From agentic-built prototype to the next level
Online builders are brilliant at getting you started — then deployment, security, runaway bills, and the bug that won't die get in the way. We take agentic-built apps from stuck to shipped, and build fresh web and mobile apps from a blank page. However it starts, you keep the code.
Every line written locally in New Zealand. Clear, fixed prices.
Sound familiar?
Where agentic-built apps get stuck
Built with Lovable, Bolt, Replit, Cursor, or their kin — and hit a wall? The pattern is remarkably consistent: a fast, exciting start, then the same walls. Every one of them is routine work for a senior engineer.
It works on my machine
The preview runs, but going live is a different world — domains, deploys, environments, databases. We take apps the last mile and set the pipeline up so updates stay easy.
Surprise bills
Builder credits burn fast in debugging loops, and usage-based hosting and API keys can spike without warning. We map what things actually cost, then tune the app so the bills behave.
Security you can't see
Exposed keys, open databases, and missing access rules are the most common gaps in builder-made apps. We audit, lock everything down, and show you exactly what changed.
Login and payment walls
Sign-in flows, access rules, and payment webhooks are where builder-made apps break hardest. They're bread-and-butter engineering here — done properly, secure from day one.
The bug that won't die
Each fix breaks something else, and the builder keeps circling. A senior engineer reads the code, finds the real cause, and untangles it for good.
Stuck at the store gates
Apple and Google reject first-time submissions on permissions, privacy, and polish. We've taken apps through both reviews — we know what they look for.
The pattern, documented
A 2026 academic audit of more than 9,000 agentic-built apps found 91% carried at least one security vulnerability, and an independent scan of 380,000+ found around 40% exposing sensitive data. If no engineer has read your app yet, a review is cheap peace of mind.

Services
What we do
One senior team across the whole stack — rescuing builder-made apps, building from scratch, and everything in between. Projects big or small.
App rescue & finishing
Built with an online builder and stuck? We review the code, fix what's broken, lock down security, and take it live — then hand it back documented. You keep the code.
Fresh builds
Greenfield apps from a clean slate — cutting-edge, built your way on your preferred stack, from first sketch to launch.
Web apps
Professional dashboards, portals, and internal tools — accounts, data, integrations, the works. Secure by design, with full automated testing.
Mobile apps
iOS and Android from one cross-platform codebase, with App Store and Google Play submission handled end to end.
App-store publishing
Privacy policies, support URLs, review compliance — the paperwork both stores demand, done right.
Authentication & SSO
Email and password, OTP verification, Google sign-in, and full account flows — sign-in done properly, secure from day one.
Websites
Marketing sites that load fast, rank well, and look sharp on every phone — bespoke builds, not page builders.
Existing codebases
Bring us code with history — we refactor it, optimise it, or add the new features it needs. Projects big or small.
Care & hosting
Managed deploys, monitoring, updates, and small tweaks — keeping everything fast, secure, and optimal after launch.

FAQ
Questions people ask
I built my app with an online builder. Can you take it over?
Yes — rescuing builder-made apps is core work here. We start by reading the code properly, then give you an honest assessment: fix what's there or rebuild the shaky parts, with a fixed quote for either path before anything starts. The code is yours either way.
What does an app rescue involve?
A full review of the code and security first, then the blocking bugs fixed, keys and access locked down, and a proper production deploy. You finish with a plain-English handover document, so you always understand the app you own.
My app works, but the bills keep climbing. Can you help?
Yes. We map exactly what you're paying for — builder credits, hosting, third-party APIs — then rework the expensive parts so costs track your usage. Small architectural changes often cut bills dramatically.
How can you charge fixed prices when agencies quote hourly?
We're a small studio putting modern agentic tooling to work, not a big agency — the overheads that force hourly billing mostly don't exist here. Fixed pricing also forces honest scoping up front, which we prefer anyway: you know the number before we start, and it doesn't move unless the scope does.
What's not included in a fixed price?
Third-party costs you'd pay anyway — domain registration, app-store developer fees, paid services like SMS gateways — and scope we agree to add later. Everything else in the quote is included; if it's in the deliverables list, it's in the number.
Do you only work with Auckland clients?
We're based in Auckland, New Zealand, but we work with clients anywhere in NZ. Almost everything happens over email and a staging link, so location rarely matters.
Is any of the work outsourced?
No. Design, engineering, testing, and deployment all happen locally in New Zealand, carried out by the people you deal with directly. When you email us, you're talking to the hands on the keyboard.
How much experience comes with a build?
Over eight years of professional software engineering across some of New Zealand's leading tech companies and financial institutions. It shows up in the finished app — secure architecture, full automated testing, and engineering judgement you can lean on.
Who owns the code and design?
You do, fully. On final payment everything is handed back to you — the code, the design, and the accounts. Take the repositories wherever you like, or keep us on for hosting and care under a plan — your choice.
How involved will I be during the build?
You're part of the whole build. Each week brings a fresh preview on a private staging link — click through, tell us what to change, and watch it take shape. Your feedback is what shapes the app to your imagination.
Do you design the look and feel, or just write the code?
Both — the aesthetic is shaped with you, not around you: typography, styling, motion, all of it. Professional, high-quality finishes with beautiful, purposeful animations, and every effect carries a reduced-motion fallback so accessibility is never an afterthought.
How long does a project take?
A launch site is typically under a week, a business site 1–3 weeks, and apps or web apps are scoped per project — the fixed quote always comes with a delivery window.
Do you handle the app store submission process?
Yes — that's a core speciality. Apple and Google each require privacy-policy URLs, support contacts, and review compliance before an app goes live. We prepare all of it, submit, and manage the review process through to approval.
Stuck app or fresh idea?
Either way, let's bring it to life. Tell us what you're building — big or small — and a fixed quote comes back within two business days. Or just email hello@nextleveldevs.co.nz.
