Compiler Explorer is a web‑based application that lets you write source code in many languages and instantly see the generated assembly or other compiler outputs. It runs in the browser and can also be self‑hosted via Docker for private use or integration into other tools.

Use cases

• view assembly output for C++ code instantly
• compare how different compilers optimize the same snippet
• experiment with compiler flags and see their effect in real time
• debug low‑level code by inspecting generated IR or AST
• benchmark compiler performance with quick‑bench feature

When to choose

• You need an interactive, browser‑based environment to explore compiler output without installing toolchains locally
• You want to compare multiple compilers and versions side‑by‑side
• You require visualizations like assembly, IR, control‑flow graphs for educational or debugging purposes

When to avoid

• You need offline compilation without any network or Docker dependencies
• Your workflow requires deep integration with IDEs beyond a web UI
• You need to compile large projects where the service’s resource limits are restrictive
