How our online bug tracker works
Report bugs in three easy steps. Capture the issue on your website, add visual context and refine with AI, and send it to your existing issue tracker with the technical details attached. From there, your team can prioritize, discuss, resolve, and close it.
Capture the bug
Open the Marker.io widget to capture the affected page in one click, then highlight the issue and add any necessary details.
Add context and refine the report
Annotate the screenshot and harness AI to describe the issue. Marker.io automatically records technical details so developers can investigate.
Send it to your issue tracker
Submit the report to your connected issue tracker, where your team can prioritize it alongside existing work items in the backlog.
“Clients used to send us emails, documents, spreadsheets and even powerpoints for feedback. Now we just use Marker.io.”

Frequently Asked Questions
What is an online bug tracker?
An online bug tracker is web-based software that helps teams report, organize, prioritize, and track bugs through to resolution.
A website bug tracker is designed specifically for issues found on websites. Marker.io enables reporters to capture a bug directly on the affected page, add visual feedback, and send the report to the team responsible for fixing it.
What is the difference between bug tracking and issue tracking?
Bug tracking focuses specifically on defects – things that are broken or don’t work as expected.
Issue tracking is broader. It can include bugs, improvements, tasks, feature requests, and other work items. Marker.io supports different issue types and sends reports into the tools your team already uses to manage its backlog.
What information should a bug report include?
A useful bug report should include:
- A clear title and description.
- Steps to reproduce the problem.
- The expected and actual results.
- The affected page and environment.
- The bug’s severity or priority.
- Screenshots, recordings, and technical logs.
Marker.io captures the screenshot, page URL, browser, operating system, screen size, and other technical context automatically. Console logs, network requests, and session replays can also be included when enabled.
How do you prioritize bugs by severity and impact?
Start by separating severity from priority. Severity describes how much damage the bug causes, while priority determines how urgently it should be fixed.
Consider how many users are affected, whether a workaround exists, how often the bug occurs, and whether it blocks a launch, checkout, or other important business process. Marker.io lets teams classify issues as Urgent, High, Medium, Low, or No priority.
Can external clients report bugs without an account?
Yes. Clients, testers, and other external reporters can submit bugs through an open Marker.io widget without creating an account.
Reporters can follow up on their own submissions, while invited guests can be given access to a specific project when they need to review and collaborate on a wider set of issues.
Can Marker.io replace Jira?
Marker.io is designed to work with Jira, not replace it.
Marker.io makes it easy for stakeholders to capture visual website bugs and automatically collect the context developers need. It then sends each report into Jira, so your development team can continue managing priorities, assignments, and the backlog in its existing source of truth.
How do bug tracker templates help prioritize issues?
Bug tracker templates standardize how team members track bugs and report bugs, so every issue includes the same key features: steps to reproduce, impact, priority, and environment.
With consistent fields, which you can customize using Marker.io, your combined bug tracking system and project management tool can prioritize tasks and generate reports that separate quick bug fixes from larger feature requests, defect management or test management work.
In Marker.io’s bug tracking service, widget fields map to your issue tracker’s custom fields, so incoming feedback lands in the right list, aligning with your agile methodologies and ready for project planning, so you can start assigning tasks correctly. Setup is easy, so your company can start using Marker.io in just a few clicks. Thanks to the analytics feature, you also get key metrics and insights into team performance.
How do I build a bug tracker with JavaScript?
To build a bug tracking tool with JavaScript, you don’t need to reinvent an entire issue tracking system. Drop the Marker.io JavaScript snippet code or SDK into your website’s HTML and connect it to your favorite issue tracker or project management tool.
With a few lines of code, you get a simple bug tracking tool for issue reporting, screenshots and technical metadata. Integrations are a major component of our bug tracker: create a versatile platform for bug tracking thanks to third-party integrations with your project management, software development, CMS, and team collaboration tools.
Your connected tools handle access control, customizable workflows, time tracking, audit trails, and reporting, while our straightforward defect tracking system saves you time by capturing high-quality bug reports to get pulled automatically into those other tools – no steep learning curve or complex code review needed.
