Improve your Developer Experience.
Test and measure your developer experience with on-demand feedback from Haxor developers.Learn More
We recruit developers to build with your API, SDKs, documentation, tutorials, and examples.
Recordings, metrics, surveys, and transcriptions are posted to your Haxor dashboard.
Trusted by leaders in the DevRel community .
Explore your developer experience dashboard
See your developer experience recordings in your online dashboard.
Developer tests are administrated with Paircast, a developer screencasting tool we developed to help link code changes to video.
Make data-driven decisions.
Developer experience analytics help you learn how long it takes for developers to code, what applications they use, and what they think about your product.
“I am so glad we decided to do this. Super valuable and we want to test again once we've made changes.”
Jeff DomkeHead of Product, Blockstack
“It?s incredible how many issues and opportunities developer testing found. We will be in much better shape soon.”
David BloomGM, Sterling Talent Solutions
“Developer testing is exactly what we needed. We identified blind spots in our developer sign-up and navigation and were able to make changes immediately.”
Mike StoweDeveloper Relations, Ring Central

We recruit developers to test
As developers build with your product, they record their screen, microphone, and code changes with Haxor. They narrate their thoughts along the way, letting you know what they care about and what confuses them.
Watch developers use your product
See just where things go wrong by watching your Haxor casts. See code changes, open applications, as well as transcriptions of what was said during the task.

Measure your DX
Developers speak aloud as they work and fill out a survey at the end. Learn about friction in your products on-boarding and where your code examples have bugs. Use our DX survey or use our Zapier skill to integrate your own.
20 GOTO 10
Every month we recruit new developers to try your product and record feedback. See how your developer experience changes over time and get alerted when things break.

What is a "Hello World?"
A "Hello World" is a programmer exercise that demonstrates a setup procedure. Usually, this means outputting the text "hello world" to demonstrate that the system has been set up and works.
Your product's "Hello World" is the point at which you consider your developer tool "setup." Usually this means the developer has created an account, copied their API keys, and run an example project. This demonstrates they have an understanding of your product.
What other kind of content can you test?
We can test "hello worlds," getting started, tutorials, documentation references, blog posts, GitHub readmes. If it looks like developer instructions, we can test it.
What is a "developer product"?
Developer products are APIs, SDKs, as well as desktop software, clients, etc. We have testing VMs, database software, mobile and web SDKS. Code is best, but we can test anything.
Can I specify a specific skill for developers?
You can supply both experience requirements during HelloWorld setup. We do not test on senior or expert level developers. Specialized skillsets may incur additional cost.
What if I don't like my recordings?
Just let us know. Recordings are manually reviewed and quality guaranteed.
Where do you find developers?
We hire developers from the United States who speak English. We recruit from our Developer Community, DevPort, and online freelancing websites. Developers are of entry and intermediate skill level and we pay competitive rates to make sure we have the developers' attention. Most developers are ecstatic to make money by working with a new service, and love speaking their mind!
How does the risk-free trial work?
We set you up and begin testing as we normally would with a single developer. See how the system works and get your first recording and feedback without any commitment.
If you decide to continue we'll complete the test and recruit 3 new developers monthly.
What if I want more developers?
You can configure the number of developers within HelloWorld. We recommend 5 or 10 developers to start. See this article on how many participants you should use for a UX study.
What if I want a shorter or longer test?
We recommend 2 hours as a starting point as it offers ample time to both speak aloud and debug issues. Participants typically perform slower while speaking aloud.
