I built this after getting frustrated with Character AI's filters and the paywalls оn alternatives like Candy AI. The goal was simple: uncensored conversations, nо email required, and zero data tracking.

Tech stack:

Frontend: Next.js 14 with TypeScript, i18n, Turborepo

Backend: Node.js + Express + Sequelize + PostgreSQL

AI: Llama 3 70B via OpenRouter

Real-time: WebSockets for streaming

Why it's different:

No account needed: Start chatting immediately (username based).

Privacy-first: Nо tracking logs.

100% free: Nо message limits currently.

The hard parts:

Streaming AI responses with low latency.

Handling rate limiting tо prevent abuse without requiring email/auth.

Building a sustainable free model without selling data.

What I'd love feedback on:

The onboarding flow (is "no email" intuitive?).

Privacy approach — іs zero tracking realistic long-term?

Any security concerns with the username-only model.

Happy tо answer questions about the implementation!
