codefmt — format automation code

Code formatter and linter for Zapier, n8n, Pipedream, Make, and HubSpot. Format JavaScript, Python, and HubL directly inside the platform editor. No copy-paste.

Features & Capabilities

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.
  • Per-tab badge shows fmt on supported sites so you know the extension is live
  • Works with Monaco and CodeMirror 5 / 6 editors, which are the engines used by all supported platforms
  • 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 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)
  • 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
  • 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
  • Ruff (astral.sh/ruff): Rust-based Python formatter and linter used by major Python projects

Is codefmt — format automation code Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

codefmt — format automation code requires a few sensitive permissions. Exercise caution before installing.
