PasteBom - January 2026

PasteBom is a shareable interactive PCB Bill of Materials viewer. Upload a board file and get a link to an interactive viewer with a searchable BOM table. Supports seven EDA formats: KiCad, EasyEDA, Eagle, Altium, GDSII, Gerber, and ODB++.

The viewer renders front and back board views on stacked HTML5 canvases with click-to-highlight for nets and components, per-layer visibility toggles, pan/zoom/rotate, and dark mode. Uploads can be marked secret or left public on a shared feed. Each paste gets an SVG thumbnail for embedding.

The whole stack is Rust:

• pcb-extract — A parser library that reads .kicad_pcb, EasyEDA JSON, Eagle XML, Altium .pcbdoc, GDSII, Gerber, and ODB++ files into a common intermediate representation.
• pastebom-server — An Axum/Tokio HTTP server handling multipart uploads, S3-backed storage, and serving the viewer.
• pastebom-viewer — A Yew/WASM frontend compiled with Trunk, rendering interactive board views on canvas with path caching for performance.
