Why Nexus is Different
1. Security First Architecture
Unlike most AI assistants that expose your API keys in the frontend, Nexus uses a zero-trust security model. Your Groq API key is encrypted with AES-256 and stored securely in the vault. The widget uses a separate, domain-restricted Nexus key that only works for authorized origins.
2. True Freemium Model
Nexus offers a generous 1,000 free requests per month – no credit card required. Other AI assistants often have limited free tiers or require payment upfront.
3. Open Source & Self-Hostable
Nexus is completely open source under the MIT license. You can self-host the entire stack – widget and backend – on your own infrastructure. Full control, no vendor lock-in.
4. Context-Aware Answers
Nexus automatically scrapes your page content and provides answers grounded in your actual content – not generic AI hallucinations. This means more accurate and relevant responses for your users.
5. Developer-Friendly
With support for 15+ frameworks and a simple script tag integration, Nexus is built for developers. No complex setup – just copy, paste, and go.
