Common questions
Is Carbon really free?
Yes. Download the launcher and use it without a subscription. Pro and Ultra are on the roadmap; we have not turned on paid plans yet.
When will Pro and Ultra be available?
We are still designing what belongs in each tier. Join Discord or follow releases on GitHub to hear when paid plans open up.
Will paid plans change what's free?
We intend to keep the launcher useful without paying. Paid tiers will add extras on top, not gate basics you rely on today.
How will billing work once paid plans launch?
We have not turned on checkout yet. When Pro and Ultra ship, we will publish pricing and payment options on this page first.
