Remix is a suite of tools that helps smart contract development, compilation, testing & deployment. These tools also works as a core of native plugins of Remix IDE.
For more, check out the Remix IDE documentation.
Remix is built out of several different modules. Here is the brief description.
remix-analyzer: Perform static analysis on Solidity smart contracts to check security vulnerabilities and bad development practices
remix-astwalker: Parse solidity AST (Abstract Syntax Tree)
remix-debug: Debug Ethereum transactions. It provides several controls that allow stepping over the trace and seeing the current state of a selected step.
remix-solidity: Load a Solidity compiler from provided URL and compile the contract using loaded compiler and return the compilation details
remix-lib: Common place for libraries being used across multiple modules
remix-tests: Unit test Solidity smart contracts. It works as a plugin & as CLI both
remix-url-resolver: Provide helpers for resolving the content from external URL ( including github, swarm, ipfs etc.).
remixd: Allow accessing local filesystem from Remix IDE by running a daemon
Each module generally has their own npm package and test suite, as well as basic documentation in their respective
READMEs. Usage of modules as plugin is well documented here.
