Vane
Vane is a privacy-focused AI answering engine that runs locally on your own hardware, combining web search with support for local and cloud LLMs (Ollama, OpenAI, Claude, Groq). It delivers cited answers while keeping searches private and supports multiple content sources including web, academic papers, images, and uploaded documents.

What Vane is
TypeScript-based RAG application that integrates SearxNG for privacy-preserving web search, supports multi-provider LLM backends (local via Ollama, cloud via OpenAI/Anthropic/Groq), and implements document ingestion for file-based queries. Architecture documented; deployment via Docker or Node.js runtime.

Best use cases
Implementation considerations
- SearxNG is a hard dependency with specific config (JSON format enabled, Wolfram Alpha engine active). Plan for separate SearxNG host or accept bundled container overhead.
- Multi-provider LLM setup requires API key management (OpenAI, Anthropic, Groq, Ollama URLs). Design secure credential storage and rotation strategy early.
- Local Ollama deployment on Linux requires network exposure (0.0.0.0:11434) and firewall configuration; Windows/Mac use host.docker.internal bridge. Network topology varies by OS.
- Document upload feature implies file storage and processing logic. Evaluate file type support (PDF, text, images noted), size limits, and indexing performance impact.
- Search mode switching (Speed/Balanced/Quality) implies different LLM inference paths. Benchmark latency and token costs per mode before production rollout.
When to avoid it — and what to weigh
- Managed Search Appliance Required — Vane requires operational overhead (Docker, SearxNG instance, LLM provider setup). Not suitable if you need zero-touch hosted solution or lack infrastructure capacity.
- Closed Data Environment (No Internet Search) — Core value is web search integration. If you require fully air-gapped QA on internal documents only, consider dedicated RAG frameworks (LangChain, Llamaindex) instead.
- Scale-First Deployments — Limited production evidence. 329 open issues and ~2 years maturity suggest operational gotchas not yet surfaced at enterprise scale. Evaluate load-testing, HA, and monitoring requirements first.
- Compliance-Heavy Audit Trails — README does not describe audit logging, data retention policies, or compliance features. Requires deep code review before deploying in regulated industries (healthcare, finance).
License & commercial use
MIT License. Permissive OSI license allowing commercial use, modification, and distribution with no warranty and no liability. Attribution appreciated but not legally required.
MIT permits commercial deployment and resale without royalty. However: (1) verify all dependencies (SearxNG, Ollama, LLM provider SDKs) for compatible licensing; (2) external APIs (OpenAI, Anthropic, Groq, Tavily, Exa) have separate commercial terms; (3) no indemnification or SLA provided. Suitable for internal use or commercial products; recommend legal review of dependency chain.

Self-hosted model reduces data exposure vs. SaaS search engines. However: SearxNG and LLM provider connectivity must be secured (TLS, API key rotation). No encryption-at-rest or in-transit details in README. File upload feature requires input validation and malware scanning. Search history stored locally; no data retention or deletion policy stated. API keys stored in settings UI with no mention of encryption. Code audit recommended before handling sensitive queries.
Alternatives to consider
Perplexica
Similar privacy-focused answering engine architecture. May offer comparable features; evaluate feature parity and maintenance cadence.
LangChain / LlamaIndex RAG frameworks
Lower-level abstractions for custom RAG pipelines. Better fit if you need fine-grained control, air-gapped setup, or no web search component.
Managed SaaS (Perplexity API, You.com API)
Eliminates infrastructure burden if privacy and self-hosting are not requirements. Simpler deployment for teams lacking DevOps capacity.
