How Much Does It Cost to Publish Magento Extensions or Themes?
Spoiler: It’s FREE.
If you're a Magento developer wondering how much it costs to publish your extension or theme on the Magento Marketplace—the answer is zero. Yes, you read that right. You don’t have to pay anything to list your extension.
So why should you publish?
🔹 When to Publish on Marketplace
Paid Extensions: If you're selling your extension, the Marketplace is highly recommended. It gives you exposure, credibility, and an official channel for distribution. Pair it with smart SEO on LinkedIn to increase visibility among Magento developers.
Free Extensions: Even if your extension is free, it's still wise to publish on both GitHub (for open contribution) and the Marketplace (for discoverability).
