FreeFormatter alternatives

FreeFormatter.com went offline in July 2026 when its owner retired it, and the domain now shows a parked page of sponsored links. If you relied on its formatters, XSD validator, XPath tester or string escapers, check which of those a replacement covers, and whether it processes your data in the browser or on a server.

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

  1. BrowserUtils

    Ours

    Covers most of FreeFormatter's everyday tools (JSON, XML, HTML and SQL formatters, a JSON validator, XML/JSON/CSV/YAML converters, Base64 and URL encoding, hashes, HMAC, MIME types, HTML entities) in your browser with no third-party ads. It has no XSD validation, XPath tester, XSLT or Java regex engine, so it doesn't replace FreeFormatter's XML schema tools.

    Best for: FreeFormatter's JSON, SQL and encoding tools without the ads

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

  2. CodeBeautify

    The closest like-for-like replacement, with about 770 tools including XML, JSON, HTML and SQL formatters, XML-XSL transformation, escape/unescape for Java, C#, JavaScript, JSON, XML, CSV and SQL, and a credit card validator. Its XML validator doesn't check against an XSD, its Python formatter runs on its server, and pages carry heavy ads, including a sticky banner and a video player.

    Best for: The widest FreeFormatter-style tool set on one site

    • Browser and server
    • Sign-up optional
    • Heavy ads
    • Web and Chrome extension
    • Not open source
    • Free
    • 700+ tools (our count)

  3. CyberChef

    Open-source (Apache-2.0) and fully client-side, with 500+ operations covering XPath and CSS-selector queries, JSON/XML/SQL/CSS/JavaScript beautifiers, string escaping, HTML entities, hashing, HMAC and Base64. You chain operations into recipes, which is more flexible than FreeFormatter's one-form-per-tool pages but slower to learn.

    Best for: Escaping, encoding and XPath queries without uploading data

    • In the browser
    • No sign-up
    • No ads
    • Web (downloadable to run offline)
    • Open source

  4. DevToys

    A free, open-source (MIT) desktop app for Windows, macOS and Linux whose 30 offline tools include JSON, SQL and XML formatters, an XML/XSD tester, a JSONPath tester and text escaping, with an XSD generator available as an extension. You have to install it, and it has no XSLT tool.

    Best for: Validating XML against an XSD offline

    • On your machine
    • No sign-up
    • No ads
    • Desktop app (Windows, macOS, Linux)
    • Open source
    • Free

  5. Liquid Technologies Online Tools

    Free online tools from XML-editor maker Liquid Technologies: XML validation against XSD, RelaxNG or Schematron, XML-to-XSD and XSD-to-XML generation, XML and JSON formatters, and JSON Schema validation. Input goes to its servers, which it says may retain it, and is capped at 512 KB.

    Best for: XSD, RelaxNG and Schematron validation

    • On their servers

  6. IT-Tools

    Open-source (GPL-3.0), ad-free and browser-based, with about 85 utilities including JSON, SQL and XML prettifiers, JSON/YAML/TOML/XML converters, a regex tester, a crontab generator, URL encoding and HTML entities; you can self-host it with Docker. It has no XSD validation, XPath tester or language-specific escapers.

BrowserUtils vs FreeFormatter

Where FreeFormatter is better

  • Validated XML against an XSD you pasted or uploaded, reporting fatal errors, errors and warnings. BrowserUtils' XML formatter only checks well-formedness.
  • Had an XPath 2.0/3.0 tester with namespace support, an XSLT transformer and an XSD generator (Russian Doll, Salami Slice or Venetian Blind designs). BrowserUtils has none of these.
  • Tested regular expressions against Java's Pattern class and generated Quartz cron expressions. BrowserUtils' regex tester uses JavaScript regex and its cron tool uses the standard five fields.
  • Every formatter and validator accepted a file upload as well as pasted text. BrowserUtils' formatters take pasted text only.

Where BrowserUtils is better

  • It's online. FreeFormatter.com now shows a parked page of sponsored links, while BrowserUtils covers its JSON, XML, HTML and SQL formatters, JSON validator, Base64 and URL encoders, hashes, HMAC, MIME type list and HTML entities.
  • Your input stays in your browser. FreeFormatter's tools posted what you entered to its server; BrowserUtils' formatters, converters and encoders run locally.
  • No third-party ads. FreeFormatter's tool pages carried multiple Google AdSense units each.
  • Tools FreeFormatter never had: JSON to TypeScript, Go and Java classes, a JWT decoder, JSON diff, and formatters for TypeScript, Python and Go.
