Marker.io alternative for AI-made HTML prototypes
Marker.io is a bug-reporting tool for websites: a widget on your site lets testers and clients annotate a screenshot and send it, with technical context, into your issue tracker. Ollav is for the earlier, looser moment: an agent made you a single HTML file, and you want comments pinned on it before there is a site or a ticket. Checked November 2026; check each vendor's site for current details.
Who this is for
You build prototypes with Claude, ChatGPT, Cursor or Codex and want quick, visible feedback that the same agent can act on, not a QA pipeline into Jira or GitHub.

"Not mentioned" means we couldn't find it on the vendor's site, not that the feature is missing.
When to pick Marker.io instead
- You run a real website and need bug reports that land as tickets in a tracker your team already uses.
- QA and client testing need technical context with each report, which a hosted HTML file can't give you.
- Feedback should flow into an existing engineering workflow, not live in a review page.
When to pick Ollav instead
- It's one HTML file and no site, staging URL or ticket queue exists yet.
- You want the agent that built it to answer the comments and publish a new version.
- You want one stable share URL across versions, with earlier comments kept.
- You want workspace-private by default (not indexed), signed-in reviewers and a free tier.
FAQ
Is Ollav a Marker.io replacement?
Not for bug reporting on a live site, where Marker.io is the better fit. Ollav is for reviewing an agent-built HTML file with pinned comments.
Do I need a website to use Ollav?
No. You upload one self-contained HTML file, up to 15 MB, and get a share link. Inline your CSS, JavaScript and images, or load them from absolute https:// URLs.
Who can comment?
Signed-in reviewers: workspace members or invited guests. Guests are free. Documents are private to your workspace by default and aren't indexed by search engines.
What happens to the link when there's a new version?
It stays the same. Every version lives at one link, and earlier comments are kept.
Can an agent handle the feedback?
Yes. Through MCP or the REST API, an agent can read comments, reply, resolve threads and publish a new version.
What does Ollav cost?
There is a Free tier and no card is needed. Pro is EUR 12 a month and Team is EUR 10 per seat a month with a minimum of 3 seats, both excluding VAT.
