Frequently Asked Questions
What is a website annotation tool?
A website annotation tool allows users to annotate web pages and web applications directly in the browser, instead of sending separate screenshots over a separate communication platform. You open a page or live website, click a button or feedback widget, and then annotate the webpage with comments, highlights and other notes.
These tools help turn abstract website feedback into visual feedback, providing clear context to developers and designers so they can understand it in terms of what’s on the page.
A good website annotation tool captures contextual feedback: which page you were on, the browser and device, and sometimes more detailed information like console errors, which makes reviewing websites and debugging smoother for everyone on the team.
Because the annotation happens right on live sites on those in production, you don’t need specific technical skills to provide feedback – users just click, take a screenshot, annotate it, and share their feedback.
What is the best website annotation tool?
There isn’t one website annotation tool that works for everyone; the right annotation tool depends on your feedback process, your industry, your existing tech stack and your budget.
Some teams benefit from deep collaboration features with tight links to their existing project management tools – for example pushing website feedback into a kanban board or syncing comments into a project management tool. Others get more from simpler tools where users only need to be able to open a browser extension, annotate, and share a link.
You’ll want to compare integrations, how people capture feedback, automation and AI features, collaboration and stakeholder management solutions and, of course, pricing and plans
Many tools offer a free trial or free plan, a starter level, and a premium plan for when you grow to the next stage.
Why should you choose Marker.io?
Marker.io is particularly strong if you want one tool focused on website annotation across live sites and those in production, with the option to install a feedback widget and a Chrome extension to capture contextual feedback and send it straight into project management tools.
It’s built for web development teams and developers who need annotated screenshots, smart annotations, session replay and two-way integrations with their existing workflow, rather than a generic markup hero–style tool for static files only.
How do I get started with Marker.io’s website annotation tool?
1. Sign up and pick a plan: Sign up for a Marker.io account, start on a free trial on our basic plan, and upgrade to a premium plan later if you need more projects, users, pages, or advanced collaboration features.
2. Install the widget or browser extension: Add a lightweight script tag or JavaScript SDK to your website so the feedback widget appears on live sites, proxy version environments, and staging web pages, or install the Chrome extension to start annotating any web page or web applications without needing to use code.
3. Connect your project management tools: Link Marker.io to your existing project management tools so website feedback flows into the right workflows.
4. Invite your team and collaborators: Invite your team, developers, clients, students and other users so everyone can provide feedback, share ideas and comment directly on the page.
