Volley vs MarkLayer: a free Volley alternative
MarkLayer and Volley both collect visual feedback on websites, including staging sites and pages behind logins, but they capture fundamentally different things. Volley takes a screenshot first, then layers pinned comments onto that static image. MarkLayer skips the screenshot and overlays the live page directly, anchoring each annotation to the real element underneath it.
That one mechanical choice decides what each tool is actually good at. A screenshot can never change out from under a reviewer mid-conversation, which is genuinely useful for a formal sign-off: everyone comments against the exact same frozen frame, and there's no ambiguity about what state the page was in. The cost shows up the moment the page ships an update: the capture is now a picture of a page that no longer exists, and every pin on it is annotating history.
Live-page annotation trades that stability for durability across changes. A MarkLayer pin tracks the actual element, so it survives a copy edit or a minor layout shift that would silently orphan a screenshot-based comment. For a fixed review round meant to be archived exactly as-is, Volley's model is arguably the more honest artifact. For an iterative back-and-forth where the page keeps moving, which is most day-to-day feedback, live annotation is the one that doesn't quietly go stale.
Choose MarkLayer for free annotation on the live page itself, with real-time cursors and an open-source codebase. Choose Volley if you prefer screenshot-anchored feedback with Jira/Trello export and your team fits the $29/month Pro plan.

About Volley
Volley is a screenshot-based website feedback tool that layers pinned comments on a capture of the page, with Jira, Trello, and Slack export.
About MarkLayer
MarkLayer is a free, open-source web app for annotating any live webpage. Paste a URL atmarklayer.app and draw, comment, arrow, or highlight directly on the page in your browser — no install, no account, no sign-up. Share a single link and anyone can open the annotations in any browser. A free Chrome extension is available for the sites the web app cannot embed, such as pages behind a login, but it is optional and never required to view a share link. There is no paywall and no trial period.
Volley's screenshot model has one real advantage: the capture can't change under the reviewer. The cost is that it goes stale the moment the page updates. MarkLayer anchors annotations to the live element, so the pin survives a deploy instead of pointing at an old picture.
When to choose MarkLayer
- You want annotations that stay attached to the element after the page updates, not a stale screenshot.
- You want zero cost with no trial clock.
- You need real-time review with live cursors, or voice, on the same page.
- You want an AI coding agent to work through the feedback via MCP.
When to choose Volley
- You want each review round frozen as a fixed capture that can never shift.
- You want an embeddable widget so customers can leave feedback inside your own product.
- Your team already runs on Volley's project structure and the $29/month fits.
Frequently asked questions
- Is MarkLayer a free Volley alternative?
- Yes. MarkLayer covers visual feedback on any webpage for free with no trial period. It files a single thread as a Jira, Linear or GitHub issue or a Trello card, one way, and posts new comments to Slack, but nothing syncs back.
- Does Volley have a free plan?
- No permanent free plan as of August 2026. Volley offers a 30-day trial, then Pro at $29/month (discounted from $49) with 25 projects and unlimited users, plus a custom-priced Enterprise tier.
- Screenshot-based or live-page annotation: which is better?
- Depends on what you review. A screenshot freezes the state, which is useful for sign-off records but goes stale after every deploy. Live-page annotation follows the element through changes, which fits iterative work. MarkLayer is live-page; Volley is screenshot-based.
- Do reviewers need to install anything for either tool?
- No on both sides. Volley invites guest reviewers by link. MarkLayer share links open in any browser, and creating annotations needs no install either — paste a URL at marklayer.app.
- What actually breaks when a screenshot-based review goes stale?
- The pin still points at a coordinate on the old capture, but the live page has moved on. A comment about a button that sat at a certain position now floats over whatever happens to render there after the next deploy, and someone has to manually figure out which element it originally meant. MarkLayer's annotations anchor to the element itself, via its selector, so a pin survives a layout shift instead of quietly pointing at the wrong thing.
