About this shelf
Dev tools on this site are not a second Product Hunt for every CLI. This shelf is engineering workflow products we list next to the design catalog — today that includes diagrams, whiteboards, and related utilities that help you explain a system or run a team. It is deliberately separate from UI kits you install in a codebase.
If you came here for a component library, go back to UI kits. If you came here to draw an architecture diagram or run a whiteboard in a design-eng review, stay. The Diagrams filter is the absorbed niche; the parent view is the whole engineering-adjacent list.
Featured picks are tools we would put in a review doc or a planning session. The grid is the rest. We will not pretend this is a complete developer-tool index. It is the slice that sits next to craft and shipping on this directory.
Pair with coding agents when the job is writing code, and with design systems when the job is tokens. This page is the leftover that is still a tool and still useful to the same audience.
Questions
- Why is this separate from UI kits?
- Kits are things you install in a product UI. This shelf is workflow and diagram tools, not Button components.
- Do you list VS Code extensions?
- Only if they are catalogued. Coding agents and AI IDEs have their own category.
- What is the Diagrams filter?
- Whiteboards and diagram tools absorbed into this parent shelf.
- Is this an exhaustive engineering directory?
- No. It is the engineering-adjacent slice we keep next to the design and AI catalog.
