Configuring
By default, no configuration is needed.
But there are some optional environmental variables that you can set to give you access to some additional checks, or to increase rate-limits for some checks that use external APIs.
API Keys & Credentials:
Key
Value
GOOGLE_CLOUD_API_KEY
A Google API key with the PageSpeed Insights and Safe Browsing APIs enabled (get here). Runs the quality and Safe Browsing checks
SHODAN_API_KEY
A Shodan API key (get here). Runs the host names, server info and vulnerabilities checks
CLOUDMERSIVE_API_KEY
A Cloudmersive API key (get here). Adds the Cloudmersive website scan to the threats check
TRANCO_API_KEY
A Tranco API key (get here). Raises the Tranco rate limit for the rank check
TRANCO_USERNAME
Your Tranco account email, used with the key above
GITHUB_TOKEN
A GitHub token (get here). Raises the GitHub rate limit for the social presence check
CERTSPOTTER_TOKEN
A CertSpotter API token (get here). Raises the CertSpotter rate limit for the subdomains check
Configuration Settings:
Key
Value
PORT
Port to serve the API, when running server.js (e.g. 3000)
API_ENABLE_RATE_LIMIT
Enable rate-limiting for the /api endpoints (e.g. true)
PUBLIC_API_TIMEOUT_LIMIT
The timeout limit for API requests, in milliseconds (e.g. 25000)
API_CORS_ORIGIN
Enable CORS, by setting your allowed hostname(s) here (e.g. example.com)
API_DISABLED_CHECKS
Comma-separated list of checks to disable (e.g. trace-route,ports)
API_ENABLED_CHECKS
If set, only these checks will run (e.g. get-ip,ssl,dns,headers)
API_BLOCKED_HOSTS
Hosts that must never be scanned (e.g. lan.example.com,192.168.0.0/16)
CHROME_PATH
The path the Chromium executable (e.g. /usr/bin/chromium)
DISABLE_GUI
Disable the GUI, and only serve the API (e.g. false)
PUBLIC_API_ENDPOINT
The endpoint for the API, either local or remote (e.g. /api)
All values are optional.
You can add these as environmental variables. Either put them directly into an .env file in the projects root, or via the Netlify / Vercel UI, or by passing to the Docker container with the --env flag, or using your own environmental variable management system
Note that values prefixed with PUBLIC_ are read by the frontend at build time, so you need to rebuild after changing them
You'll need Node.js (v22.22.3+ or v24.16+) installed, plus yarn as well as git.
Some checks also require chromium, traceroute and dns to be installed within your environment. These jobs will just be skipped if those packages aren't present.
Community
Contributing
Contributions of any kind are very welcome, and would be much appreciated.
For Code of Conduct, see Contributor Covenant.
To get started, fork the repo, make your changes, add, commit and push the code, then come back here to open a pull request. If you're new to GitHub or open source, this guide or the git docs may help you get started, but feel free to reach out if you need any support.
Reporting Bugs
If you've found something that doesn't work as it should, or would like to suggest a new feature, then go ahead and raise a ticket on GitHub.
For bugs, please outline the steps needed to reproduce, and include relevant info like system info and resulting logs.
Supporting
The app will remain 100% free and open source.
But due to the amount of traffic that the hosted instance gets, the lambda function usage is costing about $25/month.
Any help with covering the costs via GitHub Sponsorship would be much appreciated.
It's thanks to the support of the community that this project is able to be freely available for everyone :)
