# 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.

## Side by side

| | Ollav | Marker.io |
|---|---|---|
| What you review | One self-contained HTML file (up to 15 MB), uploaded | Your own website, via an embedded widget |
| Needs a deployed site | No | Yes |
| Feedback style | Pinned comments, emoji reactions, emoji pins | Annotated reports sent to your issue tracker |
| Reviewers | Signed-in: workspace members or free invited guests | Check the vendor's site |
| New version, same link | Yes, earlier comments kept | n/a (you review the live site) |
| Agents read, reply, resolve and publish a new version | Yes (Claude, ChatGPT, Cursor, Codex via MCP/REST) | Not mentioned on the vendor's site |
| Default visibility | Private to your workspace, not indexed | Depends on your site |
| Pricing | Free tier (no card), Pro EUR 12/mo, Team EUR 10/seat/mo (min 3 seats) | Check the vendor's site |

"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 {#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.

## Try it

Upload a file, share the link and see what comes back. The Free tier, no card needed, covers a real review round.
