"How much will it cost to build my web app?" is the first question every founder asks, and the hardest one to get a straight answer to. Most studios respond with "it depends" and a discovery call. Useful for them. Frustrating for you.
Here is the honest version, written from the inside.
The Short Answer
In 2026, a production-ready custom web app from a competent studio typically falls into one of three brackets:
- MVP / Phase 1 ($15k to $40k): one core flow, polished UI, auth, a simple dashboard, and a real backend. Built in 4 to 8 weeks.
- Full v1 ($40k to $120k): multiple flows, role-based access, integrations (Stripe, email, analytics), admin panel, and a real product surface. 8 to 16 weeks.
- Scaled platform ($120k to $400k+): multi-tenant SaaS, complex permissions, custom infrastructure, AI features, mobile-responsive PWA, and ongoing iteration. 4 to 9 months.
If a studio quotes you $5k for a "full SaaS," they are either leaving 80 percent of the work for you to discover later, or they are using a no-code tool with a re-skinned template. Neither is inherently wrong. It just isn't a custom web app.
What Actually Drives the Cost
Price is mostly a function of these five variables. If you understand them, you can negotiate intelligently.
1. Scope of the First Release
Every extra screen, role, and edge case compounds. A dashboard with one role is one thing. A dashboard with three roles, each with different permissions, audit logs, and an invite flow, is a different product. Cut ruthlessly for v1. You can always add roles later.
2. Custom Backend vs. BaaS
Using Supabase, Firebase, or a similar Backend-as-a-Service can cut backend cost by 30 to 50 percent. The trade-off is less control over data shape and migrations. For most v1 SaaS products, BaaS is the right choice. We default to it unless there's a strong reason not to.
3. Design Fidelity
A "good enough" Tailwind UI with sensible defaults takes one to two weeks. A bespoke, brand-defining design system with custom illustrations, motion, and a polished marketing site takes four to six weeks. Both are valid. Don't pay for the second if you only need the first to validate the idea.
4. AI / ML Features
A chatbot calling an LLM API costs almost nothing to build (one or two days). A retrieval-augmented system with vector search, evals, and proper guardrails costs weeks. We've covered the patterns and pitfalls of AI integration in detail. The short version: scope the AI feature like a separate sub-project.
5. Who's Building It
A solo freelancer, an offshore agency, a US-based studio, and a hybrid team will quote three to five times different prices for the same spec. None of them are wrong. They are selling different things: speed, communication, accountability, code quality, post-launch support. Pick based on what you actually need.
Where Studios Cut Corners (Watch For This)
If a quote feels too good, it usually means one of these is missing:
- No staging environment. Code goes straight to production. You'll find out about bugs from your users.
- No tests. Refactoring becomes terrifying. Velocity drops six months in.
- Hardcoded everything. Branding, copy, and config baked into components. Editing means engineering tickets forever.
- No CI/CD. Deploys are manual. SSH, FTP, "let me just upload this real quick." Modern apps don't do this.
- No documentation. When you eventually hire in-house engineers, they spend two months reverse-engineering what's there.
These shortcuts usually save 15 to 25 percent upfront and cost you two to three times that within the first year. We wrote more about how to evaluate a studio in our guide on how to choose a web development studio for your startup.
How to Budget if You're a First-Time Founder
A practical budgeting framework:
- Define the smallest version that proves the idea. Not the smallest version that feels safe. The smallest one a real user could pay for.
- Multiply your initial estimate by 1.5. You will discover edge cases mid-build. Always.
- Reserve 20 percent for post-launch iteration. Launching is half the work. The other half is what you learn the first 60 days from real users.
- Don't pay for "future-proofing" you can't articulate. "We're building it so it scales to a million users" is a red flag when you have zero users.
Custom vs. No-Code: The Real Trade-Off
For some products, no-code tools like Framer, Webflow, or Bubble are the right choice, especially for marketing sites, simple internal tools, or rapid validation. They cost less, ship faster, and are easier to edit.
The line gets crossed when:
- You need custom business logic the platform can't express
- You need real database relationships and queries
- You need integrations the platform doesn't natively support
- You're hitting platform limits on users, records, or compute
- You want full ownership of the codebase and infrastructure
If two of those are true, you're probably better served by custom development.
What a Realistic Engagement Looks Like
For most of our founder clients building a SaaS, the first 12 months look like:
- Weeks 1 to 2: discovery, scoping, design system, technical architecture.
- Weeks 3 to 10: build the v1. Auth, core flows, billing, admin.
- Weeks 11 to 12: QA, polish, launch, marketing site.
- Months 4 to 6: iteration based on real user feedback. New features, fixes, performance work.
- Months 6 to 12: scale prep. Observability, integrations, growth features.
Total cost in that pattern usually lands between $80k and $180k, depending on scope. Some founders build a SaaS MVP in 2026 for less by being aggressive with scope and using the right stack.
How to Get a Real Number for Your Project
A useful quote comes from a 30-minute conversation, not a form. The studio should be able to ask you:
- What's the smallest version of this that could ship?
- Who is the user? What's their alternative today?
- What does success look like 90 days post-launch?
If those questions don't come up, you're not getting a quote. You're getting a guess.
At Soleno, we scope every project with a fixed timeline and price before we start. No surprises, no padding, no "it depends." If you're trying to figure out whether your idea is a $20k MVP or a $150k platform, let's have that conversation. We'll tell you straight.
