We’ve all heard the horror stories of unsupervised AWS instances that lead to million-dollar invoices. Even when we’re not talking about millions, you probably know the feeling of usage-based bills far more expensive than you thought. Lago now helps you prevent those scenarios. With budget & usage alerts, you can put hard edges around consumption and billing.

The feature is basically a multi-layered warning system. You can track:

Lifetime spend for the entire subscription—ideal for free trials that should never exceed, say, a total of $100.

Current-period spend so finance knows when a customer hits 80 percent of this month’s credits and engineering can act before overages accrue.

Metric-based spend in amount or usage units, meaning you can send an alert when a user has used up 1 million API calls or $100 of API calls.
