Vercel and Netlify functions are some of the most popular solutions when it comes to the Jamstack backend.
In a survey conducted by O'Reilly in June 2019, 30% of the respondents named harder debugging, and 25% named observability to be the biggest challenges in adopting serverless technologies. In the same report, about 17% mentioned a lack of tools. It's not always easy to debug serverless applications.
If you're using Vercel or Netlify functions, it's even more challenging because there are even fewer tools available. No tracing tool supports these serverless platforms out of the box.
This allows tracing the Netlify Functions and the Vercel Functions serverless providers, respectively.
