We started Sideband with a simple frustration: component data is the connective tissue of every PCB project, yet it’s the part most likely to be locked inside a tool you can’t fully control.

Sideband is a desktop app for Windows, macOS and Linux that keeps your symbols, footprints, 3D models and parametric data in one place — and lets you take all of it with you, any time, in open formats.

What it does today

• A unified component library with full-text search across every field.
• A PCB viewer and inventory that stay in sync with your Altium libraries.
• An ODBC connector so Altium reads straight from Sideband.
• LCSC / EasyEDA import to bootstrap parts in seconds.

The one promise

Whatever happens to your subscription, your data is always exportable. No lock-in, no hostage-taking — that contract holds through cancellation.

More soon. If you’d like early access, join the beta.
