Get Started
1. Nuclei CLI
Install Nuclei on your machine. Get started by following the installation guide here. Additionally, We provide a free cloud tier and comes with a generous monthly free limits:
- Store and visualize your vulnerability findings
- Write and manage your nuclei templates
- Access latest nuclei templates
- Discover and store your targets
[!Important]
This project is in active development. Expect breaking changes with releases. Review the release changelog before updating. This project is primarily built to be used as a standalone CLI tool. Running nuclei as a service may pose security risks. It's recommended to use with caution and additional security measures.

Single target scan
To perform a quick scan on web-application:
nuclei -target https://example.com
Scanning multiple targets
Nuclei can handle bulk scanning by providing a list of targets. You can use a file containing multiple URLs.
nuclei -list urls.txt
Network scan
This will scan the entire subnet for network-related issues, such as open ports or misconfigured services.
nuclei -target 192.168.1.0/24
Scanning with your custom template
To write and use your own template, create a .yaml file with specific rules, then use it as follows.
nuclei -u https://example.com -t /path/to/your-template.yaml
Connect Nuclei to ProjectDiscovery
You can run the scans on your machine and upload the results to the cloud platform for further analysis and remediation.
nuclei -target https://example.com -dashboard
[!NOTE] This feature is absolutely free and does not require any subscription. For a detailed guide, refer to the
documentation.
Nuclei Templates, Community and Rewards 💎
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.
Try it online with our free AI powered Nuclei Templates Editor by clicking here.
Nuclei Templates offer a streamlined way to identify and communicate vulnerabilities, combining essential details like severity ratings and detection methods. This open-source, community-developed tool accelerates threat response and is widely recognized in the cybersecurity world. Nuclei templates are actively contributed by thousands of security researchers globally. We run two programs for our contributors: Pioneers and 💎 bounties.
Examples

| Use case | Nuclei template |
|---|---|
| Detect known CVEs | CVE-2021-44228 (Log4Shell) |
| Identify Out-of-Band vulnerabilities | Blind SQL Injection via OOB |
| SQL Injection detection | Generic SQL Injection |
| Cross-Site Scripting (XSS) | Reflected XSS Detection |
| Default or weak passwords | Default Credentials Check |
| Secret files or data exposure | Sensitive File Disclosure |
| Identify open redirects | Open Redirect Detection |
| Detect subdomain takeovers | Subdomain Takeover Templates |
| Security misconfigurations | Unprotected Jenkins Console |
| Weak SSL/TLS configurations | SSL Certificate Expiry |
| Misconfigured cloud services | Open S3 Bucket Detection |
| Remote code execution vulnerabilities | RCE Detection Templates |
| Directory traversal attacks | Path Traversal Detection |
| File inclusion vulnerabilities | Local/Remote File Inclusion |
Our Mission
Traditional vulnerability scanners were built decades ago. They are closed-source, incredibly slow, and vendor-driven. Today's attackers are mass exploiting newly released CVEs across the internet within days, unlike the years it used to take. This shift requires a completely different approach to tackling trending exploits on the internet.
We built Nuclei to solve this challenge. We made the entire scanning engine framework open and customizable—allowing the global security community to collaborate and tackle the trending attack vectors and vulnerabilities on the internet. Nuclei is now used and contributed by Fortune 500 enterprises, government agencies, universities.
You can participate by contributing to our code, templates library, or joining our team.
