Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The tool is primarily built for JavaScript and lacks robust support for other languages like Python or Go.
Documentation is sparse on how to configure custom cost models, leaving users to reverse-engineer the codebase.
Estimation processes become slow and resource-intensive when dealing with extensive model deployment scenarios.
Initial configuration requires setting up multiple environment variables and dependencies which can be overwhelming.
