Generate Open Graph Images in GitHub Actions Without a Browser

If you've ever shared a link to your website in a messenger or social network, you know how important the preview image is. It attracts attention, increases click-through, and makes your content look professional. But what if you don't have a designer or time for manual image generation? The solution is automation with GitHub Actions.

What Are Open Graph Images and Why You Need Them

Open Graph (OG) is a protocol that lets you set a title, description, and image for link previews. When you send a link in Telegram, Slack, or Twitter, the OG image determines how your post looks. Without it, the link looks gray and uninteresting.

For online services, especially payment and fintech projects, quality previews are critical: they form the first impression of the brand. Imagine sending a client a link to a payment page or an article about virtual cards — and seeing a dull square with text. Not a great way to build trust.

How to Automate OG Image Generation with GitHub Actions

GitHub Actions is a built-in CI/CD system that lets you automate any task, including image generation. Usually, it involves Puppeteer or Playwright, but they require installing a browser, which slows down builds and increases costs.

The new approach, described in the article, allows generating OG images without a browser. This means you can create previews for each new blog post, release notes, or PR previews right in the build process. Everything happens in one step, quickly and cheaply.

Practical Benefits for Developers

• Time savings: no need to manually create images in Photoshop.
• Consistency: all images will be in a unified style if you set a template.
• Automation: images are generated automatically with each content update.
• No browser: fewer dependencies, faster builds.

How This Relates to Virtual Cards and Online Payments

At first glance, what does this have to do with virtual cards? Actually, it's simple: if you develop a service that accepts payments, you want your pages to look presentable. For example, a page describing pricing or an instruction on how to pay. A beautiful OG image increases trust and conversion.

Moreover, automating image generation is an example of how to optimize routine processes. Similarly, you can automate checking card limits, setting up 3DS, or handling declines. Anything that can be automated, should be automated.

Conclusion

Generating OG images in GitHub Actions is a handy tool for developers who want to improve the look of their links without extra costs. This is especially relevant for fintech projects, where trust and professionalism play a key role. Try implementing this approach in your project — and you'll see how easy it is to make content more attractive.
