Postgres Sandbox (postgres.new) spins up real PostgreSQL databases directly in your browser using PGlite. Write SQL and a fresh database is created automatically — no install, no server. It pairs that sandbox with AI assistance for generating SQL, plus support for CSV import, charts, ER diagrams and semantic search experiments.

A new PostgreSQL database is created automatically in your browser via PGlite — no server, no installation, no configuration.
An AI assistant helps generate and reason about SQL from natural-language prompts, lowering the barrier for schema and query work.
Load CSV data and start querying it directly, which makes the sandbox handy for quick analysis and data exploration.
Turn query results into charts and draw ER diagrams to visualise table relationships within the same workspace.
专项更强直接将团队与经过验证的人类参与者连接以进行偏好调整与研究，但缺乏托管的端到端标注管线。
结合自定义软件与专门的专家团队来处理复杂业务，但属于量身定制的服务。
结合强大的数据标注工具与自动化工作流程，但比人力托管服务更专注于软件工具。
免费 / 开源响应式 TypeScript 后端，集数据库、函数与 AI 网关于一体
提供先进的多模态数据策展与标注基础设施，但标注工作需要自备人力。
免费 / 开源Provides a flexible open-source annotation platform for self-hosting, but lacks Appen's managed enterprise human workforce services.

Tinybird is a data platform that pairs managed ClickHouse® with a hosted API, ingestion and MCP layer so engineering teams can build and ship real-time analytics products without operating database clusters themselves. It combines sub-second SQL querying, streaming and batch ingestion connectors, branching workflows and AI-agent tooling in one workflow.
