Replace Calendly with SoloStack

Calendly charges $10–16/user/mo for a booking page + calendar sync. SoloStack gives you the same thing — built on Google Calendar API + Netlify Functions — for $0/mo. Unlimited event types. Full design control.

Manages the entire booking system via plain English — no UI needed

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.

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.

Common questions

Yes. SoloStack's booking pages are Astro components — you can embed them anywhere on your site. Unlike Calendly's iframe embed, your booking widget is a native part of your page with full design control. No external scripts, no brand watermarks.
Yes. SoloStack integrates directly with the Google Calendar API. When someone books a meeting, it creates a calendar event, checks for conflicts in real time, and respects your working hours. No middleware, no third-party sync — it reads and writes to your calendar directly.
Yes. The booking config supports multiple hosts with individual availability rules. You can set up round-robin routing so meetings are distributed across your team. Calendly charges $16/user/mo for this — SoloStack does it for $0.
The booking page queries the Google Calendar API for your available slots based on your configured working hours, buffer times, and existing events. Clients see a clean date picker and available time slots — just like Calendly, but hosted on your own domain.
SoloStack detects the visitor's timezone automatically via the browser and displays all available slots in their local time. The Google Calendar event is created with proper timezone data so both parties see the correct time. No manual timezone selection needed.
Yes. When a booking is confirmed, SoloStack sends a confirmation email via Resend. You can add reminder emails (24h before, 1h before) as Netlify scheduled functions. Full control over the email template, timing, and content — no per-email fees.
