Text & Comparison Tools

Developers spend a lot of time working with plain text: log lines, config files, commit messages, and documentation. These tools help you match patterns, see exactly what changed between two versions, and check how Markdown will render.

Regex Tester

Test JavaScript regular expressions and inspect every match.

Text Diff

Compare two text blocks line by line.

Slug Generator

Create clean URL slugs from titles and phrases.

Markdown Preview

Write Markdown and preview the rendered document safely.

Regex without guesswork

The Regex Tester lists every match with its index and capture groups, using the same JavaScript engine your browser code runs on. That makes it easy to confirm a pattern before putting it in a validator or a search-and-replace.

Seeing changes clearly

Text Diff compares line by line and marks additions and removals. It is useful for comparing two versions of an environment file or spotting what changed in a pasted log.
