Sitesights

Germany· Web Analytics

Needs review

Shortlist Sitesights when you need German-operated cookieless web analytics with real-time dashboards, funnels, page flow, and a server-side API—especially agencies and SaaS teams that want Hetzner Germany hosting claims without running Matomo. Skip when you need public ISO/SOC audits, long-term visitor identity, session replay, or a fully published subprocessor pack; consider Plausible Analytics or self-hosted Matomo instead.

Stormly

Netherlands· Web Analytics

Needs review

Shortlist Stormly when you need Dutch-contracted, e-commerce-first product analytics: SKU-aware report packs, Shopify/Adobe-oriented setup, inbox-style AI anomaly narratives, and a public DPA. Skip when you need cookieless privacy web stats only (consider Plausible, Simple Analytics, or Pirsch), open-source self-hosting, verified ISO/SOC on a public cert page, or a subprocessor chain free of US-group cloud and Azure OpenAI.

Sitesights

Cookieless 48-hour rotating session hash
Standard tracking does not set cookies. Sitesights generates a server-side salted hash from IP, User-Agent, and site id with a salt that rotates every 48 hours, so long-term cross-day visitor re-identification is intentionally broken. Useful when teams want essential traffic metrics without a cookie-consent banner solely for analytics—confirm legal basis with counsel for your jurisdiction and data fields (including geo).
Sub-1 KB client script plus WordPress and Shopify plugins
Drop-in client snippet marketed as under 1 KB, with official WordPress and Shopify integration paths for non-engineers. Fits marketing sites and stores that need quick instrumentation without a heavy tag manager stack.
Server-side REST API with C# and Node libraries
Send page views and events from your backend with API-key auth so ad blockers cannot strip the beacon. MIT-licensed C# and Node.js libraries on GitHub speed integration; keep API keys off the client. Preferred path for accuracy-critical SaaS and app backends.
Real-time overview with campaign and device filters
Live dashboard for visitors, pageviews, and sessions with advanced filters, UTM/campaign views, geo, browser, OS, screen size, and daytime patterns. Aimed at operators who want essential marketing analytics in one place rather than a full product-analytics suite.
Custom funnels and page-flow journey maps
Build multi-step funnels and visual page-flow maps to see entry paths, routes, and exits. Helps conversion and UX work without session replay. Depth is journey-oriented, not identity-graph product analytics.
Multi-project workspaces with roles for agencies
Group sites and apps into projects, assign roles/permissions, and invite clients or teammates. Marketing materials reference high ceilings for team seats and properties on paid plans—verify current limits on the official pricing page.

Stormly

AI agent for trends, anomalies, and root-cause style digs
Stormly positions an AI agent that watches connected e-commerce data for trends and anomalies (for example conversion drops or product spikes), then delivers plain-language findings—often to the inbox—with root-cause style exploration for questions like mobile conversion drops or regional return spikes. AI assistant access is plan-dependent; the public DPA documents Azure OpenAI (Microsoft) handling of assistant queries with a 30-day retention window and property stripping rules. Best for merchandising and growth leads who want narrative answers without waiting on a data team.
SKU-aware e-commerce report library (plus custom builds)
Ready reports target commerce questions: New Arrivals Performance (early SKU winners/laggards), Unviewed & Unsold Products, cart abandonment and revenue contribution by product/category, Conversion Journey and funnels by device/region, A/B test insights, Aha Moment Discovery, cross-selling analysis, and broader library items (retention, CLV, forecasting, SQL report, and more). Vendor materials state custom reports are included without a separate fee when a needed view is missing—useful for mid-market retailers that outgrow generic event charts.
Shopify, Adobe Commerce, Segment, and GTM-oriented connections
Homepage setup emphasizes linking Shopify, Adobe Commerce, or Segment quickly, with Google Tag Manager also listed among integrations. The DPA describes additional programmatic paths (JS library, import, custom endpoints, third-party sources). Fits stores already on common commerce stacks; teams on exotic storefronts should validate event coverage and product-feed depth in a pilot before replacing an existing analytics stack.
End-user tracking with IP anonymization defaults
Per the DPA, IP addresses for end-user analytics are not stored in full: the last octet is removed and geo/timezone are derived from the anonymized value. Web integrations automatically capture first-party cookie user ids, page/referrer/UTM context, and device metadata; app properties depend on client or CDP configuration. This is still full product analytics (not cookieless aggregate-only web stats)—clients remain responsible for consent banners and lawful basis for shopper tracking.
Public DPA, security architecture, and Dutch contracting
B2B buyers can download a Data Processing Agreement (effective 2023-09-06) and a Security Architecture page listing subprocessors, encryption expectations, backup retention (analytics backups up to six months), and logical tenant isolation. Contracts and DPA are governed by Dutch law with Amsterdam courts. Useful for EU procurement packages—but US-group subprocessors (AWS, Vultr, Azure OpenAI) still require transfer and CLOUD Act diligence.

