dapr
Dapr is a portable runtime for building distributed applications across cloud and edge, combining event-driven architecture with workflow orchestration.
We decided to use Azure Container Apps as a managed Kubernetes platform because it offers everything we need for our project, with acceptable limitations. During the process, we realised that Microsoft includes managed Dapr as part of the service—and we decided to use it. Why? I explain below—and I still don't regret it.

coroot
Coroot is an open-source APM & Observability tool, a DataDog and NewRelic alternative. Metrics, logs, traces, continuous profiling, and SLO-based alerting, supercharged with predefined dashboards and inspections.
I'm currently working with Coroot, which is an open source project trying to create a solution for this issue of logs and other telemetry sources being too much for any team to reasonably have time to parse manually. Data is automatically imported using eBPF and Coroot will provide insights into RCA (with things like mapped incident time-frames) to help with anything overlooked in dumps.
GitHub here - hope the tool can help some folks in this thread! https://github.com/coroot/coroot

An actor-based Framework with network transparency for creating event-driven architecture in Golang. Inspired by Erlang. Zero dependencies.
