Its a great idea but as someone pointed out, it seems more like a feature than a full product. You would also benefit from targeting a specific market.

I create a website builder for the real estate sector and I started off by open sourcing it:

This gave me some credibility in the sector and I have now been contacted by many people wanting help with their website.

I want to launch a SaaS that focuses on the real estate sector so if you are open to collaborating I'll be happy to discuss that.
