GAfix
GAfix is an automated audit tool for Google Analytics 4 and Google Tag Manager. It connects read-only to a GA4 property, scores tracking health in under two minutes and flags broken tags, missing conversions and attribution gaps.
What is GAfix?
GAfix is a web platform that inspects a Google Analytics 4 property together with its Google Tag Manager container, then reports what is broken and what it is costing you in reporting accuracy. It is published by NeenOpal Inc., a Delaware corporation based in Newark, New Jersey. The opening argument on the site is blunt: eight businesses out of ten carry GA4 and GTM tracking gaps they know nothing about.
The workflow has three steps. You link your Google Analytics account with read-only permissions, GAfix runs its checks automatically, and you review a prioritised list of action items. The GTM side asks for nothing at all: the container is read from publicly available data, with no login, no container access and no changes made. A complete pass is advertised at under two minutes, against the days or weeks a manual review takes.
Coverage falls into three families. On the GA4 side the tool validates event parameters, conversion event configuration, enhanced measurement settings and data stream setup. On the GTM side it hunts unused tags and triggers, incomplete GA4 events, invalid ecommerce objects, absent Conversion Linker tags, consent mode configuration and weak container naming. A third family targets attribution and reporting: referral exclusion lists, default channel groupings, duplicate event detection and missing data. The features page groups all of this into nine audited areas spanning configuration, tracking, attribution, privacy and governance.
The free tier runs a single audit per account across 11 GA4 checkpoints and 7 GTM checkpoints, view-only and without export. A Pro audit opens more than 50 checks, full explanations and a downloadable Excel report meant to be handed to a developer or a client. Every finding comes with an explanation of what to fix and why it matters, rather than a bare alert.
Three audiences are named on the site: SaaS and product teams tracking trial signups and funnels, ecommerce brands validating purchase events and revenue attribution, and marketing agencies auditing many properties at once. Nothing is installed and no code is changed. GAfix is also listed on AWS Marketplace, with billing consolidated onto the AWS account.
What it does
- Audit a Google Analytics 4 property end to end in under two minutes
- Scan a Google Tag Manager container without ever being given access to it
- Detect misfiring events, missing conversions and duplicate event tracking
- Find dead tags, unused variables and broken or misconfigured triggers
- Check attribution settings, referral exclusion lists and default channel groupings
- Validate ecommerce objects, item arrays and Conversion Linker coverage
- Export findings to Excel and re-audit once the fixes are in place
When to use GAfix / When not to
A quick filter to help you decide if GAfix is the right fit.
When to use GAfix
- SaaS and product teams that need trial signups, feature usage and funnel steps to be counted correctly in GA4
- Ecommerce brands validating purchase events, cart actions and revenue attribution before they distort media decisions
- Marketing agencies auditing many client GA4 properties and GTM containers with a consistent method
- Marketers, analysts and founders who rely on GA4 reporting but have no tracking or coding background
- Data quality and BI owners who need a documented, shareable record of what is wrong in a tracking setup
When not to use GAfix
- Teams whose analytics stack is not Google Analytics 4 and Google Tag Manager, since nothing else is covered
- Anyone expecting the issues to be fixed automatically: GAfix diagnoses and recommends, it never writes to your account
- Organisations that require a signed data processing agreement and a subprocessor list before onboarding a vendor
- Teams wanting unlimited continuous re-auditing on a flat subscription, as a purchased Pro audit cannot be re-run without buying again
- Developers looking for an API, a mobile app or a way to plug tracking checks into a CI pipeline
How to use GAfix
A typical end-to-end flow, from setup to results.
- Create an account on app.gafix.ai, or sign in if you already have one
- Securely link the Google Analytics 4 property you want audited
- Make sure you hold read access on that property - read access is all GAfix asks for
- Leave Google Tag Manager alone: the container is read from publicly available data, with no login required
- Start the audit with a single click and let the checks run automatically
- Wait a few minutes for the results and your tracking health score
- Work through the prioritised action items, each explained with what to fix and why it matters
- Download the Excel report, available with a Pro audit, to share with your team, your developer or your client
- Apply the recommended fixes in GA4 and in your GTM container
- Re-run an audit to confirm the issues are gone - depending on your plan this may require an upgrade or a new purchase
Pros & Cons
Pros
- The free audit is genuinely usable: 18 real checkpoints across GA4 and GTM, enough to judge the tool before paying
- Results arrive in under two minutes where a manual audit takes days or weeks
- GA4 and GTM are covered in the same pass, which many analytics checkers do not do
- Access is strictly read-only on GA4, and the GTM container is never accessed at all
- Findings come with explanations and priorities, so they can be handed straight to whoever will fix them
- No installation, no code change and no GA4 expertise required to run an audit
- Audits can be bought one at a time rather than through a subscription, and are also available via AWS Marketplace
Cons
- Scope is limited to Google Analytics 4 and Google Tag Manager; no other analytics platform is covered
- The tool diagnoses but never repairs: every fix is manual work in GA4 or GTM afterwards
- The free tier is one audit per account, view-only and without export, and a purchased Pro audit cannot be re-run without buying it again
- No public API, no mobile app and no browser extension
- No data processing agreement is published or offered and no subprocessor list exists, which blocks some enterprise procurement
- The homepage claim that nothing is saved, copied or reused is not reconciled with a privacy policy that allows retention, sharing and service improvement
- Published pricing contradicts itself between the pricing page and the help centre, and the pricing page still carries unrelated template blocks

Data, GDPR & hosting
A consolidated view of how GAfix handles your data.
