Pricing FAQ
Yes — forever. The Community edition is the full unified engine as a single
self-hosted binary, free for individuals and teams. There is no time limit and no usage clock; you
run it on your own infrastructure.
Entirely on your own infrastructure. GreyCat runs as a self-contained
binary on your hardware, and AI runs on-device so prompts and documents never leave
your deployment. GreyCat is built by DataThings in Luxembourg (EU).
Pro is for teams shipping to production: it adds Pro
libraries, enterprise connectors, OIDC single sign-on, monitoring & profiling, live and delta
backup, higher worker/cache limits, and email & priority support. Enterprise is
for regulated and large-scale deployments: it adds uptime SLAs, EU-sovereign / on-prem / air-gapped /
BYO-cloud deployment, dedicated support & onboarding, a security review and custom terms.
Pricing for Pro and Enterprise depends on your deployment, scale and
support needs, so we tailor it to you. Talk to us and
we'll put together a quote.
