Browse the tools directory and open a supported tool page (e.g. JSON Formatter).
Scroll below the tool — you'll find a collapsible "Embed this tool" section. Adjust the width and height to match your layout.
Click "Copy" and paste the iframe code anywhere in your HTML, Markdown, or CMS.
The embed includes a small "Powered by DevFlow" link in the footer. Please keep it intact — it helps us continue offering these tools for free.
<iframe src="https://wtool.dev/embed/json-formatter" width="800" height="500" style="border:none;border-radius:8px;overflow:hidden;" title="JSON Formatter — Powered by DevFlow" loading="lazy" allowtransparency="true" ></iframe>
All DevFlow embeds include a small "Powered by DevFlow · wtool.dev" link in the footer of the widget. This attribution must remain visible and must not be hidden or obscured. Removal of the attribution is a violation of the embed terms and may result in your access being blocked.
The attribution link is a dofollow link to the canonical tool page on wtool.dev. This is by design — it allows DevFlow to provide these tools for free in exchange for a small SEO benefit.
