Build Better Shopify Apps with the Right Tools

Save time and reduce errors with trusted development resources.

Let’s Get Started

Why Tools Are Crucial for Shopify App Developers?

Shopify apps extend store functionality, but developers face challenges like:

• Managing API authentication and billing
• Debugging webhooks and API calls
• Designing user interfaces that match Shopify’s admin
• Publishing apps that meet review standards

That’s where tools for Shopify app developers come in. They simplify workflows and help deliver high-quality apps faster.

Best Tools for Shopify App Developers

1. Shopify CLI

A must-have among the best tools for Shopify app developers, Shopify CLI helps create app projects, test extensions, and connect with your partner account.

• Create app boilerplates in minutes
• Test checkout UI extensions
• Preview theme changes live

💡 Why it’s useful: Saves setup time and reduces repetitive coding.

2. Shopify API Libraries

Shopify API libraries (Node.js, Python, Ruby) handle requests and authentication.

• Simplify REST and GraphQL calls
• Reduce coding errors
• Secure token handling

💡 Why it’s useful: Avoids writing raw API requests manually.

3. Polaris Design System

Polaris ensures your app looks native to Shopify. Merchants are used to Shopify’s admin design, so any app that looks different may feel complicated.

• Prebuilt React components
• Accessible, merchant-friendly design
• Consistency with Shopify Admin

💡 Why it’s useful: Merchants trust apps that feel like part of Shopify.

4. Ngrok (Free Tool)

If you’re looking for free tools for Shopify app developers, Ngrok is essential for webhook testing.

• Creates secure tunnels to local servers
• Let’s Shopify send data to your local machine
• Debug webhooks in real time

💡 Why it’s useful: Critical for testing before deploying.

5. GitHub & GitHub Actions

GitHub is where developers manage code, while GitHub Actions automates workflows.

• Version control and collaboration
• Automated testing and deployment
• Pull request reviews

💡 Why it’s useful: Keeps team projects organized and bug-free.

6. Postman (Free Tool)

Another entry under free tools for Shopify app developers, Postman, is perfect for API testing.

• Send test requests to APIs
• Debug responses
• Share collections with team members

💡 Why it’s useful: Confirms API logic before writing code.

7. Partner Dashboard

The Shopify Partner Dashboard is a hub for app management.

• Create and manage development stores
• Submit apps for review

Common Mistakes Developers Make With Shopify Tools

Even with the best tools for Shopify app developers, mistakes happen when they’re not used correctly. Avoid these pitfalls to save time and frustration:

1. Skipping Shopify CLI: Some developers still set up apps manually. This leads to inconsistent structures and wasted effort. Shopify CLI ensures your app follows current standards.
2. Ignoring Polaris Guidelines: Using Polaris components but not following spacing, typography, or accessibility rules makes the app look inconsistent. Merchants quickly notice when an app doesn’t “feel” like Shopify.
3. Testing Too Late: Waiting until the end of development to use Postman or Ngrok often exposes major issues late in the process. Test early and often to catch errors sooner.
4. Overusing API Calls: Shopify limits API requests. Developers who don’t batch calls or use GraphQL effectively risk hitting rate limits, leading to poor performance.
5. Not Automating Workflows: Skipping GitHub Actions or similar CI/CD setups causes repetitive manual testing. Automation saves time and keeps the codebase stable.
6. Underutilizing Partner Dashboard: Some developers treat the Partner Dashboard only as a publishing tool. In reality, it can be used for testing apps in different store environments, tracking installs, and monitoring revenue trends.

💡 Pro Tip: Always combine tools with Shopify’s official guidelines.
