If you run a salon, spa, barbershop, or a solo beauty practice and you want clients to book online, WordPress has no shortage of options. Two worth putting side by side are Simply Schedule Appointments (SSA) — one of the most established booking plugins in the directory — and StudioSlot, a newer plugin built specifically for beauty and wellness bookings. They solve the same broad problem very differently.
The short version
Choose Simply Schedule Appointments if you need to take payments or deposits today, want Google Calendar sync and Zoom/Meet integration, run group classes, or you're a general business that values a battle-tested, feature-rich tool and don't mind a paid upgrade for the advanced pieces.
Choose StudioSlot if you're a salon, spa, or independent beauty pro who wants a free, genuinely usable booking form that already speaks your language — services, professionals, and clean mobile booking — with a five-minute setup and no monthly fees.

Built for everyone vs. built for you
This is the real difference, and everything else follows from it. Simply Schedule Appointments is designed to work for consultants, tutors, clinics, contractors, and salons alike. That flexibility is a genuine strength — but it means you configure a general tool to behave like a salon booking system: setting up appointment types, mapping availability, and wiring the language to match your business.
StudioSlot starts from the other end. It assumes you offer services (a "Balayage," a "60-Minute Massage"), performed by professionals your clients may want to choose by name, within your business hours. Those concepts are the product, not something you build. The result is a booking form that feels familiar on day one instead of a blank slate you have to shape.
The free versions — both are real
Credit where it's due: SSA's free "Basic" edition is not a crippled demo. It gives you unlimited appointments and calendars, email notifications, multiple appointment types, styling controls, and blackout dates. Many small sites never need to upgrade. That's a fair, usable free tool.
StudioSlot's free version is built on the same philosophy — core booking should be free and complete. You get unlimited services, staff, and appointments; a clean, mobile-first booking form; double-booking prevention; email notices to you, your staff, and your clients; and minimum-notice and booking-window controls. The difference isn't "more vs. less free" — it's what shape the free tool takes. StudioSlot's is salon-shaped.
Where Simply Schedule Appointments wins
Being honest about this matters. SSA is the better choice when:
- You need to take payments or deposits now. SSA's Pro tier supports Stripe and PayPal. StudioSlot's payments are planned, not shipped — if collecting money at booking is a must-have today, SSA wins.
- You want deep integrations. Google Calendar two-way sync, Zoom/Google Meet for virtual appointments, and forms/membership integrations are mature in SSA's paid tiers.
- You run classes or group sessions, or your business isn't beauty at all. SSA's generality is exactly what you want.
- You value a long track record. SSA has years of updates, reviews, and support behind it. StudioSlot is new.
Where StudioSlot wins
- Speed to a salon-ready form. Add services, add your team, set hours, drop in one shortcode. The defaults already assume how a salon books.
- Clients choose their professional. "Book with Maya" is a first-class part of the flow, not a workaround.
- No monthly fees, no upsell walls on the essentials. The free version is meant to run a real business, not push you to upgrade to remove artificial limits.
- Less to configure, less to maintain. Fewer knobs means fewer ways to get the setup wrong.
So which should you install?
If you need payments, calendar sync, or group classes today, or you're not a beauty business, start with Simply Schedule Appointments — it's a proven, capable plugin and its free tier is a fair place to begin.
If you're a salon, spa, barber, or independent beauty professional who wants online booking that fits the way you already work — for free, without wrestling a general tool into shape — StudioSlot was built for exactly that. And because payments, deposits, and SMS reminders are on the StudioSlot roadmap, the gaps above are the ones we're closing next.
