Sandbox Laravel Package
cosmira/sandbox
Cosmira Sandbox provides a lightweight, isolated environment for experimenting with Laravel and PHP code. Use it to safely test package behavior, reproduce issues, and validate changes without risking production data or configuration.

Frequently asked questions about Sandbox
- What is Cosmira Sandbox used for in Laravel applications?
- Cosmira Sandbox provides a controlled environment for running untrusted or experimental PHP code inside a Laravel application. It is aimed at evaluating snippets, testing user-provided logic, and prototyping safely without exposing the host application. Execution is isolated behind a simple API with clear error handling for restricted or failed code.
- How do I install cosmira/sandbox with Composer?
- Install the package with composer require cosmira/sandbox and confirm the resolved constraint matches the release you intend to run. Laravel packages typically register their service provider through package discovery, but check the repository README for any publishable configuration or post-install steps. Run the install in a non-production environment first so you can validate behavior before rollout.
- Which Laravel and PHP versions does cosmira/sandbox support?
- The package overview does not list explicit Laravel or PHP version constraints, so the authoritative source is the require section of the package composer.json and the tagged releases on Packagist. Check that constraint against your application's framework version before adding the dependency to a production project. If you maintain several Laravel versions, test the install in each rather than assuming compatibility.
- How do I configure limits for sandboxed code execution?
- Cosmira Sandbox exposes configurable limits so sandboxed runs stay within boundaries you define, which is central to its safer-execution model. Start from the package configuration file described in the README and tune the values to match your workload and payload sizes. Because the overview does not enumerate every limit key, confirm the available options against the source or documentation before relying on defaults.
- Is it safe to run untrusted PHP with Cosmira Sandbox in production?
- The package is designed to isolate execution and provide configurable limits for safer sandboxed runs, making it suitable for controlled evaluation of experimental or user-provided logic. Treat it as one layer of defense rather than a complete containment strategy: for genuinely hostile code you should also rely on process or container isolation, resource limits, and least-privilege credentials at the infrastructure level. Validate your configuration with representative payloads before enabling it on a production environment.
- How does Cosmira Sandbox handle errors from restricted or failing code?
- It provides clear error handling for restricted or failed code, so a run that violates a limit or hits a restriction should surface an error instead of silently continuing. Catch those errors at the call site and decide whether to log, retry, or reject the snippet. Exception classes are not enumerated in the overview, so inspect the package source before building error-handling logic around it.
- Can I use Cosmira Sandbox to reproduce a Laravel issue or test a package?
- Yes, the package blurb positions it for experimenting with Laravel and PHP code, testing package behavior, reproducing issues, and validating changes without risking production data or configuration. That makes it convenient for quick evaluation loops during debugging or dependency upgrades. Keep sandbox runs away from production databases, credentials, and other sensitive resources.
- How do I evaluate a PHP snippet with Cosmira Sandbox?
- The package exposes a simple API for quick evaluation and testing: you pass code into the sandbox call and receive the result or an error. Wrap the call in a try/catch so restricted or failed code is handled explicitly rather than bubbling up unexpectedly. Refer to the README for the exact method signature, supported input format, and return shape before writing integration code.
- Is cosmira/sandbox actively maintained and how should I handle upgrades?
- Check the repository release history and Packagist versions to judge maintenance activity before adopting the package, since the provided overview does not state a support policy. Pin a version constraint in composer.json and review the changelog between tags, especially when moving across minor releases. Upgrading in a staging environment first lets you confirm the API and configuration keys you depend on still behave as expected.
- What are the alternatives to Cosmira Sandbox for sandboxed PHP execution?
- Alternatives include running code in a separate process or container, tightening PHP settings such as disable_functions and open_basedir, or using dedicated sandboxing extensions and hosted execution services. Cosmira Sandbox targets developers who want a lightweight, Laravel-native wrapper with configurable limits and a simple API. Choose based on how hostile the incoming code is and how strict your isolation and compliance requirements are.
