Already have a working frontend?
Keep it. A React, Vue or plain-JavaScript interface does not need to own the security model. We can operate as an authenticated backend behind it.
For people who already built something
You built the app. Now make it ready for the real world.
Vibe coding gets you from an idea to a working product remarkably fast. A working product is not automatically a launch-ready SaaS business.
We add the security, authentication, user management, billing, infrastructure and ongoing maintenance that should never be improvised — around the application you already have.
Keep what makes your application unique. Add proven systems around everything that protects it.
No rewrite pitch. No framework religion. We start with the product that exists today.
Yours — keep it
Your application
The feature that made your product interesting in the first place. However you built it, in whatever stack, wherever it runs.
Ours — add it
The SaaS foundation
A decade-old, actively maintained base for the parts that carry real risk.
- auth
- permissions
- tenancy
- billing
- APIs
- audit logs
- backups
- updates
The problem
The last mile is a different problem
Your application works. Maybe it works really well.
Now you want to let strangers create accounts. Store their data. Charge their credit cards. Give different users different levels of access. Reset passwords. Manage subscriptions. Expose APIs. Handle abuse. Back up production data. Patch vulnerabilities. Recover when something goes wrong.
That is a different problem than building the feature that made your product interesting in the first place.
You do not need to stop vibe coding. You need to know where vibe coding should stop.
Vibe-code what makes your product unique. Use proven systems for everything that protects it.
The approach
We are not here to rebuild your app
Vibe2SaaS is designed to work around and alongside existing applications. Depending on the project we provide backend APIs, integrate services directly, or put an existing frontend behind a mature authentication and authorization layer.
Built it with AI assistance?
Good. How the code was created matters far less than what it actually does. We evaluate the application that exists today, not the way it got here.
Mixed stack, odd history?
PHP, JavaScript, API-driven, half-inherited from a freelancer — we start there. The goal is not to replace good work. The goal is to make it launchable.
What we add
The infrastructure you should not spend six months building
Every project is different, but the SaaS foundation commonly covers these. You should spend the next six months making your product better instead.
Identity & accounts
- Authentication and secure account lifecycle
- Registration, verification and recovery
- MFA, passkeys and modern options
- Self-service account management
Roles & authorization
- Centralised roles and permissions
- Access rules around existing features
- Entitlement checks tied to the plan
- Administrative access boundaries
Organizations & tenancy
- Teams, companies and groups
- Per-tenant data boundaries
- Invitations and membership
- Cross-tenant access reviews
Billing & entitlements
- Subscription plans and payment
- What each customer actually bought
- Upgrades, downgrades and cancellation
- What happens when payment stops
APIs & support tooling
- API authentication and access control
- Keys, scopes and revocation
- Administrative and support screens
- Rate limiting and abuse controls
Operations & upkeep
- Secure production deployment
- Monitoring, logging and backups
- Audit and activity trails
- Ongoing platform and security updates
The assessment
Start with the application you have
We look at architecture, code, dependencies, authentication assumptions, APIs, secrets, data handling, uploads, authorization and the deployment environment. Then everything lands in one of three buckets.
Keep it
It works, and it does not need to be replaced
The interface your users like. The logic that makes the product worth paying for. The integration you spent three weekends getting right. Working software is an asset, and rewriting it for architectural purity is a cost with no customer-visible benefit.
This is usually the largest bucket, and we would like to keep it that way.
Fix it
The concept is sound, but something needs hardening first
A query built by string concatenation. An upload folder that accepts anything. An admin check that trusts a value from the browser. A secret committed to the repository. An endpoint that returns another customer's record if you change the ID.
These are ordinary findings in software that was never meant to face the public. We fix them rather than hand you a report and wish you luck.
Add it
A capability the product does not have yet
Accounts. Permissions. Organizations. Subscriptions. Audit logs. An admin console. Backups. The things that were not needed when the only user was you, and become unavoidable the moment someone pays.
This is where a maintained foundation saves you months of building undifferentiated infrastructure.
The result is a practical path to launch — not an excuse to rewrite your application.
Two-minute self-check
How close is your application to launchable?
Tick everything that is genuinely in place today. Nothing is sent anywhere — the score is calculated in your browser. If you want, carry the gaps straight into the contact form.
Why maintenance matters
More than a one-time security pass
Security is not something that gets finished on launch day.
The foundation behind Vibe2SaaS comes from software and practices that have been actively developed and used in production for roughly a decade, with updates historically averaging about once a month.
A generated authentication system may work today. A library installed during an MVP sprint may be current today. A production application has to still be secure tomorrow, next month and next year.
We can stay involved after launch to maintain the foundation underneath your product while you keep developing the part your customers actually came for.
Your coding assistant's job may end when the feature works. Ours doesn't.
The engagement
From prototype to SaaS
Five stages. Most projects do not need all of them at full depth.
-
Assess
We review the application, identify risks and missing pieces, and determine what can stay exactly as it is.
-
Harden
We address the security issues that should be resolved before real customers and real data arrive.
-
Enable
We add the SaaS capabilities the product needs: identity, permissions, billing, tenancy, APIs, administration, infrastructure.
-
Launch
We help move the combined application into a production environment designed for public use.
-
Maintain
When it makes sense, we keep maintaining the security, platform and operational foundation underneath the product.
You don't need another rewrite
The industry has a bad habit of looking at an existing application and recommending a new framework, a new architecture and a complete rebuild. We would rather ask a simpler question:
What is the smallest responsible path from what you have today to something you can launch?
Sometimes that requires meaningful remediation. Sometimes new backend services. And sometimes a surprisingly small integration puts an already-good application behind mature authentication, authorization and user management.
Fit
Who this is for
Vibe2SaaS may be a good fit if any of these sound like you.
- You vibe-coded a useful application and people are asking when they can buy it.
- You built an MVP and found production authentication more complicated than expected.
- You have a great frontend but need a real backend and user-management layer.
- You built an internal tool and now see an opportunity to sell it.
- Someone else built the core product and you still need the surrounding SaaS infrastructure.
- You have a single-user application that needs accounts, organizations, permissions or subscriptions.
- You are happy to keep building your product but do not want to become an expert in authentication, application security, billing and production operations.
When we are probably not the right fit
If all you have today is an idea and you want someone to build the entire product for you, this is not the service for it.
We are most useful once there is something real to work with — a functional product, a prototype, or a substantial application that needs to become commercial.
Built something that might actually be a business?
Don't throw it away. Show us what you built, tell us where you want to take it, and we'll help determine what it needs before you put real customers on it.
