Hidden costs to watch for	Eco dynos ($5/mo flat) are personal-account only and not available to Enterprise/Team customers Postgres Essential tier has no fork/follow, no HA, and only 99.5% uptime SLA -- a hidden reliability cliff vs. Standard Add-on overages (Postgres row/connection limits, Redis memory limits) can force an unplanned upgrade to the next tier Performance dynos require an established payment/billing history before they can be provisioned Private Spaces and Shield Private Spaces carry a substantial network-isolation premium (2-3x) over common-runtime equivalents Heroku Postgres Advanced tier pricing is not published; requires contacting sales	Renewal prices are 3-6x higher than signup/intro price after the first term (e.g. StartUp $2.99 -> $17.99/mo) Storage and visit caps are enforced per plan tier; exceeding them can trigger upsell prompts Free domain / free migration offers are time-limited promotions, not permanent 12-month (or longer) prepay is required to get the lowest advertised intro rate
