Free for most teams. ShakaStack Pro for the rest.
ShakaPerf is source-available and trust-based. Most uses are free under The ShakaPerf License, including production use by small organizations. Larger organizations subscribe to ShakaStack Pro: one flat price per organization that includes ShakaPerf, React on Rails Pro, and Slack support from the maintainers.

Not sure which side of the line you are on? The license asks three questions about your organization, counted with affiliates: team size, revenue, and outside capital. The authoritative definitions are in LICENSE.md. When in doubt, email us and we will sort it out in one reply.
Already on ShakaStack Pro through React on Rails Pro? ShakaPerf is included for your organization (under 250 people and under $10M revenue), so there is nothing to buy here. See Free & Pro on reactonrails.com.
Prefer results over setup? ShakaCode runs ShakaPerf for you as part of a performance audit, and a subscription is never required to work with us.
Supporter memberships and sponsorships are appreciated but are not subscriptions and grant no production-use rights. Once a version ships under given terms, those terms govern that version permanently. Questions: contact@shakacode.com.
