Solo developer, agency or offshore: an honest comparison

You need software built and you're not sure who to hire. A freelancer, an agency in Cape Town and a remote team overseas all sent back quotes, and the numbers are nowhere near each other for what looks like the same job. That isn't simply "you get what you pay for". Each option has real strengths and real risks, and the right one depends on the size of the job, how involved you want to be, and what happens after launch. I am a solo developer, so I will be honest about my bias upfront. I also work with agencies, often on the complex parts of their clients' projects, and I've taken over work started by remote teams. Here is what I've seen.

Option 1: A Solo Developer

A solo developer is one person who handles architecture, development, and delivery directly. No project manager in between. No account manager. You talk to the person who writes the code.

Advantages:

• Direct communication. No telephone game. When you explain what you need, the person who builds it hears it directly.
• Lower overhead. No office rent, no sales team, no management layer.
• Consistency. The same person works on your project from start to finish. They understand the context, the decisions, and the tradeoffs.
• Accountability. There is one person responsible. No finger-pointing between departments.

Risks:

• Capacity. One person can only work on so many things simultaneously. If your project is genuinely large (a full enterprise platform with a hard deadline), one person may not have the bandwidth.
• Availability. If the developer gets sick, goes on leave, or takes on too much work, your project slows down. There is no bench to pull from.
• Bus factor. If the relationship ends, you need to find someone new who can understand the code. This is mitigated by clean code, documentation, and version control, but it is still a risk. Every project ships with a handover pack, and ownership is agreed in writing before work starts.
• No built-in QA or design. You may need to source testing and design separately.

Best for: Small to medium projects. Projects where direct communication matters. Ongoing development relationships. Businesses that value a personal working relationship.

Option 2: An Agency

An agency is a team: project managers, designers, developers, QA engineers, account managers. You work with a company, not an individual.

Advantages:

• Team capacity. Multiple developers can work on your project simultaneously. Large projects can be delivered faster.
• Multiple skill sets. Design, development, testing, and project management under one roof.
• Process. Formal workflows, sprint planning, status reports, dedicated project management.
• Continuity. If one developer leaves the agency, others can continue the work.

Trade-offs:

• More people between you and the code. You talk to the account manager, who talks to the project manager, who talks to the developer, so messages can shift along the way.
• A higher overall cost, because you're paying for a team, not one person.

I work with agencies often. They bring me in for the complex builds, integrations and custom work, and that partnership works because each side does what it's best at.

Best for: Large projects with hard deadlines. Projects that need dedicated design and QA. Companies that want formal process and regular reporting. Projects where team capacity matters more than individual expertise.

Option 3: A Remote Team in Another Country

Hiring a remote team means working with developers based somewhere else, often with a large available talent pool.

Advantages:

• Large talent pools. Easier to find developers with specific technology experience at scale.
• Availability. Time zone differences can mean work happens while you sleep, if managed well.

Risks that apply to any remote hire:

• Quality varies enormously. The developer who did the test project may not be the one assigned to your work.
• Turnover. The person who understood your project six months ago may be gone, replaced by someone starting from scratch.
• Contracts across jurisdictions are harder to enforce, and data sovereignty matters if the team is handling South African customer data (POPIA compliance).

Best for: Well-defined, commodity development tasks. Projects where you have a technical lead in-house who can specify requirements precisely and review code regularly.

How to Decide

Ask yourself these questions.

How complex is the project? Simple, well-defined projects can be outsourced. Complex projects with ambiguous requirements need direct communication, which favors a solo developer or local agency.

How involved can you be? Remote teams and large agencies need detailed specifications upfront. Solo developers and small teams can work more collaboratively, figuring things out together. If you want to iterate and evolve the product, you need tight communication loops.

What matters most to you? If you want the best quality-to-cost ratio with minimal management overhead, a solo developer is usually the most efficient. If you need scale and dedicated design and QA, an agency provides it. If the work is well-defined and you have in-house technical oversight, a remote team can work.

What happens after launch? The project is not done when it launches. Who maintains it? Who fixes bugs? Who adds features? A solo developer you have a relationship with is easy to call. An agency that assigned your project to a team that no longer exists is harder. A remote team you have never met in person may or may not be available in six months.

Do you need design? Solo developers typically do not do visual design. If your project needs significant design work, you either hire a designer separately or go with an agency that has one in-house.

Red Flags for Any Option

No portfolio of similar work. They can build anything, but they cannot show you something they have actually built. Avoid.

No written scope before starting. If they start work before defining what "done" means, you will pay for ambiguity.

No written scope tied to the payments. How much you pay up front matters less than what each payment buys. Every payment should be tied to a written, defined piece of work. This is how I do it: you pay per piece of work, the written plan, then each working piece, on the terms written in its quote. There's no single bill for the whole project up front, and you're never committed to more than one piece.

No version control. If the code is not in Git (or equivalent), there is no history, no backup, and no way for another developer to continue the work.

Reluctance to introduce you to past clients. Reviews on a platform are useful. But a developer who can connect you directly with a client who will vouch for them is showing real confidence.

Choosing With Confidence

Solo developers offer direct communication and consistency for small to medium projects. Agencies offer scale and process for larger projects. Remote teams can offer well-priced capacity for well-defined work.

The best choice depends on your project complexity, your involvement, and your post-launch needs. There is no universally correct answer, but there are warning signs that apply regardless of which option you choose.

If you are evaluating options and want to understand whether a solo developer is the right fit for your project, tell me the problem.

You can also see an example of a large-scale project I delivered as a solo developer: a custom POS system built alone in 13 months for 7 branches processing 5,000 transactions a day.
