An opinionated prototyping platform for data-centric applications

• Written in Go and vanilla JS
  • Fast (site is available in about 100ms)
  • Small (Backend code is below 2k lines of code)
  • Simple to deploy (one self-contained native binary smaller than 20MB)
• Instantly create simple CRUD Applications from a JSON data model
• Generic persistence layer based on MongoDB
• Passwordless authentication using Sign in with Ethereum
  • (no, this is not a Web3 project..)
• Supports relationships between entries
• Automatic JSON API for all the data
• Hackable: small, easy to read codebase
• Search the whole database from a single input field
• Includes CSRF protection for all HTTP requests
• Very basic rights management
  • Public
  • Accessible by all users
  • Accessible only the logged-in user

Out of Scope

• No SSL / TLS (use a reverse proxy)
• No business logic (implemented as plugins)
• No special Field Types (implemented as plugins)
• No handling of binary data (binaries should be stored elsewhere and crude should only handle links)
• No tenant or project prefixes (use sub-domains and just host another instance)
• No simplified queries (client-side)
• No better UI/UX (client..)
• No complicated access rights management (only the basics are provided)
