Costly

Costly is an open-source SDK designed to eliminate redundant spending in usage. Key features include: * Real-time API call logging with zero latency * Seven automated waste detectors for common inefficiencies * Detailed cost audits (prompt bloat, model overkill, duplicate queries) * Centralized dashboard for spend, audits, and savings * Easy one-command setup for rapid integration Costly integrates directly into your application, wrapping your client to log every call. Unlike standard dashboards that merely report expenditure, Costly proactively identifies the root causes of financial waste, such as unnecessarily large models for simple tasks, repeated system prompts across many calls, or costly failed requests. Its detectors analyze usage patterns to pinpoint areas for optimization. Developers gain a clear overview of their usage patterns, cost breakdowns by feature and model, and a bill forecast based on current trends. The platform provides actionable recommendations to reduce costs and improve efficiency, moving beyond just showing you what you spent. This tool is ideal for engineering teams and developers leveraging large-scale APIs who need precise cost control and performance optimization. It helps ensure resources are used effectively, transforming raw data into actionable insights for significant savings and more efficient operations.
