10 best open-source web application vulnerability scanners
Lots of popular websites have been hacked in the past. Hackers are prolific, often attempting to hack websites and leak information. This is why web application security monitoring is so relevant. And this is where scanners for web application protection come into play.
A software program that conducts automated black-box checking on a web application and detects security bugs is a web application security scanner. Scanners do not view source code; they only conduct practical checks and attempt to detect flaws in security. There are numerous paying and free web application security scanners.
We list the finest free open-source web framework security scanners in this article. In random order, I’m including the resources, so please don’t believe it’s a tool rating.
I am only adding open-source software which can be used to identify security bugs in web applications. I am not adding tools to identify bugs in servers. And don’t mix open-source software and free tools! Various other platforms are available for download, but they do not supply other users with source code. Open-source platforms are those that provide users with source codes so that developers can change the instrument or assist in further development.
This are the finest research methods for open-source web framework penetration.
Grabber is a scanner for mobile applications that can detect multiple web application security vulnerabilities. It conducts scans and says where the weakness is present. The following flaws are detectable:
- Scripting Cross-Site
- Injection of SQL
- Checking Ajax
- Inclusion with file
- Source code analyzer for JS Source Code
- File Search for Backup
Compared to other security scanners, it is not easy, but it is simple and portable. This can only be used to validate small web apps, since scanning large applications requires so much time.
No GUI interface is provided by this method. It does not generate any PDF reports either. This system was meant to be quick and for personal use. I’m not going to suggest it if you are worried about it for technical use.
This tool has been built in Python and, if you like, an executable version is also available. There is a source code, but you can change it according to your needs. The primary script is grabber.py, which calls other modules like sql.py, xss.py or others until run.
Here, download it.
On GitHub, source code.
Another open-source free web security detector and research tool is Vega. You may do safety checking of a web application using this tool. This tool is written in Java and provides an environment based on a GUI. OS X, Linux and Windows are open.
It helps you to set a few preferences when operating with the method, such as the total number of path descendants, the number of child node paths, and the depth and maximum number of requests per second. You will use the Vega Scanner, Vega Proxy and Proxy Scanner, as well as certificate scanning. You can find support in the documents section if you need assistance:
This is the documentation.
Install Here’s Vega.
3. Proxy for Zed Assault
Zed Assault Proxy is known as ZAP as well. This tool is open source and OWASP has developed it. It is available for systems running Windows, Unix/Linux and Macintosh.
I like this tool personally. In online systems, it can be used to discover a wide variety of bugs. The method is very descriptive and easy to use. Even if you are new to penetration testing, you can use this tool to start learning web application penetration testing quickly.
These are ZAP’s main functionalities:
- Proxy intercepts
- Scanner automatic
- Spiders that are conventional but strong
- Support for web sockets
- Support for plug-n-hack
- Help for Authentication
- API based on REST
- Dynamic licenses for SSL
- Support for SmartCard and Customer Digital Certificates
You can either use this tool as a scanner by entering the scanning URL, or you can use this tool to manually run checks on individual sites as an intercepting proxy.

4. To Wapiti
Wapiti is a scanner for web vulnerabilities that helps you to audit your web applications’ protection. By scanning web pages and inserting results, it performs black-box testing. It attempts to insert payloads to see if there is a vulnerability to a script. It supports attacks on both GET and POSTHTTP and detects various vulnerabilities.
The following flaws are detectable:
- Disclosure of File
- Inclusion with file
- Scripting Cross-Site (XSS)
- Detection of order execution
- Injection of CRLF
- Injection of SEL and Injection of XPath
- Poor setup on .htaccess
- Disclosure of Backup File
- Several others
Wapiti is a command-line program, so for beginners, it might not be fast. But it is going to do well for experts. You need to master several commands in order to use this tool, which can be found in the official documents.
Download Wapiti from here with the source code.
W3af is a common attack and audit platform for web applications. This framework aims to provide a stronger research environment for web application penetration. Using Python, it was created. You can recognise more than 200 forms of web server vulnerabilities by using this tool, including SQL injection, cross-site scripting and many others.
A graphical and console interface comes with it. Thanks to its quick gui, you can use it quickly.
I don’t think you are going to face any issues with the tool if you are using it with a graphical interface. All you need to do is pick the options and then activate the scanner. If a website requires authentication, you can also search the session-protected sites using authentication modules.
In our previous W3af walkthrough sequence, we already discussed this method in depth. To learn more about this method, you can read these posts.
From the GitHub repository, you can find the source code here.
Download it here from the official webpage.
WebScarab is a Java-based security platform for HTTP or HTTPS protocol review of web applications. You can expand the tool’s features with usable plugins.
This tool acts like an intercepting proxy; the requests and replies that come to your browser and go to the server can be checked. Until they are processed by the server or browser, you may also change the request or comment.
This tool is not for you if you are a beginner. This tool was developed for those who can write codes and have a clear understanding of the HTTP protocol.
WebScarab offers several features to help penetration testers work on a web application closely and recognise security vulnerabilities. It has a spider which can identify the goal website’s latest URLs automatically. Scripts and the page’s HTML can be quickly removed. The proxy watches the traffic between the server and your browser, and you can use the available plugins to take care of the request and response. The most popular vulnerabilities, such as SQL injection, XSS, CRLF and many other vulnerabilities, can be quickly detected by the accessible modules.
The tool’s source code is available here on GitHub.
Here, download WebScarab.
7. The Skipfish
Another nice web application protection feature is Skipfish. It crawls the website and then scans for different security threats on each page. At the end, the final report is written.
This instrument was composed in C. It is highly designed for the handling of HTTP and minimal CPU utilization. It asserts that without applying a load to the CPU, it can effectively accommodate 2,000 requests per second. When crawling and checking web sites, it uses a heuristic technique and claims to give good quality and less false positives.
For Linux, FreeBSD, MacOS X and Windows, this tool is available.
Install Skipfish or Google Codes for Code here.
Ratproxy is an open-source vulnerability audit tool for web applications that can be used to detect security bugs in web applications. It serves environments such as Debian, FreeBSD, MacOS X and Windows (Cygwin).
All of this method can be read here.

Another common open-source penetration testing instrument is SQLMap. It automates the procedure in the database of a website to identify and exploit SQL injection vulnerabilities. It has a good engine for identification and many helpful features. This way, on a website, a penetration tester will effectively conduct a SQL injection search.
A number of database servers are supported, including MySQL, Oracle, PostgreSQL, Microsoft SQL Server, Microsoft Access, IBM DB2, SQLite, Firebird, Sybase, and SAP MaxDB. Six types of SQL injection strategies are fully supported: time-based blind, Boolean-based blind, error-based, UNION query, stacked and out-of-band queries.
On GitHub, open the source code here.

Another open-source platform freely accessible for web application penetration testing is Wfuzz. For checking against different forms of injections like SQL, XSS, LDAP and many others, it can be used to brute-force GET and POST parameters. It also supports cookie fuzzing, multi-threading, SOCK, proxy, authorization, brute-forcing parameters, multiple proxies and many more.
There is no GUI interface provided by this tool, so you may have to work on the command-line interface.
More about the capabilities of the tool can be found here.
