Real-time error tracking and deploy-aware alerts for a fraction of the price. Rollbar ~$149/mo → MeterCall pay-per-call, ~99% less. Catch exceptions, group them smart, ping the right human the instant prod breaks. Wiring this yourself is dev-time you don't have — an agent installs the SDK, tunes the alerts, and watches it 24/7 at /agents.html?module=rollbar-replacement.
