is going to require users to have a paid account in advance of the larger beta payment migration.

Background is the most expensive service we provide to our users. It is also the most easily misused: we have, on many occasions, had to reach out to users who are not paying for their account and who are submitting an excessive number of expensive jobs.

This has been exacerbated recently with a rise in cryptocurrency mining attacks on Malicious users have been deliberately submitting huge numbers of jobs under dozens of frequently registered accounts and deliberately circumventing our abuse detection to use as much of our resources as possible to mine cryptocurrencies. This exhausts our resources and leads to long build queues for normal users.

We have a multifaceted approach to dealing with this kind of abuse. We will not go into detail in public on our anti-abuse measures: secrecy is required for them to be effective. However, one easy measure we can do to cut this abuse down substantially is to make a paid service.

All users will ultimately be expected to pay for their account (details). Making paid ahead of the rest helps to fix some problems, free up our sysadmins to focus on development, and does not substantially change the long-term planning.


All of the details in the billing FAQ apply here.

Will pricing change after the alpha?

Yes. The exact numbers have not been decided upon. There will be a generous period of consultation with the community and advance warning before any pricing changes take effect.

I'm not sure I can afford it.

It is not our intention to price anyone out of using the service. If the minimum fees are too high for your financial needs, then you can simply send us an email explaining your situation, and you will be issued free service, no questions asked. users from many walks of life have been granted free service: students, users with issues using their currency of choice, people between jobs, and so on.

I represent an organization, how do we pay for

The software implementation for user groups or organizations is prioritized for the beta. In the meanwhile, utilize any workaround you wish: nominate one of your members to host your resources on their account, or set up a dedicated pseudo-account for the organization, or any other approach that suits your needs. We will help you migrate to user groups once the feature is available. Shoot us an email to let us know about your workaround and we'll make a note on your account.

Billing considerations for organizations will be available when the beta begins, but we don't know what they'll look like yet. The final discussion is deferred pending the final software design. Don't double-charge yourself: just pay on a single account and let us know. If you set up a dedicated organization account, and one or more of your members has a paid account, let us know and we'll link the billing so that you don't have to pay twice.

What about builds submitted for patches?

Jobs submitted to run tests against patches sent to mailing lists are submitted under the project owner's account. This account is the one that needs to be paid — not the accounts of those submitting patches or pull requests.

Community discussion

The proposed changes have been put to the community for discussion, via IRC discussions in the week of 2021-04-12; in the public Mumble meeting on 2021-04-16; and on

Detailed migration plan

The plan is as follows:

  1. All new users who register on or after 2021-05-01 will be required to pay for their account to use Users registered before this date will not be affected immediately:
  2. On the same date, existing users will have 30 days to convert to a paid account before they will no longer be able to submit builds. Any non-paying users who have submitted builds during the 30 days prior to 2021-05-01 will be notified of the impending change by email, and will be given an opportunity to ask questions of the admins prior to the changes coming into effect. Users with extenuating circumstances who require additional migration time will be accomodated.
