Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Tilt

Dev environment as code.

What we like

Fast rebuilds and live updates, even for compiled languages and changed deps. Can run containers independently or through existing k8s configs. Works with Helm, podman, local processes. Tiltfile controls the environment config written in a Python-like language. Local web UI with custom buttons e.g. seed database.

What we don't like

No project announcements since it was acquired by Docker in 2022, but there are still regular releases. Stable, but with regular fixes? Not a bad place to be.

ArkFlow

Stateless stream processing.

What we like

Takes inputs (MQTT, Kafka, HTTP, database queries, Nats), then processes the data (JSON, SQL, batch, VRL), and sends the result to an output (Kafka, MQTT, HTTP, stdout, Nats). Can buffer in memory to apply backpressure. Uses the Rust Tokio async runtime and builds to a single binary for deployment.

What we don't like

Fewer connectors compared to other stream processors like Bento. Missing databases as output options.
