About Help4.Dev
Founded in 2024, Help4.Dev is an online portal offering free tools for programmers. Our mission is to support programming students, developers, analysts, and software testers with practical and accessible resources.

Who is Help4Dev for?
Help4Dev was built for developers, system analysts, QA testers, programming students, and any technology professional who needs fictitious data to validate systems during the development cycle. If you work with forms, API integrations, database testing, or user registration flows and need data that passes algorithmic validation, Help4Dev is the right tool for you.
Beyond seasoned professionals, Help4Dev is also great for students taking their first steps in programming who need to test their applications. With a clean and intuitive interface, anyone can generate or validate data in seconds — no sign-up, no installation required.
Our Mission
Help4Dev's mission is to democratize access to software development and testing tools. We believe that every developer, regardless of their experience or financial resources, should have access to quality tools to perform their work efficiently.
We develop tools that rigorously follow the official validation algorithms for Brazilian and international documents, ensuring that generated data is mathematically valid and accepted by systems that perform algorithmic verification.
