There are a variety of OBD (On-Board Diagnostics) tools available that can be used to diagnose and repair vehicles, similar to VCDS. Some of the most common types of OBD tools include:

1. Code Readers: These are similar to OBD2 scanners, but they typically have fewer features and are less expensive. They are often used by car owners who want to check for DTCs and diagnose basic issues with their vehicles.
2. Advanced OBD2 Scanners: These are more advanced diagnostic tools that can read and clear DTCs, as well as perform advanced functions such as live data streaming and freeze frame analysis. They are commonly used by professional mechanics and technicians.
3. OEM Specific Tools: These are diagnostic tools that are specific to a certain make and model of vehicle, like the VCDS. They can be used to access advanced diagnostic functions and perform specialized repairs that may not be possible with more general-purpose OBD tools.
4. Multi brand OBD Scanner: They are also specific to certain makes and models. In combination with OEM specific tools they are the best choice for workshops which handle different car brands.

When deciding which OBD tool to use, it's important to consider your own level of experience and the types of repairs you will be performing. If you're a beginner, a basic OBD2 scanner or code reader may be sufficient for your needs. If you're more experienced or plan to perform more advanced repairs, an advanced OBD2 scanner or OEM-specific tool like VCDS may be more appropriate.

It's also important to note that some vehicles may have different OBD systems and protocols, so it's important to make sure the tool you choose is compatible with the make and model of your vehicle.

VCDS is the best diagnostic tool for Audi, Seat, Skoda and Volkswagen while a multi brand OBD scanner enables to do service and repair on multiple car brands.
