Improve your Developer Experience.

Test and measure your developer experience
with feedback from developers who build with your product.

Schedule Call

We recruit developers to build with your API, SDKs, documentation, tutorials, and examples.

Developers record themselves with Paircast as they build with your products.

Reports are posted to your dashboard every month.

Trusted by leaders in the DevRel community ?.

Gain insight from developers who build with your product.

Every plan comes with 12 Paircast sessions per month.

Paircast creates a markdown transcript of the code developers write and the things they say during their session.

Measure your Developer Experience.

Our Developer Experience Score (DXS) helps you understand developer perceptions and efficiency.

The DXS is a "Single Usability Metric" calculated from a variety of metrics we track during testing. We call this the TECH framework.

Every month we recruit new developers to try your product and record feedback. See how your developer experience changes over time and find out when things break.

Every Quarter

Measure your DX

Your DXS is made up of 4 metrics that matter most to a successful DX. We call these the TECH metrics and they work perfectly as quarterly KPIs.

How does the 7-day trial work?

We test with a single developer and send you the result. If it's not what you're looking for, we'll refund you entirely. See how the system works and get your first recording and feedback without any commitment.

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.

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!

What if I want a shorter or longer test?

We recommend a 30 minute test as a starting point. Especially difficult tests may require 2-hours. You can select your test length at checkout.

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 an additional cost.

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.
