The True Cost of Expo App Development A Comprehensive Guide logo

In the world of mobile app development, efficiency and reach are paramount. Business leaders and product managers constantly seek tools that can accelerate development cycles without sacrificing quality or user experience. This is where Expo has emerged as a game-changing platform. It enables development teams to build high-quality, universal applications for Android, iOS, and the web from a single codebase. While the promise of “write once, run anywhere” is compelling, understanding the true cost associated with leveraging this technology is crucial for effective project planning and budgeting.

This comprehensive guide will demystify the costs of using Expo. We will go beyond the sticker price of subscription plans to explore every facet of financial investment, including the nuanced usage-based fees, the complexities of integration, the cost of hiring skilled developers, and the long-term maintenance expenses you can expect. By the end, you will have a clear, holistic view of what it takes to build, launch, and scale a successful application with Expo.

An Introduction to Expo

Before diving into the financials, it’s important to clarify what Expo is. While sometimes mistaken for a programming language, Expo is an open-source platform built on top of React Native. It provides a suite of tools, services, and libraries that simplify the development of universal apps. At its core, Expo allows developers to write an application using JavaScript and React, and then deploy it as a native app on Android and iOS, as well as a progressive web app (PWA) on the web, all from a single, unified codebase.

The primary advantage is a dramatic increase in development speed. Instead of maintaining separate teams and codebases for each platform, a single team can build and iterate on one. The Expo SDK provides access to a wide range of device capabilities like the camera, file system, and push notifications, abstracting away much of the underlying native code complexity. A developer can create an app with a sophisticated layout, such as a two-screen bottom tabs interface using Expo Router, and integrate native system UI elements for tasks like selecting an image from the media library, all while working within the familiar React ecosystem.

However, this power and convenience come with a learning curve and a set of architectural considerations. Successfully building a seamless experience across three distinct platforms requires careful planning, especially when handling platform-specific differences and integrating third-party libraries. This is the landscape in which understanding the full cost becomes essential.

How Much Does It Cost to Use Expo?

The direct cost of using Expo is structured around a freemium model with several paid tiers designed to scale with your application’s needs. The pricing is a combination of a fixed monthly subscription fee and variable, usage-based pricing for services like builds, updates, and hosting. Let’s break down the plans and the associated costs.

Expo’s Subscription Plans

Expo offers four main plans, each catering to a different stage of a product’s lifecycle, from individual hobbyists to large-scale enterprise operations.

FeatureFreeStarterProductionEnterprise
Monthly PriceFree$19/month$99/month$1999/month
Additional UsageN/AYesYesYes
Builds30/month (max 15 iOS)$30 build credit$100 build credit$1000 build credit
Build Concurrency1125
Updates (MAUs)1,0003,00050,0001,000,000
Update Bandwidth100 GiB100 GiB1 TiB10 TiB
Update Storage20 GiB20 GiB1 TiB10 TiB

As you can see, the Free plan is quite generous, making it an excellent choice for personal projects, learning, and prototyping. It allows for a limited number of builds and updates, which is perfect for getting an app off the ground.

The Starter plan, at $19/month plus usage, is aimed at small teams and early-stage startups. It introduces build credits and a higher MAU limit for updates, providing the necessary resources to launch an app and begin acquiring users.

The Production plan costs $99/month plus usage and is designed for established applications with a growing user base. It offers significantly more build credit, a much larger MAU allowance, increased build concurrency to speed up CI/CD pipelines, and priority support.

Finally, the Enterprise plan at $1999/month is for large organizations that require extensive resources, the highest level of support, and predictable scaling.

Understanding Usage-Based Pricing

The phrase ”+ additional usage” is where the bulk of the cost variability lies. It’s crucial to understand these metrics to forecast your monthly expenses accurately.

Build Usage Pricing

After you exhaust the monthly builds on the Free plan or the included credits on a paid plan, you are charged per build. The cost depends on the operating system and the size of the “worker” (the virtual machine performing the build).

Worker TypePrice per Build
Android medium$1
Android large$2
iOS medium$2
iOS large$4

Larger workers provide more CPU and memory, which can significantly speed up build times for complex applications. Additionally, on the Starter, Production, and Enterprise plans, you can purchase additional build concurrency for $50/concurrency per month, allowing you to run multiple builds simultaneously.

CI/CD and Testing Costs

For automated workflows, Expo offers Continuous Integration (CI) minutes. You can run update jobs, which push new JavaScript bundles to your users, and custom jobs for other CI/CD tasks. The Free plan includes 100 minutes of update jobs per month. On paid plans, this usage is more flexible.

The cost per minute varies by the CI worker’s OS and specifications:

CI Worker TypePrice per Minute
Linux medium$0.018
Linux medium (nested virtualization)$0.020
Linux large$0.035
Linux large (nested virtualization)$0.040
macOS medium$0.075
macOS large$0.150

Furthermore, if you use Maestro for end-to-end testing, each test job incurs a $0.05 base fee plus the cost of the CI minutes it consumes.

Monthly Active User (MAU) Overage Pricing

One of the most powerful features of Expo is “Updates,” which allows you to push over-the-air (OTA) updates to your app without going through the app store review process. This is ideal for shipping bug fixes and new JavaScript-based features quickly. The plans include a certain number of Monthly Active Users (MAUs) who can receive these updates. If you exceed this number, usage-based pricing applies.

