"How much does it cost to build a SaaS" has no single answer because the cost is set by who builds it, not what it is. The same product is $200 in AI-builder credits, a $30,000 freelance project, a $120,000 agency engagement, or 40 percent of your company, depending on the path you pick.
Here are the real 2026 numbers: an AI app builder gets you a working product for $25 to $200 per month in days; no-code platforms run $2,000 to $8,000 with a builder's help over 2 to 6 weeks; a freelancer builds a simple MVP for $10,000 to $40,000 in 2 to 4 months; a fixed-scope senior build runs $15,000 to $60,000 in 4 to 8 weeks; an agency charges $40,000 to $150,000+ over 3 to 6 months; and a technical cofounder costs no cash but 15 to 50 percent equity. Complex products (AI features, marketplaces, payments) land at $80,000 to $150,000+ on any paid path.
I have built or rescued SaaS products through five of these six channels over 20 years, most recently a lot of category two, so the failure modes below are observed, not theoretical.
How do the six approaches compare?
| Approach | Cash cost | Time to launch | Equity cost | Biggest risk |
|---|---|---|---|---|
| AI app builder (Lovable, Bolt, Replit, v0) | $25-$200/mo + your time | Days-2 weeks | None | Shipping insecure by default; 40.6% of scanned Supabase apps leaked data |
| No-code platform (Bubble, Glide, Webflow) | $2,000-$8,000 with help; $30-$400/mo tooling | 2-6 weeks | None | Platform ceiling; migration is a rebuild |
| Freelance developer | $10,000-$40,000 (simple MVP) | 2-4 months | None | Quality variance; single point of failure |
| Fixed-scope senior build / sprint | $15,000-$60,000 | 4-8 weeks | None | Scope discipline required; wrong for open-ended R&D |
| Dev agency | $40,000-$150,000+ | 3-6 months | None | Cost overruns; you still own product decisions |
| Technical cofounder | $0 cash | 3-6 months (incl. the search) | 15-50% | Most expensive option if the company works |
Ranges reflect 2026 US-market pricing for a real SaaS (auth, billing, a core workflow, production hosting). Offshore agencies run 40 to 60 percent cheaper with corresponding management overhead.
What do AI app builders really cost once you count the risk?
The sticker price is genuinely tiny: Lovable, Bolt, Replit, and v0 subscriptions run $25 to $200 a month, and a motivated non-technical founder can have paying users in a week. For pure validation, nothing else comes close, and recommending anything else for a demo or a waitlist test would be self-serving nonsense.
The honest caveat is what happens when the prototype quietly becomes the product. In July 2026 we scanned 66 live apps built with these tools. Among the Supabase-backed ones, 40.6 percent had at least one database table readable by an unauthenticated stranger, and 15.6 percent exposed clearly sensitive data: user records, private messages, bookings. Nothing was "broken" in the code; the AI simply never wrote the database policies that separate one user's data from another's.
So price this path correctly: near-zero to launch, plus a real remediation line item before you store data that matters, anywhere from a $0-to-$299 security check to a $4,000-$15,000 hardening pass, to a full rebuild at the freelancer or sprint price above. Founders who budget that from day one do fine. Founders who discover it from a customer email do not.
When does a freelancer beat an agency (and vice versa)?
Freelancers ($10,000-$40,000 for a simple MVP, roughly $50-$150/hr) are the best cash-for-value path when three things are true: your scope fits in one person's head, you can evaluate their work or know someone who can, and you accept that one person means one bus factor. The variance is the price of the discount. The same $25,000 buys you a disciplined senior who ships or a disaster you discover at month three, and non-technical founders struggle to tell which they hired until late.
Agencies ($40,000-$150,000+) sell you a team, a process, and continuity. That is real value for mid-to-complex builds, multi-role products, integrations, compliance surface, where one freelancer would drown. The two failure modes to watch: change-order economics (the quoted price is the entry price) and the seniority bait-and-switch, where the people who scoped your project are not the people building it. Ask who, by name, writes your code.
Fixed-scope senior builds sit between the two: a defined deliverable at a fixed price ($15,000-$60,000), typically led by one senior engineer with backup rather than a junior team with process. This is the model I run at Continuum (sprint details here), so weigh my framing accordingly. It is the strongest option when the scope is crisp and speed matters; it is the wrong option for exploratory products where the spec will change weekly, because fixed scope punishes churn.
Is a technical cofounder cheaper than paying for the build?
Run the arithmetic before answering emotionally. A technical cofounder joining pre-product typically takes 25 to 50 percent equity; joining post-MVP, 15 to 30 percent (full breakdown by stage here). A 40 percent stake at a $5 million valuation is $2 million of value, transferred in exchange for work you could buy for $30,000 to $60,000.
That trade is still sometimes right, because a real cofounder is not a build channel. You are buying a decade of technical judgment, a partner who carries 2 a.m. pages, and someone whose upside is your upside. If that is what you need, the equity is fair. If what you actually need is "someone to build version one," you are massively overpaying with the most expensive currency you have, and the search itself (3 to 6 months, often longer) is slower than any paid path. The alternatives to a technical cofounder are worth reading before you give anyone half your company.
Which approach should you pick?
The decision compresses to three questions:
- Is demand proven? No: use an AI builder or no-code, spend under $500, and treat it as a disposable experiment. Yes: continue.
- Is real customer data involved yet? The moment it is, either harden the cheap build (budget $300 to $15,000 depending on findings) or move to a professionally built version. This is the step the "I built a SaaS for $95" posts skip.
- Is your scope crisp or exploratory? Crisp: fixed-scope build or a vetted freelancer, $15,000 to $60,000, live in 4 to 8 weeks. Exploratory or complex: agency or in-house/cofounder, $80,000+ and months, because you are paying for adaptation, not just construction.
One number to keep in your head through all of it: the cheapest working version of your product costs under $200, and the median professionally built MVP costs about $30,000 to $50,000. The whole game is spending the first number to earn the confidence to spend the second, and not accidentally running a real business on the first.
If you are stuck between two of these paths, book a call and bring the actual scope. Fifteen minutes of "that is a freelancer project, not an agency project" is often worth $50,000.
