Pastel alternative for AI-made HTML prototypes
Pastel is a feedback tool for websites: you share a page and people leave comments on the design, usually while it runs at a real URL. Ollav starts one step earlier. An agent made you a single HTML file, you upload it, share one link and collect pinned comments, and the same agent can read them and ship the next version. Checked November 2026; check each vendor's site for current details.
Who this is for
You prototype with Claude, ChatGPT, Cursor or Codex and want teammates or clients to react to a page that doesn't live on a website yet.

"Not mentioned" means we couldn't find it on the vendor's site, not that the feature is missing.
When to pick Pastel instead
- You're reviewing a real website and want feedback tied to the page as it runs, across pages and sites. Ollav hosts a file; it doesn't review your running site.
- The review is visual QA on something already built and deployed, with design and client sign-off on the live thing.
- Your workflow is a person collecting feedback, with no agent that needs to act on it.
When to pick Ollav instead
- The prototype is one HTML file an agent produced, and you want that agent to read the feedback, reply, resolve threads and publish v2.
- You want the same share URL across versions, with earlier comments kept.
- You prefer workspace-private by default: documents aren't indexed, and every reviewer signs in, so each comment has a name on it.
- You like emoji reviews: react to a comment or pin a 🔥 on the thing you mean.
FAQ
Is Ollav a replacement for Pastel?
Only for part of the job. If you're reviewing a live website, Pastel is built for that and Ollav isn't. If you're reviewing a single HTML file an agent made, Ollav is built for that.
What can I upload to Ollav?
One self-contained HTML file up to 15 MB. Inline the CSS, JavaScript and images, or load them from absolute https:// URLs. Relative asset paths and server-side code don't work.
Do reviewers need an account?
Yes. Reviewers sign in, either as workspace members or as invited guests, and guests are free. That makes every comment attributable, at the cost of one extra step.
Does the link change when I publish a new version?
No. Every version lives at the same link, and comments from earlier rounds are kept.
Can my agent act on the comments?
Yes. Through MCP or the REST API an agent can read open comments, reply, resolve a thread and publish a new version.
What does Ollav cost?
There is a Free tier and you don't need a card to start. Pro is EUR 12 a month, and Team is EUR 10 per seat a month with a minimum of 3 seats, both excluding VAT.

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