Anvil

Anvil is an Intel-only application from 2017 with no native Apple Silicon build. The latest version (1.1.8) was compiled for x86_64 architecture and has not been updated since its original release—the app is effectively abandoned. It will continue to run under Rosetta 2 today, but Apple is removing Rosetta 2 in macOS 28 (September 2028), at which point this app will stop launching entirely. You have roughly two and a half years to migrate your local development workflow to a modern, actively maintained alternative. For a simple local HTTP server, consider using built-in tools like Python's built-in http.server module (python3 -m http.server), Node.js's http-server package, or a more feature-rich option like Live Server for VS Code, which all run natively on Apple Silicon and are under active development. If you rely heavily on Anvil's specific workflow, check whether a modern web framework or IDE with equivalent local-server capabilities would be a better long-term fit for your development process.
