BYOC Playwright Testing for Healthcare

Bottom line: Healthcare engineering teams subject to HIPAA need test data to stay within their HIPAA-covered environment. TraceLoom's BYOC architecture means Playwright traces — which may contain patient-adjacent DOM data — are written directly to your S3 bucket and never processed by TraceLoom's control plane.

Last updated: April 2026

What does BYOC testing mean for healthcare compliance?

HIPAA's Security Rule establishes technical safeguard requirements for systems that store, process, or transmit Protected Health Information. When your Playwright tests run against patient portals, provider dashboards, or any UI that renders PHI, the resulting traces — full DOM snapshots, network recordings, screenshots — may be PHI-adjacent. Sending those traces to a managed testing platform means PHI-adjacent data is now in a system outside your HIPAA-covered environment.

TraceLoom's BYOC architecture keeps execution inside your AWS account. A cross-account IAM role gives TraceLoom's control plane permission to schedule test runs and surface run metadata — but your EC2 instances handle all compute, and your S3 bucket holds all traces. TraceLoom's control plane is not in the data path and cannot read trace files. The separation is architectural, not just contractual.

BAA coverage is a common question for healthcare teams evaluating any vendor that touches test infrastructure. Because TraceLoom's control plane does not receive or store trace content, many organizations have determined a BAA is not required — but your privacy officer must confirm based on your specific test environments and organizational policy.

The HIPAA-eligible AWS region question resolves cleanly with BYOC: your data plane deploys into the region you specify. If your existing HIPAA BAA with AWS covers US-East-1 and your patient data lives there, your TraceLoom data plane lives there too. No cross-region data transfer, no new PHI storage location, no additional BAA surface to manage.

Why HIPAA-covered teams can't use managed testing platforms

• 1. PHI-adjacent data leaves your environment. Managed platforms require uploading Playwright traces to the vendor's cloud. Any trace that captures rendered patient data is now in a system your BAA scope doesn't cover.
• 2. BAA gaps. Most managed testing SaaS vendors decline to sign BAAs — but without one, routing PHI-adjacent artifacts through them is a HIPAA violation.
• 3. Audit surface explodes. Every new PHI-adjacent SaaS adds a new vendor to your annual HIPAA audit scope, risk register, and incident-response plan.

How TraceLoom supports HIPAA requirements for Playwright testing

TraceLoom's architecture creates a hard boundary between orchestration and execution. The control plane handles scheduling, sharding, and the TraceLoom dashboard — your AWS account provides all compute and storage. This means TraceLoom's infrastructure is never a PHI storage location and is never in the transmission path for PHI-adjacent data. Your HIPAA attestation does not need to expand to cover TraceLoom.

What TraceLoom's control plane receives: test names, pass/fail status, execution timing, worker counts, shard counts. What stays in your account: every Playwright .trace.zip — full DOM snapshots (including any rendered patient data), network recordings, screenshots, console logs. Traces are written directly from your EC2 instances to your S3 bucket over the AWS internal network. TraceLoom's control plane is not in the data path.

The CloudFormation template TraceLoom provides is auditor-friendly. Your privacy officer and security team can review every IAM permission before deployment. The template creates exactly four resource types — an S3 bucket, an SQS queue, an EC2 launch configuration, and a cross-account IAM role — with no wildcard permissions and no cross-region access. There is no black-box vendor trust required.

Disconnection is immediate and clean. Revoking the cross-account IAM role ends TraceLoom's access in real time. Your S3 bucket, CloudWatch logs, VPC configuration, and all trace files remain under your control. No vendor-side data deletion is needed because TraceLoom never held your PHI-adjacent data.

What healthcare compliance teams need to know

How to deploy TraceLoom in a HIPAA-compliant AWS environment

1. 1

   Confirm HIPAA eligibility of your AWS account

   Your privacy officer verifies your BAA with AWS is active and your chosen region is HIPAA-eligible before deploying any new resources.

2. 2

   Review and deploy the CloudFormation stack

   Your security team inspects every IAM permission and resource in the template. Deployment typically completes in under 15 minutes.

3. 3

   Connect your source repo and run your first test suite

   TraceLoom dispatches tests to your EC2 fleet; traces land in your S3 bucket; the dashboard shows only run metadata — no PHI-adjacent content.

Frequently Asked Questions

Does TraceLoom require a Business Associate Agreement (BAA)?

TraceLoom does not receive, store, or process Protected Health Information (PHI). The control plane sees only run metadata — test names, pass/fail counts, timing — which is not PHI under HIPAA. Playwright traces, which may contain PHI-adjacent DOM data, are written directly from your EC2 instances to your S3 bucket and never transit TraceLoom infrastructure. Because TraceLoom's control plane does not receive or store trace content, many organizations have determined a BAA is not required — but your privacy officer must confirm based on your specific test environments and organizational policy.

Can Playwright traces contain PHI?

Yes, potentially. A Playwright trace captures full DOM snapshots, which include any rendered UI — including patient records, provider notes, or account identifiers if your tests exercise those views. This is why data residency matters for healthcare: assume traces may contain PHI-adjacent data, and design so they never leave your HIPAA-covered environment. TraceLoom's BYOC architecture does exactly this.

How does TraceLoom's BYOC architecture address HIPAA's technical safeguards?

HIPAA's Security Rule requires access controls, audit controls, integrity, and transmission security for PHI. TraceLoom's data plane deploys entirely inside your AWS account, governed by your existing controls — your IAM policies, your KMS encryption, your CloudTrail logs, your VPC boundary. TraceLoom does not add a new PHI storage location or a new data transmission path; it uses the ones you already attest to.

What data does TraceLoom's control plane receive from healthcare test runs?

Run metadata only: test names, pass/fail status, execution timing, worker counts, shard counts. Never trace content, never DOM snapshots, never network recordings, never screenshots. The architectural separation is absolute — your EC2 instances write traces directly to your S3 bucket over the AWS internal network; TraceLoom's control plane is not in the data path.

Can we run TraceLoom inside a HIPAA-eligible AWS region?

Yes. TraceLoom deploys to any AWS region, including US-East-1, US-West-2, and other HIPAA-eligible regions. Your data plane — S3 bucket, SQS queue, EC2 instances — all live in the region you choose. Cross-region data transfer is not part of the architecture.

How do we disconnect TraceLoom without impacting our HIPAA-covered data?

Revoke the cross-account IAM role. TraceLoom's control plane immediately loses the ability to launch EC2 instances or enqueue test runs in your account. Your S3 bucket (with all traces), your CloudWatch logs, and your VPC configuration remain intact under your control. There is no vendor-held artifact to retrieve.
