Praytel.

We wire up services with tracing. We emit logs. All in service of observability.

What’s going right, what’s going wrong. How are things wired.

But we silo the data. We set up exporters, stores, and GUIs. But only in our k8s environments.

Praytel unifies logs and tracing on the command line so your development workflow can leverage both.

• leverage logs and tracing as you develop; your tools helping you focus!
• build useful tracing for yourself during development and profit when a fire breaks out in production.
• all without spinning up another docker container on your machine

Praytel is a transparent CLI wrapper: praytel [flags] -- command. It runs one command, captures its stdout/stderr and the OTLP traces and logs it exports, joins them, and prints a single view. There is no daemon, no collector and no leftover files.

praytel -- go test ./...          # append-only stream
praytel --tui -- ./server         # live trace/span tree