GDPR overview
GDPR is addressed explicitly. The privacy policy, effective 28 November 2025, states it was formulated in accordance with the General Data Protection Regulation and names NeenOpal Inc. as data controller. It sets out legal bases (consent, vital interests, legitimate interests), a chapter of EU user rights covering access, rectification, objection, erasure, portability and withdrawal of consent, a designated data protection officer reachable at admin@GAfix.ai, a grievance forum promising a reply within seven days, and a minimum age of 16. Three gaps matter for European buyers: no representative is designated under Article 27, no data processing agreement is published or offered, and no subprocessor list exists. Transfers outside the user's jurisdiction are permitted under unspecified adequate controls, with no standard contractual clauses named, and disputes go exclusively to New Jersey courts.
Who owns the data?
The terms reserve every right in the site and its content to NeenOpal Inc., with one carve-out: the User's Data. That data - analytics events, metrics, configuration settings, account information, reports, logs and dashboards pulled from the connected GA4 account - stays with the customer, who is also made responsible for everything collected from their own end users and for their own GDPR compliance. GAfix states it exercises no control over what Google Analytics transmits and processes it as-is, without modification or validation. The homepage goes further and claims nothing is stored, accessed or retained. The privacy policy nonetheless designates the company as a GDPR data controller, which sits awkwardly with that read-only framing.
Reuse rights
Nothing in the terms restricts what the customer may do with their own analytics data: what reaches GAfix is data the customer already owns and has authorised Google Analytics to collect, so it can be reused freely, for any purpose, without asking the vendor. The audit output is explicitly meant to travel - the Excel report of a Pro audit is sold on the promise that it can be shared with teammates, developers or clients and kept as documentation. On the vendor's side, the privacy policy permits personal data to be used to deliver and supervise the service, resolve technical issues, personalise the experience, detect fraud, meet legal obligations and produce analytics, reports and dashboards, and to improve the site for current and future users. Sharing is allowed with service providers, affiliates, business partners, and with anyone else on the user's consent. Personal information is not sold or traded without consent, but the policy reserves the right to pass non-identifiable visitor information to other parties for marketing or advertising.
Data retention & training
Hosting summary
GAfix states it is fully hosted on Amazon Web Services with a serverless architecture, and names AWS Lambda and Amazon S3 for processing and audit logs. No hosting country and no region are named anywhere on the site: there is no data residency commitment, no region selection and no mention of standard contractual clauses. The privacy policy adds that information is processed at the company's operating offices and wherever the parties involved are located, so it may be transferred to and held outside your own state, province or country, under data protection laws that differ from yours. The publisher, NeenOpal Inc., is a Delaware corporation with its principal place of business in Newark, New Jersey, and disputes are heard in New Jersey, so United States jurisdiction is the reasonable default reading. The domain itself resolves behind Cloudflare on an anycast address, which tells you nothing about where the data actually sits. The AWS Marketplace page claims alignment with ISO 27001:2022 and SOC 2 standards, but publishes no attestation.
Things to keep in mind
Risks and trade-offs to weigh before adopting GAfix.
- The homepage promises that nothing is saved, copied or reused, while the privacy policy allows retention, use for service improvement and sharing with providers, affiliates and business partners - read the policy, not the banner
- The company designates itself a GDPR data controller although the service is sold as a read-only auditor, and no data processing agreement or subprocessor list is published, which is a hard stop for some European buyers
- ISO 27001:2022 and SOC 2 are mentioned as an alignment on the AWS Marketplace page only, with no attestation and no dedicated trust or security page
- The terms of use restrict the service to personal or non-commercial purposes, which flatly contradicts the B2B positioning used everywhere else on the site
- Fees already invoiced are never refunded, subscriptions renew automatically, and a purchased Pro audit cannot be re-run without buying it again
- A green health score can breed false confidence: 18 or even 50 automated checkpoints are not a full analytics review, and they say nothing about whether your measurement plan matches your business questions
- The headline figures used across the site - 30% better data accuracy, 12X faster audits, 18% better ROI - come with no published methodology or sample
Setup & Integrations
Technical difficulty
Very low to get started. There is nothing to install, no script to place and no code to change. The only technical step is granting GAfix read access to the GA4 property from your Google Analytics account; Google Tag Manager requires nothing at all, since the container is read from publicly available data. The site states that no technical setup or coding knowledge is needed, and an audit runs with a single click. The difficulty moves downstream: acting on the recommendations means editing tags, triggers and events, which does require container access and real tracking skills.

Should you pick GAfix?
GAfix does one thing and states its boundaries clearly: it audits a Google Analytics 4 property and its Google Tag Manager container, and it tells you what is broken. That narrow scope is a strength. The checks are specific rather than generic, the read-only model removes most of the friction of letting a vendor near your analytics, and the GTM side needs no container access at all, which is unusual and welcome.
The free tier is the right way to judge it. Eighteen real checkpoints on a single audit is enough to see whether GAfix finds anything you did not already know, before spending USD 49 on a Pro audit. Buying audits one at a time rather than subscribing suits the way most teams actually work: you audit after a migration, a replatform or a quarter of suspicious numbers, not every week.
Three reservations deserve attention before committing. First, the documentation is not tidy: the pricing page and the help centre disagree on the price of the bundle and on the export format, and the pricing page still carries template blocks belonging to another product. Second, the privacy story has two voices - a homepage that promises nothing is stored or reused, and a privacy policy that reserves retention, sharing with partners and use for service improvement. Third, there is no data processing agreement, no subprocessor list, and the ISO 27001:2022 and SOC 2 references appear only as an alignment claim on the AWS Marketplace page, with no attestation behind them.
For a marketer or agency that needs a fast, explainable second opinion on a GA4 setup, GAfix is worth the free audit and probably the paid one. For a regulated buyer with a procurement checklist, the legal paperwork is not there yet.
