Ask HN: How to Open Source?

I have developed a privacy-focused survey tool called BlockSurvey. I bootstrapped it over last 18 months and I've just crossed over $1k in MRR. Right now, I'm working to make it open source. It's more difficult to do since there are 10+ repos and plenty of hosting configurations. How does one do it?

Should it be a phased out process with UI first and then services. The stack is Angular JS for UI, Cloudfunctions and Realtime DB from Firebase. For the way forward, should I accept donations for futher development and contributions for community members who would help with? or should I get into a strategic parternship with existing privacy focused tech players.
