KryMark alternative for AI-made HTML prototypes
KryMark is a feedback and markup tool. We found less public detail on it than on most tools we compare, so this page sticks to what Ollav does and leaves KryMark's specifics for you to confirm on its own site. Checked November 2026; check the vendor's site for current details.
Who this is for
You build prototypes with Claude, ChatGPT, Cursor or Codex, and you want visible, pinned feedback that the same agent can act on.
Honest overlap
Both tools are about collecting visual feedback so you don't have to chase it through chat threads and screenshots. Where they differ is what gets reviewed and who is doing the commenting.

"Check the vendor's site" means we didn't want to guess, not that the feature is missing.
When to pick KryMark instead
- Its review model fits your material better, for example if you review something other than a single HTML file.
- Your team or clients already use it and the process works.
- After trying both on the same project, you simply prefer how it feels.
When to pick Ollav instead
- It's one HTML file from an agent, and you want comments pinned on the page.
- 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 signed-in reviewers, workspace-private by default (not indexed) and a Free tier with no card.
FAQ
Is Ollav a KryMark replacement?
Only if you review agent-built HTML files. Confirm KryMark's current features on its site and try both on one real file.
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 on an Ollav share?
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 (Claude, ChatGPT, Cursor, Codex) 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.
