Embed a Free SQL Formatter on Your Website

If you run a developer blog, internal documentation site, technical course, or SQL training resource, embedding a SQL formatter on your own pages saves your readers from copy-pasting to a third-party site. The catch: most embeddable SQL formatters require an API key, charge per request, or include heavy branding.

Our SQL formatter is embeddable for free. One iframe snippet, no API key, no rate limits, no Backend setup. Works on WordPress, Webflow, Wix, Squarespace, plain HTML, GitHub Pages, and any other website that supports embeds. No signup required to embed.

Why Embed a SQL Formatter on Your Site

If you run any of these types of sites, an embedded SQL formatter adds value to your readers:

• Developer blogs and tutorials. Readers studying SQL examples can format their own queries inline without leaving your tutorial.
• Internal company documentation. Engineering wikis and runbooks often reference SQL queries. An embedded formatter lets readers clean up their own queries while reading docs.
• SQL training courses (Udemy, Teachable, Thinkific). Students working through exercises can format their attempts as they learn.
• Database vendor sites and product documentation. Help readers format queries for your database product.
• SaaS tools that include SQL features. If your product takes SQL input from users, give them a formatter for free as a value-add.
• Stack Overflow alternatives and Q&A sites. Answer-givers can clean up their SQL before posting.
• Bootcamp and university course sites. Students get a formatter built into their course materials.
• SQL interview prep sites. Practice candidates can format their answers before submission.

The embed adds genuine reader value with zero setup beyond pasting an iframe.

How to Embed the Formatter — One Snippet

The embed code is a single iframe that you paste into any HTML, Markdown, or rich-text editor that supports embeds:

<iframe src="https://wildandfreetools.com/developer-tools/sql-formatter/" width="100%" height="700" frameborder="0"></iframe>

That is the entire setup. The iframe loads the full SQL formatter into your page. Readers paste their SQL, click Format, and get the result without leaving your site.

Adjust the width and height to fit your layout:

• Full-width content area: width="100%" height="800"
• Sidebar widget: width="350" height="600"
• Mobile-friendly: width="100%" height="900" — taller because mobile stacks the input/output

That is it. No API key, no JavaScript SDK, no library import.

Platform-Specific Embed Instructions

WordPress: Switch to the "Custom HTML" block (or "Code" block in older themes), paste the iframe snippet, save the post. The formatter appears inline.

Webflow: Drag an "Embed" element onto your page, paste the iframe snippet into the code field, click Save and Close.

Wix: Add an "HTML iframe" element from the Add Elements panel, paste the iframe snippet, click Apply.

Squarespace: Add a "Code" block to your page, paste the iframe snippet. Squarespace will render it in the published view.

Ghost: Add an "HTML" card in the editor, paste the snippet, save. Ghost renders the iframe inline.

Notion (public pages): Notion does not support arbitrary HTML embeds, but you can use the Embed block with the formatter URL — Notion will render it as an iframe.

Plain HTML: Paste the snippet anywhere in your HTML body. No additional setup.

Markdown (with HTML support): Most modern Markdown processors (MDX, Hugo, Gatsby, Next.js) accept inline HTML. Paste the iframe snippet directly.

GitHub Pages / Jekyll: Same as plain HTML — paste the snippet in your post or page markdown.

GitBook / Confluence / Notion: Use the iframe or embed block.

No API Key, No Rate Limits, No Backend Required

Many embeddable developer tools require an API key (you sign up, get a key, paste it into the embed snippet) and have rate limits (1000 requests per day on the free tier). Our formatter has neither.

Why no API key? The formatter runs entirely in the user's browser. There is no server-side API call. No request to count. No rate limit to enforce.

Why no backend? The formatting library is bundled into the page itself. When a reader pastes their SQL and clicks Format, the formatting happens in their browser using JavaScript. We do not need a backend.

This means:

• Embed it on a page that gets 1 million views per day — works fine.
• Embed it on 10,000 different sites — works fine.
• Use it commercially without licensing — fine.
• Use it in internal company tools without contracts — fine.

The only requirement: keep the iframe pointing to our domain so readers can access the formatter.

Reader Privacy Is Preserved

When a reader uses the embedded formatter, their SQL stays in their browser. The iframe loads our formatter page, which runs the formatting library locally. No SQL is sent to our servers.

This matters for these reader types:

• Enterprise readers who format production queries with sensitive table names.
• Healthcare developers (HIPAA-sensitive contexts).
• Financial services developers (PCI and SOX-sensitive contexts).
• Government developers (classified or restricted data).

You can confidently embed the formatter on your site without worrying about your readers leaking their data through it. Their SQL never leaves their browser, even when they use the embedded version on your page.

Other Browser Tools You Can Embed

The same embed approach works for many other tools on this site. If you build a developer-focused site, these are worth embedding alongside the SQL formatter:

JSON formatter — embed for users to format JSON inline. JSON Formatter.

Code formatter — JavaScript, HTML, CSS, GraphQL formatting. Code Formatter.

Regex tester — for blog posts about regex patterns. Regex Tester.

Code diff checker — for tutorials comparing two code snippets. Code Diff Tool.

Each uses the same iframe embed pattern. No API key, no rate limits, no backend.

Frequently Asked Questions

Is the embed really free with no API key?

Yes. Paste the iframe snippet, the formatter loads. No API key, no signup, no rate limits. Free for unlimited embeds.

Will my readers SQL be uploaded to your servers?

No. The formatter runs entirely in the reader browser, even when embedded on your site. Your readers SQL never leaves their device.

Can I embed this on a commercial site?

Yes. The embed is free for personal, commercial, internal, and educational use. No licensing required.

Will the embed break if you change the URL?

We try to keep stable URLs. If we ever need to change the formatter URL, we will set up a redirect from the old URL to the new one so existing embeds continue to work.

Can I customize the look of the embedded formatter?

Limited customization through iframe sizing (width and height). Visual styling matches the wildandfreetools.com dark theme. For full custom styling, you would need to host your own formatter using the open-source sql-formatter library.
