Looking for a
Calendly alternative?
Own one instead.

— the angle

Every list of Calendly alternatives, Calendly competitors, or apps like Calendly shows you the same trade: pick a cheaper SaaS, sign another monthly contract, accept a feature cap. We don't do that.

NoSubz is a self-hosted Calendly alternative where you buy the actual source code. You get a private GitHub repo with a production-ready self-hosted booking system — public booking pages, Google Calendar sync, Stripe payments, ICS invites, admin dashboard — watermarked to your name and license. Run it on the free tiers of Vercel + Supabase. Free-tier infrastructure, lifetime use, $0/month running cost for most businesses.

If you've been searching for an open-source Calendly alternative or a free Calendly alternative because every paid option has a per-seat catch — this is the logical endpoint. One $$149 payment. No subscription. The code is yours.

— 01 / why

Renting scheduling software never pays off.

Calendly Teams
$16 per seat / month
5 seats over 5 years = $4,800. You still own nothing. Cancel and you lose every booking history, every embed, every integration.
Cheaper SaaS alternatives
$5–$15 / month
Even the budget alternatives chase you with seat-tier upgrades. Most cap features just above where you actually need them.
NoSubz Booking Scheduler
$149 once, forever
You own the source. Host on free-tier Vercel + Supabase. Modify anything. Use it for unlimited bookings, unlimited team members, unlimited event types. Forever.
— 02 / inside

What's in the box.

Public booking pages
Multiple event types. Per-type duration, buffer, pricing, availability rules. Your branding, your domain.

Stripe payments per booking
Charge for slots. Use YOUR Stripe account — we never touch the money. Configurable refund + cancellation rules.
ICS calendar invites
Automatic on booking. Optional reminder emails 24h and 1h before each slot.
Admin dashboard
Password-protected. Manage bookings, blocked dates, payment status, refunds. Mobile-friendly.
Source code + private repo
Full Next.js 15 + Supabase TypeScript codebase. Private GitHub repo, watermarked to your name + license.

Common questions.

Is this really an open-source Calendly alternative?
It's source-code-available, single-license. Source is yours to read and modify; license forbids redistribution. Think of it as "you-own-a-copy", which is the practical benefit most people want from "open source" — the ability to inspect, fix, and self-host.
Is there a free Calendly alternative?
Yes — and you've found the catch already. Free options gate features at exactly the wrong moment (team sync, custom branding, payment collection). This is paid-once, then free forever to run.
What's the self-hosted booking system stack?
Next.js 15 (App Router) + Supabase (Postgres) + Stripe + Google Calendar API + Resend. All standard. All run on free tiers for the realistic small-business volume.
Will it work without me being a developer?
Yes, if you can paste API keys into a Vercel dashboard. The README is step-by-step. Or pay $$99 for the install service — we screen-share and wire it up on your accounts.
What about updates and security patches?
12 months of free updates included. Security patches stay free, lifetime. Major version upgrades (v2, v3) priced at a steep discount for existing owners.
Can I get a refund?
14 days, no questions, as long as you haven't published your watermarked copy.
