Syntaxify

Local syntax highlighting for code blocks on web pages.

Syntaxify makes plain code blocks easier to read directly on the web page. It detects common programming languages, applies a calm syntax theme, handles dynamically inserted content, and avoids blocks that are already highlighted by the site. 🔥 KEY FEATURES 🔥 1️⃣ automatic syntax highlighting on regular web pages; 2️⃣ JavaScript, Python, JSON, HTML, SQL and other popular languages; 3️⃣ light, dark, and system-aware themes; 4️⃣support for dynamically inserted code and open Shadow DOM roots; 5️⃣ page, site, and domain-pattern exclusions; 6️⃣ a context-menu formatter for selected JSON, curl, or irregularly indented code; 7️⃣ restoration of original page markup when highlighting is removed. ✅LOCAL AND PRIVATE Syntaxify processes code blocks and the current page URL locally in Chrome. It does not send page content, URLs, selections, settings, or history to the developer or third parties. It has no analytics, telemetry, advertising, remote code, or runtime network requests. When you explicitly format selected text, Syntaxify keeps up to five history entries in local Chrome storage. Settings and exclusion rules use Chrome sync storage and may be synchronized by Chrome according to your browser settings; the Syntaxify developer cannot access them. 🆓No account or subscription is required. 💗Syntaxify works offline. 🫣Access to local `file://` pages remains disabled until you enable “Allow access to file URLs” in Chrome.
