QuotaGuard

QuotaGuard is a web app that puts hard guardrails on serverless usage and cost across AWS Lambda, API Gateway, and related event sources. Instead of just alerting after the damage is done, it enforces configurable budgets and rate limits per function, stage, tenant, or API key. Teams define policies like “max 2M invocations/day,” “cap concurrency to 50,” or “block traffic when spend hits $300 this month,” with safe fallbacks (return cached responses, queue requests, or degrade features). It ships with a lightweight agentless setup using cloud-native telemetry and policy-as-code so changes are reviewable and auditable. The dashboard highlights the exact trigger (deployment, bad retry loop, bot traffic, misconfigured cron) and provides one-click mitigations. This is not magic: it won’t fix bad architecture, but it will prevent surprise bills and outages caused by unbounded scaling.
