18 Best User Acceptance Testing (UAT) Tools in 2024

When you deliver websites or software for dozens (or hundreds!) of clients, user acceptance testing can get tricky.

These tools helped us reduce user feedback down to a manageable amount, and always ensure our software fit business requirements.

Let’s get to it.

What is user acceptance testing?

User acceptance testing is a phase of a web project life cycle where your ideal customers test your app or website in a production-like environment.

It’s the phase after your internal QA testing and before you push your site to everyone and a staple in agile software development teams.

18 Best User Acceptance Testing (UAT) Tools

Here are the 18 best user acceptance testing (UAT) tools in 2024.

1. Marker.io

Get website feedback directly into your favorite tools and perform UAT testing without leaving your website or web app.

Great UAT tools should have:

• An easy-to-use, “one-click” system for end-users to report bugs and give feedback
• Screenshots and annotations to make reports as actionable as possible
• Automatic capture of environment info and console logs
• Deep integration with your existing PM tools (Jira, GitHub, Trello…)
• Support for alpha testing and beta testing test cases

Now for the good news: Marker.io does it all.

Visual annotations

On the tester side, reporting a bug with Marker.io is a 3-steps process:

1. Find a bug, and click the button.
2. Fill out a report and input details.
3. Click on “Create issue”—done!

It’s that simple. Check it out in action:

The editor has plenty of tools to help make the screenshot more visual:

• Arrows
• Text
• Shapes
• …emojis even!

During software testing, users must be able to visually convey what they mean—Marker.io helps do this with powerful annotations.

Detailed bug reporting and test case management

User acceptance testing involves many non-technically savvy reporters. Because of this, the quality of bug reports tends to suffer:

• Missing fields
• Wrong category
• No attached screenshot
• No environment info
• No metadata
• …etc!

It’s a real headache for developers to try to reproduce bugs without this information.

With Marker.io, all technical data is automatically captured with the bug report and sent directly to your PM tool.

This is a big time-saver for us, as we no longer need a “feedback person” to:

• Look at every report
• Categorize it
• Transfer it into our PM tool or delete it

When it comes to UAT testing, this also saves us tons of time:

• We create UAT test cases ahead of time in Jira, with a Pass/Fail field for each report
• Feedback forms from Marker.io automatically include those fields
• The end user simply needs to choose from one of the fields and click "Create Issue"

2-way integrations

As a project manager, you have two main concerns when it comes to communication with the client:

• Clients and end-users need to be notified when their issues have been resolved
• Developers should never leave their PM tool

This is only possible with Marker.io.

As soon as an issue is “Done” in, say, Jira—that same issue will also be marked as “Resolved” in Marker.io.

Check it out:

You no longer need to have an endless back-and-forth with your clients about which issues are resolved and which still need a bit more work.

Moreover, all comments left by your clients on Marker.io will automatically be synced with the issue in your PM tool (and vice-versa).

Now, your PM tool is your only source of truth: if the issue doesn’t exist there, then it doesn’t exist at all!

External and internal feedback forms

For the end-user, reporting bugs and feedback should be as simple and frictionless as possible.

But when you do internal QA, you’d want to collect as much information as possible from people who are already familiar with your app.

With Marker.io, you get the best of both worlds: Guest forms (for UAT testing) and Member forms (for internal quality assurance).

Using the guest form, your testing team, clients, and UAT testers only have to type in what went wrong. Their screenshot is automatically attached.

The member form is a bit more advanced. You can immediately label bug reports or assign issues to a team member.

These forms are also 100% customizable, which means that every time we do a new round of feedback and for every iteration, we can add, remove, or adapt fields to ask our users exactly what we want from them.

Session replay

As a developer, when you receive feedback from real-world scenarios, your first action is to try and reproduce that scenario.

But even with all the technical data in the report—your development team sometimes still fails to understand what’s going on.

If only you could see exactly what happened during end-user testing...

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 is submitted.

Check out session replay in action:

We can clearly see this user journey during the UAT process:

1. Clicked on "About Us"
2. Scrolled down & up
3. Tried several times to click on "Contact Us"
4. Gave up and reported a bug with the Marker.io widget.

Make sure the Marker.io widget is embedded on the website(s) or app(s) you are working on, and enable session replay in your widget settings. It’s as simple as that! 

Marker.io's pricing ranges from $39/mo to $159/mo, with tailor-made plans for Enterprise deals.

Frequently Asked Questions

What are user acceptance testing tools?

User acceptance testing tools help you zoom in on a user's journey during alpha testing or beta testing.

They assist you during the user acceptance testing process and uncover usability as well as functional issues.

Although there is an overlap, UAT tools are not usability testing tools:

• Usability testing is about making sure testers can complete tasks without being hindered.
• User acceptance testing is about observing real users and figuring out if they are satisfied with the new feature/product.

What are the different phases of UAT?

It is important to understand that UAT only occurs after internal QA. Terms and definitions are blurry and used interchangeably across companies.

With that said, the different phases of UAT are:

• Internal user acceptance testing. Have your non-techy coworkers and business stakeholders try out the product and business processes.
• External user acceptance testing, or alpha testing. There, friends and family members test the product.
• Beta testing. Actual users or potential users carry out the testing.

What are the different types of testing for UAT?

There are a lot of different types of testing and methodologies you can carry out during UAT:

• Functional testing
• Integration testing
• Unit testing
• Automated testing
• System testing
• Validation testing

For all of these, you’ll need strong test management tools—all of which have been outlined in our list.

What is a UAT test plan?

A UAT test plan is a set of test cases used during UAT testing:

1. Identify test scenarios and business objectives
2. Create UAT test cases
3. Execute test cases during internal UAT or with a set of beta testers
4. Gather test data, and iterate

If you need a template for a UAT test plan or for your test cases (whichever PM tool you prefer using), check out our user acceptance testing templates.

How do you create UAT test cases?

Since most project management tools do not have test cases as a feature, you'll have to create your own system.

Typically, this involves custom fields and forms to ensure you gather all the data you need for your testing process:

• Summary
• Test case steps
• Test case expected results
• Pass/Fail custom field

We've written a tutorial for creating test cases in Jira—it should be similar (and easier!) for other tools.

What is a UAT environment?

Your UAT environment is a staging environment for public testing purposes—and therefore perfect for UAT execution.

It should closely mirror your production environment. Don’t fall into thinking, “Well, this is just another testing environment. It doesn’t need to be perfect”.

The reason is simple: with an accurate clone, if something doesn’t work in staging, it won’t work in production either.

So there you have it: a list of the 18 best UAT tools out there.

We hope we helped you make a decision in choosing a tool for your next user acceptance tests—and ensure sign-off for production!
