A self-hosted AI workspace with the boring parts included

What it does

DEEIX Chat is a deployable AI platform that gives teams a single interface for talking to multiple upstream providers—OpenAI, Anthropic, Google, xAI, OpenRouter, and anything OpenAI-compatible. It bundles chat, file uploads with RAG, MCP tool calling, model routing with circuit breaking, and enterprise plumbing like usage billing, subscriptions, SSO, 2FA, and audit logs into one Go backend with a Next.js frontend.

The interesting bit

The backend serves the static frontend itself, so deployment collapses into a single runtime rather than a fragile dance of separate containers. It also treats the unglamorous parts as first-class features: there is real pricing logic, per-call tool pricing, Stripe and EPay integration, and ledger snapshots, which is rare in open-source AI tooling.

Key highlights

• Single-runtime deployment: the Go binary serves the built Next.js assets, API, and auth together.
• Model routing layer with priority, weights, and circuit breaking across multiple upstream channels.
• File handling with OCR, chunking, embeddings, and semantic retrieval via PostgreSQL/pgvector or SQLite/sqlite-vec.
• MCP tool support alongside provider-native tools, with execution limits and traceability.
• Built-in billing and identity: subscriptions, top-ups, Stripe Checkout, SSO/OIDC, TOTP, and audit trails.

Verdict

Teams that need to offer managed AI access to customers or employees—and actually charge for it—should look here. If you just want a quick personal ChatGPT wrapper, this is overbuilt.
