Discourse’s embedding system lets you show topic comments on external sites via an iframe — but until now, the experience was read-only. Visitors had to click through to your Discourse site to reply, like, or interact with the discussion.
We’ve added full app mode for embeds, which loads the complete Discourse application inside the iframe. Your visitors can reply, like, quote, and interact with topics without ever leaving your blog or website.
How to enable it
Navigate to Admin > Advanced > Embedding, and you’ll see a new toggle at the top of the page to enable full app mode.
When toggled on:
- The embed configuration snippet automatically includes the
fullApp: trueandembedHeight: '800px'parameters - The site setting to enable this mode is automatically enabled
The setting is also available under the Embedding > Settings tab as embed_full_app.
What changes for visitors
With full app mode enabled, the embedded iframe loads the full Discourse UI instead of a static list of replies. Visitors on your external site can:
- Reply to the topic directly
- Like and quote posts
- Navigate within the topic as they would on your forum
This gives your blog readers a first-class discussion experience without leaving the page.
