Why it's good
- Hosts Laravel or PHP apps with MySQL databases on eligible tiers
- Builds and deploys Solidity contracts to the Sepolia testnet
- Connects with Claude, Cursor, and MCP tools
- Supports browser testing of Chrome extensions and Flutter previews
- Backend, database, storage, and deployment limits depend on tier
Cloudpen provides a browser-based workspace for building and deploying applications. Depending on the license tier, it supports frontend deployments, persistent Laravel or PHP backends, and hosted MySQL databases with phpMyAdmin. Developers can also compile Solidity contracts with Hardhat and deploy to the Sepolia testnet. MCP connections let tools such as Claude Desktop, Claude Code, and Cursor access project files, git history, and deployment status.
Tier limits vary for storage, frontend and backend deployments, databases, Web3 deploys, and Flutter previews; some features are not included on every tier. Check the tier details against your project requirements. The deal provides lifetime access, with a stated redemption window and refund period; it is an early-stage product.