Starter and Production Plan MAU Pricing:

MAU TierPrice per MAU
Next 197k (Starter) / 150k (Production)$0.005
Next 300k$0.00375
Next 500k$0.0034
Next 1M$0.003

Enterprise Plan MAU Pricing:

MAU TierPrice per MAU
Next 1M$0.003
Next 1M$0.0024
Next 3M$0.0022
Next 4M$0.0016

Bandwidth, Storage, and Hosting Costs

Beyond builds and users, there are costs associated with the infrastructure that supports your app.

  • Global Edge Bandwidth: For delivering updates. After the included amount, the cost is $0.10 per GiB on all paid plans.
  • Update Storage: For storing your update bundles. After the included amount, the cost is $0.05 per GiB on all paid plans.
  • Hosting: All plans include a generous free tier for hosting services (100,000 requests, 1M CPU-ms, 1 GB storage). Overage is billed as follows:
    • Requests: $2 per 1M requests
    • CPU-ms: $0.04 per 1M CPU-ms
    • Storage: $0.04 per GB

Note: All prices shown are in USD and do not include any applicable sales tax. All plans and usage are subject to Expo’s Acceptable Use policy.

What Goes Into Integrating Expo Into an App?

The process of building an app with Expo involves more than just writing code. It requires a thoughtful approach to project setup, architecture, and configuration to harness the platform’s full potential. The journey begins with creating a new Expo app, often using a template with TypeScript enabled for enhanced code quality and maintainability.

From there, development involves several key stages:

  1. Navigation and Layout: A core part of any app is its structure. Developers will implement navigation using tools like Expo Router to create intuitive user flows, such as a standard two-screen bottom tabs layout.
  2. UI Component Implementation: The app will be built using fundamental React Native components like <Modal> and <FlatList> to create interactive and dynamic interfaces.
  3. Accessing Native Features: The Expo SDK is used to bridge the gap to native device functionality. This includes configuring the status bar, creating a custom splash screen, and setting the app icon. A common task is using the platform’s native system UI to allow a user to select an image from their media library.
  4. Integrating Third-Party Libraries: No app is an island. Integration often involves adding third-party libraries for specific functionality, such as capturing a screenshot of the UI and saving it to the device’s disk.
  5. Handling Platform Differences: This is one of the most critical and challenging aspects of universal app development. While Expo smooths over many inconsistencies, developers must still write conditional logic and platform-specific code to account for differences in UI conventions, APIs, and user expectations between Android, iOS, and the web. Ensuring a polished, native feel on each platform requires expertise and rigorous testing.

The complexity lies not in any single one of these steps, but in orchestrating them all within a single codebase. A poorly architected Expo app can become difficult to maintain, with platform-specific code tangled throughout the project, leading to bugs and slow development. This is why having an experienced team is not just a luxury, but a necessity for building a robust and scalable product.

The Cost to Hire an Expo Development Team

The cost of the Expo platform itself is only one part of the total investment. The largest expense is typically the human capital required to design, build, and maintain the application. Given that there is a high demand for skilled Expo developers, finding and retaining the right talent is a significant challenge.

Finding Individual Developers

There are several avenues for sourcing individual Expo developers. You can explore specialized tech communities like GitHub, Stack Overflow, and the official Expo forums. Freelance websites are another popular option, where pre-screened developers often bid on projects.

For a more streamlined process, platforms like Lemon.io have emerged. They offer to connect companies with vetted Expo developers, often within 24-48 hours. These platforms handle the tedious tasks of hiring—vetting for soft and hard skills, managing contracts, payments, and reporting—and often provide a no-risk trial period to ensure the developer is a good fit for your team. This can be a fast and cost-effective way to find a contractor for a startup.

Understanding Long-Term Maintenance Costs

Launching your app is not the end of the journey; it’s the beginning. Ongoing maintenance is a critical and recurring cost that must be factored into your budget. With Expo, these costs are primarily driven by your app’s growth and usage.

Key Maintenance Cost Drivers

  • User Growth (MAU Costs): As your user base grows, you will likely exceed the MAU limits for OTA updates included in your plan. The tiered pricing for additional MAUs will become a regular part of your monthly bill.
  • CI/CD and Testing: Continuous development means continuously running jobs in your CI/CD pipeline. The costs for update jobs, custom jobs, and Maestro end-to-end tests will scale with your team’s development velocity.
  • Bandwidth and Storage: Every OTA update you push consumes bandwidth. As your app grows in complexity and user numbers, your bandwidth and storage needs will increase, potentially incurring overage fees of $0.10/GiB for bandwidth and $0.05/GiB for storage.
  • Hosting Usage: If your app relies on Expo’s hosting services, increased traffic will lead to higher costs for requests, CPU time, and storage beyond the generous free tier.
  • Support: The Production and Enterprise plans include priority support. For an even higher level of service, the Enterprise Support add-on is available, representing another potential maintenance cost.

These variable costs mean that your monthly Expo bill will fluctuate. A successful marketing campaign that doubles your user base will also increase your MAU and bandwidth costs. A period of rapid feature development will increase your build and CI minute consumption. Proactive monitoring and forecasting are essential for managing these expenses effectively.
