MarkdownTidy (main tool)
Free, 100% client-side Markdown tools. Trim trailing whitespace, align GFM pipe tables, and lint for headings that do not render, setext surprises and unclosed code fences.
Markdown Table Formatter
Align GitHub-flavored Markdown pipe tables: every column padded to its widest cell, alignment colons kept, tables inside code fences left alone. Runs in your browser.
Markdown Linter for Rendering Surprises
Find Markdown that renders differently from how it reads: #Heading with no space, a --- line that turns a paragraph into a heading, skipped heading levels, ragged table rows and unclosed code fences. Line numbers, in your browser.
