MoonDB

MoonDB is a hosted, AI-friendly Database-as-a-Service (DBaaS) and backend-as-a-service (BaaS) built for AI coding agents and vibe-coding tools such as Cursor, Claude Code, Lovable, Bolt, and v0. Positioned as an alternative to Firebase and Supabase, it lets a developer or an agent stand up a working backend in three API calls: create a project, PUT a declarative JSON schema, then call the auto-generated REST API. The schema is the source of truth. It describes tables, columns, and relationships, and MoonDB handles the database and endpoints.

From that schema, MoonDB generates a REST API with filtering (field=op.value syntax), sorting, pagination, field selection, includes (joins), and bulk insert, plus built-in end-user authentication via JWT and file storage. Schemas use short-form column types, references with UUID text IDs, enums, and timestamps on by default, with per-table access rules for public, authenticated, owner, and admin. A Model Context Protocol (MCP) server lets agents provision and query a backend directly from their tools, and an optional model endpoint declared in the schema exposes Cloudflare Workers AI text models and image generation over REST.

The service runs at the edge on Cloudflare Workers, with D1 (SQLite) for data, R2 for files, and KV for configuration. It is agent-friendly but agent-optional, so people can use it directly. Because it is SQLite/D1-based, it has a single writer per database and a roughly 10 GB cap, and it is not a Postgres replacement or a vector database. A free plan includes one project, 500 MB storage, and about 500K reads plus 10K writes per month; paid plans are Half Moon ($9/mo), Full Moon ($29/mo), and Eclipse ($99/mo).
