Monitoring serverless apps can be challenging due to the lack of visibility into error details. Sentry provides code-level visibility for serverless projects, offering stack traces, user-agent information, and metadata around issues, allowing developers to quickly resolve problems. The platform also offers deep-linking to CloudWatch or Stackdriver logs from issue details screens. With its new SDKs for Python and Node, developers can start capturing errors and relevant information in minutes, streamlining the debugging process.
