Agency vs freelance to build a SaaS: the honest comparison

Agency too expensive, freelance unreliable, no-code too limited, AI tools that hit a wall... Here's the unfiltered comparison to choose how to build your SaaS.
TL;DR
- Agency: quality and structure, but a minimum of €40,000 to €100,000, with 3 to 6 months lead time.
- Classic freelance: cheaper, but real reliability and availability risk.
- No-code (Bubble, Framer, Webflow): great for prototyping and can even scale up to a point, but expect rising costs, no code ownership, and vendor lock-in.
- AI tools (v0, Cursor, Lovable, Bolt): excellent to ship an MVP for under €20 and get your first customers, but struggle to scale without a human keeping the codebase clean.
- What you actually want: speed + controlled budget + production-ready code. That's exactly what Startup Express offers: an MVP delivered in 10 days for €7,000, paid on delivery.
The non-technical founder's dilemma
You have an idea. It holds up. You might even have early users waiting.
The one thing missing: the product.
And that's where the real headache starts. You're not a developer. You've searched "how to build a SaaS" and found dozens of contradictory answers. Agency? Freelance? No-code? Build it yourself with AI?
Every option has its advocates. Every option also has its blind spots, which nobody mentions clearly.
Here's the honest comparison.
The 4 options side by side
| Agency | Freelance | No-code | AI tools | |
|---|---|---|---|---|
| Budget | €40,000 – €100,000 | €10,000 – €30,000 | €0 – €500/month | €0 – €50/month |
| MVP timeline | 3 to 6 months | 2 to 4 months | 2 to 6 weeks | 1 to 2 weeks |
| Code quality | High | Variable | N/A | Variable |
| Reliability | High | Risk | Platform risk | Risk |
| Multi-tenancy | Yes | Yes | Fragile | Fragile |
| You own the code | Yes | Yes | No | Yes |
The agency: when it makes sense (let's be honest)
An agency is a structured team: a project manager, a designer, two developers, a QA. Everyone works together, with a proven methodology.
The real advantages:
- Guaranteed continuity. If a developer leaves, the agency replaces them without you bearing the consequences.
- Proven process. You're buying a method, not just hours of code.
- Contractual accountability. The agency commits to a deliverable.
When to choose an agency:
- You've raised funding (Series A minimum) and need a flawless product.
- Your project is complex, with multiple integrations and strong regulatory constraints.
- You have €60,000 to €100,000 available and several months to spare.
The problem for an early-stage founder:
This isn't the situation most SaaS project owners are in. You're in validation mode. You haven't yet proven people will pay for your product. Committing €50,000 to an agency before you have a single paying customer is a huge risk.
And the timelines (3 to 6 months) mean your market window can close before you've even shipped.
The classic freelance: the real problem
On paper, the freelance is the ideal solution. Cheaper than an agency, more flexible, direct contact.
In practice, it's more complicated.
The availability problem. A good senior freelance is rarely available immediately. They have other clients. Your project comes after everyone else's emergencies.
The reliability problem. No structure behind them. If the freelance gets sick, switches projects, or disappears: your product stops. No guaranteed continuity.
The scope problem. A solo freelance can cover the whole stack, but they necessarily rely on external tools to make up the gap: BaaS like Supabase or Neon for the database, Vercel or Cloudflare for deployment and infrastructure. It works, but it creates a dependency on third-party providers. For a startup in validation mode, that's not a problem, it's actually an advantage (speed, lower cost). For a more mature company that wants to internalize and control its infrastructure, it's a constraint to anticipate.
The time problem. A project that takes 2 months with a team can take 4 to 6 months with a solo freelance, because they handle everything sequentially.
This isn't a criticism of freelancers. It's the structural reality of the model. Experience level matters, of course: a senior freelance with ten years of SaaS under their belt handles these problems far better than a junior. But the best profiles are also the least available, and the most expensive.
No-code and AI tools: how far do they actually go
No-code (Bubble, Framer, Webflow, WeWeb...)
No-code is excellent at one thing: validating an idea quickly at near-zero cost.
For a prototype, an investor demo, a market test: it's unbeatable. And contrary to what you sometimes read, it can even scale up to a point. Plenty of SaaS products run perfectly well on Bubble with thousands of users.
The real problems come from elsewhere.
Costs that balloon. No-code platforms often bill by usage (workload units on Bubble, bandwidth on Webflow, etc.). At the start, it's a few dozen euros a month. As you grow, the bill can quickly exceed what your own infrastructure would cost.
You don't own your code. Your business logic lives inside the platform's proprietary runtime. You can't migrate easily to something else. If Bubble doubles its prices tomorrow, or changes its policy, you absorb it.
Vendor lock-in. This is the corollary of the previous point. You depend on the platform, its product decisions, its outages, its roadmap. For a small structure in validation mode, that's acceptable. For a SaaS that aims to become a real business, it's a structural risk.
