“Clients used to send us emails, documents, spreadsheets and even powerpoints for feedback. Now we just use Marker.io.”
Record and track issues easily in your testing workflow
Keep QA moving by giving testers the simplest, most complete way to log issues: directly on the page, without switching tools.
Log issues in seconds
Click the widget, describe the bug, and submit. Marker.io handles the rest – no alt-tabbing, no manual documentation, no context lost between tester and developer.
Stay in your workflow
Every tracked issue syncs straight into your project management tool. Your QA team works in Jira, Linear, or Trello, so that's where your bug reports land.
Cover more ground fast
When reporting’s this easy, testers flag more. More issues surfaced early means fewer surprises at launch – and a more complete picture of your test coverage.
“Our developers can now see bugs through the reporters' eyes, with no information getting lost.”
Your report lands in Jira automatically
Or Linear, Azure DevOps, GitHub, GitLab, Trello, Asana, ClickUp, Monday.com, Notion, Teamwork.
All the debugging context, attached automatically

Console + network logs
Captured with every report. No asking the reporter to open DevTools.
Full environment
Browser, OS, screen size, and the exact page URL, on every single report.
Session replay

Captures everything automatically
Browser, OS, screen size, page URL, console logs, and network logs are attached to every report without the tester doing anything. Your developers have what they need from the first report.
Supports your full testing process
From exploratory testing and manual testing through to structured test cases and regression testing, Marker.io supports the entire QA cycle, not just one phase of it.
Keeps everyone in the loop
Clients, stakeholders, and external reporters stay updated through the guest portal and automatic status sync. No more chasing updates across email threads.
Set up Marker.io to catch issues at any stage
Make sure your site is ready while it's in production, or catch issues once it's live. Here are the ways you can implement Marker.io.
JavaScript snippet
Paste a single line of code into your site and Marker.io is live. It takes minutes, requires no build process, and works across web apps and multi-site environments. Once installed, the widget is available on every page so testers can report from anywhere without any additional setup.
Browser extension
Install the Chrome extension and start reporting bugs on any website – no code required. It’s the fastest way to get QA running on a live site, a client's site, or any page you don't control the codebase of. Ideal for QA engineers doing cross-browser testing or spot-checking in production.
WordPress plugin
Add Marker.io to any WordPress site directly from the plugin directory, with no developer help. The no-code installation works out of the box, making it the right choice for marketing teams, content editors, and agencies managing WordPress-based sites.
Deploy Marker in your favorite CMS
Install Marker on all existing CMS, including Wix, Shopify, Wordpress and other tools in the market. Handle issue reporting wherever you are with our QA testing tool.
Understand who is sending bug reports
Use custom metadata to get more insights into your QA tool testers and reporters.
“Our developers can now see bugs through the reporters' eyes, with no information getting lost.”
“It's very nice to limit the form. Too many fields would confuse our clients and users. Now they just have the title and description.”
Track bugs and report them on any device
Collect user feedback from team members, QA testers, stakeholders, clients, or even customers on mobile, tablet, and desktop.
Watch what happened before a bug was filed
Session replay gives QA testers and developers the full picture, not just a screenshot of the moment something went wrong.
Record every session
Marker.io records user sessions. Rewind to watch what happened before an issue was reported.
Watch what happened
See every click, scroll, and interaction in the moments that led to a bug encounter.
Give vital context
Remove the guesswork and cut the back-and-forth between testers and developers.
“I love that we get a video of exactly what happened to our users”
Collect website issues in one source of truth
Don't ask your devs to adopt a new tool. Make sure all QA tester feedback arrives where your devs work, with all the information they need to reproduce bugs.
