Can Kyln fix a few urgent issues without an audit?

Small production issues can be discussed, but fragile prototypes usually need a proper review first. Otherwise fixes tend to hide the risk instead of reducing it.

What does launch readiness cover?

Auth, permissions, data model, deployment, hosting, security, cost control, backups, monitoring, error handling, testing and handover.

Kyln Build use case · Prototype rescue

Your AI-built prototype is not production software yet.

Prototype rescue is a Kyln Build use case. Claude, Cursor, Lovable, Replit, Bolt, v0 and similar tools can prove the idea. Kyln decides what is worth keeping, then makes the result safe for real users. A focused Review starts from £1,500.

Fit and buying triggers

The right pressure leaves marks.

Architecture, auth, permissions, database design, deployment, observability, testing, cost control and ownership.

Good fit

Built with AI coding, no-code or low-code tools.
The product looks impressive but breaks under real use.
There is a pilot, waiting list, investor pressure or real internal users.
The team needs an adult review, not a generic agency pitch.

Buying triggers

The app keeps breaking or cannot deploy reliably.
Nobody fully understands the database, auth, permissions or hosting.
There are no tests, logs, backups, monitoring or security model.
The prototype has been shown to customers and now needs to survive them.

What changes

From heat to useful form.

Outcome 01

A clear salvage, refactor or rebuild recommendation.

Outcome 02

A launch-readiness score across architecture, security, data and deployment.

Outcome 03

A prioritised fix list tied to user and business risk.

Outcome 04

A route from impressive demo to credible pilot.

By tool

Start from the tool that built it.

Each builder fails in its own way, so each gets its own page: what breaks, what survives a takeover, and what the review reads.

Lovable

Make your Lovable app production-ready

RLS policies, exposed keys, half-wired auth and one-environment deploys. The Lovable-specific route to production.

Read the Lovable page

Bolt

Make your Bolt app production-ready

Apps that run in the sandbox and break on deploy: secrets, Supabase security, silent regressions. The Bolt-specific route to production.

Read the Bolt page

Make your v0 app production-ready

The interface exists; the product behind it does not yet. Data, auth and APIs on the stack v0 already ships. The v0-specific route to production.

Replit · Cursor · Claude Code · homegrown — the review covers those too

Proof shapes

The work is judged by what keeps behaving.

Product strategy · MVP build

Founder builds

Turning a commercial idea into a scoped product, a usable first release and a supportable technical foundation.

Audit · Launch readiness

Prototype rescue

Reviewing fragile AI-built products across architecture, auth, data, security, deployment and ownership before launch pressure hardens the wrong decisions.

Infrastructure · Support

Production infrastructure

Deployment, hosting, monitoring, backups, permissions and maintenance for web products that need to keep behaving after the first release.

Qualification

Questions before the clay goes in.

These are the questions that separate serious work from vague intent.

Q01

What tool was it built with?

Q02

Is the code accessible?

Q03

Is it live anywhere?

Q04

Are real users using it?

Q05

What breaks most often?

Q06

How are auth, data, hosting and backups handled?

Q07

Are you trying to salvage, refactor or rebuild?

Production readiness · free · 2 minutes

Is your AI-built product safe to sell yet?

The Production Readiness Scorecard is a two-minute self-assessment that grades how close your product is to something you can safely put in front of paying customers, and names the risks standing in the way.

01
Describe what you built
One line on what your product does and how many paying customers it has today.
02
Answer honestly
A short set of pointed questions across auth, data, security, testing and operations.
03
Get your grade and risks
An instant letter grade and a “% ready” score, then your three biggest risks ranked worst-first, specific to what you’ve built.

No. The point of the audit is to decide honestly. Some prototypes can be hardened. Some need a clean rebuild. Some are useful only as product discovery.
