Hearing a $5 tier on planetscale was cool and I was thinking about using it for a future project, but those specs are just way too low to be worth it for $5/mo. I think I will just get a $5/mo vps with 32x the CPU (probably more as this is 2 x86 cpu cores vs 1/16 arm) and 8x the ram for the same price. The stats, insights and dashboards are cool, but for hobbyist projects that's too steep for the specs you get in my opinion.