Assurance & compliance: Sitesights vs Stormly
Assurance & compliance	Sitesights	Stormly
Independent security / no-logs audit	Not found No public third-party security or no-logs audit PDF located on the official site or docs.	Not found Security Architecture describes encryption, monitoring, isolation, and vulnerability contact (security@stormly.com); no public third-party audit PDF found.
ISO 27001	Not found No public ISO 27001 certificate found on official pages.	Not found No public ISO 27001 certificate located on official legal/security pages reviewed.
SOC 2 / SOC 3	Not found No public SOC 2/3 report found on official pages.	Not found No public SOC 2/3 report located on official pages reviewed.
GDPR / EU data protection	Vendor claimed German controller (Drude, Grossert GbR); cookieless hashing and EU hosting claims in docs/privacy. Confirm DPA and legal basis for IP/geo with counsel.	Vendor claimed NL entity; public privacy policy and DPA (GDPR-oriented); IP last-octet anonymization for end-user analytics; SCCs language for restricted transfers in DPA.
US CLOUD Act exposure (indicative)	Partial EU entity / no known US parent; product hosting claimed on Hetzner Germany. Marketing site lists Cloudflare (US); payments via Paddle; full SaaS subprocessor list not public. Indicative only—not legal advice.	Partial EU entity / no known US parent, but public client subprocessors include AWS, Vultr, and Microsoft Azure OpenAI (US-group companies). Account path historically also lists Amazon SES and Stripe. Residency claims do not remove US-group legal exposure. Indicative only—not legal advice.
Data processing agreement (B2B)	Not found No standalone public DPA download found during research; request under contract for B2B processing.	Vendor claimed Downloadable DPA PDF linked from stormly.com/dpa (effective 6 September 2023); audit rights and subprocessor notice described; Security Architecture lists subprocessors.
EU AI Act	Not applicable Web analytics product; not marketed as an AI system under the EU AI Act.	Partial Product includes an AI assistant via Azure OpenAI; not positioned as a high-risk AI system marketing claim. Buyers should map AI assistant use to their own AI Act / internal AI policy—vendor does not publish a full AI Act conformity package on the pages reviewed.

Considerations & known limitations: Sitesights vs Stormly
Considerations & known limitations	Sitesights	Stormly
No public independent security audit	Medium ISO 27001, SOC 2, and third-party security audits were not found on public pages. Enterprises may need to commission questionnaires or wait for vendor artifacts under NDA.	Not listed
Incomplete public subprocessor list	Medium Hetzner (product) and Cloudflare (marketing site) are documented; backups, email, support, and monitoring vendors for the SaaS are not fully listed. Ask for a current subprocessor annex.	Not listed
US-group CDN on marketing site	Low Privacy policy lists Cloudflare Inc. (US) for the public website CDN. Separate from claimed Hetzner product data path, but relevant to overall vendor surface area.	Not listed
48-hour hash limits long-term visitor analytics	Low By design, the rotating salt prevents durable cross-day visitor recognition. Teams needing retention cohorts or multi-week funnels by person must model events differently or choose product-analytics tools.	Not listed
On-premise availability is marketing-only detail	Low About page claims on-prem hosting; docs do not provide a self-serve install guide. Treat as sales-assisted until scope is confirmed in writing.	Not listed
US-group cloud and AI subprocessors	Not listed	Medium Despite Dutch HQ and EU residency marketing, client data paths publicly include AWS, Vultr, and Microsoft Azure OpenAI. Transfer tooling (SCCs) and encryption of backups are documented, but CLOUD Act / US legal process risk remains a diligence item for sovereignty-sensitive buyers.
No public ISO/SOC or independent audit	Not listed	Medium Enterprise security questionnaires may stall without ISO 27001/SOC 2 packs. DPA offers information/audit rights—plan time for NDA evidence requests.
Azure OpenAI retains assistant context 30 days	Not listed	Medium AI queries and aggregate report results are stored on Microsoft Azure OpenAI for 30 days per DPA. Property stripping reduces some identifiers, but misconfigured event properties could still expose sensitive content—govern AI use and property hygiene.
Controller privacy policy vs security architecture drift	Not listed	Low Privacy policy (controller, effective 2019) still emphasizes Vultr USA wording in places, while Security Architecture (client data) lists Hetzner/AWS/Vultr/Azure. Ask for a single current subprocessor and region matrix at contract time.
Not a privacy web-analytics substitute	Not listed	Low Full product analytics with cookies/identifiers for web integrations—not a cookieless aggregate counter. Consent UX remains on the client.

