Every contribution makes a difference

We welcome contributions of any kind including pull requests, ideas, bug reports, testing, writing documentation, tutorials and blog posts. If you help with development, you have the opportunity to learn Symfony, PHPUnit, Vue.js and much more.

Since we are already pretty much feature-complete for our own needs, it is well possible that you won't find any open issues. Issues labeled help wanted / easy can be good (first) contributions otherwise.


Feel free to send an e-mail to if you have any questions, need commercial support or just want to say hello.

Pull Requests

Our step-by-step guide explains how to submit new features, bugfixes and documentation.

Feature Requests

You are welcome to add specific feature requests directly to our main GitHub issue tracker or the corresponding sub-project if no similar idea or todo already exists. Please don't use the issue tracker to ask general questions.

Reporting Bugs

Please use the GitHub issue tracker for symlex/input-validation or the corresponding sub-project to report clearly identified bugs and impediments to us. If you're not sure, start by asking via email. When reporting an issue, please provide the version in use and information about your environment like browser, operating system, installed memory, and processor type.


Please leave a star on GitHub if you like this project, it provides enough motivation to keep going. Thank you very much! <3
