Who Should Maintain Your MVP After Launch: Freelancer, In-House or Retainer?

The short answer

Whichever you pick, put in writing who is responsible for the app after launch.

• App is stable, few changes planned, you can manage tasks yourself — freelancer, paid per task.
• App is the core of your business, you ship every week, you have funding for a full-time hire — in-house developer.
• You need fixes, updates and some new features, without hiring or managing a developer — monthly retainer with an agency.
• You're not sure yet — retainer for the first months after launch, then reassess.

What maintenance actually involves

Before you compare options, know what you're hiring for. Post-launch work on a mobile MVP usually falls into five areas. Whoever you pick has to cover all five, or you need to know who covers the gaps.

• Bug fixes. Real users find problems your testing missed: old phones, weak connections, flows nobody pictured.
• OS and store updates. Apple ships a major iOS version every autumn. Google Play requires apps to target a recent Android API level before you can publish updates.
• Security and dependencies. Libraries get patched. Outdated ones become a risk.
• Release management. Building, testing and submitting updates through TestFlight and Play Console.
• New features. Version 1.1 and onward, driven by user feedback.

Option 1: a freelancer

A freelancer works on your app when you send them a task. You pay per task or per hour. Choose a freelancer if your app is stable, changes are rare, and you're comfortable reviewing technical work.

• Covers well: one-off bug fixes and small changes; occasional updates when you have a clear list.
• Gets risky: availability — a good freelancer is busy with other clients, so an urgent crash may have to wait.
• Continuity: if they leave, what they know about your codebase leaves with them.
• Management: you write the tasks, check the work and set priorities. That's hard if you're not technical.

Option 2: an in-house developer

You hire a developer onto your team, full time or part time. Choose in-house if the app is your business, you have funding, and you ship changes every week. Many founders make this move after they find product-market fit, not before.

• Covers well: daily product work and fast iteration; deep knowledge of your code and your users; full alignment with your priorities.
• Gets risky: cost and commitment — you pay salary, benefits and recruiting time before any code ships.
• Single point of failure: with one developer, one person knows everything. Holidays and resignations hurt.
• Hiring blind: if you're not technical, it's hard to judge a developer's level in an interview.

Option 3: a monthly retainer

You pay an agency a monthly fee for a set amount of work. Usually it's the team that built the app. Choose a retainer if you need steady upkeep and some feature work, but not a full-time hire.

• Covers well: fixes, updates, security patches and releases, handled without you managing a developer.
• Continuity, because the team already knows the code.
• Flexibility, if hours can go up or down each month.
• Gets risky: lock-in if the contract has a long minimum term or you don't own the code; unused hours if the plan doesn't adjust to quiet months; vague scope if the contract doesn't say what's included.

What each option covers

Use this as a comparison, not a quote.

• Urgent bug fixes — freelancer: depends on availability; in-house: yes; retainer: depends on contract terms.
• Yearly iOS and Android updates — freelancer: only if you ask; in-house: yes; retainer: usually included.
• Security and dependency updates — freelancer: only if you ask; in-house: yes; retainer: usually included.
• Release management — freelancer: sometimes; in-house: yes; retainer: usually included.
• New features — freelancer: per task; in-house: yes; retainer: within monthly hours.
• Who manages the work — freelancer: you; in-house: you or a tech lead; retainer: the agency.
• Risk if one person leaves — freelancer: high; in-house: high with one developer; retainer: lower, it's a team.
• Commitment — freelancer: per task; in-house: employment contract; retainer: monthly, check the terms.

How to choose: 5 criteria

Answer these before you sign anyone.

• How often will the app change? Rare changes favour a freelancer. Weekly changes favour in-house or a retainer.
• Can you manage technical work? If not, avoid any setup where you write tickets and review code alone.
• How bad is downtime for you? If a crash costs you sales or users, you need a guaranteed response time, not “when I'm free”.
• What's your runway? A hire is a long commitment. A retainer you can cancel anytime isn't.
• Who knows the code today? If you move away from the team that built it, you pay someone new to learn it.

Questions to ask before you sign

Whatever you choose, get clear answers to these. If you're still comparing agencies to build the app in the first place, see the 12 questions before you sign.

• Do I own the code, the GitHub repo and every account? Hosting, store accounts and services should all be in your name.
• What's the response time for a critical bug? Ask for it in writing.
• Are iOS and Android version updates included? Or are they billed as extra work?
• What happens to unused hours? Do they roll over, or can you lower the plan?
• Is there a minimum term or notice period?
• Who will actually work on my app? One person or a team?
• Will I get handoff documentation? It lets you switch providers without starting over.
• Can you list every service my app uses? If they can't, they don't know your app well enough.

Set yourself up to switch at any time

Your best protection isn't which option you pick. It's being able to change your mind later. For the Apple side specifically, see our guide on iOS app maintenance cost after launch.

• Code in your GitHub, accounts in your name. No provider should hold your app hostage.
• One codebase for iOS and Android. Any developer you bring in maintains one project, not two.
• Crash reporting installed before launch. Whoever maintains the app sees issues right away.
• Written documentation at handoff. A new developer gets up to speed faster.

How Build MVP Fast handles it

We build your MVP at a fixed price, so you know the build cost before you start. The MVP launch package is $3,460, delivered in about 21 days, for iOS and Android from one codebase. It includes 2 weeks of post-launch bug fixes, handoff documentation, App Store and Google Play submission support, and full code ownership in your GitHub. After that, you choose. You can hand the code to a freelancer or your own hire, along with the documentation. Or you can keep us on with continuous support and maintenance from $500 per month. That covers bug fixes, crash monitoring, security patches, dependency updates, release management on TestFlight and Play Console, and ongoing feature work. You can cancel anytime and scale hours up or down each month.

Should the agency that built my MVP also maintain it?

It's often the simplest option, because they already know the code. Just make sure you own the repo and accounts, and that the contract lets you leave. That way you stay because you want to, not because you're stuck.

When should I hire an in-house developer?

Usually once the app is the centre of your business and you ship changes every week. Before that, a full-time hire is a big commitment for work that comes in waves.

Can a freelancer handle yearly iOS and Android updates?

Yes, if they're available when the update lands and you ask them to do it. The risk is that nobody plans for it. Put it on a calendar every autumn.

What happens if my freelancer disappears?

If the code is in your GitHub and every account is in your name, you hand the repo and documentation to someone new. They'll need time to learn the codebase before they can fix things quickly. If the code or accounts sit with the freelancer, getting them back can be slow and sometimes impossible. Check who owns what before you hand over the app.
