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.
Sigilweaver Loom is currently in Private Beta. The codebase is not yet public, but binaries and documentation are published to test the distribution pipeline and gather feedback. Expect rough edges, breaking changes, and evolving APIs. See the Roadmap for progress and what's coming.
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
