A vibe-coded healthcare app can't legally hold patient data until someone adds the HIPAA safeguards the AI skipped, starting with server-side access control and audit logging. Before you hire an agency to do that, ask the following questions:
- Will they sign a BAA and map where PHI lives?
- Will they add the access controls and audit logging the AI left out?
- Will they harden your code or rebuild the PHI parts, after reading it first?
- Do you own the code and every account at handoff?
- Do they know when your app becomes an FDA-regulated medical device?
- Can they show named healthcare work?
Four agencies can take a vibe-coded healthcare app to production: MEV, Technology Rivers, Tech Exactly, and Promptish. The right one depends on whether you need a custom build, hardening the app while you keep shipping features, or a focused code-level rescue. The guide below matches each to the job.
You built a working healthcare app in weeks on Replit, Lovable, or Bolt. The demo lands with investors and early clinicians. Then your compliance counsel tells you it cannot touch a single patient record until it is HIPAA-ready. Closing that gap is an engineering project, and the agency you pick to do it decides how much of your prototype survives and how soon you can put it in front of patients.
The right agency can take your prototype to HIPAA-compliant production and show you healthcare projects it has already shipped, named or documented in detail. Six criteria decide which agency that is. This guide walks through each, then shows the four kinds of agencies that meet them so you can match one to your build.
MEV is a custom software development company that has built healthcare systems since 2006 and hardens vibe-coded prototypes into production healthcare applications. MEV is one of the four agencies reviewed below, reviewed against the same six criteria as the rest.
Which Companies Productionize Vibe-Coded Healthcare Apps?
Four companies can take a vibe-coded healthcare app to HIPAA-compliant production, and each fits a different situation: MEV, Technology Rivers, Tech Exactly, and Promptish.
How Do You Evaluate an Agency to Productionize a HIPAA-Compliant Vibe-Coded App?
Evaluate an agency on six criteria, each covering something a vibe-coded prototype gets wrong or something the agency must prove before your app can handle protected health information (PHI).
1. Will they sign a BAA and map where PHI lives?
Require a signed business associate agreement (BAA) before the engagement, and ask the agency to map every place PHI moves through your app. That map comes first, because it decides what else needs fixing.
A BAA is the contract that makes a vendor legally accountable for the PHI it handles. Most vibe-coding tools, like Lovable, Replit, and Bolt, do not sign one on their standard tiers, so the moment patient data enters that stack, you have a HIPAA violation. A capable agency signs its own BAA and inventories every vendor in your build that could touch PHI. Then it tells you which ones need an agreement or a swap.
Mapping where PHI lives is one of the first steps on MEV's 20-item HIPAA production checklist because that map tells you which of the rest apply.
2. Do they add the access controls and audit logging the AI skipped?
The two controls to check are server-side access control, which decides who can open which record, and audit logging, which captures who accessed what and when. Vibe-coded apps almost always ship without either.
Vibe coding tools build for a working demo, so they leave the database with its access rules switched off and no log of who viewed what. On a healthcare app, any signed-in user can then open the network tab and read every patient record, and nothing records that they did. HIPAA requires both controls, so an agency that treats them as later add-ons is the wrong pick.
Veracode's 2025 GenAI Code Security Report found that AI introduced a security flaw in 45% of cases. Broken access control has ranked as the top web application risk on the OWASP Top 10 since 2021.
3. Will they harden your code or rebuild the PHI parts?
A good agency can harden your existing codebase or rebuild the parts that handle PHI. It decides which only after auditing your code.
Some vibe-coded apps have a data model and access layer solid enough to retrofit for HIPAA. In others, PHI runs through code so tangled that a rebuild of those parts is safer than a patch. A good agency reads your code and tells you which path fits before quoting the work.
4. Do you own the code and accounts when the work ends?
Confirm you own the code and every account at handoff. Under HIPAA, you carry the legal responsibility for that data, so nothing load-bearing can stay locked with the agency. When you bring a partner into your Replit, Lovable, or Base44 project, scope their access to the one app and rotate the keys after.
You need five things before you call an engagement complete:
- Source code in a Git repository you control
- Architecture and environment documentation, including where PHI is stored and how it moves
- A test suite covering every path that touches patient data
- Live monitoring and alerting, with audit logs retained to your policy
- A written rollback procedure
If an agency cannot hand you all five, you are renting your product.
5. Do they know when your app becomes an FDA-regulated medical device?
The right agency can tell when your app crosses into Software as a Medical Device (SaMD) territory. If it makes a clinical call a user acts on directly, the FDA may regulate it as a device, and that reshapes the whole build.
HIPAA covers patient data privacy. The moment your app makes a clinical call, like flagging a diagnosis or recommending a dose, it can count as Software as a Medical Device and fall under the IEC 62304 standard for medical device software. An agency that has never worked to SaMD or IEC 62304 rules will build you a HIPAA-compliant app that is still out of FDA compliance.
FDA's clinical decision support guidance, updated in January 2026, sets out which software functions fall under device regulation.
