RAGFlow - Pros & Cons
Pros
- ✓Strong document-ingestion focus: supports complex unstructured formats as well as Word, slides, spreadsheets, text, images, scanned copies, structured data, and web pages.
- ✓Explainable chunking workflow with template-based chunking options and visualization of text chunks so humans can inspect or intervene before retrieval quality problems become answer quality problems.
- ✓Grounded answer design includes quick reference views and traceable citations, which is useful for legal, finance, compliance, and internal knowledge workflows where source evidence matters.
- ✓Hybrid retrieval stack combines vector search, BM25/full-text search, custom scoring, multiple recall, and fused reranking rather than relying only on embeddings.
- ✓Open-source Apache-2.0 project with substantial GitHub traction, public documentation, Docker-based deployment, APIs, and active release history.
- ✓Agent capabilities are built into the product direction, including visual workflows, tools, MCP integration, web search, chat channels, agent memory, and code executor support.
Cons
- ✗Self-hosting is infrastructure-heavy for casual users: the README lists minimum requirements of 4 CPU cores, 16 GB RAM, 50 GB disk, Docker, Docker Compose, and Python 3.13.
- ✗Prebuilt Docker images are documented as x86 only; ARM64 users must build compatible images themselves, and switching Infinity on Linux ARM64 is not officially supported.
- ✗The Docker image is now a slim edition that relies on external LLM and embedding services, so teams still need to configure and pay for model providers or run compatible model infrastructure.
- ✗The full stack has several moving parts, including document engine configuration, Docker environment files, backend service settings, and storage/search dependencies, which raises operational complexity.
- ✗Cloud lower tiers have tight dataset-storage limits, especially the Free tier at 0.1 GB and Starter at 5 GB, which may be too small for realistic enterprise document collections.
Cognee - Pros & Cons
Pros
- ✓Graph-native memory beats flat vector RAG for structured questions
- ✓Multiple backend choices — no forced JVM, no forced vendor DB
- ✓Provenance chain makes memory auditable for regulated deployments
- ✓MCP server slots into modern agent runtimes with zero SDK work
- ✓Apache 2.0 with a real managed cloud when self-hosting the graph is too much
Cons
- ✗LLM extraction on ingest adds real per-document token cost
- ✗Setup for the fully self-hosted path involves multiple databases
- ✗Graph quality depends on extraction prompts — needs tuning for domain vocabularies
- ✗Smaller ecosystem than pure vector RAG stacks
- ✗Cloud pricing starts to matter quickly at higher ingest volumes
