AI-driven GA4/GTM implementation from a single site scan.
Drop a URL, let the AI agent map your site and consent state, have the AI model draft the manifest, then approve, deploy to GTM, and validate automatically with guarded background jobs.
14-day free trial • No credit card required
Scan any site in seconds and map the full customer journey.
Draft compliant GA4 + GTM events with pre-built governance.
Validate every tag in production with autonomous QA scripts.
Ship analytics without the churn: consent-aware crawls, naming aligned to your conventions, and guarded GTM deploys with validation baked in.
No public ratings yet. We’ll publish verified metrics once customer pilots are live.

What we process and where it lives
Clear guardrails for analytics and legal buyers: read-only crawling, no PII capture, and predictable storage.
Data processed
Rendered DOM, consent signals, event metadata, and tag/trigger configurations needed to draft GA4/GTM manifests. No credentials or form inputs are collected; logs use our PII redactor before storage.
How scans run
Headless Playwright crawls run in read-only mode to observe structure and events. We do not mutate page state, submit forms, or inject tracking beyond the temporary crawler instrumentation required to measure events.
Where data is stored
Supabase (Postgres + object storage) in the ap-south-1 (Mumbai) region with encryption at rest and in transit. Data is retained only for crawl results, manifests, and QA reports. See our privacy policy.
Ship measurement without the mess
TagZen automates discovery, drafts governed specs, and keeps releases compliant before they ship.
Autonomous site scans
Playwright crawler maps DOM, dataLayer pushes, and consent signals while honoring robots and domain limits.
View detailsAI measurement plans
FastAPI agent builds GA4 events, GTM tags, confidence scores, and consent metadata for each workspace manifest.
View detailsManifest review & approvals
Accept, reject, or edit events in the dashboard diff; approvals emit deployment events with version history.
View detailsGTM deployment guardrails
Inngest GTM worker calls the AI deploy endpoint with per-workspace rate limits, retries, and error handling.
View detailsConsent-aware validation
Crawler `/validate` endpoint runs Playwright checks post-deploy and stores pass/fail reports with consent context.

Questions, answered
Everything you need to know before rolling out TagZen across your stack.
- You trigger /api/scan from the dashboard.
- Inngest queues the job and the Playwright crawler gathers DOM + consent signals.
- The AI service generates a GA4 manifest which appears in the review UI for approval.
- Connect your GTM credentials and approve the manifest.
- Inngest calls the FastAPI deploy endpoint with rate limits and retries.
- Deployments are logged in Supabase for auditing.
- The crawler detects consent frameworks and passes metadata to the AI service.
- Consent state is stored with each manifest so reviewers and validators can enforce region-specific rules.
- After deployment, an Inngest listener calls the crawler /validate endpoint.
- Playwright runs checks against your site and stores pass/fail reports and timestamps in Supabase.
- Billing flows through Dodo Payments.
- Plan names and limits are being finalized; contact us for access while pricing is confirmed.
- TODO: Confirm public pricing before launch.
- Yes. AI manifests are reviewed in the dashboard.
- You choose which events to accept or edit before triggering deployment to GTM.
