Overview
Magic Cloudlet is a .NET 10 backend with a React dashboard. It generates database CRUD endpoints, auth, role-based access and frontend files from natural-language prompts, in a language called Hyperlambda. Every endpoint in the modules folder can be exposed as an MCP tool through the mcp plugin, and it also includes OpenAPI import, a chatbot wizard and a sandbox endpoint for caller-supplied code.
Who it is for: Self-hosters wanting a prompt-driven backend with RBAC and MCP tool exposure
Its own README calls it an alternative to Cursor, Lovable, Replit.
Ranked among open-source alternatives to Cursor (#10 of 10), Lovable (#9 of 10), Bolt.new (#9 of 10) and Replit (#9 of 10).
Strengths
- Generates secured CRUD APIs over MySQL, PostgreSQL, SQL Server or MariaDB schemas
- Built-in MCP server turns each endpoint into a tool for Claude, Cursor or Codex
- Saved code runs immediately, with no build or deploy step
- MIT license; Docker Compose setup with ports 4444 (API) and 5555 (dashboard)
Weaknesses
- Apps are written in Hyperlambda, a niche language, so skills and code do not carry over
- Code generator is the author's proprietary LLM, not an open model
- Defaults to OpenAI; semantic retrieval still needs OpenAI embeddings even with Ollama
- Default login is root/root; the benchmark is single-machine and not independently replicated
What it needs
- C#, OpenAI, Ollama, HuggingFace
- Needs OpenAI API key (default), Docker Compose, SQLite
- README: alternative to Cursor, Lovable, Replit
