Nerine
Nerine is a static web application testing tool. You write a script that defines the request to send and the response you expect back. Nerine sends the request and logs anything that does not match. Each test case can modify the request, compare the response to what you expect, and extract values from the response for the test cases that follow. Point Nerine at a directory of scripts and it runs all of them. Nerine was built for web application regression testing in CI/CD pipelines, and the same scripts work for uptime monitoring and for watching security headers and .well-known/security.txt for changes.
Nerine
$25.00 for a one year license
Nerine is for one person testing one application. It runs up to ten scripts per pass, one at a time, against the targets written into the scripts, and logs the results to the console. Nerine is licensed for your own work, which includes personal research, learning, and bug bounties. If you are paid for the engagement, you need Nerine Professional.
Nerine Professional
$250.00 for a one year license
Nerine Professional is for consultants running the same tests against many client systems. Write a script once and run it against a single server or against a whole list of them, without editing the script for each target. Professional raises the limit to a thousand scripts per pass and runs ten of them at a time. Debug logging is available for the runs that need explaining. Nerine Professional is licensed for professional services work as well as personal research.
Nerine Enterprise
$2,500.00 for a one year license
Nerine Enterprise is for running Nerine as infrastructure. It handles a million scripts per pass and runs up to a hundred of them at a time. Logging is structured JSON with selectable levels, so the output drops into whatever you ship logs to. Enterprise can also read variables from the environment, including the license key, which lets a container or a CI runner run Nerine without writing the key to disk. Nerine Enterprise is the only version licensed for general commercial use, and the only one you may install where more than one person can reach it.
