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.

Remix IDE is an IDE for Solidity dApp developers, powered by Remix. The Remix IDE repository is available here , and an online version is available at https://remix.ethereum.org.

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 .
