iOS Sideloading 2026: What the DMA Actually Changed and Why the App Store Is Still the Default

The EU Digital Markets Act (DMA) cracked open iOS distribution. Apple now allows alternative app marketplaces, third-party payment processing, and non-WebKit browser engines in the EU. But in 2026, the App Store still dominates. The reason is not technical. It is economic and regulatory.

The DMA did not create a free-for-all. It created a new, negotiated terrain with fees, entitlements, notarization, and ongoing compliance scrutiny. That is why the question is no longer "Can you distribute outside the App Store?" It is "Does it make sense to?"

This article breaks down what actually changed, what it costs, and how developers should think about EU distribution in 2026.

The DMA clock: when the obligations kicked in

The DMA obligations for designated gatekeepers became enforceable in March 2024. From that point, Apple had to prove compliance and submit formal compliance reports, with the Commission assessing whether the measures meet the law's goals.

That timeline matters because it explains Apple's speed in rolling out iOS 17.4 features and why the Commission continues to evaluate the new business terms.

What Apple shipped to comply

In January 2024, Apple announced changes to iOS, Safari, and the App Store in the EU. The changes included:

• Alternative app marketplaces and new APIs to distribute apps outside the App Store
• New frameworks for alternative browser engines
• New options for using third-party payment providers and link-outs for digital goods

Those capabilities rolled out in iOS 17.4 to EU users. On paper, that is the DMA baseline: more choice, more distribution paths, more payment options.

How alternative app marketplaces actually work

Apple's developer support documentation shows the real mechanics:

• Marketplace apps must be notarized and approved through a dedicated entitlement.
• The marketplace app is installed from the marketplace developer's website, not the App Store.
• Marketplace developers must meet security and operational requirements, including anti-fraud, refunds, and moderation.

This is not frictionless sideloading. It is a new distribution regime with approvals, obligations, and platform-level guardrails.

The Core Technology Fee is the real hinge

The Core Technology Fee (CTF) is the part of the business terms that changes the economics.

Apple's terms allow one million free first annual installs per year. After that, developers pay a CTF of EUR 0.50 for each additional first annual install.

That number forces a new math. It is not catastrophic for every developer, but it changes the threshold at which alternative distribution makes sense.

What the fee looks like in practice

These examples use Apple's stated EUR 0.50 per install after the first million:

First annual installs (EU)	CTF cost above 1M
2 million	EUR 500,000
5 million	EUR 2,000,000
20 million	EUR 9,500,000

This is why many large apps still hesitate to move outside the App Store. The fee is not simply a toll. It is a new business model.

Why the Commission is still investigating Apple

In June 2024, the European Commission issued preliminary findings that Apple's App Store steering rules were in breach of the DMA and opened a separate non-compliance investigation into Apple's new contractual terms, including the Core Technology Fee.

That matters in 2026 because the rules are still evolving. The Commission is not just checking if alternatives exist. It is assessing whether the terms make competition viable.

The 2026 reality: openness with constraints

The EU forced Apple to open the doors, but Apple still controls the architecture. That produces a specific reality:

• Yes, alternative marketplaces exist. But they require entitlements, notarization, and operational commitments.
• Yes, payment alternatives are permitted. But steering rules and fees are under active scrutiny.
• Yes, browser engines can change. But real adoption depends on performance, security, and user habits.

In short: openness exists, but it is bounded by compliance costs and platform rules.

What developers should do now

1. Model your install economics

If you are likely to exceed one million first annual installs in the EU, model the CTF impact and compare it to App Store fees. The right answer depends on your revenue per user, margins, and update cadence.

2. Treat alternative distribution as a product

An alternative marketplace is not just a channel. It is a user experience, a trust layer, and a support system. If you cannot deliver refunds, account recovery, and anti-fraud operations, it will not scale.

3. Separate EU strategy from global strategy

The DMA is EU-only. A strategy that makes sense in Europe may be harmful elsewhere. Keep distribution logic region-specific.

4. Expect policy change

The Commission is still investigating. That means fees, steering rules, and approval processes could evolve. Build with flexibility, not assumptions.

The bigger shift

The DMA changed the rules. It did not end Apple's influence. In 2026, the App Store is still the default because it remains the lowest-friction option for users and developers, even with new choices.

The real story is not that iOS opened. It is that iOS became negotiable. Distribution is now a strategy, not a checkbox. The developers who win are the ones who understand the economics, build trust outside the App Store, and treat compliance as a competitive edge rather than a burden.
