chrome-devtools-mcp vs open-design
The two are close in size: 51.0k stars for chrome-devtools-mcp, 94.2k for open-design. Over the days we have tracked them chrome-devtools-mcp moved +8.4% and open-design +19.3%, so open-design is growing faster right now.
open-design leads on context depth and customization. chrome-devtools-mcp does not take any axis by a clear margin.
Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
Where they stand today

Six axes, head to head
Each axis runs 0 to 5. The label under a score is what that project's own docs claim, not a category average.
| Axis | chrome-devtools-mcp | open-design |
|---|---|---|
Context depth How much of your codebase it sees before it answers: the open diff, the diff plus related files, or the whole repository. | ●●●●● Browser-only context | ●●●●● Project-wide access |
Noise control How it keeps output volume down — severity thresholds, deduplication, incremental runs over new commits only. | ●●●●● No noise controls | ●●●●● No noise controls |
Customization How far it bends to your team: custom rules, prompts, style guides, per-path config. | ●●●●● Config flags available | ●●●●● Plugins & design-system |
Privacy Whether your code stays on your own infrastructure: fully local, self-hostable, or cloud API only. | ●●●●● Self-hostable (opt-outs) | ●●●●● Self-hostable |
Model freedom Whether you can point it at any provider, or it is wired to one. | ●●●●● Bring-your-own model | ●●●●● Bring-your-own-key |
Setup ease What it takes to get a first useful run out of it. | ●●●●● One-command start | ●●●●● Quickstart 3 commands |
Which one to pick
Pick chrome-devtools-mcp if…
Advanced browser debugging — use this when you need an agent to interact with and inspect a live Chrome browser for reliable automation, debugging, and performance traces.
Pick open-design if…
Local-first — run agent-native design workflows on your laptop with plugins and a DESIGN.md-driven design system, and export real files without relying on a single closed service.
- Context depth: Project-wide access (4/5 against 1/5)
- Customization: Plugins & design-system (5/5 against 3/5)
