PH Agent Hub — Multi-Tenant AI Platform
A modular, open-source AI platform with a Chat UI for users and an Admin UI for managing models, tools, tenants, and users. 🎓 MIT License • 💻 Self-Hosted • ☁️ Cloud Hosted
🚀 Key Features
Everything you need to run your own AI platform.
🏢 Multi-Tenant
Isolated tenants with their own users, models, tools, and data. Perfect for agencies and teams.
🔑 BYOK (Bring Your Own Key)
Use your own DeepSeek, OpenAI, or Ollama API key. You control your AI costs — we never bill for tokens.
🧩 Modular Tools
Web search, Wikipedia, ERPNext integration, RSS feeds, file discovery — extensible tool system.
🧩 Embeddable Widget
Embed the chat widget into any website. Customizable branding, streaming responses.
⚡ Why PH Agent Hub?
PH Agent Hub isn’t just another AI dashboard. These built-in features set it apart from Dify, Onyx, and other platforms:
🎯 DeepSeek Stabilizer
Native reasoning strip parsing, automatic JSON repair, and intelligent retry orchestration. DeepSeek models are powerful but occasionally produce malformed output — our stabilizer layer catches and fixes it before you ever see it.
🧠 Microsoft Agent Framework
Built on the Microsoft Agent Framework runtime for production-grade agent orchestration. Leverage Azure AI agents, Copilot Studio connectors, and the full Microsoft AI ecosystem — no other self-hosted platform offers this out of the box.
🔀 Session Branching
Edit previous messages or regenerate responses without losing history. Explore different conversation paths in parallel — ideal for debugging prompts, refining agent behavior, and comparing responses side by side.
🔍 File Uploads + RAG Search
Upload documents, PDFs, and text files to any session. The agent automatically retrieves relevant context using built-in Retrieval-Augmented Generation — no third-party vector database or separate pipeline required.
These aren’t bolt-on features. They’re built into the platform from day one.

Trusted by Teams Worldwide
From small businesses to established enterprises — see how organisations use PH Agent Hub to power their AI operations.
PH Agent Hub allowed us to quickly create isolated AI environments for different departments in our construction company — one for customer inquiries about our prefabricated homes, another for internal project management support. The multi-tenant setup is seamless, and having each tenant use their own API key means we control our AI costs independently.
We use PH Agent Hub to power AI-assisted customer communication on our agricultural website. The ability to embed the chat widget directly on optimuslandcy.com and have it respond to customer questions about our Cyprus potatoes has been a game-changer for our small team. The platform is lightweight, reliable, and easy to manage.
As a physiotherapy practice, we needed an AI solution that respects patient privacy and runs on our own terms. PH Agent Hub's self-hosted model means patient data stays on our infrastructure, while the AI assistant helps patients book appointments and get answers to common recovery questions. It's professional, secure, and our patients love it.

❓ Frequently Asked Questions
What is BYOK?
BYOK means ‘Bring Your Own Key.’ You use your own API keys for AI models (DeepSeek, OpenAI, Ollama, etc.). PH Agent Hub never charges for AI tokens — you pay your AI provider directly.
Can I try before buying?
Yes! Visit our live demo at agent.kainotomo.com/demo to explore the Admin UI and Chat UI with full functionality.
What happens when my license expires?
Your existing tenants remain untouched. You simply won’t be able to create new tenants beyond the free cap (3) until you renew. All data stays intact.
Is the Pro License a subscription?
Yes — it renews annually at €299. You’ll receive an invoice and new license key each year. You can cancel anytime.
How does Cloud Hosted provisioning work?
After payment, we create your tenant within 24 hours. You’ll receive an email with your login URL, username, and temporary password. Then bring your API key and start chatting.
Which AI models are supported?
DeepSeek, OpenAI (GPT-4o, GPT-4), Anthropic (Claude), Ollama (local models like Llama 3, Mistral), and any OpenAI-compatible API.
Can I cancel Cloud Hosted?
Absolutely — cancel anytime. Your subscription stops and your tenant is archived. No long-term commitment.
What’s the difference between Free and Pro?
The free version (MIT license) is limited to 3 tenants. Pro removes this cap entirely and includes priority support. All features are available in both.
Do I need technical knowledge?
For self-hosted: basic Docker knowledge helps. For cloud hosted: none — we manage everything. Both require you to obtain your own AI provider API key.
