Installation

You can find some additional installation variations in the Installation Guide.

Prebuilt Packages

Simply unzip the package
Put the precompiled binary into your path
Start using OWASP Amass!

Homebrew

brew tap caffix/amass
brew install amass

Snapcraft

sudo snap install amass

Docker Container

Install Docker
Pull the Docker image by running docker pull caffix/amass
Run docker run -v OUTPUT_DIR_PATH:/.config/amass/ caffix/amass --version

The volume argument allows the Amass graph database to persist between executions and output files to be accessed on the host system. The first field (left of the colon) of the volume option is the amass output directory that is external to Docker, while the second field is the path, internal to Docker, where amass will write the output files.

The wordlists maintained in the Amass git repository are available in /wordlists/ within the docker container. For example, to use all.txt:

docker run -v OUTPUT_DIR_PATH:/.config/amass/ caffix/amass enum -brute -w /wordlists/all.txt -d example.com

From Sources

Install Go and setup your Go workspace
Download OWASP Amass by running go get -v github.com/OWASP/Amass/v3/...
At this point, the binary should be in $GOPATH/bin
