  description

  Format and lint your code directly inside automation platform editors — no copy-paste to VS Code required.
  
  Supported platforms:
  
  • Zapier (Code by Zapier — JavaScript and Python)
  • n8n (Code nodes — JavaScript and Python, on n8n.io and n8n.cloud)
  • Pipedream (Code steps — JavaScript and Python)
  • Make / Integromat (JavaScript modules)
  • HubSpot Operations Hub (custom code actions — JavaScript)
  • HubSpot Design Manager (HubL templates — HTML + HubL, CSS + HubL, and module.js)
  
  How it works:
  
  1. Open a code editor on any supported platform
  2. Click the codefmt popup button, right-click → "Format with codefmt", or press the keyboard shortcut (Cmd/Ctrl+Shift+F
  by default)
  3. Your code is formatted and written back to the editor instantly
  4. Any lint diagnostics are reported in a toast notification
  
  Features:
  
  • Platform-aware formatting — understands each platform's code structure (async wrappers, globals, return styles,
  line-width conventions)
  • Auto-detects JavaScript, Python, and HubL (including HTML, CSS, and JavaScript contexts inside HubSpot Design Manager)
  • Instant lint diagnostics — oxlint for JavaScript (50-100× faster than ESLint) and ruff for Python
  • Powered by oxfmt — a Prettier-compatible formatter written in Rust, with the same output you already know
  • Powered by ruff — the Python formatter and linter used by the Python community's largest projects
  • Configurable formatting — print width, quote style, semicolons, trailing commas, bracket spacing, arrow parens, and more
  • Sync settings from codefmt.dev with one click — configure on the web, use in the extension
  • Customizable keyboard shortcut — default Cmd/Ctrl+Shift+F, remap from chrome://extensions/shortcuts
  • Per-tab badge — shows "fmt" on supported sites so you know the extension is live
  • Works with Monaco and CodeMirror 6 editors (the engines used by all supported platforms)
  • Right-click context menu entry on supported sites
  • 50 KB code size limit per format request
  • 30-second request timeout with automatic retry on transient network failures
  
  Privacy and data handling:
  
  • No accounts, no cookies, no tracking, no telemetry
  • Your formatting preferences are stored locally in your browser only
  • When you trigger a format, the code currently in your editor is sent over HTTPS to codefmt.dev/api/format, processed
  on-the-fly, and returned formatted. Processing uses short-lived in-memory buffers and ephemeral temporary files that are
  deleted immediately after the response is sent — nothing is persisted to any database, logged, or shared with third
  parties
  • The extension only runs on the supported platform domains listed above (plus codefmt.dev for the optional settings-sync
  feature)
  • Full privacy policy: https://codefmt.dev/privacy
  
  Security:
  
  • Manifest V3 with minimal permissions (activeTab, contextMenus, storage, scripting)
  • Strict hostname matching — only the exact supported domains are allowed to trigger format requests
  • Hardened content security policy on the extension popup
  • Bridge script uses a per-session authentication token so page scripts cannot hijack editor read/write
  • No remote code execution — all scripts are bundled in the extension package
  
  Built on:
  
  • oxfmt — the Rust-based, Prettier-compatible formatter from the Oxidation Compiler project (oxc.rs)
  • oxlint — 50-100× faster than ESLint, same rules and same output
  • ruff — the Rust-based Python formatter and linter (astral.sh/ruff)
  
  Source code and configuration:
  • Web formatter: https://codefmt.dev
  • Support and docs: https://codefmt.dev/about

  Format and lint your code directly inside automation platform editors. No copy-paste to VS Code or any other editor required.
  
  Supported platforms:
  
  - Zapier (Code by Zapier action: JavaScript and Python)
  - n8n (Code nodes: JavaScript and Python, on n8n.io and n8n.cloud)
  - Pipedream (Code steps: JavaScript and Python)
  - Make / Integromat (JavaScript code modules)
  - HubSpot Data Hub (custom code actions: JavaScript and Python)
  - HubSpot **CMS** / Design Manager (HubL templates with **HTML** and **CSS** contexts, plus module.js)
  
  How it works:
  
  - Open a code editor on any supported platform.
  - Use any of three ways to format:
      * Click the codefmt icon in your browser toolbar, then press *format code*.
      * Right-click and select *Format with codefmt* (format only) or *Fix with codefmt (format + safe fixes)* (format plus safe lint fixes plus organize imports).
      * Press the keyboard shortcut (Cmd+Shift+F on Mac, Ctrl+Shift+F on Windows and Linux by default).
  - Your code is formatted and written back to the editor instantly.
  - Any lint diagnostics are reported in a toast notification with their count.
  
  Features:
  
  - Platform-aware formatting that understands each platform's code structure (async wrappers, globals, return styles, line-width conventions)
  - Auto-detects JavaScript, Python, and HubL (including **HTML**, **CSS**, and JavaScript contexts inside HubSpot Design Manager)
  - Instant lint diagnostics powered by oxlint for JavaScript (50 to **100** times faster than ESLint) and Ruff for Python
  - JavaScript and TypeScript formatting powered by Biome, with Prettier-compatible output
  - Python formatting and linting powered by Ruff
  - HubL formatting and linting via a custom in-house formatter built for HubSpot **CMS** templates
  - *Fix with codefmt* right-click action that applies safe Biome lint fixes and organize-imports in one pass (added in 1.3.3)
  - Configurable formatting: print width, quote style, semicolons, trailing commas, bracket spacing, arrow parens, **JSX** quote style, quote properties, bracket same line, and organize imports
  - Sync settings from codefmt.dev with one click. Configure on the web, use in the extension.
  - Customizable keyboard shortcut, default Cmd+Shift+F / Ctrl+Shift+F. Remap from about:addons → codefmt → Manage → Shortcuts.

  - 30 second request timeout with automatic retry on transient network failures
  
  Privacy and data handling:
  
  - No accounts, no cookies, no tracking, no telemetry
  - Your formatting preferences are stored locally in your browser only
  - When you trigger a format, the code currently in your editor is sent over **HTTPS** to codefmt.dev/api/format, processed in memory, and returned formatted. Processing uses short-lived in-memory buffers and
  ephemeral temporary files that are deleted immediately after the response is sent. Nothing is persisted to any database, logged, or shared with third parties.
  - The extension only runs on the supported platform domains listed above (plus codefmt.dev for the optional settings-sync feature)

  - Hardened content security policy on the extension popup
  - Per-session authentication tokens prevent page scripts from hijacking editor read/write operations
  - No remote code execution. All scripts are bundled in the extension package and are plain, human-readable JavaScript with no minification or build step.
  
  Built on:
  
  - Biome (biomejs.dev): Rust-based, Prettier-compatible formatter that powers JavaScript and TypeScript output
  - oxlint (oxc.rs): 50 to **100** times faster than ESLint, with a familiar rule set
