trieve

Trieve is an open-source, self-hosted platform built in Rust that provides search, recommendations, RAG, and analytics through a unified API. It integrates vector databases (Qdrant), embedding models, and LLMs to deliver hybrid search with semantic and sparse-vector capabilities.

What trieve is

Rust-based backend (Actix-web) with PostgreSQL storage, Qdrant vector integration, typo-tolerant neural search via SPLADE, hybrid search with cross-encoder re-ranking, and RAG orchestration via OpenRouter. Supports self-hosting on Kubernetes, AWS, GCP, or Docker Compose.

Quickstart

Get the trieve source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/devflowinc/trieve.git2cd trieve3# follow the project's README for install & configuration

Best use cases

Enterprise RAG Pipelines

Self-hosted RAG with custom LLMs, bring-your-own models, and topic-based memory management for sensitive document retrieval and Q&A at scale.

E-commerce & Content Discovery

Hybrid search with recency biasing, merchandizing tuning (clicks, add-to-carts), and recommendation APIs for personalized content or product discovery.

Knowledge Base & Internal Search

Semantic + full-text search with filtering, grouping, and sub-sentence highlighting for internal documentation, wikis, or technical knowledge systems.

Implementation considerations

Requires external API keys (OpenAI, Groq, or custom LLM) and embedding model setup; test embeddings and re-ranking model performance against your domain before production.
PostgreSQL + Qdrant + optional GPU embedding server(s) must be provisioned, monitored, and backed up; complexity increases if multi-region or high-availability is needed.
SDKs available (TypeScript, Python) but integration depth depends on your query/indexing patterns; prototyping filtering, grouping, and re-ranking logic early is critical.
Self-hosting requires Docker Compose or Kubernetes expertise; AWS, GCP, and Helm charts provided but customization for compliance or performance tuning may need support.
Bring-your-own-models path requires API standardization; ensure embeddings, re-rankers, and LLMs match Trieve's expected input/output shapes.

When to avoid it — and what to weigh

Fully Managed SaaS-Only Requirement — If you need zero infrastructure management, managed backup, or SLA-backed uptime, self-hosting burden may not fit. Trieve offers managed cloud (1k chunks free) but emphasis is on self-hosting flexibility.
Simple Full-Text Search Only — If your use case requires only traditional keyword search without semantic or vector capabilities, the operational complexity of Trieve and its dependencies (Qdrant, embedding servers) is unnecessary overhead.
Extreme Low-Latency Constraints — Multi-stage retrieval (dense + sparse + re-ranking) adds latency; if p99 must be <10ms, simpler single-stage search systems may be more suitable.
Budget Constraint on Infrastructure — Self-hosting requires PostgreSQL, Qdrant, embedding servers (GPU or CPU), and Trieve application servers; total resource footprint is substantial for small teams or MVPs.

License & commercial use

MIT License (OSI-approved, permissive). Allows commercial use, modification, and distribution with minimal restrictions (attribution recommended, no warranty).

MIT is a permissive OSI license; commercial use, proprietary deployment, and SaaS offerings are legally permitted. No GPL-style copyleft obligations. However, review dependencies (Actix, Diesel, SolidJS, etc.) for their own license compatibility, especially if bundling closed-source components. Professional services and support offerings mentioned but not detailed in repo; consult maintainers for commercial SLA terms.

Security considerations

Self-hosted model gives you control over data residency and access. No explicit security audit, penetration test, or CVE disclosure policy mentioned. PostgreSQL and Qdrant must be secured separately (network isolation, auth, encryption at rest/transit). API key management (LLM_API_KEY, OPENAI_API_KEY) requires careful .env handling. No native data encryption at rest mentioned; compliance (SOC2, HIPAA, GDPR) not explicitly documented—requires review before regulated workloads.

Alternatives to consider

Pinecone or Weaviate (Cloud)

Fully managed vector databases with simpler APIs; eliminate self-hosting but reduce control and increase per-query cost. No RAG orchestration built-in.

LangChain + Self-Hosted LLM + Vector DB

Framework-based approach with more flexibility and community integrations but requires more glue code and ops overhead than Trieve's unified API.

Elasticsearch or Solr

Mature full-text search with BM25 ranking and less operational complexity. Lack native vector search and RAG; less suitable for semantic retrieval.

trieve FAQ

Can I use Trieve for production without managed hosting?

Yes, full self-hosting supported on Docker Compose, Kubernetes, AWS, GCP, and on-prem. You own infrastructure, data, and compliance responsibility.

What embedding and LLM models are supported?

OpenAI, Jina, and your own via bring-your-own-model API. LLMs accessed via OpenRouter (supports many providers) or custom endpoints. Not all models tested; verify performance for your domain.

How does hybrid search improve results?

Combines dense semantic vectors (understanding meaning) with sparse neural search (typo-tolerant keyword matching) and re-ranks with cross-encoders; typically higher relevance than either alone.

What is the minimum hardware for small-scale deployments?

Not explicitly specified. Likely: 2–4 CPU cores, 4–8 GB RAM for API, plus dedicated resources for PostgreSQL and Qdrant. GPU optional for embeddings (accelerates indexing).
