16 Best Website Annotation Tools

Here are the best website annotation and markup tools for 2025.

1. Marker.io

Add comments, annotations, and markups directly on your website.

Marker.io simplifies the process of taking screenshots and annotating them for your team and clients.

This functionality is particularly useful during website QA cycles:

With one click, both technical and non-technical stakeholders can share feedback and report bugs on live websites.

Marker.io is ideal for client feedback and QA testing, thanks to its on-page annotations and integrations with project management tools.

Website annotations, markups, and comments

Marker.io can be added to your website as a widget or a Chrome extension. This makes it easy to capture and annotate web pages.

Just install the code snippet or browser extension to start annotating. The tool includes:

• Full or partial annotated screenshots
• Arrows for emphasis
• Text-over-image
• Rectangle, circle & pen tool
• Blur for sensitive info
• Image overlays
• Emojis
• Color options

Marker.io is best for:

• Bug reporting and bug tracking. It helps your QA team or end-users report bugs quickly.
• Website feedback collection. It gathers client feedback efficiently after delivering a website project.

Here's how simple it is:

1. Click “Report a bug” when you spot one or have feedback.
2. Annotate and markup the page, fill in the feedback form.
3. Hit “Create issue”—and you're done!

2-way integrations

The best part about Marker.io is our deep integrations with popular project management tools like Jira, Trello, GitHub, and Asana.

Whenever your reporters submit feedback, an issue is automatically created in your chosen tool.

That’s right: you don’t need to spend hours triaging your inbox anymore. Plus, your developers can stay in their preferred environment.

When a task is marked as “Done” in your project management tool, that same task will also be “Resolved” in Marker.io.All stakeholders can see the status of reports in the dashboard.

For detailed discussions on specific issues, you can use the feedback page.

All comments and attachments sync with your project management tool.

Detailed bug reports

Asking clients and non-technical stakeholders to markup or annotate your website can sometimes lead to lost information:

• Console logs
• Browser and environment info
• Viewport details
• etc.

This can cause endless back-and-forth between developer, project manager, and reporter.

And a bunch of headaches, too!

Marker.io automatically includes essential information with every report:

• Reporter name
• Source URL
• Console logs
• Environment info
• Session replay
• Any other details developers need to fix the bug

Customizable feedback forms

QA testing involves a wide range of reporters, from your team to clients or end-users.

Marker.io offers two types of feedback forms:

• Guest Forms for non-technical users and clients
• Member Forms for your QA team

Both forms are fully customizable. This added functionality allowis for detailed feedback from your team and simplicity for clients or end-users.

Session replay

As a developer, when you receive bug reports from your clients, your first action is to try and reproduce that scenario.

But even with all the technical data in the report—you sometime still fail to understand what’s going on.If only you could see exactly what happened on the reporter’s side when the bug occurred…

Well—Marker.io's toolkit includes session replay for that reason.

Straight from your PM tool, simply click the “Watch replay” link.

You’ll then be able to watch the last 30 seconds (or more) before the report was submitted.
