nomore403 is an innovative tool designed to help cybersecurity professionals and enthusiasts bypass HTTP 40X errors encountered during web security assessments. Unlike other solutions, nomore403 automates various techniques to seamlessly navigate past these access restrictions, offering a broad range of strategies from header manipulation to method tampering.
Before you install and run nomore403, make sure you have the following: - Go 1.15 or higher installed on your machine.
Grab the latest release for your OS from our Releases page.
If you prefer to compile the tool yourself:
git clone https://github.com/devploit/nomore403
cd nomore403
go get
go build
To edit or add new bypasses, modify the payloads directly in the payloads folder. nomore403 will automatically incorporate these changes.

Command line application that automates different ways to bypass 40X codes.
Usage:
  nomore403 [flags]
Flags:

  -d, --delay int             Specify a delay between requests in milliseconds. Helps manage request rate (default: 0ms).
  -f, --folder string         Specify the folder location for payloads if not in the same directory as the executable.
  -H, --header strings        Add one or more custom headers to requests. Repeatable flag for multiple headers.
  -h, --help                  help for nomore403
      --http                  Use HTTP instead of HTTPS for requests defined in the request file.
  -t, --http-method string    Specify the HTTP method for the request (e.g., GET, POST). Default is 'GET'.
  -m, --max-goroutines int    Limit the maximum number of concurrent goroutines to manage load (default: 50). (default 50)
