Every part your team designs with, on one data model

Sideband is a desktop app that holds your components, symbols, footprints, 3D models, boards and suppliers in one place, and syncs them live into Altium via DBLib.

Why Sideband

Stop scattering parts across spreadsheets and DBLibs

One model on your desktop that keeps every engineer, and Altium, working from the same parts.

One model

Symbol, footprint, 3D model, suppliers and storage all hang off a single component record.

A desktop app

Download it for Windows. Your library lives in a database on your own machine.

Built for Altium

A native DBLib endpoint. Altium sees every change the moment you make it.

30-day free trial

The full app, no card needed. Early adopters lock in founding pricing for launch.

The whole bench, in one app

Real symbols, footprints and boards

Inspect any board without opening Altium

A real Altium .PcbDoc, rendered from its layer stack. Toggle copper, silkscreen, paste and mechanical layers.

Features

Everything you need to run a component library

Schematic symbols, outbound webhooks and the rest of the toolkit.

Component Library

One canonical record per component — parameters, lifecycle, MPNs/SPNs and a linked symbol, footprint and 3D model.

Learn more

Schematic Symbols

Every symbol rendered and searchable — pin tables, per-part previews — with the original SchLib bytes preserved for Altium.

Learn more

PCB Footprints

Real pad geometry from the PcbLib, a per-layer primitive inventory, and the attached 3D model one tab away.

Learn more

PCB Viewer

A WebGL viewer fed by the PcbDoc itself — 2D and 3D, five board themes, real drill barrels, and a measure tool in millimetres.

Learn more

Pin ↔ Pad Mapping

Automatic validation between symbol pins and footprint pads, with unmatched designators surfaced.

Learn more

Boards & BOMs

Import an Altium project and read everything — BOM, nets, placements, stackup, schematic — with JLCPCB-ready exports.

Learn more

Inventory

A tree of your storage with scannable placement IDs that survive moves — the label you printed last month still resolves.

Learn more

Label Printing

Design and print barcode / QR labels for parts and locations that deep-link straight back into the app.

Learn more

Suppliers & Manufacturers

Track manufacturer part numbers and supplier part numbers against every component, with real brand data.

Learn more

Altium ODBC Connector

A real ODBC driver for Altium's DBLib, kept live by change-data-capture — one MSI, one connection string.

Learn more

EasyEDA / LCSC Import

Import a fully-formed component — symbol, footprint and 3D model — straight from LCSC by part number.

Learn more

Library Import

SchLib and PcbLib archives — or SQLite, PostgreSQL, MSSQL, Excel and CSV — through a wizard with field mapping and dedup.

Learn more

Connectors

Scriptable inbound/outbound integrations — enrich parts from CSV, Excel, SQL or APIs, or push your catalogue to ERP/PLM.

Learn more

Cron Scheduling

Run any connector on a cron expression — validated in plain English — plus built-in maintenance jobs.

Learn more

Webhooks

Push components outbound as signed JSON webhooks the moment they change — compliant with the Standard Webhooks spec.

Learn more

REST API

116 routes across the whole library, documented as OpenAPI 3.1 — and pleasant to drive from ten lines of Python.

Learn more

Symbol Restyler

Saved themes — colours, fonts, per-text overrides — applied across thousands of symbols in one pass, originals untouched.

Learn more

Command Palette

A VS Code-style ⌘K palette plus fully customisable keyboard shortcuts for every action.

Learn more

Search

Words in any order, typos forgiven, sound-alikes found — "10uF 25V 0805" works however it comes out.

Learn more

Takeout

One click exports the whole local database and every attached file as an open archive, with an optional portable PostgreSQL dump. No lock-in.
