CapShield
The hard-cap gap is one of the most consistent complaints in the corpus, dating back 7+ years and still unresolved as of Oct 2025. From MaxBarraclough (HN): 'AWS does not support a pre-pay model, and to my knowledge there's no water-tight way of capping your costs.' From capybara_2020: 'An old account got hacked... bill of $50k-$70k.' fabian2k: 'I would not use AWS for private stuff because of this, it is simply not worth it to risk huge bills to me personally.' Also covers Vercel pricing surprises in the corpus and the new dimension of model API spend.
