Looking for a MarkUp.io alternative?

Shiproom is currently free to use for visual feedback on locally running web applications. MarkUp.io is a visual commenting platform for websites and 30+ file types—images, PDFs, videos—where teams upload or open content and leave contextual comments. They overlap on website annotation and guest review. The difference: MarkUp.io is a general creative-review workspace; Shiproom is a developer-oriented localhost review session that captures technical context and exports it for implementation.

Shiproom is currently free to use.

Early-access limits: 3 projects, 100 stored feedback items, 30 days of feedback history. Reviewers invited by link need no Shiproom account.

Where Shiproom and MarkUp.io overlap

Both support contextual comments on websites and sharing with guests who may not need full accounts.

The workflow difference

MarkUp.io centers on creating MarkUps of websites and files inside its collaboration workspace (plus a Chrome extension). Shiproom centers on `npx shiproom@latest live`: share the running local app, annotate the live UI, and export deterministic Markdown/JSON—including MCP access—without permanently hosting the app.

See how Shiproom returns visual feedback to a coding agent.

Questions about MarkUp.io alternatives

Is Shiproom a free MarkUp.io alternative?

Shiproom is currently free to use and can substitute for MarkUp.io when the job is visual review of a live local web app—not when you need multi-file creative review across PDFs and videos.

Does Shiproom work on localhost?

Yes. Start your app, run npx shiproom@latest live, and share the private reviewer link. The session serves only while the local app, CLI, computer, and network stay available.

How is Shiproom different from MarkUp.io?

MarkUp.io is a visual collaboration workspace for websites and many file types. Shiproom is a private review link for a locally running web app that captures developer-oriented context and exports it for implementation.

Give your coding agent the screen context

Shiproom is currently free to use. Copy the prepared prompt so your coding agent can start the local app, open Shiproom, wait for the private review link, and return it to you.

Read the prompt it copies

Set up a Shiproom review link for this app so I can share it.

Do all of it yourself, end to end:

1. Start the app locally if it is not already running.
2. In the project folder, run: npx shiproom@latest live
3. If it asks which port, use the one the app is running on.
4. The first run opens a browser sign-in. Tell me exactly what
   to approve, wait for me, then carry on.
5. Wait until the session is live and the private review link
   has been printed. Do not guess the link.
6. Reply with that link on its own line, and confirm it opens
   in any browser with no account and no install.
7. Keep the session running until I tell you to stop it.
8. Do not change any of my code while the review is open.

If anything fails, tell me what happened in plain language and
what you need from me.

Prefer the terminal?

$npx shiproom@latest live
