`@remix-project/remix-analyzer` is a tool to perform static analysis on Solidity smart contracts to check security vulnerabilities and bad development practices. It works underneath Remix IDE plugin "SOLIDITY STATIC ANALYSIS" which is used to run analysis for a compiled contract according to selected modules. `@remix-project/remix-analyzer` is a tool to perform static analysis on Solidity smart contracts to check security vulnerabilities and bad development practices.

remix-debug wrap other remix-* libraries and can be used to debug Ethereum transactions. `@remix-project/remix-debug` is a tool to to debug Ethereum transactions on different Remix environments (VM, testnet etc.). It works underneath Remix IDE "DEBUGGER" plugin which is used to analyse step-to-step executioon of a transaction to debug it.
