Manifest FAQ
Can we run Manifest on our own servers?+
Yes – the Free plan can be self-hosted via a Docker image under an MIT license with no request limit and no data leaving your network.
Do you take a cut of our token spend?+
No. You provide your own provider keys and pay the providers directly; Manifest does not mark up tokens on any plan.
What does Enterprise add over Pro?+
Enterprise adds multi-seat team management, SSO/SAML, audit logs, custom data retention, SLA guarantees and dedicated support.
Can you deploy and run it for us?+
Enterprise customers can get initial deployment assistance and ongoing support via Slack; otherwise you can use Manifest Cloud.
