Interactive UIs

Browse SNOMED CT concepts in a terminal UI or a local web GUI.

Terminal UI experimental!

To reduce the size of the default sct binary, the interactive terminal UI is an optional feature that needs to be enabled at build time with the tui feature flag. If you built sct without it, you can rebuild with: cargo install --path . --features tui

Docs: sct tui

sct tui --db snomed.db

Three-panel layout:

  • Top-left: Hierarchy browser
  • Bottom-left: Search box + results
  • Right: Full concept detail

Keybindings: / search, Tab switch panels, ↑↓ navigate, Enter select, q quit.

Browser UI experimental!

Docs: sct gui

The browser-based UI is another optional feature that needs to be enabled at build time with the gui feature flag. If you built sct without it, you can rebuild with: cargo install --path . --features gui

sct gui --db snomed.db
# Opens http://127.0.0.1:8420 in your browser

sct gui                  # --db defaults to ./snomed.db or $SCT_DB
sct gui --port 9000      # custom port
sct gui --no-open        # start server but don't open browser

Single-page app with three tabs:

  • Detail — full concept view: preferred term, FSN, synonyms, attributes, parents, children count
  • Graph — D3 force-directed graph showing the focal concept (centre), its parents (above), and up to 50 children (below). Draggable nodes, zoom/pan, click any node to navigate.
  • Hierarchy — browse the 19 top-level SNOMED hierarchies

Bound to localhost only — never accessible from the network.
