CodeBeautify alternatives

People look for a CodeBeautify alternative when the ads get in the way, when they'd rather not send code to a server, or when they need something that works offline. Weigh where your input is processed, how many ads a page carries, and whether the site covers the languages and formats you use most.

We make BrowserUtils, one of the sites below. Facts checked .

  1. BrowserUtils

    Ours

    299 developer tools, one per page, that format JSON, XML, HTML, CSS, SQL, JavaScript and Python and convert between JSON, YAML, XML, CSV and TOML, mostly in your browser and with no third-party ads. It has far fewer tools than CodeBeautify, no file upload or save-and-share links in its formatters, and isn't open source.

    Best for: Ad-free formatting and conversion in the browser

    • In the browser
    • No sign-up
    • No third-party ads
    • Web, works on mobile
    • Not open source
    • Free
    • 299 tools

  2. IT-Tools

    An open-source (GPL-3.0), ad-free set of about 85 browser-based utilities, including JSON, SQL and XML prettifiers, JSON/YAML/TOML/XML converters, hashing and JWT parsing, that you can self-host with one Docker command. It has no HTML, CSS or JavaScript beautifier.

    Best for: An ad-free toolbox you can self-host for a team

    • In the browser
    • No sign-up
    • No ads
    • Web (self-hostable with Docker)
    • Open source
    • Free
    • About 85 tools

  3. CyberChef

    GCHQ's open-source (Apache-2.0), fully client-side "Cyber Swiss Army Knife": 500+ operations, JSON, XML, SQL, CSS and JavaScript beautifiers among them, that you chain into recipes such as From Base64 → Gunzip → JSON Beautify and share as one URL. The recipe interface takes longer to learn than a single-purpose page.

    Best for: Multi-step decoding and data transformations

    • In the browser
    • No sign-up
    • No ads
    • Web (downloadable to run offline)
    • Open source
    • Free
    • 500+ operations tools

  4. Prettier Playground

    The official browser playground for Prettier, the open-source (MIT) formatter, covering JavaScript, TypeScript, CSS, SCSS, Less, HTML, Vue, Markdown, YAML, GraphQL and JSON with Prettier's own options. It only formats: there are no viewers, validators or converters.

    Best for: Formatting web code exactly the way Prettier will

    • In the browser
    • No sign-up
    • No ads
    • Web
    • Open source
    • Free
    • 1 tool (code formatter)

  5. DevToys

    A free, open-source (MIT) desktop app for Windows, macOS and Linux with 30 offline tools (JSON, SQL and XML formatters, encoders, hash generators, regex and XML/XSD testers) that can suggest a tool from what's on your clipboard. It has to be installed, so it won't help on a locked-down machine.

    Best for: Offline use on your own computer

    • On your machine
    • No sign-up
    • No ads
    • Desktop app (Windows, macOS, Linux)
    • Open source
    • Free
    • 30 built-in tools, more as extensions

  6. Transform.tools

    An open-source (MIT) site of about 60 converters that turn JSON into TypeScript, Go, Rust, Kotlin, Java or Zod types and handle SVG/HTML to JSX, GraphQL and JSON Schema; a few, such as TypeScript to JSON Schema, run on its server. It doesn't format or validate.

    Best for: Generating types and schemas from sample JSON

    • Browser and server
    • No sign-up
    • No ads
    • Web
    • Open source
    • Free
    • About 60 converters tools

Where CodeBeautify is better

  • Far more tools: about 770 on its All Tools page against 299 here, including converters BrowserUtils doesn't have, such as Excel to HTML, XML to Java, SQL to CSV and an OPML viewer.
  • Save & Share stores your input and gives you a link to send, and a free login keeps your saved files in one list. BrowserUtils' formatters have no save or share links.
  • Its viewers load input from a file or a remote URL (File and URL buttons), so you can inspect an API response without copying it. BrowserUtils' formatters take pasted text only.
  • A Chrome extension (about 10,000 users) opens its tools from the browser toolbar.

Where BrowserUtils is better

  • No third-party ads. CodeBeautify's JSON viewer loads Freestar ad units, including a sticky adhesion banner, a billboard and a video player.
  • Formatters run in your browser. CodeBeautify's JSON and SQL formatters are client-side too, but its Python formatter sends your code to its server; BrowserUtils formats Python locally.
  • Paste anything into the homepage box or the ⌘K palette and it recognizes JSON, JWTs, Base64, timestamps, colors and hashes, then opens the right tool with your input already in it.
  • A developer-only set of 299 tools, so search and categories aren't mixed with the name generators and fun-text tools CodeBeautify lists on its homepage.
