Sieve

Sieve lets you decide what Grasshopper loads before it opens.

Instead of launching Grasshopper with all plugins, you launch it through Sieve and either:

• Select plugins manually for this session, or
• Choose a saved “environment” (a preset list of plugins) tailored to a specific workflow.

Grasshopper then starts with only those plugins, which means:

• Faster startup times

• Fewer conflicts and version issues

• A cleaner canvas focused on the tools you actually need

• Better team communication when everyone shares the same environments

  (especially useful if you have a large plugin library with different workflows)

Key features

Environment presets

• Create and name multiple Grasshopper environments.
• Each environment stores a list of plugins to load.

Manual plugin selection

• Browse your installed Grasshopper plugins and tick only what you need.
• Ideal for quick tests or one-off setups.

Multiple plugin locations

• Scans typical Grasshopper plugin folders and any custom paths you add.

Planned features (roadmap)

In future releases, Sieve aims to:

• Backup environments & plugin sets – save and restore plugin configurations or environments.
• Document-aware loading – drag & drop a Grasshopper file and load only the plugins required for that document.

👉 Open-source & community-driven

Sieve is an open-source project developed by ToolWorksLAB, and it grows with the community.

If you want to help make it better, more reliable, and more widely usable, you’re very welcome to:

• Open issues for bugs or feature requests
• Contribute code via pull requests
• Share feedback from your own workflows (urban, robotics, fabrication, etc.)
