Did you sell the app in the end? Or shut it down?

We (coders.fail) have some Shopify apps. If you stay on it, have a good USP and marketing, it can definitively work. I know some people who did it and are happy. We didn't focus enough on it and are currently working on something else.
I'm always of the opinion to not put your eggs all in one basket, at least when you have some eggs. Starting out and working on some apps that give you some income, seems like a good approach.
If you have some questions, let me know.

This one. Supports more languages and self-hosting.
Works in many environments and has many integrations for desktop apps as well.

We've never had to transfer accounts, but also had our fair share of issues with Chargebee. For a bigger and complicated project (a marketplace with a mix of one-time and subscription payments with a variety of add-ons and German billing systems) they were willing to improve and change some of their APIs.
During the work with their dev team, we noticed multiple bugs in the APIs, pre-existing or freshly introduced ones, failure to notice API changes of third-parties they relied on and failure to deliver on-time and what was discussed.

The end result was APIs that 20 seconds to calculate prices, webhooks that took multiple minutes to arrive, changed behaviour of production APIs without publishing a new version and the shutdown of their Stripe bank transfer integration, since they realised they cannot support it any more.

After this experience, we decided, it would not be wise to be a long-term client of them.
The amount of frustration experienced and time lost because of them, probably doesn't fit in one post :)

We've tried to use free tier services for as long as possible. Like the free tier, betterstack.com for monitoring has been enough for us.
Cloudflare takes care of a load of load and other features, like custom domain caching.
Most of the costs we have come from tools like Google Workspace and Notion, where we pay per seat and cannot really share it.
Things like VPN accounts and 1Password family is shared more easily with friends or partners.

As @robreckham and I are collaborating as #codersfail in our projects and indie hacker journey, we are kind of already sharing all the tools.
The Hetzner VPS we also user for our personal freelancing projects and help each other out with our skills.

Of course. wip.co users are not our target audience :)
Thanks for the feedback.

Reviving your domain zarrasvand.com without putting in any work :)

Got it. I understand it doesn't make sense for you.
I'm just shopping around for opinions about the editor UX in general, even they might not use the final product.
Thank you :)

Did you get a chance to try the editor as well? Was it clear what you had to do?

Thank you, that is good to hear. I was worried :)
What do you think about the editor?
