httpx
is a fast and multi-purpose HTTP toolkit that allows running multiple probes using the retryablehttp library. It is designed to maintain result reliability with an increased number of threads.
Features
- Simple and modular code base making it easy to contribute.
- Fast And fully configurable flags to probe multiple elements.
- Supports multiple HTTP based probings.
- Smart auto fallback from https to http as default.
- Supports hosts, URLs and CIDR as input.
- Handles edge cases doing retries, backoffs etc for handling WAFs.

Installation Instructions
httpx
requires go1.20 to install successfully. Run the following command to get the repo:
go install -v github.com/projectdiscovery/httpx/cmd/httpx@latest
This project is in active development. Expect breaking changes with releases. Review the changelog before updating. |
This project was primarily built to be used as a standalone CLI tool. Running it as a service may pose security risks. It's recommended to use with caution and additional security measures. |

Error Page Classifier and Filtering
The Error Page Classifier and Filtering feature aims to add intelligence to the tool by enabling it to classify and filter out common error pages returned by web applications. It is an enhancement to the existing httpx capabilities and is geared towards reducing the noise in the results and helping users focus on what matters most.

Screenshot
Latest addition to the project, the addition of the -screenshot
option in httpx, a powerful new feature that allows users to take screenshots of target URLs, pages, or endpoints along with the rendered DOM. This functionality enables the visual content discovery process, providing a comprehensive view of the target's visual appearance.
Rendered DOM body is also included in json line output when -screenshot
option is used with -json
option.
🚩 Usage
To use the screenshot feature, simply add the -screenshot
flag to your httpx command:
httpx -screenshot -u https://example.com
-screenshot
option is versatile and can be used to capture screenshots for domains, subdomains, and even specific paths when used in conjunction with the -path
option:
httpx -screenshot -u example.com
httpx -screenshot -u https://example.com/login
httpx -screenshot -path fuzz_path.txt -u https://example.com
Using with other tools:
subfinder -d example.com | httpx -screenshot
🌐 System Chrome
By default, httpx will use the go-rod library to install and manage Chrome for taking screenshots. However, if you prefer to use your locally installed system Chrome, add the -system-chrome
flag:
httpx -screenshot -system-chrome -u https://example.com
📁 Output Directory
Screenshots are stored in the output/screenshot directory by default. To specify a custom output directory, use the -srd
option:
httpx -screenshot -srd /path/to/custom/directory -u https://example.com
⏳ Performance Considerations
Please note that since screenshots are captured using a headless browser, httpx runs will be slower when using the -screenshot
option.
httpx
as a library
Using httpx
can be used as a library by creating an instance of the Option
struct and populating it with the same options that would be specified via CLI. Once validated, the struct should be passed to a runner instance (to be closed at the end of the program) and the RunEnumeration
method should be called. A minimal example of how to do it is in the examples folder
Notes
- As default,
httpx
probe with HTTPS scheme and fall-back to HTTP only if HTTPS is not reachable. - The
-no-fallback
flag can be used to probe and display both HTTP and HTTPS result. - Custom scheme for ports can be defined, for example
-ports http:443,http:80,https:8443
- Custom resolver supports multiple protocol (doh|tcp|udp) in form of
protocol:resolver:port
(e.g.udp:127.0.0.1:53
) - The following flags should be used for specific use cases instead of running them as default with other probes:
-ports
-path
-vhost
-screenshot
-csp-probe
-tls-probe
-favicon
-http2
-pipeline
-tls-impersonate
Acknowledgement
Probing feature is inspired by @tomnomnom/httprobe work
httpx
is made with
