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.

Swetrix

Cookieless traffic analytics with hashed sessions
Lightweight script captures pageviews, referrers/UTMs, devices, and city-level geo without cookies or client-side storage. Per the Data Policy, IP and User-Agent are hashed in memory with a daily rotating salt; only a random session id is stored—so you get sessions without long-term cross-day visitor retention.
Funnels, custom events, and goals
Instrument signups, purchases, and other conversions as custom events; build multi-step funnels and goals in the dashboard. Useful for product and growth teams who need drop-off analysis without bolting on a second product-analytics SaaS.
Real-user performance and client error tracking
Records Web Performance API timings (TTFB, DNS, TLS, render, full page load) and optional JavaScript errors with stack/context by page and browser. Bridges marketing traffic views with engineering signals that pure pageview tools omit.
Opt-in Cloud session replays with privacy modes
Cloud projects can call startSessionReplay() to record DOM and interactions; default modes mask text/inputs. Replays are not created by ordinary pageviews—customers must enable them and own consent, masking, and page exclusions. Cloud-only versus Community Edition.
AGPLv3 open source with Docker self-host CE
Core platform is public on GitHub under GNU AGPLv3; Community Edition deploys via official Docker docs with MySQL, ClickHouse, and Redis. CE includes core analytics, events, sessions, funnels, performance, and errors—but not all Cloud extras (replays, some alerts/org/AI features).
Alerts, API, GA import, and team access
Configure alerts to email, Slack, Telegram, Discord, webhooks, or push; pull or push data via the API; import GA4 history; invite organisations with roles or share password-protected/public dashboards. Fits agencies and multi-site operators who outgrow single-user tools.

Assurance & compliance: Stormly vs Swetrix
Assurance & compliance	Stormly	Swetrix
Independent security / no-logs audit	Not found Security Architecture describes encryption, monitoring, isolation, and vulnerability contact (security@stormly.com); no public third-party audit PDF found.	Not found Searched marketing, DPA, privacy, and data policy; no public independent audit PDF located. Open-source code is available for review.
ISO 27001	Not found No public ISO 27001 certificate located on official legal/security pages reviewed.	Not found No public ISO 27001 certification claim found on primary pages.
SOC 2 / SOC 3	Not found No public SOC 2/3 report located on official pages reviewed.	Not found No public SOC 2/3 report found.
GDPR / EU data protection	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.	Vendor claimed UK company; public GDPR/PECR discussion in Data Policy; cookieless design with non-stored IPs for standard analytics; Hetzner DE hosting; public DPA. Optional replays may be personal data depending on configuration—customer assesses legal basis.
US CLOUD Act exposure (indicative)	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.	Partial No known US parent; primary analytics on Hetzner DE. Material exception: Sentry (US) processes End User error data per DPA; Privacy Policy also lists AWS and OpenRouter (US) for customer email/AI. Indicative medium exposure—not a clean bill. Not legal advice.
Data processing agreement (B2B)	Vendor claimed Downloadable DPA PDF linked from stormly.com/dpa (effective 6 September 2023); audit rights and subprocessor notice described; Security Architecture lists subprocessors.	Vendor claimed Public DPA at swetrix.com/dpa incorporated by Terms; acceptance by use of Service; signed copy on request.
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.	Not applicable Core product is web analytics, not an AI system. Optional Ask AI / OpenRouter is ancillary; confirm if your deployment enables it.

Considerations & known limitations: Stormly vs Swetrix
Considerations & known limitations	Stormly	Swetrix
US-group cloud and AI subprocessors	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.	Not listed
No public ISO/SOC or independent audit	Medium Enterprise security questionnaires may stall without ISO 27001/SOC 2 packs. DPA offers information/audit rights—plan time for NDA evidence requests.	Medium Assurance relies on first-party policies, Hetzner infrastructure claims, and open source. Enterprise questionnaires that hard-gate on certs will stall until materials are provided under NDA or produced.
Azure OpenAI retains assistant context 30 days	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.	Not listed
Controller privacy policy vs security architecture drift	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 listed
Not a privacy web-analytics substitute	Low Full product analytics with cookies/identifiers for web integrations—not a cookieless aggregate counter. Consent UX remains on the client.	Not listed
US-group subprocessors (Sentry, AWS, OpenRouter)	Not listed	Medium Primary analytics hosting is Hetzner DE, but Sentry (US) is an End User error-tracking sub-processor on the DPA, and AWS/OpenRouter appear for customer email/AI. Orgs with strict no-US-cloud rules need explicit acceptance or self-host CE to avoid those paths.
Session replay is opt-in and controller-owned	Not listed	Medium Cloud replays can capture DOM and inputs unless masked. Customers must enable startSessionReplay(), configure privacy modes/exclusions, and provide notices/consent where required—misconfiguration can reintroduce personal data risk that standard cookieless pageviews avoid.
Cloud vs Community Edition feature gap	Not listed	Low Self-host CE is free and covers core analytics, but replays and several Cloud growth/ops features are limited or Cloud-only. Budget and feature planning must not assume feature parity.
Daily salt rotation limits retention metrics	Not listed	Low Cookieless design deliberately prevents classic multi-day visitor retention. Teams that need that metric class need another product or consented identity.

Fit

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

Swetrix

Best fit when

SMEs, agencies, and product teams replacing GA4 who need cookieless traffic stats without a cookie banner driven only by analytics
Engineering-minded buyers who want error tracking and real-user performance in the same privacy-first dashboard as pageviews
Teams that may enable Cloud session replays later but can treat them as explicit opt-in with their own legal basis
Operators willing to run Docker Community Edition (MySQL/ClickHouse/Redis) when Cloud commercial terms or feature limits do not fit
Buyers who need a public B2B DPA, API access, GA4 import, and multi-channel alerts under a UK legal entity

Poor fit when

Enterprises that require published ISO 27001 / SOC 2 certificates or independent audit PDFs before shortlist
Policies that forbid any US-group subprocessors (Sentry is listed for End User error data; AWS/OpenRouter appear for customer services)
Use cases that depend on long-term cookie-based retention or cross-device identity graphs
Buyers who only want free hosted analytics with no paid Cloud tier and no self-host operations burden
Sites that will run session replays on sensitive flows without capacity to configure masking, exclusions, and consent

Consider instead when

When: You only need minimal cookieless pageviews/referrers with the smallest possible product surface
Consider: Plausible Analytics or Simple Analytics
Swetrix adds funnels, errors, RUM, and Cloud replays; peers stay closer to pure traffic analytics.
When: You need deep on-prem control, plugins, and mature enterprise self-host packaging
Consider: Matomo (self-host or managed EU hosts such as Matomo by Stackhero)
Heavier ops and optional cookies; stronger fit for large controlled deployments.
When: You must stay inside Google advertising measurement and free GA4 ecosystem tooling
Consider: Google Analytics
Trade privacy, consent, and transfer complexity for ads integration and zero software fee.
