Supanote vs Rentry: The Modern Markdown Paste & Publishing Alternative

Rentry.co is a popular minimalist markdown pastebin known for simple text sharing and edit codes. However, modern developers and technical writers frequently need full syntax-highlighted code blocks, KaTeX math formula rendering, structured CSV/log viewers, terminal cURL piping, password encryption, and native AI integration via MCP. Supanote provides the clean simplicity of Rentry combined with modern developer infrastructure.
