Embeddable tools

Publisher integration · 1,000+ tools · no signup · no API key

Build the embed before you paste it.

Pick any executable tool in the canonical catalog, size it for your layout, preview the real iframe, copy the integration format your CMS accepts, then locally verify the HTML that actually survived the CMS save step.

Live sizing controls

Set max width, starting height and auto-resize before copying code.

Four integration formats

HTML + auto-resize, no-script HTML, React and Markdown fallback.

Verify after CMS save

Paste the saved block back into the local checker to catch stripped attributes, attribution or resize guards.

Visible Solarc Labs attribution is part of the embed exchange. Attribution clicks carry tool-level referral tags so distribution can be measured. The no-script version stays usable with fixed height when a CMS strips inline scripts. Markdown is a fallback canonical link rather than an interactive iframe.

Optional · publisher-owned measurement

Count embed reach without sending tool answers to Solarc Labs.

Embeds emit only two lifecycle signals to their parent page: ready when the iframe runtime mounts and interaction once, on the visitor's first interaction with the working tool. The message contains only the public tool slug and event name — never inputs, results, files, email addresses or other answer data.

ready

A browser-native embed runtime mounted in the publisher page. Useful as a privacy-safe reach/load signal.

interaction

The first pointer, input, change or keyboard interaction inside the tool. Emitted at most once per iframe lifetime.

<script>(function(){var O="https://solarclabs.com";window.addEventListener("message",function(e){if(e.origin!==O||!e.data||e.data.type!=="solarc-free-tool-event")return;var k=e.data.event,s=e.data.slug;if((k!=="ready"&&k!=="interaction")||typeof s!=="string")return;var frames=document.querySelectorAll('iframe[src^="'+O+'/free-tools/embed/"]'),ok=false;for(var i=0;i<frames.length;i++){var f=frames[i];if(e.source!==f.contentWindow)continue;try{var u=new URL(f.src);if(u.origin===O&&u.pathname==="/free-tools/embed/"+s)ok=true}catch(_){}}if(!ok)return;window.dispatchEvent(new CustomEvent("solarc-free-tool-event",{detail:{slug:s,event:k}}));});})();</script>

The bridge validates the exact Solarc Labs origin, matches the source window to a Solarc Labs embed iframe, checks the slug against that iframe URL and then dispatches a local solarc-free-tool-event CustomEvent. It makes no network request. Connect that local event to your own analytics only if your site's consent and privacy rules allow it.

Install verifier · browser-local

Check what your CMS actually saved.

Paste the final HTML block after WordPress, Webflow, a knowledge base or another CMS has saved it. The verifier parses the pasted text in this browser and checks the Solarc iframe contract. It does not fetch your website or send the snippet anywhere.

This checks embed markup, not your whole website, CSP, consent setup or browser-extension behavior. A passing report is not a security or accessibility certification.
