Booking pages & meeting polls

I want to pick an open-source replacement for Calendly, Doodle (letting people book a time with you, or picking a meeting time together). Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - Cal.com: Cal.diy is the free community edition of Cal.com. It lets you share a page where others pick a meeting time, and connects to your calendar so you are not double-booked. You run it on your own server, and its makers advise it for personal use only. Team and company features were removed from this edition. [Advanced setup; runs on a server you set up; replaces fully; MIT; https://github.com/calcom/cal.com] - Tymeslot: Tymeslot is scheduling software that lets people share their availability and let guests book meeting times. It is meant for individuals and teams who want to run their own booking system on their own server. [Advanced setup; runs on a server you set up; replaces fully; AGPL-3.0; https://github.com/Tymeslot/tymeslot] - Nextcloud Polls: Polls is an add-on for Nextcloud, a self-hosted file and collaboration server, that lets you create polls to find a meeting time or pick options. It is for people and teams who run their own Nextcloud and want to schedule without Doodle. [Advanced setup; runs on a server you set up; replaces partly; AGPL-3.0; https://github.com/nextcloud/polls] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/booking-pages.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/booking-pages.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