No-code isn't "for everyone". This is the most common misconception. A non-technical person can build basic things: a landing page, a form connected to Airtable, a simple directory. But the moment you need to build a real SaaS with workflows, conditional logic, API integrations, you have to get your hands dirty. It's not code, but it's a technical exercise that demands time, rigor, and learning.
AI tools (v0, Cursor, Lovable, Bolt)
These tools have changed the game. AI now generates quality code, entire projects that hold up, in minutes. It's improving fast, and what was impossible a year ago is now trivial.
So the real problem isn't technical in the strict sense. It's elsewhere.
The iteration wall. There's always a moment when AI gets stuck on a specific problem. No matter how you rephrase the prompt, add more context, refine your expectations: it doesn't get resolved. And with each new prompt, the AI tries a different approach, stacking another attempt on top of the previous one. Ten iterations later, you end up with Frankenstein code, patches layered everywhere, and the original bug still there.
Progressive degradation. AI relies on the rest of the codebase to generate what comes next. Without supervision, without sanity checks, without someone keeping the code clean, quality degrades mechanically as the project grows. Regressions pile up. Features that worked yesterday break today. Adding a feature becomes more and more costly.
The ceiling hits fast. As long as the project is small, everything's fine. Past a certain complexity threshold, without a human who understands the code stepping in, it becomes unmanageable.
None of that takes away from how powerful these tools are. To build an MVP for under €20, validate an idea, land your first customers, they're formidable. But when it comes to scaling, going to production seriously, maintaining the product over time, you're better off calling someone who also uses AI, but with a real methodology and the programming skills to keep it in check.
What you actually want
Ask yourself the right questions:
Do you need to validate the idea or launch the product?
If you're validating: no-code or AI tools are sufficient. Don't spend €50,000 on that.
Do you need a production product, with real paying users?
Then you need quality code, solid architecture, auth and payments that actually work.
What's your timeline?
If you have 3 to 6 months, an agency might be worth considering, with the budget that comes with it. If you need something in a few weeks, the options narrow drastically.
What's your real budget?
Not the ideal budget. The budget available today, before your first sale.
For most early-stage founders, the honest answer is: under €10,000, in under a month, with a product that holds up in production.
Startup Express: the fourth option
I built Startup Express specifically to address this need.
The principle: I build your SaaS MVP in 10 calendar days. You pay €7,000 on delivery, not a single euro before.
What you get:
- A complete web application, deployed to production
- Secure authentication (sign-up, login, session management)
- Stripe payments integrated (subscriptions, one-time, webhooks)
- Multi-tenant architecture if your SaaS needs it
- Modern stack: Next.js, PostgreSQL, Vercel; you own 100% of the code
- Delivered in 10 days, not 10 weeks
What it's not:
It's not a no-code prototype. It's not AI-generated code left unreviewed. It's production code, written by a developer with 10 years of experience who has built dozens of SaaS applications.
Who it's for:
- Founders who have validated their idea and need a real product fast
- Entrepreneurs stuck on a no-code or AI prototype that won't make it to production
- Startups that need a solid demo for investors or early customers
Who it's not for:
- Very complex projects with dozens of features (we can talk case by case)
- Founders who don't yet know what they want to build

FAQ
How much does SaaS development cost with an agency in France?
For an MVP, expect between €40,000 and €100,000 with a specialist agency. Timelines are typically 3 to 6 months. It makes sense if you have solid funding and complex requirements. For an early-stage founder without funding, it's rarely the right option.
Can a freelance really build a complete SaaS?
Yes, technically. But a solo freelance handles everything sequentially, which stretches timelines. The real risk is reliability: if the freelance is unavailable, your project stops. Always check references, delivered projects, and make sure you have a clear contract on deadlines and deliverables.
Can you build a SaaS with Bubble or Webflow?
For a prototype or idea validation, yes, it's even one of the best options. And it can actually scale up to a point, contrary to what's often written. The real issues are elsewhere: costs that rise with usage, dependency on the platform (vendor lock-in), and the fact that you don't own your code. For a structure that aims to become a real long-term business, these constraints are worth anticipating.
What's the difference between an MVP and a prototype?
A prototype validates an idea; it can be built in no-code or with AI tools. An MVP (Minimum Viable Product) is a production product, with real users, real authentication, real payments. That's what you need to acquire your first paying customers.
What kind of project is Startup Express for?
SaaS projects with a clear, defined scope: a validated idea, identified priority features, a need for fast delivery. Ideal for founders who have a prototype (no-code or AI) and want to move to a real production product, or for those starting from scratch with a clear vision.
What if my project is more complex than what Startup Express covers?
Let's talk. For larger projects (marketplace, complex business app, multiple integrations), I offer custom web development with transparent pricing. You can also email me directly at hello@manuelcoffin.fr.
