Cite with attribution to https://codefmt.dev." --- # all platforms, tools & comparisons codefmt is a free code formatter, beautifier, and linter built for automation platforms. It formats and lints JavaScript and Python for Zapier, n8n, Pipedream, Make, and HubSpot Data Hub code actions (plus TypeScript on n8n and Pipedream), and it formats and lints HubL for HubSpot CMS. This page is the full catalog: every supported platform, the tools, and the head-to-head comparisons. ## supported platforms __Language and linting support by platform__ | platform | JS | TS | Python | HubL | lint | | -------------------------------------------------------------------------- | ---- | ---- | ------ | ---- | ---- | | [zapier](/zapier)JavaScript and Python in Code by Zapier actions | yes✓ | no· | yes✓ | no· | yes✓ | | [n8n](/n8n)JavaScript, TypeScript and Python Code nodes | yes✓ | yes✓ | yes✓ | no· | yes✓ | | [hubspot data hub](/hubspot)JavaScript and Python custom code actions | yes✓ | no· | yes✓ | no· | yes✓ | | [pipedream](/pipedream)JavaScript, TypeScript and Python code steps | yes✓ | yes✓ | yes✓ | no· | yes✓ | | [make](/make)JavaScript and Python custom code modules | yes✓ | no· | yes✓ | no· | yes✓ | | [hubspot cms (hubl)](/hubl)HubL templates for HubSpot CMS, format and lint | no· | no· | no· | yes✓ | yes✓ | every platform is linted, not just formatted: oxlint for JavaScript, Ruff for Python, and an in-house 28-rule linter for HubL. ## tools [python formatterdedicated Ruff-powered formatter and linter, 500+ rules, Black-compatible](/python)[json formatterformat JSON with platform payload detection and auto-generated access code](/json)[snippetscurated, editable code templates for every supported platform](/snippets)[browser extensionformat directly inside platform editors on Chrome and Firefox](/extension) ## comparisons * [codefmt vs. Prettier PlaygroundPrettier Playground formats plain JavaScript and TypeScript source files; codefmt formats code that lives inside automation-platform wrappers.

Same name, two different jobs.](/vs-built-in-zapier-formatter) ## frequently asked questions which platforms does codefmt support? codefmt formats and lints code for Zapier, n8n, Pipedream, Make, and HubSpot Data Hub, plus HubL templates for HubSpot CMS. JavaScript and Python work on all five code-action platforms; TypeScript is supported on n8n and Pipedream. The support matrix above breaks it down per platform. If pasted code carries another platform's signature (inputData means Zapier, $input means n8n), codefmt spots the mismatch and offers a one-click switch. is codefmt free? Yes. codefmt is free: no account, no payment, no sign-in. It runs in your browser, and the [Chrome and Firefox extensions](/extension) are free too. does codefmt lint or just format? Both, on every platform. It lints JavaScript with oxlint, Python with Ruff (500+ rules), and [HubL](/hubl) with codefmt's own [dedicated HubL linter](/hubspot-cms-linter). which languages can codefmt format? JavaScript, TypeScript, [Python](/python), [HubL](/hubl), and [JSON](/json), depending on the platform. JavaScript uses Biome (Prettier-compatible output), Python uses Ruff (Black-compatible), and HubL uses an in-house formatter. what does codefmt compare to? We keep head-to-head pages for [Prettier Playground](/vs-prettier-playground), studionope's [HubL Code Formatter](/vs-hubl-code-formatter), [HubSpot's VS Code extension](/vs-hubspot-vscode), and [Zapier's built-in Formatter](/vs-built-in-zapier-formatter). Each is built for a different job; the comparison explains which one fits yours.