Fit

Sitesights

Best fit when

EU teams replacing GA4 with cookieless SaaS and wanting funnels/page-flow beyond a bare traffic counter
Agencies and freelancers managing many client sites with projects and role-based invites
Engineering-led installs that prefer server-side pageview/event ingestion against ad blockers
WordPress or Shopify properties that want official plugin paths plus a light client script
Orgs that value a German GbR legal entity and Hetzner Germany hosting claims over US multi-region analytics

Poor fit when

Product analytics requiring long-term user identity, cross-device stitching, or CDP-style profiles (48h hash by design)
Buyers who need public ISO 27001, SOC 2, or independent audit PDFs before shortlist
Teams that require self-serve open-source self-host as the primary deployment (on-prem only claimed, not documented as OSS)
UX research needs for heatmaps or session replay
Procurement that requires a complete public subprocessor list without an NDA conversation

Consider instead when

When: You want a minimal EU cookieless SaaS or a well-known self-host option
Consider: Plausible Analytics
Simpler metric set; strong self-host story. Sitesights markets deeper funnels/page-flow and multi-project agency features.
When: You need full self-host control, on-prem by default, or mature open-source governance
Consider: Matomo (self-hosted)
Heavier stack, deeper feature surface, and you operate the data plane yourself.
When: You need identity-rich product analytics, retention cohorts, or event warehouses
Consider: Mixpanel or similar product-analytics platforms
Different category—Sitesights is website/app growth analytics, not a full product analytics suite.
When: You need heatmaps, recordings, or UX feedback loops
Consider: Hotjar, Microsoft Clarity, or EU UX-analytics tools
Sitesights focuses on traffic, events, funnels, and flows—not session replay.

Stormly

Best fit when

Merchandising, product, UX, and growth teams on Shopify or Adobe Commerce who need SKU, cart, and assortment analytics without a dedicated data science org
Retail brands that want ready e-commerce report templates (new arrivals, unviewed/unsold, funnels, A/B, aha moments) plus vendor-built custom reports
EU buyers who want a Dutch legal entity, Amsterdam courts, and a downloadable DPA/Security Architecture package
Teams that value AI-generated trend/anomaly narratives delivered to the inbox more than building every chart from a blank event schema
Stacks already using Segment or Google Tag Manager as the event pipe into analytics

Poor fit when

Publishers or marketing sites that only need lightweight privacy-friendly page analytics (not product/SKU depth)
Orgs that require open-source self-hosting or full control of a private analytics warehouse as the default
Procurement policies that forbid US-group subprocessors (AWS, Vultr, Microsoft Azure OpenAI) even when EU regions are claimed
Assurance programs that require public ISO 27001/SOC 2 evidence before pilot (not found on vendor pages reviewed)
Companies operating blockchain products/services—restricted by Stormly’s terms

Consider instead when

When: You only need privacy-oriented website metrics (pageviews, sources) rather than SKU-level product analytics
Consider: Plausible Analytics, Simple Analytics, or Pirsch Analytics
EU web-analytics peers; different category from e-commerce product analytics
When: You need deep general-purpose product analytics, large ecosystem, and mature multi-product SaaS event modeling
Consider: Mixpanel or Amplitude
US incumbents; stronger breadth, different jurisdiction and commercial model
When: You primarily need free/universal marketing acquisition reporting already embedded in the stack
Consider: Google Analytics (incumbent) or dual-run GA for marketing + Stormly for product/merch
GA is not SKU-first product analytics; Stormly is not a GA replacement for every report

Open questions for due diligence

Sitesights

Will the vendor sign a B2B DPA and provide a complete subprocessor list (backups, email, support, monitoring)?
Is the Hetzner Germany residency contractual for all analytics tenant data, including DR/backups?
What is the formal on-premise offering (SLA, update model, supported regions) versus SaaS-only?
Are any ISO 27001 / SOC 2 / penetration-test reports available under NDA?
How should geolocation fields and IP hashing be assessed under your counsel's GDPR legal-basis analysis?

Stormly

Can Stormly provide a current region map (which data classes live on Hetzner vs Vultr vs AWS) under NDA for our DPIA?
Are ISO 27001, SOC 2, or penetration-test summaries available on request for enterprise security review?
Which event properties from our Shopify/Adobe feed are excluded from Azure OpenAI prompts by default in our tenant?
Do custom report builds and SQL access sit only on the custom tier, and what SLAs apply?
Has the 2019 controller privacy policy been superseded for hosting wording relative to the Security Architecture list?
