The Verdict
Koalendar is the ultimate free scheduling tool for indie hackers on a budget.

Share unlimited booking links, sync with Google Calendar, Outlook, and iCloud automatically, and scale without touching a credit card. The Pro plan ($6.99/month) adds branding removal, custom colors, and group scheduling—making it accessible for indie founders who need professional features on a shoestring budget.
