Publish Extensions

Whether you're a seasoned Magento 2 developer or just starting to explore extension development, one question often pops up: How much does it cost to publish on the Magento Marketplace? The answer might surprise you—it’s completely free. But just because it’s free doesn’t mean the process is simple or that quality can be overlooked.

In this post, I’ll break down what it really takes to publish a Magento 2 extension, why the Marketplace is worth your time (especially for paid products), and a few do’s and don’ts that will help your submission sail through Adobe’s review process. Let’s dive in.

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).

🔍 Testing Is a Must

No matter the price tag, Magento expects quality. Prepare comprehensive tests for every release—this boosts your credibility and reduces support issues.

✅ Do’s for a Successful Extension

  • Improve functionality and user experience

  • Include full testing with edge cases

  • Ensure compatibility with the latest Magento version

  • Fix reported bugs quickly

  • Provide clear documentation or a user guide

❌ Don’ts to Avoid

  • Don’t spam the Marketplace with low-value features

  • Don’t compromise site security with unsafe code

  • Don’t copy-paste other people’s work—build your own

  • Don’t cut corners—shortcuts today become bugs tomorrow
