Welcome to Sigilweaver Loom
The visual data pipeline platform you always wished existed.
Sigilweaver Loom is both a desktop application for building visual data workflows and a self-hostable platform for collaboration and organization. Design pipelines by dragging tools onto an infinite canvas, wire them together, and watch your data flow.
The Platform
| Component | What It Does |
|---|---|
| Studio | Desktop app for visual workflow design |
| Server | Execution engine powered by Polars |
| Hub | Orchestration platform for teams and automation |
Use Studio + Server for single-user local development. Add Hub when you need centralized storage, scheduling, or team collaboration.
Why Sigilweaver Loom?
- Visual clarity: See your entire pipeline at a glance - branches, joins, transformations laid out spatially
- Full power: Backed by Polars - lazy evaluation, blazing speed, production-ready performance
- No row limits: Process what your hardware can handle, not what a SaaS vendor allows
- Self-hosting first: Your data never leaves your infrastructure
