One query language, every data model

Documents, graphs, vectors, full-text, and time-travel — all through standard SQL via any PostgreSQL client.

SELECT * FROM 'default'
WHERE node_type = 'Article'
  AND properties->>'status'::String = 'published'
ORDER BY created_at DESC;

Everything you need in one database

A multi-model database that combines document storage, graph queries, search, and version control in a single system.

Git-like Versioning

Branches, tags, and commits for your data. Draft and commit workflows, merge operations, revision history, and time-travel queries.

CREATE BRANCH feature/new-content FROM main;

Schema-Driven Development

Define NodeTypes in YAML with typed properties, validation rules, inheritance, and constraints. Deploy schemas as part of your codebase.

PostgreSQL-Compatible SQL

Connect with psql or any PostgreSQL client. Query with JSON operators, hierarchical functions, and standard SQL.

Graph Queries

Model relationships with bidirectional edges. Traverse graphs with SQL/PGQ and the NEIGHBORS() function.

Full-Text Search

Tantivy-powered search with multi-language stemming, fuzzy matching, wildcards, and relevance scoring. Indexes update with your data automatically.

SELECT * FROM SEARCH('main', 'content:database AND type:article')

Vector Search

Store embeddings and run KNN similarity queries. Build semantic search, RAG pipelines, and AI agent memory without external vector stores.

RAP Packages

Package schemas, content, and functions into Raisin Archive Packages. Distribute and install reusable content modules.

Serverless Functions

Run JavaScript, Starlark, or SQL functions inside the database. Triggers, computed fields, and custom API endpoints.

DCAD: Schema-Driven Apps

Your schema defines your app. Archetypes map data to UX patterns — switch the archetype, change the entire interface without touching data.

Authentication & RBAC

Pluggable auth strategies, workspace-scoped roles, row-level security. Content-centric permissions that replicate across clusters.

ACID Transactions

Atomic commits across multiple operations. Begin, commit, or rollback — strong consistency across all data models in a single transaction.

Real-Time Events

Subscribe to node changes via WebSocket or SSE. Filter by workspace, node type, or path. Automatic reconnection and deduplication built in.

Built for Modern Applications

Content Management Systems

Manage articles, pages, and media with branching workflows and editorial review. Schema-driven content modeling with full revision history. Multi-tenant by design.

SaaS Platforms

Tenant isolation, workspace organization, and version-controlled data out of the box. REST API, WebSocket events, and PostgreSQL wire protocol for flexible integration.

AI Agent Memory & RAG

Give AI agents branching memory — each workflow gets its own branch to reason and iterate without corrupting shared state. Vector search for RAG, serverless functions for tool use, and full revision history so agents never lose context.

Schema-Driven Applications (DCAD)

Let your schema drive the UI. Archetypes define how data is presented — change the archetype, transform the interface. Build dynamic, data-centric apps without rewriting frontend code.

Use your existing tools

RaisinDB speaks PostgreSQL wire protocol. Connect with any standard library — no proprietary SDK required.

import pg from 'pg';
const pool = new pg.Pool({
  connectionString: 'postgresql://admin:admin@localhost:5432/myrepo'
});

// Standard PostgreSQL queries — just works
const { rows } = await pool.query(`
  SELECT path, properties->>'title'::String AS title
  FROM 'content'
  WHERE node_type = 'news:Article'
    AND properties->>'status'::String = 'published'
  ORDER BY created_at DESC LIMIT 10
`);

// Row-level security via user context
await client.query('SET app.user = $1', [accessToken]);
const results = await client.query(sql);
await client.query('RESET app.user');
