The generated stack has opinionated defaults. A Lovable app is a generated React frontend with a managed backend, Lovable Cloud or your own Supabase project. Excellent defaults, until your product needs something they were not shaped for: heavy background processing, complex integrations, or a data model the generated schema never anticipated.
Built with Lovable, engineered by KUMO
Your Lovable app proved the idea. We make it hold at scale.
Lovable turned a prompt into a running product, and that got you here. What it did not give you is security you can prove, a data model that scales, or code anyone on your team can explain, because no prompt does. When the users, the money, and the data are real, a demo is not enough. We engineer Lovable-built products into production software you own outright: audited, secured, and built to last, one build instead of a credit bill that climbs every time it breaks.
KUMO is an independent engineering studio and is not affiliated with Lovable.
The uncomfortable question
Can you explain what your app does when it fails? Who owns it? Is your customers' data actually safe?
If the honest answer to any of those is "not really", you do not have a production product yet. You have a demo that happens to have users. That is not a criticism of Lovable, it is the difference between generating software and engineering it, and it is exactly the gap we close before it closes on you.
Where Lovable stops
Specific, and factual.
The credit economics invert at exactly the wrong moment. You pay per generation, fixes included. The more complex your app, the more each change costs and the more it breaks, so the bill accelerates precisely when the product succeeds.
Generated security still needs an engineer's review. Lovable added its own security scans, and they help, but they do not replace application-specific review of your auth and access rules. In April 2026, a flaw in the platform itself let any free account read other users' source code, hard-coded Supabase credentials, and live customer data, and scans of vibe-coded production apps generally find a majority with security issues. Before real users trust you with their data, a human engineer should have read how yours is protected.
Nobody on your team can explain the code. Which is survivable until an investor's technical advisor, an enterprise customer's security questionnaire, or a 2am outage asks someone to.
What KUMO does with a Lovable app
Audit, stabilise, then the right-sized path.
The Lovable audit
We export via Lovable's GitHub sync and read what was generated: auth, row-level security, secrets, data model, dependencies. You get a plain-language report of what is solid, fragile and dangerous, in days.
Stabilise
Rotate exposed keys, fix auth and access rules, and close the holes an attacker would find first. This lands before anything else, inside the same Starter Build.
The right-sized path
We pick the smallest fix that actually works, not the biggest invoice. There are three ways it can go, shown below.
Keep shipping fast
Our engineers use the same AI coding tools you do, under senior review. Lovable-speed iteration continues; unreviewed code stops.
Harden in place
The app stays on its stack; we add tests, monitoring, reviewed security and CI/CD. Right when the product fits the stack and just needs to stop being fragile.
Keep the front, engineer the back
The generated frontend stays; the backend, data model and integrations become engineered systems. Right when the product outgrew the generated schema. Supabase stays where it fits, it is in our own production stack.
Full graduation
A custom build with the Lovable app as the living spec, the cheapest specification document you will ever have written. Right when the product and the platform have fully diverged.
Signs it is time
Any one of these is usually enough.
- an investor or enterprise customer asked a security question you could not answer
- the same fix has been prompted three times and keeps regressing
- the credit bill is growing faster than revenue
- you need a feature Lovable keeps failing to generate
- you are about to charge money or store sensitive data
- you cannot explain how login works
What it costs
What scaling a Lovable app costs
Three live bands, the same as our custom software work. The audit is the start of the first one, never a separate fee.
The Lovable audit starts every engagement, inside the $20K to $50K Starter Build (4 to 16 weeks), which also covers harden-in-place and most keep-the-front rebuilds. Full graduations and multi-workflow platforms run $50K to $100K (16 to 24 weeks). Ongoing engineering $5K to $10K per month, cancel with 30 days notice. If the audit says your app is sounder than you feared, we tell you, and you keep your money.
Proof
Engineered systems on live revenue.
Equipp (Ralco Group). A production B2B and B2C rental marketplace. In the client's own Clutch review, the work included rebuilding the billing system and repairing a broken payment gateway on a live revenue system, the kind of hidden fragility an audit catches early.
Read the case study →CampaignHQ. Our own SaaS, built and operated by us end to end: auth, billing, data model, monitoring, the parts a generated app never gets. Live on G2 and Capterra, running on AWS, shipping to customers every day.
Read the case study →The Lovable stack is ours too. Supabase, React and TypeScript are in KUMO's own published production stack, so we engineer on the exact ground a Lovable app stands on. Keeping what fits is not a favour to you, it is how we already work.
How we build →The engineering behind it
What a Lovable engagement includes.
- Codebase export via Lovable's GitHub sync
- Security audit across auth, RLS policies, secrets, dependencies
- Postgres/Supabase data-model review and redesign
- Test suites and evals before changes ship
- Sentry, tracing and cost observability
- CI/CD with rollback
- Documented handover, full IP, your GitHub organisation
FAQ
Lovable to scale, answered straight.
Can you take over my Lovable project?+
Yes. Export via GitHub sync, audit, stabilise, then the right-sized path: harden in place, engineer the backend, or full graduation. Your app stays live throughout.
Can I get my code out of Lovable?+
Yes: Lovable syncs your codebase to GitHub, and you own your code. Getting it out is easy. Knowing whether it is safe to build a business on is the audit's job.
Do we lose Supabase or Lovable Cloud?+
Usually not. Whether your app runs on Lovable Cloud or your own Supabase project, if that backend fits your product it stays and gets engineered properly: schema, row-level security, backups, monitoring. Supabase is in KUMO's own production stack, so this is not a rip-out by default.
How fast can security issues be fixed?+
Exposed secrets and auth holes: days, not weeks. That work lands first in every engagement, inside the Starter Build.
How much does it cost to scale a Lovable app?+
Audit plus first engineering phase inside $20K to $50K over 4 to 16 weeks. Full graduation to a custom platform $50K to $100K. Team on retainer $5K to $10K per month.
Is Lovable bad? Should I not have used it?+
Lovable is good at exactly one thing: turning a prompt into a running demo, fast. The costly mistake is assuming a demo that works is a business that is safe to run and ready to scale. It is not, and closing that gap is an engineering job, not another prompt.
Do you build new products with Lovable?+
We prototype with AI-generation tools where speed to a testable product wins, and we engineer everything that ships to production: senior-reviewed, tested, observable. You get the speed without betting the company on unreviewed code.
Who owns everything afterwards?+
You do: code, infrastructure as code, docs, in your GitHub organisation from day one. No lock-in to KUMO, either.
Built something real on Lovable? Let's make it unbreakable.
30 minutes, no deck. Walk us through the app and the wall. We will tell you what needs securing this week, which path fits, and exactly what it costs. If the honest answer is "keep prompting", you will get that too.
