Smap is a replica of Nmap which uses shodan.io's free API for port scanning. It takes same command line arguments as Nmap and produces the same output which makes it a drop-in replacament for Nmap.
- Scans 200 hosts per second
- Doesn't require any account/api key
- Vulnerability detection
- Supports all nmap's output formats
- Service and version fingerprinting
- Makes no contact to the targets
go install -v github.com/s0md3v/smap/cmd/smap@latest

Smap is also avaible on Homebrew.
brew install smap
Smap takes the same arguments as Nmap but options other than
-iL are ignored. If you are unfamiliar with Nmap, here's how to use Smap.
smap 127.0.0.1 127.0.0.2
You can also use a list of targets, seperated by newlines.
smap -iL targets.txt
188.8.131.52 // IPv4 address
example.com // hostname
184.108.40.206/8 // CIDR
Smap supports 6 output formats which can be used with the
-o* as follows
smap example.com -oX output.xml
If you want to print the output to terminal, use hyphen (
-) as filename.
oX // nmap's xml format
oG // nmap's greppable format
oN // nmap's default format
oA // output in all 3 formats above at once
oP // IP:PORT pairs seperated by newlines
oS // custom smap format
oJ // json
Note: Since Nmap doesn't scan/display vulnerabilities and tags, that data is not available in nmap's formats. Use
-oSto view that info.
smap -p21-30,80,443 -iL targets.txt
Since Smap simply fetches existent port data from shodan.io, it is super fast but there's more to it. You should use Smap if:
- vulnerability detection
- a super fast port scanner
- results for most common ports (top 1237)
- no connections to be made to the targets
You are okay with
- not being able to scan IPv6 addresses
- results being up to 7 days old
- a few false negatives
