Security Scanning / Mobile App Sec
The most concrete split between Black and ARMO is the pricing model: Black runs on free and open-source, while ARMO uses freemium. That shapes how predictable your monthly spend is and how much of the cost sits in infrastructure versus per-seat or per-event fees. Beyond the headline, Black carries low lock-in (oss python formatter) and free and open-source; ARMO carries medium lock-in (kubescape oss backed) and freemium. Black is a fit when you are mobile. ARMO is a fit when you are mobile. The honest trade-off: Black is explicitly not for hobby projects; ARMO is explicitly not for hobby projects. On the product side, Black is described as Security Scanning / Mobile App Sec tool for developers. Specializes in Python Formatter, and ARMO is described as Security Scanning / Mobile App Sec tool for developers. Specializes in Kubernetes Security. Common Black use cases include vulnerability scanning in ci/cd. Common ARMO use cases include vulnerability scanning in ci/cd.
Quick take
Black is for mobile; ARMO is for mobile; decide on pricing model.

Choose Black if you want a fully free, open-source option and can handle self-hosting or self-support.
Not for: Hobby projects
Choose ARMO if its freemium pricing model fits your budget shape better than Black's free model, and you are mobile.
Not for: Hobby projects

Direct comparison is hard. Black is free and open-source, so licence cost is zero though you pay in operational effort. ARMO uses freemium, so it costs money in exchange for managed service. Which is cheaper depends on how much engineering time you value.
Migration from Black to ARMO is plausible because Black has low lock-in (oss python formatter). You would still have to map config, permissions and integrations to ARMO's model. Plan for dual-run and rollback.
Both tools tie at 5/5 for developer experience on our scoring. The real difference will show up in your specific workflow, not the headline rating. A one-hour spike on both is the fastest way to decide.
ARMO targets the same best-fit audience as Black (mobile). Note that ARMO is explicitly not for hobby projects, so it only replaces Black if you are outside that exclusion. The lock-in profile differs (low vs medium), which is the main thing to weigh.
