Weaviate

Weaviate

Freemium

Open-source, cloud-native vector database that combines vector similarity search with structured filtering for scalable semantic search.

Key features

  • Vector + Structured Filtering: Stores both objects and vectors to allow combining semantic nearest-neighbor search with exact keyword and structured filters in the same query for precise, context-aware retrieval.
  • Retrieval‑Augmented Workflows & Reranking: Built-in support for RAG patterns and reranking pipelines so results can be retrieved by vector similarity, filtered, and then re-scored to improve LLM responses and reduce hallucination.
  • High‑Performance Nearest‑Neighbor Search: Core engine optimized for low-latency k-NN queries (e.g., 10-NN on millions of objects in milliseconds), enabling real-time semantic search at scale.
  • Multiple APIs & Client Libraries: Exposes GraphQL and REST APIs (plus gRPC in newer releases) and provides official client libraries across popular languages to simplify integration into applications.
  • Modular Vectorization & Extensibility: Supports pluggable vectorizers and modules so teams can use built-in models or integrate custom ML/embedding models for text, images, and multimodal data.
  • Cloud‑Native Scalability & Fault Tolerance: Designed to run as a distributed, cloud-native service with scalability and fault tolerance suitable for production deployments.
  • Embedded & Container Deployment Options: Offers Embedded deployment models and Docker-based setups for local or application-embedded instances, enabling flexible hosting options.
  • Single Query Pipeline: Allows combining vector search, filtering, and reranking in a single query call to simplify application logic and reduce round trips.
  • Stores objects and vectors together for combined vector similarity and structured filtering
  • APIs: GraphQL and REST (primary), gRPC available since v1.23 for lower latency
  • Client libraries for multiple languages (official and community-supported)
  • Retrieval-Augmented Generation (RAG) and reranking within query pipeline
  • Built-in vectorization using ML models with support for custom models
  • Cloud-native deployments via Docker and Kubernetes; managed cloud options available
  • Embedded Weaviate mode (runs inside application; experimental and not supported on Windows)
  • High-performance nearest-neighbor search (benchmarks: ms-level 10-NN on millions of objects)
  • Open-source BSD-3-Clause license with active GitHub ecosystem and examples

Best for

  • Retrieval‑Augmented Generation: Serve as the retrieval layer for LLM applications, returning relevant documents or passages to reduce hallucinations and supply context for prompts.
  • Semantic Search & QA: Implement natural-language search over large text or multimodal corpora (documents, web content, images) with relevance ranking and structured filtering.
  • Recommendation Engines: Use vector similarity on user/item embeddings combined with metadata filters to generate personalized recommendations at scale.
  • Chatbots & Conversational Agents: Power context-aware chat experiences by retrieving relevant context snippets, conversation history, and knowledge base entries for each query.
  • Image & Multimodal Search: Index and search images or mixed media using embeddings to enable visual search or cross-modal retrieval (e.g., image-to-text matching).
  • Content Classification & Tagging: Retrieve semantically similar examples to support automated labeling, classification, or moderation workflows.
  • Application‑Embedded Databases: Run Embedded Weaviate within an application or containerized deployment for local low-latency semantic search without a separate server.
  • Retrieval-Augmented Generation systems and RAG pipelines
  • Semantic text and image search over large corpora
  • Recommendation engines based on vector similarity and structured filters
  • Chatbots and question-answering layered with retrieval and LLMs
  • Content classification, tagging, and semantic analytics

WeKnora

Tencent

Free

Tencent's open-source LLM knowledge framework turning documents into a RAG-queryable, agent-reasoned, self-maintaining wiki.

Key features

  • RAG Quick Q&A: Semantic retrieval over ingested documents for everyday lookups, with editable retrieval chunks that support per-version diff, rollback and automatic reindexing.
  • ReAct Agent Orchestration: An autonomous agent that plans across retrieval, MCP tools, a per-tenant skill catalog, sandboxes and web search to resolve complex multi-step questions.
  • Wiki Mode: Agents distil raw uploads into a self-maintaining, interlinked markdown knowledge base with an interactive knowledge graph, in-browser editing, line-level diffs and one-click rollback.
  • Skill Sandbox Runtime: Session-persistent Docker, E2B and Cube sandbox backends with per-tenant network policy, skill installation from ClawHub, SkillHub, git or zip, snapshots and live progress.
  • Cross-Session Long-Term Memory: Profile, preference, fact, task and interest memory extracted automatically with user confirmation and searchable across sessions.
  • Multi-Source Ingestion: Auto-syncing knowledge from Feishu Wiki and Drive, GitLab, Tencent IMA, Notion, Yuque, DingTalk Docs and RSS, with 10+ document formats including PDF, Word, Excel, images and XMind.
  • Swappable Provider Stack: 20+ LLM providers including OpenAI, DeepSeek, Qwen, Zhipu, Hunyuan, Gemini, MiniMax, NVIDIA, LiteLLM and Ollama, with interchangeable vector databases and storage backends per workspace.
  • Enterprise Multi-Workspace RBAC: A four-tier role matrix with per-resource ownership, per-workspace audit logs, scoped API keys with a principal model, OIDC JWKS verification and Langfuse OTel tracing.

Best for

  • Internal Knowledge Base: Turning scattered company documents into a queryable wiki that agents keep current instead of a folder of stale files.
  • Data-Sovereign Deployment: Running a full RAG and agent stack on private cloud or local infrastructure where documents cannot leave the network.
  • IM-Channel Support Bot: Serving grounded answers from company documents directly inside WeCom, Feishu, Slack or Telegram.
  • Multi-Source Documentation Sync: Keeping a single searchable index over Notion, GitLab, Feishu and Yuque content that syncs automatically as sources change.
  • Retrieval Quality Tuning: Editing, diffing and reverting individual retrieval chunks in the UI to fix bad answers without rebuilding the whole index.
  • Agent Pipeline Observability: Using Langfuse tracing and the runtime task queue dashboard to see agent reasoning, token usage and worker pool behaviour in production.
  • Embedded Public Agents: Publishing a knowledge agent to an external website through embed widgets and scoped API keys.