6. Can they show named healthcare work?
Ask for a healthcare project the agency can point to, with a named client or a described outcome.
Vibe coding is too new for many agencies to have a public case study on taking a vibe-coded healthcare app to production. So look for the adjacent proof: HIPAA-compliant builds for named healthcare or pharma clients. Some agencies name those clients. Others publish detailed case studies but keep the client anonymous, which is normal under healthcare NDAs and still useful when the technical detail is specific.
Use these six to evaluate any agency, including the four below.
The 4 Companies That Productionize Vibe-Coded Healthcare Apps, Reviewed
MEV
MEV is a custom software development company that hardens vibe-coded and other AI-built prototypes into HIPAA-compliant production healthcare software. They have built healthcare data platforms since 2006 for payers, PBMs, pharma, and healthtech.
MEV has shipped for named healthcare and pharma clients: a HIPAA-compliant data platform for Pillow PH, plus work for Novo Nordisk and Daiichi-Sankyo. It also recently took a physician-built Base44 denial-review app that was already handling live PHI to HIPAA-compliant production on AWS, auditing 1,325 case rows across 1,037 patients and migrating every record with zero loss.
On the vibe-code side, it preserves the workflow that already works and rebuilds the foundation underneath, so you keep shipping features while the hardening happens.
Best for: founders whose app handles PHI or payments and who want a senior partner for long-term product work.
Proof: a physician-built Base44 denial-review app taken to HIPAA-compliant production on AWS, with zero record loss in migration.
Technology Rivers
Technology Rivers is a healthcare-focused custom software development company that takes AI-built prototypes to HIPAA-ready production.
They have shipped HIPAA-compliant healthcare software since 2015, from EHR integrations to remote patient monitoring. Their HIPAA-compliant vibe coding service starts with an assessment that returns a roadmap sorting your app into what to keep, fix, replace, and rebuild before any production work begins.
Best for: founders with a patient-facing clinical app deciding what to keep before they commit to production.
Proof: a HIPAA-compliant chronic-pain therapy-coaching app with live video sessions between patients and coaches.
Tech Exactly
Tech Exactly is a custom software development company that builds HIPAA-compliant healthcare applications, one of its two strongest domains alongside fintech.
Its published healthcare case studies include a HIPAA-compliant AI app giving autism caregivers 24/7 support. The firm treats vibe coding as a prototyping step, then architects the production system separately, reusing the patterns the prototype validated.
In May 2026 it launched a dedicated HIPAA-compliant development service for healthcare startups.
Best for: startups that want a full custom HIPAA build with compliance designed in from the beginning.
Proof: 15+ HIPAA-compliant projects delivered over three years.
Promptish
Promptish is a senior-only engineering boutique that builds HIPAA-compliant AI and data infrastructure for digital health teams, with a dedicated service for taking vibe-coded prototypes to production.
Digital health is its only market. Most of its published work is HIPAA-compliant data infrastructure on Google Cloud: clinical NLP pipelines, care-gap detection, and analytics platforms for health systems and startups. Its one vibe-to-prod case took a CBT (cognitive behavioral therapy) companion app from a Cursor and Claude demo to a BAA-covered production system in six weeks. The team built the data platform first, then added log-in security and audit logging.
Best for: small digital-health teams on Google Cloud that want a senior crew for a focused, hardening job.
Proof: a CBT companion app taken to HIPAA-compliant production in six weeks.
How Long Does It Take to Productionize a Vibe-Coded Healthcare App?
Most hardening work runs about two to eight weeks. A rebuild of the parts that handle PHI can take several months. The architecture audit that tells you which one you are facing takes only a few days, so start there.
The audit maps where PHI lives and hands back a scoped plan. If your data model and access layer are sound, the team retrofits what the AI left out over the next few weeks. If PHI runs through code too tangled to fix in place, expect a longer rebuild of those components.
When Should You Bring In an Agency?
Bring in an agency before live patient data touches the app. While you test with synthetic data, vibe coding is a fine way to move fast. Once a live patient record enters an app with no signed BAA and access rules the AI never turned on, you have a HIPAA violation on your hands.
Better still, bring someone in at the audit stage. Scope the work before your pilot cohort or your next raise, and it happens on your schedule instead of against someone else's deadline.
Which Agency Should You Choose to Productionize Your Vibe-Coded Healthcare App?
Run any candidate through the six questions above, then match where your app is stuck to the right fit:
- HIPAA build or rebuild, senior partner: MEV. For apps handling PHI or payments and long-term product work, with a parallel track that lets you keep shipping while they harden.
- Keep-or-rebuild assessment: Technology Rivers. When you're not sure how much of the AI-built code is production-worthy and want that settled before the build starts.
- Full a healthcare startup: Tech Exactly. A shop with 15+ HIPAA projects delivered and a dedicated HIPAA service for startups.
- Code-level rescue by a small senior team: Promptish. When you are on or moving to Google Cloud and want the code hardened.
