros' project-based feedback platform, run as a persistent team account rather than a one-off session. No free plan since 2025; Pro is $79/month for unlimited users in one workspace. Works as a web app with no extension required, closer to AnnotateWeb's install-free model than to MarkLayer's optional extension.
A paid, agency-grade visual feedback platform with branded review canvases, version tracking, and Slack, Trello, Asana, and Jira integrations. The free plan caps at 1 user and 1 canvas; Pro starts at $29/month.
A freemium visual feedback platform with project workspaces, version comparison, and a live CSS edit mode that lets a reviewer suggest an inline style or copy change directly on the page, a feature none of the free tools here replicate.
Paste any URL at marklayer.app and annotate the live page in your browser. No install, no account, no sign-up. Recipients of your share links don't need to install anything either.
