✨ Highlights

  • Open-source alternative to Perplexity AI emphasizing self-hosting and transparency
  • Uses SearxNG to keep results fresh without relying on proprietary crawled indexes
  • Local LLMs and Ollama/self-hosted API require significant deployment and configuration effort
  • Limited maintainers/contributors and current RC release mean stability is yet to be proven

🔧 Engineering

  • Combines SearxNG metasearch with vector similarity to deliver answers with cited sources
  • Supports multiple local/remote models (Ollama, Qwen, DeepSeek, Mistral, etc.)
  • Built-in focus modes and an API facilitate integration into applications or research workflows

⚠️ Risks

  • Running local models imposes high hardware, network and port-configuration requirements and fragility
  • Some features depend on third-party services (OpenAI, Groq, Anthropic, Gemini), introducing external dependency risk
  • Only 10 contributors and infrequent releases imply non-trivial long-term maintenance and security patching risk

👥 For who?

  • Developers and small teams preferring self-hosting and data sovereignty
  • Researchers and content reviewers who need explainable sources and academic search
  • Engineering teams with ops capabilities willing to manage local models and containerized deployments
