You can find some additional installation variations in the Installation Guide.
brew tap caffix/amass brew install amass
sudo snap install amass
docker pull caffix/amass
docker run -v OUTPUT_DIR_PATH:/.config/amass/ caffix/amass enum -d example.com
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.
go install -v github.com/OWASP/Amass/v3/[email protected]
Use the Installation Guide to get started.
Go to the User's Guide for additional information.
See the Tutorial for example usage.
See the Amass Scripting Engine Manual for greater control over your enumeration process.

"Accenture’s adversary simulation team has used Amass as our primary tool suite on a variety of external enumeration projects and attack surface assessments for clients. It’s been an absolutely invaluable basis for infrastructure enumeration, and we’re really grateful for all the hard work that’s gone into making and maintaining it – it’s made our job much easier!"
- Max Deighton, Accenture Cyber Defense Manager
"For an internal red team, the organisational structure of Visma puts us against a unique challenge. Having sufficient, continuous visibility over our external attack surface is an integral part of being able to efficiently carry out our task. When dealing with hundreds of companies with different products and supporting infrastructure we need to always be on top of our game.
For years, OWASP Amass has been a staple in the asset reconnaissance field, and keeps proving its worth time after time. The tool keeps constantly evolving and improving to adapt to the new trends in this area."
