What are Nuclei Templates?

Nuclei templates are the cornerstone of the Nuclei scanning engine. Nuclei templates enable precise and rapid scanning across various protocols like TCP, DNS, HTTP, and more. They are designed to send targeted requests based on specific vulnerability checks, ensuring low-to-zero false positives and efficient scanning over large networks.

​
YAML

Nuclei templates are based on the concepts of YAML based template files that define how the requests will be sent and processed. This allows easy extensibility capabilities to nuclei. The templates are written in YAML which specifies a simple human-readable format to quickly define the execution process.
