Five modules on demand.

Add feedback, voting, your roadmap, release notes and surveys to any website. The launcher is tiny and isolated; the full interface loads in a sandboxed iframe only when needed.

Feedback

Install

Paste. Done.

Paste before the closing </body> tag. The workspace key is public by design — it cannot read private data or perform staff actions.

<script
  async
  src="https://ext0.com/sdk/v1/feedback-widget.min.js"
  data-workspace="pub_YOUR_PUBLIC_WORKSPACE_KEY"
></script>

Use your own buttons

Hide the floating launcher and open any tab programmatically.

<script async src="https://ext0.com/sdk/v1/feedback-widget.min.js"
  data-workspace="pub_YOUR_PUBLIC_WORKSPACE_KEY"
  data-launcher="false"></script>

<button type="button" onclick="window.FeedbackWidget.open('feedback')">
  Suggest a feature
</button>
<button type="button" onclick="window.FeedbackWidget.open('roadmap')">
  View roadmap
</button>

Attributes

Five knobs. Sensible defaults.

Attribute	Values	Purpose
`data-workspace`	pub_…	Your public workspace key (required)
`data-launcher`	true \| false	Show the floating launcher button
`data-theme`	light \| dark \| auto	Initial appearance
`data-position`	right \| left	Launcher placement
`data-tab`	feedback \| roadmap \| changelog \| surveys	Default tab when opened

Colors, tabs, greeting, launcher label/icon, offsets, z-index, survey prompts and allowed domains are managed in your dashboard — preview changes before saving.

SDK

Drive it from your own code.

Calls made before the script loads are queued and replayed. All methods live on window.FeedbackWidget.

Method	Behavior
`init({ publicKey, theme, position, launcher })`	Programmatic alternative to data attributes. Safe to call repeatedly.
`open(tab, options?)`	Open 'feedback', 'roadmap', 'changelog' or 'surveys'; optionally pass an item or survey id.
`close()`	Close the panel and restore focus to where it was.
`toggle(tab?)`	Toggle the panel open or closed.
`identify({ token })`	Pass a short-lived, server-signed identity token for your logged-in user.
`logout()`	Clear the identified session from widget memory.
`setTheme('light' \| 'dark' \| 'auto')`	Change the appearance at runtime.
`on(event, cb) / off(event, cb)`	Listen to ready, open, close, vote, submit and surveyComplete.
`destroy()`	Remove the launcher, iframe and all listeners.
`onReady(cb)`	Run a callback once the SDK has initialized.

Secure by design

Strict postMessage origin checks with a per-instance handshake, allowed-origin lists per workspace, and no reliance on third-party cookies.

Signed SSO

Identify logged-in users with a short-lived token signed by your server — never a secret in the browser.

Fast & isolated

Small async loader, Shadow DOM launcher, lazy iframe. Failures never block your page.
