SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
evm.storage recently can now show storage layouts and track storage of unverified Solidity contracts (it works for simple Vyper contracts, too, but is not optimized for Vyper atm). We also opensourced our storage layout analyzer, which makes it possible -- The tool symbolically executes a contract’s bytecode to infer its storage layout. At times, it produces layouts that are even more accurate than those generated by solc with source code!
p.s We are the same team behind evm.codes
