Automatic height

ResizeObserver + validated messages

Frame-safe delivery

Only explicit embed mode can frame

Fixed iframe when scripts are blocked

Data-minimal SDK

Quick start

Responsive by default.

Paste the iframe and one versioned script. The iframe starts with a safe fallback height and updates as the tool opens panels, shows results, or changes layout.

The host SDK validates both the iframe origin and message source.

Multiple FixTools embeds can coexist on one page.

Dynamically inserted iframes are discovered automatically.

Ready, resize, completion, and error events use a bounded public protocol.

Embed SDK questions

Does the embed require an API key?

No API credential is placed in the snippet. The embedded tool keeps the access rules and practical limits of its full FixTools page.

Will a FixTools embed resize automatically?

Yes. The recommended v1 SDK validates messages from the FixTools iframe and adjusts its height as the tool changes. A fixed-height iframe remains available for platforms that do not run external scripts.

Where does file or text processing happen?

It depends on the selected tool. Some tools run entirely in the browser; others use a FixTools server or configured provider. Review the processing and privacy details on the individual tool before placing it in a sensitive workflow.

Can I use embeds in WordPress, Ghost, Notion, or Docusaurus?

WordPress, Ghost, normal HTML, and Docusaurus can use the responsive SDK snippet when custom code is allowed. Notion accepts the iframe URL but controls sizing itself, so the customizer provides a fixed fallback.

What data does the responsive SDK collect?

The SDK makes no analytics or advertising requests. It receives only bounded lifecycle metadata such as ready state, iframe height, tool path, and allowlisted completion status. It does not receive files, tool inputs, outputs, raw queries, or user identity.

Can I remove FixTools attribution or use custom branding?

Standard embeds require FixTools ownership and follow the tool’s existing access rules. Custom or white-label deployments are reviewed separately because branding, limits, support, privacy, and infrastructure requirements vary by product.
