[OSS GAP] Booking / Appointments #booking #appointments #self-hosted #smb

Pain: Local businesses need a working booking link and reminders, not per-seat scheduling software built for sales teams. “A place for small business owners, brokers, and lenders to connect, share real funding stories, and learn about merchant cash advances, business loans, and fintech lending. Ask que” — reddit (https://www.reddit.com/r/alternativelending/)

Why now: Small teams in 2026 are cutting tool spend and refusing extra platform debt. Calendly, Acuity Scheduling, Square Appointments are strong products, but they are packaged for bigger companies than salon and other small teams. That makes a smaller, self-hosted wedge in booking / appointments unusually easy to explain.

Tiny wedge: Availability rules for salon and other small teams without Calendly-style pricing and platform weight.

Why this wins: Replaces recurring Calendly spend with a boring self-hosted alternative for salon and other small teams.

Scope cut: Skip sales pipeline automation and video meeting platform in v1.

Stack: Node.js + Express + SQLite.
