Build vs Fork Verdict: KINDA (the core, yes. the polish, no)

Why fork Sling Free instead of vibe-coding a When I Work clone?

The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For When I Work, build a small shift schedule, availability form, and swap approval workflow. The hard boundary is mobile apps, time clock, notifications, scheduling edge cases, and support, plus compliance, payroll, and regulated integrations.
