Replace Calendly with SoloStack

| Custom Branding | Full CSS control (your brand, your design) | Standard ($10/mo) |
The architecture
No black box. You see exactly how bookings flow through your system.
Booking lives as a module in your repo
No SaaS login. No vendor dashboard. Your scheduling system is a folder in your monorepo — right next to your CRM, sales, and marketing.
Config-driven event types
Event types, hosts, availability, and buffer times all live in a single config.json. No UI to navigate. Add a new event type in seconds.
Bookings flow into your CRM
Every booking creates a contact record and logs an event in Neon Postgres. No Zapier, no exports — your CRM knows about every meeting automatically.
Claude Code manages it all
Instead of clicking through Calendly settings, you type what you want. Claude reads the config, updates availability, and deploys changes instantly.

When SoloStack isn't the right fit
We're not for everyone. Here's what you should know before switching.
Calendly is polished out of the box
Calendly's booking pages are beautiful and work instantly. SoloStack gives you full control, but you'll build the booking page with Claude Code. It takes 20 minutes instead of 2 — but you own every pixel.
Enterprise team scheduling
If you have 50+ salespeople who need complex routing, round-robin pools, and admin dashboards, Calendly's enterprise tier is battle-tested for that. SoloStack is built for 1–5 person teams.
Setup requires Claude Code
Calendly is sign-up-and-go. SoloStack requires connecting Google Calendar API credentials and deploying Netlify Functions. Claude Code walks you through it, but it's not zero-effort.
No native mobile app
Calendly has a mobile app for managing bookings on the go. SoloStack bookings show up in Google Calendar (which has a great app), but there's no dedicated scheduling app.
