--- title: "Data & Retrieval" type: "category" slug: "data-retrieval" canonical_url: "https://www.graphcanon.com/categories/data-retrieval" tool_count: 396 --- # Data & Retrieval *GraphCanon updated Aug 22, 2026* Ingestion, chunking, parsing, scraping, and retrieval pipelines that feed context into LLMs (Unstructured, Firecrawl, document loaders). GraphCanon lists 396 published tools in Data & Retrieval. graphify leads adoption at 107,507 GitHub stars. Ingestion and chunking quality usually dominates RAG outcomes more than the vector store brand. Match parsers and loaders to your document types; skip heavy frameworks when a script plus embeddings API covers a small, static corpus. 396 tools in this category (showing the top 60 by stars). ## Featured comparisons - [MaxKB vs openagent](/compare/1panel-dev-maxkb-vs-haohao-end-openagent.md) - [goose vs openagent](/compare/aaif-goose-goose-vs-haohao-end-openagent.md) - [goose vs openagent](/compare/aaif-goose-goose-vs-the-open-agent-openagent.md) - [deeplake vs databend](/compare/activeloopai-deeplake-vs-databendlabs-databend.md) - [deeplake vs mempalace](/compare/activeloopai-deeplake-vs-mempalace-mempalace.md) - [deeplake vs milvus](/compare/activeloopai-deeplake-vs-milvus-io-milvus.md) - [deeplake vs qdrant](/compare/activeloopai-deeplake-vs-qdrant-qdrant.md) - [activepieces vs openagent](/compare/activepieces-activepieces-vs-haohao-end-openagent.md) ## Stacks - [The RAG stack](/stacks/rag-pipeline.md) ## Tools - [graphify](/tools/graphify-labs-graphify.md) - Turn any code or documentation into a queryable knowledge graph (★ 107,507) [Very active] - [awesome-llm-apps](/tools/shubhamsaboo-awesome-llm-apps.md) - Over 100 runnable AI Agent and RAG apps to clone, tweak, and deploy.

GraphCanon ranks Data & Retrieval tools by GitHub adoption and freshness. graphify is the current leader (107,507 stars). See the full list on this page - sorted by stars, with [maintenance labels](/glossary/trust-and-signals/maintenance-label) and graph relationships. ### How does GraphCanon rank Data & Retrieval tools? We sort by GitHub stars and push recency on category pages, not paid placement. Alternatives and compare pages use [typed graph edges](/glossary/knowledge-graph/typed-edge) (alternative, successor, integrates_with) plus shared categories - constraint-first, not marketing votes. ### How many tools are in Data & Retrieval? 396 published tools are tagged with Data & Retrieval in the GraphCanon knowledge graph. ### What are popular Data & Retrieval comparisons? Head-to-head compare pages in this category include MaxKB vs openagent, goose vs openagent, goose vs openagent. Each comparison uses live GitHub stats and optional [trust signals](/glossary/trust-and-signals/trust-signal) - see the comparisons block on this page. ### Which stacks use Data & Retrieval? Curated workflow pages that include Data & Retrieval: [The RAG stack](/stacks/rag-pipeline). Each stack step includes when-not-to-use guidance. ### Where are graph-backed alternatives hubs for Data & Retrieval? High-intent OSS-vs-OSS alternatives pages include [LangChain alternatives](/tools/langchain-ai-langchain/alternatives), [LlamaIndex alternatives](/tools/run-llama-llama-index/alternatives), [Qdrant alternatives](/tools/qdrant-qdrant/alternatives), [FinRobot alternatives](/tools/ai4finance-foundation-finrobot/alternatives), [free-llm-api-resources alternatives](/tools/cheahjs-free-llm-api-resources/alternatives), [caveman alternatives](/tools/juliusbrussee-caveman/alternatives), [rtk alternatives](/tools/rtk-ai-rtk/alternatives), [unsloth alternatives](/tools/unslothai-unsloth/alternatives), [ollama alternatives](/tools/ollama-ollama/alternatives). Each hub ranks typed graph neighbors and constraint tags - not popularity votes. ### Is there a machine-readable Data & Retrieval list? Yes. Append `.md` to this URL or fetch [`/md/categories/data-retrieval`](/md/categories/data-retrieval) for a markdown twin. The JSON API exposes the same corpus at [`/api/graphcanon/categories/data-retrieval`](/api/graphcanon/categories/data-retrieval). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/categories/data-retrieval`](/api/graphcanon/categories/data-retrieval) - 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/_
