Features

This plugin lets you override your Open Graph, Twitter, title, and description tags.

Configuration

This plugin ships with only one setting: Open graph overrides, which opens to this modal:

You have a URL property, which will match and use it to override your meta tags – this will be your ID.

Title - Will override the title, og:title, and twitter:title tags. If empty, it will default to the original value.

Description- Will override the description, og:description, and twitter:description tags. If empty, it will default to the original value.

Settings

Include a table of settings and setting descriptions

I’m really excited this exists. The thought I just had tho was: does this work for topics?

I assume no, because then one might have to manually type in open graph info for each topic.

Then I thought: what if the topic description were autogenerated by Discourse AI summarizing the topic?

Maybe using Discourse AI Topic Summary 🤖

The title could be the same and description the AI summary. And maybe tweakable if people want to edit it, similar to on Wordpress with Yoast.

Any thoughts on this?

I think it does! But it would be necessary to add an override for every topic.

Maybe this could be a feature for AI Topic Summary–it could override the metadata content based if they had the ai summary in the topic itself.

Some pseudo-code, inspired by this snippet in the Open Graph plugin:

  register_modifier(:meta_data_content) do |content, property, opts|
    next content if property == :url # we don't want to override the url
    url = opts[:url]
    override = Topic.find_by_url(url)[:ai_meta_data_override]
    if override
      content = override[property] if override[property] # it can be either :title or :description
    end
    content
  end

There doesn’t need to be any AI built in here – all you need for dynamic OG images is to be able to pass parameters from the topic into the URL like ?title=Hello+World&date=2025-04-27

This could be a template system like {{topic.author.username}} or whatever you think makes sense here

That will let the user plug into any existing service that generates OG images, or connect to one of their own, or to a future offering by Discourse if you want first class support

As someone who is fairly new to Discourse; cant this already be done in the Discourse settings?

With this precision(regexing) no.

And eventually we could add images dinamically

Oh ok would you mind giving me a use case when you would like to override the settings? Is it when you are sharing a link from your forum, for example a topic that it will then look different or mainly for SEO concerns?

Sure! One very good example is the category list page:

We can override both title and description to be more descriptive

Or for very specific topics that you want to have a different text when sharing in social media:

We could change to be just the title and some kind of small description

That is very cool. I know some companies have some impressive dynamically added images to open graph to make it more enticing. I hope this feature gets added to Discourse core or as a standard plugin. Great work!
