Terms

SandboxMaster provides a local code laboratory. Run only code you understand and have permission to use. You retain ownership of your source code.

Execution environment

The first release supports snippets up to 65,536 characters, a 30-second worker execution limit and up to 100 saved sandboxes on each device per account. PHP and Python runtimes do not provide a full Android or production-server environment. External packages and networking are not supported in this version. TypeScript transpilation does not replace full project type checking.

Keep backups of important code. Local storage can be lost when uninstalling or clearing app data. Availability and future features may change; no future capability is guaranteed.

Third-party runtimes

Bundled components include Pyodide, TypeScript and PHP WebAssembly from WordPress Playground. Their licenses and corresponding source information are available in the app release documentation.
