Deploy Coai in one click installation.
Self-hosted AI aggregation platform unifying OpenAI, Claude, Gemini, and 20+ providers with multi-user management and usage quotas.
What you can build with Coai
Coai (Chat Nio) is an open-source AI aggregation platform that brings OpenAI, Anthropic Claude, Google Gemini, Azure OpenAI, Baidu ERNIE, Alibaba Qwen, and 20+ other language model providers behind a single hosted interface. It goes beyond a simple chat UI by adding subscription tiers, per-user token quotas, API key issuance, and usage billing — making it practical for teams that need to offer controlled LLM access to multiple users without exposing upstream provider keys.
Self-hosting Coai on your own VPS gives you complete control over which models are available, how much each user tier can consume, and what your total API spend looks like — without paying per-seat fees to a managed aggregation service.
Key features of Coai
Multi-provider aggregation
Connect OpenAI, Claude, Gemini, Azure, Baidu ERNIE, Alibaba Qwen, and 20+ providers through one platform and let users switch between them from a single interface.
User subscription tiers
Define free and paid subscription plans with per-tier token quotas, controlling how much each user group can consume across all configured providers.
API key issuance
Issue API keys to your users so they can access configured models programmatically — without ever exposing your upstream provider credentials.
Usage and billing tracking
Monitor per-user token consumption and estimated costs in real time, with configurable limits to prevent unexpected budget overruns.
Model marketplace
Users discover and select from all configured providers through a built-in model picker, with support for function calling and image generation where available.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
