Show HN: Nully – FOSS AI chat without the bloat

Nully is a minimal, open-source AI chat interface written in Go and vanilla HTML/CSS/JS. It sends messages via OpenRouter, stores chats locally, and offers basic features like attachments and web search without accounts, subscriptions, or bloat. The creator built it for personal use but released it as a lightweight, self-hostable alternative to feature-heavy AI services.

Background

- OpenRouter is a service that provides a unified API to dozens of AI models (OpenAI, Anthropic, Google, Meta, Mistral, etc.), letting users pay per-token without needing separate accounts for each provider. It's become popular among developers who want to switch models easily. - "Self-hostable" and "FOSS" (free and open-source software) mean anyone can download Nully's source code and run it on their own server, rather than depending on a company's hosted service. This appeals to users who want control over their data. - The critique here targets the bloat of mainstream AI chat interfaces: ChatGPT and Claude have added features like memory (saving preferences across conversations), agentic mode (letting the AI take actions on your behalf), deep research (multi-step web searching), and image generation. Some users just want a text-in/text-out interface without heavy UI or hidden data collection. - Go is a compiled language known for producing small, fast binaries — relevant to the performance graphs the creator mentions.
