## HydraDB OSS

HydraDB OSS is an open-source graph database designed for the memory and context layers of AI agents. Rather than stitching together a vector database, a graph store, and a relational database, it puts entities, relationships, traces, and preferences into a single graph that lives on object storage. The result is a database whose storage cost scales like S3 while queries stay fast enough for interactive agents.

The architecture separates write, index, and read nodes: Cypher writes land in a write-ahead log, an indexer builds GraphBLAS-backed indexes, and readers merge the index with pending WAL entries for strong consistency. Tiered storage moves hot data from in-memory cache to NVMe to cold object storage on demand. Built-in retrieval combines graph traversal with vector, BM25, and reranking so a query like "what breaks if I change this function" can be answered in a single call.

HydraDB OSS ships under an open-source license, so teams can self-host on any S3-compatible store, import graphs from other databases, and use the supplied SDKs and an HTTP API. The same engine is offered as a managed cloud service for teams that would rather not operate the cluster themselves. Helpful extras include assisted ontology creation, entity resolution, and temporal versioning that tracks what changed and when.

**Pricing & Plans:** The open-source edition is free to self-host with community support. Managed cloud starts around $25/month minimum usage, a Scale tier around $300/month, and an Enterprise plan with custom (contact sales) pricing.

- **Object-storage-native engine:** Graph, WAL, value, and index data all live in S3-compatible storage with a hot/warm/cold tiering strategy, cutting infrastructure cost dramatically versus memory-resident graph databases.
- **Unified retrieval layer:** One query can traverse graph relationships and run vector, BM25, and reranked search together, so agents do not have to orchestrate four separate systems.
- **Temporal versioning and memory:** Every change is tracked, letting agents recall what happened, when, and in what sequence, which supports auditability and long-running agent workflows.
- **Neo4j-compatible interfaces:** OpenCypher over Bolt plus an HTTP API and SDKs make it approachable for teams already familiar with property graphs.
- **Assisted graph creation:** Ontology suggestions and entity resolution help teams build usable knowledge graphs without hand-designing every schema relationship.

**Strengths:** Free open-source edition with an active GitHub community; Storage costs scale with object storage rather than reserved database volumes; Combines graph, vector, and keyword retrieval in one system; Neo4j-compatible Cypher and Bolt reduce the learning curve

**Limitations:** Self-hosted deployment requires operating multiple node roles; Managed cloud has a monthly minimum spend; Newer project than established graph databases, so ecosystem maturity varies

## Trieve

Trieve is infrastructure for teams building search and retrieval-augmented generation. Rather than stitching together a vector database, an embedding pipeline, a ranking layer and a chat interface, Trieve provides them as one platform with an API surface. The emphasis is on hybrid retrieval that blends keyword matching with semantic search, so a system copes with both precise filters and fuzzy natural-language questions.

A substantial part of the value is in the operational details. Trieve manages how documents are chunked and embedded, then gives you tooling to inspect and improve relevance over time. Analytics expose how real queries behave, which lets you tune rankings instead of guessing. Conversational AI features turn that retrieval layer into assistants and knowledge bots grounded in your own content, which is the pattern most useful for support, documentation and e-commerce discovery.

Deployment flexibility is deliberate. Trieve can run as a managed service for teams that want to move fast, or be self-hosted from its open-source codebase when data locality or infrastructure control is required. Pricing is quoted based on usage and configuration, so organisations typically start with a conversation about their retrieval volumes and requirements.

**Pricing & Plans:** Contact for pricing; plans are quoted based on usage and configuration, with a self-hosted open-source option as well.

- **Hybrid search:** Combine keyword and vector search so results stay relevant for both exact queries and semantic intent.
- **Chunk management:** Manage documents, chunking and embeddings within the platform instead of building a pipeline from scratch.
- **Conversational RAG:** Add retrieval-augmented chat over your own content for assistants and knowledge bases.
- **Quality tuning and analytics:** Inspect search quality with analytics, then tune ranking and relevance based on real queries.
- **Developer API:** Access everything through APIs so search and chat can be embedded in your own product.
- **Managed or self-hosted:** Run Trieve as a hosted service or deploy the open-source stack on your own infrastructure.

**Strengths:** Combines hybrid search, RAG chat and analytics in one platform; Open-source and self-hostable for infrastructure control; API-first, so it embeds cleanly into existing products; Relevance tooling helps improve quality after launch

**Limitations:** Developer-focused; requires engineering effort to integrate; Self-hosting means you carry infrastructure and operations cost
