Skill Issues Killer is an open-source platform focused on backend development projects with automated tests. It emphasizes real-world scenarios and community support. It does not offer subscription-based access, expert-led courses, live workshops, curated learning paths, or progress tracking/assessments, which are all must-have features for the Frontend Masters Learning Platform concept. Therefore, it does not match the concept.

It handles edge cases much better and the API is actually documented properly.

Honestly, after trying both, Competitor B wins hands down. Better customer support, cleaner interface, and they don't nickel and dime you for every feature.
