## Key Differentiators

- **No installation, no SDK, no snippet** — AssertionHub works externally via a browser recorder. Nothing is added to the monitored website's codebase.
- **No access to analytics accounts** — No GA4 property access, no GTM container access, no admin permissions required. Works entirely from the outside.
- **Integrates on top of your existing stack** — Works with whatever analytics setup is already live: GA4, GTM, Meta Pixel, Adobe Web SDK, etc. No migration, no changes.
- **No-code** — Non-technical users (analysts, marketers, QA) can create and maintain complex test scenarios without writing code.
- **Consent mode awareness** — Validates Google Consent Mode v1/v2 state for every captured event, not just whether a tag fired.
- **AI-assisted recording** — Interactions described in plain text; AI generates selectors during replay, so tests survive UI changes.
- **Affordable** — Free plan available; paid plans from EUR 49/month vs enterprise competitors at USD 2,500+/month.
