Opaque cost metrics and unpredictable platform expenses
5/10 MediumVercel's usage dashboard shows metrics like 'Fluid Active CPU' and 'ISR Writes' without clear documentation on how they impact costs or how to optimize them. Developers pay subscription fees but lack visibility into what drives spending, making budgeting impossible.

Collection History
No clear usage limits or feature restrictions are specified, which makes it hard to gauge its sufficiency for serious projects... Opaque pricing and hosting details: The lack of explicit pricing info or usage limits makes it hard to plan budgets.
Since Resend doesn't disclose the cost of this add-on, it's a hidden variable you should account for early. You might start with volume-based pricing in mind, only to realize later: You need analytics → upgrade to Pro. You need longer retention → upgrade to Scale. You need a dedicated IP → upgrade to Enterprise or pay for the add-on.
The official documentation lacks clear guidance on the cost per thread. Questions about thread creation costs, management, deletion, and whether these can be controlled via the API remain unanswered.
developers share stories of $400 surprise bills, $1,200 monthly invoices for what they expected to be a $20/month service... The most frustrating aspect is not the cost itself -- it is the unpredictability. With usage-based pricing, a traffic spike (which should be a good thing) becomes a financial risk.
Without proper monitoring, AWS costs can spiral out of control... AWS pricing can be difficult to understand.
My usage dashboard says my two most-used things are 'Fluid Active CPU' and 'ISR Writes'. I just pay them $20/mo and pray none of those usages go over 100% because I wouldn't have the first clue why I'm going over if it does.
