Product Designer using Sveltekit

I have built one product designer similar to https://pqina.nl/pintura/ using Sveltejs, Using it you can build a custom T-Shirt designer, or Mobile Cover designer. if somebody is interested I can share the code.

I am confused, whether to make it open source or publish at some marketplace.

• Please suggest me some marketplace where I can sell it for $29/lifetime instead of instead of $149/year of Pintura.

• I am not going immediate open source because it requires a lot of promotion and contributors to get some traction.

WHY?

• It has possibility to create a full fledge Figma, Canva.

• penpot.app raised it's Series-A just after Figma was aquired by Adobe.

This has a huge opportunity, I have used and seen its power. Its newer to the community.
