Rendering HTML & Inline Images Across Non-GUI Shells
Nuncio provides seamless HTML and image rendering mechanics across Terminal TUI, POSIX CLI, and AI MCP agents without compromising security.
Converts HTML to clean ANSI text via `html2text` with tracking pixels blocked. High-resolution images render inline using Kitty Graphics Protocol, iTerm2 Inline Images, or Sixel graphics. Press o to view in system browser.
nuncio mail show <id> prints formatted plain text. Use --html for markdown output, --raw-html for piping to `w3m`/`lynx`, or --open for browser trigger.
Converts HTML to token-efficient Markdown for LLM prompt contexts. Image attachments are passed as Base64 multimodal vision content blocks to Vision LLMs.
Nuncio automatically strips 1x1 tracking GIF/PNG pixels (`<img src="...track..." width="1" height="1">`), remote CSS `@import` triggers, and external script tags before rendering email payloads.
