tilt-dev/tilt is a tool that defines the development environment for microservice apps running on Kubernetes in code and brings them all up at once. The README explains that the `tilt up` command runs a development environment tailored to your team. The latest release tag published by this repository is v0.37.8.
The point of this tool is to bundle the repetitive manual work that comes with handling several services locally into a single flow. After a code change it detects the files, builds the container image, and updates the running environment to the latest state, chaining these steps together automatically. The README describes this as the same thing as running docker build && kubectl apply or docker-compose up directly. The license is Apache-2.0, the main language is Go, and the star count is 10114. The repository was started on August 7, 2018.
One thing to watch is that the provided records contain no changelog for what v0.37.8 changed. In the evaluation scores, the novelty, technology, and quality items are blank, and only the momentum item is low, at 1.6 out of 10. With that score the only remaining signal, it is unclear which direction things will move next, rather than what the project does well today. To judge whether running multiple services with a single command fits your team's size and environment constraints, you have to check the changes in each release directly.
