Frequently Asked Questions

Should you have any questions not covered here, you can always reach out to [email protected] or on Twitter @getOtterwise and we will do our best to help you out.

Do you access my code in any way?

We do not access, store or modify your code, in any way.

In fact, by default, our servers are not able to access repository code.

By utilizing GitHub annotations and downloadable coverage files, we can offer all the functionality expected of a code coverage service, without ever accessing source code.

Your organization can opt-in to permit code access, which will render code coverage per-line inside OtterWise when enabled.

Which Coding Languages are Supported?

OtterWise is language and framework-agnostic, it can be used with any coding language. The only requirement is that your code is hosted on and that your test framework is capable of outputting a Coverage Clover XML file.

Most test frameworks have this capability, for example PHPUnit has it built in (requires PCOV or XDebug), and in JavaScript you can get it through istanbuljs/nyc. We have guides as you set up your repository, to help you get started.

What are the billing commitments?

We have no minimum commitment. You can cancel anytime through your account, and we will stop billing you immediately, you will continue having access to your service until the end of your billing cycle.

At the end of your billing cycle, we will downgrade you to the free plan and automatically adjust the service accordingly, such as disabling collaborators that exceed the free plan limit. Your will still have access to your data!

What about Public Repositories?

Public repositories have no restrictions, and can have unlimited uploads and collaborators. Even with a Team plan, you still can have outside collaborators submit builds towards your public repositories, without paying for extra seats.

Do you offer a trial?

Our free plan is free forever, and offers up to 2 collaborators (yourself + one other person) without adding credit card. This will let you get setup, try out the service and decide if you want to upgrade for the rest of your team.

Can I switch between yearly/monthly billing?

Yes absolutely. Please reach out to us at [email protected] and we will get it sorted for you.

Do you offer refunds?

Yes, we offer a no-questions-asked refund policy. Please reach out to us at [email protected] and we will get it sorted for you.
