✨ 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
