Grengin is a free, open-source AI gateway you run on your own infrastructure, giving teams governed access to multiple LLM providers without routing data through third-party SaaS. Spin it up in under 5 minutes using a cloud marketplace image with OAuth/SSO already configured, or a guided setup wizard (4-5 steps) — no YAML wrangling, no multi-hour setup. Under the hood: department-level budgets, RBAC, MCP server integrations for tool use, semantic search across chat history, and an admin dashboard, all shipped as source you can audit, fork, or self-modify.
For sysadmins, that means real knobs: whitelist which providers/models are reachable, cap spend per department, register and manage your own MCP tool servers, and scope permissions down to the org or team level. It also ships with tamper-evident audit logs, per-user/department/model usage analytics, and SSO hooks for Google and Azure AD — the stuff you'd otherwise have to bolt on yourself with a commercial alternative.
