It provides enterprise knowledge management ## Choose when ### Choose deep-research if… - deep-research is primarily TypeScript; deep-searcher is Python. - License: deep-research is MIT, deep-searcher is Apache-2.0. - Requirements: Min 2 GB RAM; Requires Docker; Requires Node.js environment setup.; Needs specific API keys for third-party web search (Firecrawl) and language model services (OpenAI).. - Similar to 'deep-research', 'deep-searcher' aims at providing a tool for conducting private data reasoning and searching but is an alternative approach. - Tags unique to deep-research: research, ai, o3-mini, gpt. - You require a detailed and comprehensive report on a specific topic where traditional manual or less refined automated tools are too basic. ### Choose deep-searcher if… - deep-searcher is primarily Python; deep-research is TypeScript. - License: deep-searcher is Apache-2.0, deep-research is MIT. - Similar to 'deep-research', 'deep-searcher' aims at providing a tool for conducting private data reasoning and searching but is an alternative approach. - Tags unique to deep-searcher: llm, openai, claude, agentic-rag. - Also covers Vector Databases. - - **When you need a flexible embedding option**: DeepSearcher supports multiple embedding models like Milvus for optimal selection. ## When NOT to use deep-research - If your project requires proprietary or classified data analysis because Deep Research relies on public web scraping and search engines, which limits access to non-public content. - You are looking for a tool that operates solely offline; since the tool needs internet access to perform its tasks through API calls to services like Firecrawl and OpenAI. ## When NOT to use deep-searcher - - **If you require real-time web content integration only**: DeepSearcher primarily focuses on local/private data. Online content integration is possible but not its core functionality. - - **When strict API dependency avoidance is needed**: DeepSearcher often relies on specific APIs (e.g., OpenAI) for LLM services, which might be a constraint in environments strictly avoiding third-党 ## Common questions ### What is the difference between deep-research and deep-searcher? deep-research: An AI-powered research assistant that performs iterative, deep research on any topic. deep-searcher: Open Source Deep Research Alternative to Reason and Search on Private Data. See the comparison table for live GitHub stats and shared categories. ### When should I choose deep-research over deep-searcher?

Stars measure visibility, not whether either tool fits your constraints. ### Are deep-research and deep-searcher open source? Yes - both are open-source projects on GitHub (deep-research: MIT, deep-searcher: Apache-2.0). ### Where can I find alternatives to deep-research or deep-searcher? GraphCanon lists graph-backed alternatives at /tools/dzhng-deep-research/alternatives and /tools/zilliztech-deep-searcher/alternatives (/tools/dzhng-deep-research/alternatives.md, /tools/zilliztech-deep-searcher/alternatives.md), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at /compare/dzhng-deep-research-vs-zilliztech-deep-searcher.md mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, deep-research or deep-searcher? deep-research: Steady. deep-searcher: Slowing. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for deep-research and deep-searcher? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: deep-research: /tools/dzhng-deep-research/trust; deep-searcher: /tools/zilliztech-deep-searcher/trust. --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=dzhng-deep-research`](/api/graphcanon/graph?tool=dzhng-deep-research) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
