Dagster

Dagster ranks 136th overall in the developer tools category with a composite score of 55 out of 100. The organization describes itself as An orchestration platform for the development, production, and observation of data assets, which frames how developers first encounter the brand on GitHub, in package registries and in search results.

Its developer reach and documentation and learning material come across as strong, and are what most developers will notice first when they land on the organization. By contrast, its developer experience and code quality look minimal today, which is the clearest area where a small amount of focused work would visibly move the needle. Taken together, the picture is of a company whose public developer surface is neither uniformly polished nor uniformly weak, and where different audiences (contributors, integrators, evaluators) will likely form very different first impressions depending on which door they walk through.

Dagster maintains 67 public repositories on GitHub, built primarily in Python, Shell and HTML, which together have collected 17,832 stars and drawn contributions from 110 developers outside the core team, 14 of those repositories have seen commits in the last 90 days, a useful proxy for how much of the codebase is genuinely alive rather than archived.
