Compiler Explorer is an online tool and analysis platform used to translate source code into assembly in real time. It functions as a cross-compiler analysis tool, allowing users to examine how various compilers and versions translate the same source code into machine code to analyze optimizations and generation patterns.
The platform supports low-level language debugging and the comparison of assembly output across different compiler toolchains. It also provides a self-hosted environment option for users who need to run private deployments with custom binaries or operate within secure offline networks.
The system integrates a remote-execution backend that runs compiler binaries in sandboxed processes and a web-based frontend. It includes a network interface for querying compiler data and retrieving assembly output via an API.
