20 terms

Database3
Chroma

Chroma / ChromaDB / クロマ

A simple open-source vector database usable from Python and JavaScript. It supports in-memory, persistent, and HTTP server modes, making it the go-to tool for RAG prototyping and local LLM development.
Database3
Cloudflare R2

R2 (Cloudflare) / Cloudflare R2 / クラウドフレアR2

Cloudflare's S3-compatible object storage. Its defining feature is zero egress fees, enabling low-cost, low-latency file delivery from Cloudflare Workers and Pages without outbound transfer charges.
Database2
Convex

Convex / コンベックス

A TypeScript-native reactive backend platform that bundles a database, serverless functions, real-time subscriptions, and file storage in one service. Its reactive queries from the frontend are a defining feature.
Database3
Drizzle ORM

Drizzle ORM / Drizzle / ドリズルORM

A lightweight, type-safe ORM for TypeScript/JavaScript with a SQL-like query builder and schema-first design. It supports PostgreSQL, MySQL, SQLite, and Turso and is guaranteed to run in edge runtimes.
Database3
Edge Storage

Edge Storage / エッジストレージ / Vercel Blob

A category of storage services that place data near edge locations for low-latency file access. Vercel Blob, Cloudflare R2, and Fastly Object Storage are key examples, often used alongside CDN delivery.
Database2
libSQL

libSQL / リブSQL

An open-source SQLite fork led by Turso that removes SQLite's limitations around WAL, HTTP connections, and replication. It powers Turso's edge DB with added replication, encryption, and remote connection support.
Database3
MongoDB

MongoDB / モンゴDB

A document-oriented NoSQL database that stores data in BSON (JSON-like) format. Schema flexibility and easy horizontal scaling are its hallmarks, complemented by MongoDB Atlas as a fully managed cloud service.
Database3
MySQL

MySQL / マイSQL

One of the world's most widely used open-source RDBMSs. It became the default for WordPress and e-commerce platforms, and PlanetScale adopted it as the foundation for its distributed scaling service.
Database3
Neon

Neon / Neon DB / ニオン

A serverless PostgreSQL-compatible database service that separates storage from compute for auto-scaling and near-zero cold starts. Its official Vercel integration makes it a popular edge development database.
Database3
Pinecone

Pinecone / パインコーン

A fully managed vector database providing fast approximate nearest neighbor (ANN) search for high-dimensional vectors. Widely adopted as the backbone of RAG systems and semantic search with automatic scaling and index management.
Database2
PlanetScale

PlanetScale / プラネットスケール

A MySQL-compatible serverless database service based on Vitess. Key features include Git-like database branching for safe migrations, schema revert, and horizontal sharding for large-scale deployments.
Database3
PostgreSQL

PostgreSQL / Postgres / ポストグレSQL

A highly extensible open-source RDBMS with ACID compliance, JSONB support, full-text search, and the pgvector extension for AI/RAG workloads. The go-to choice for SaaS and enterprise systems alike.
Database3
Prisma

Prisma / Prisma ORM / プリズマ

A next-generation ORM for Node.js and TypeScript with a dedicated schema language (.prisma) and a type-safe Prisma Client. It broadly supports PostgreSQL, MySQL, SQLite, and MongoDB, with strong enterprise adoption.
Database3
Qdrant

Qdrant / クァドラント

A high-performance open-source vector database written in Rust. It features HNSW indexing, payload filtering, and quantization-based fast ANN search, available self-hosted or as Qdrant Cloud.
Database3
Redis

Redis / レディス

An in-memory key-value store widely used for session management, caching, pub/sub messaging, and rate limiting. The Redis Stack extension adds full-text search and vector similarity search.
Database3
S3-Compatible Storage

S3互換ストレージ / Object Storage / オブジェクトストレージ

The collective term for object storage services that implement the Amazon S3 API. Examples include Cloudflare R2, Backblaze B2, and MinIO. The shared API enables vendor-agnostic code using the same AWS S3 SDKs.
Database3
SQLite

SQLite / SQLite3 / エスキューライト

A serverless embedded RDBMS that stores data in a single file with zero setup. It underpins mobile apps, desktop apps, and is the base technology for Turso's edge-deployable libSQL fork.
Database3
Supabase

Supabase / スーパーベース

An open-source Backend-as-a-Service built on PostgreSQL. It bundles authentication, real-time subscriptions, storage, and Edge Functions, and has grown rapidly as a Firebase alternative.
Database3
Turso

Turso (libSQL) / ターソ

An edge-friendly database built on libSQL — a fork of SQLite — with multi-region replication, multi-tenancy, and very low operating cost, well-suited for direct connections from edge functions.
Database3
Weaviate

Weaviate / ウィービエイト

An open-source vector database with a native GraphQL API. It features an object-oriented data model and built-in hybrid search combining vectors and keywords, available self-hosted or via Weaviate Cloud.
