Looking for a Marker.io alternative?

Shiproom is currently free to use for visual feedback on locally running web applications. Marker.io is a website feedback, bug reporting, and UAT tool with annotations, screenshots, and advanced technical metadata. The overlap is visual bug reporting on live pages. The workflow difference: Marker.io typically embeds a widget or uses a browser extension on sites you control, while Shiproom turns the app already running on your machine into a private review link for the session.

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 Marker.io overlap

Both capture visual website feedback with screenshots and environment details so developers can reproduce issues with less back-and-forth.

The workflow difference

Marker.io is built for teams shipping and maintaining websites—widget or extension reporting, issue tracking, and two-way integrations into tools like Jira. Shiproom is built for reviewing a localhost app privately, then exporting structured context for a developer or coding agent. Marker.io’s help center also documents localhost screenshot limitations when server-side rendering cannot reach local assets.

See how Shiproom returns visual feedback to a coding agent.

Questions about Marker.io alternatives

Is there a free Marker.io alternative?

Shiproom is currently free to use and overlaps with Marker.io on visual website feedback and technical context capture. Marker.io does not list a permanent free plan; paid plans start at $39/mo with a 15-day trial that needs no credit card. Choose based on whether you need Marker.io’s widget/UAT/session-replay workflow or Shiproom’s localhost review and export path.

Is Shiproom free?

Yes. Shiproom is currently free to use, with early-access limits of 3 projects, 100 stored feedback items, and 30 days of feedback history.

Does Shiproom require reviewers to install anything?

No. Reviewers open the private invite link in an ordinary browser. There is no extension, desktop app, or account required for invited reviewers.

Does Marker.io work on localhost?

Marker.io documents localhost use. Their help center notes that server-side screenshot rendering and session replays can have trouble with local assets; they recommend the browser extension or native browser screenshot APIs for localhost captures.

How is Shiproom different from Marker.io?

Marker.io focuses on website feedback and bug reporting via widget or extension, with issue tracking and integrations. Shiproom focuses on private visual review of a locally running app, capturing contextual evidence and exporting it for implementation—including through @shiproom/mcp.

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

Open the console
