Grengin
Grengin is an open-source (Apache 2.0), multi-model AI platform for organizations that want their teams using AI without losing control of data or spend. One branded chat workspace connects to OpenAI, Anthropic, Google Gemini, Mistral, Amazon Bedrock, and more, while admins keep SSO/SAML/OIDC, department budgets, PII detection and redaction, role-based permissions, and exportable, SIEM-ready audit logs — the same governance layer on every deployment path, with no features held back.
Run it however fits: self-host free from source or a one-click AWS Marketplace image using your own provider keys, or let Grengin run it for you on Grengin Cloud, free for up to 10 users and $1.25 per active user/month after that — never a markup on your model bill. Every path shares the same codebase and data schema, so one-click export means switching later breaks nothing.
