Need Help About Supabase

hello seniors. it's been 7 months since i run on survival mode. money is short. and i learn coding with ai for these 7 months to hopefully make my life better.

please help, i have a problem

currently i'm using supabase. but free tier only limits to 2 active project... but i'm currently need to run 5-6 different projects. all prototypes for potential client. (i feel like i need to build prototype in front. more effort, but it's equivalent to my lack of portofolio). none have paid any money, none deal, but the next 2 weeks is the crucial time which every project either got a deal or not (after that i will subscribe to supabase and have no problem)

but currently i have a problem

5-6 project. but only 2 active project limit in supabase free tier... my question is: can i only activate a project when developing and/or demo-ing it to the client? so that i can use that 2 active project limit beautifully and everything is still safe?

i ask grok and it said it is okay and can be done. but grok is an ai, and an ai don't need to make ends meet.
