Observability for serverless functions

Firefly is an open-source observability framework, it provides an overview of serverless function health via metrics and traces. Firefly provides automated instrumentation and deployment of a telemetry pipeline, and displays relevant data in easy to use dashboards.

We designed Firefly for small teams that need observability for their serverless functions, but don't want to commit to a full on SaaS solution. We tried to strike a balance between the ease of use of an SaaS solution and the low cost of a DIY solution. Read our case study for a more in depth look at Firefly!
