SEAL Metrics

846-byte first-party cookieless pixel
Install a tiny first-party script on your domain that logs pageviews without cookies, localStorage, or fingerprinting. Designed so ad blockers that target third-party analytics domains hit less often. Benefit: fuller traffic capture for teams stuck with consent-gated tags; trade-off: aggregate and channel metrics rather than person-level journey stitching.
Last-click revenue and ROAS attribution
Attributes conversions and revenue to channels, campaigns, and landing pages with last-click models the vendor positions as CRM-alignable. Built for eCommerce and hospitality media decisions—not generic pageview vanity charts. Limits: not a full multi-touch marketing mix model out of the box; validate against your CRM as the case studies do.
Real-time promo and campaign dashboards
Live views of revenue, channels, campaigns, and products during Promo Days so media teams can reallocate spend the same day. Suited to peak-load retail calendars. Constraint: value depends on tagging microconversions and keeping UTM hygiene; not a substitute for warehouse-grade BI alone.
LENS private AI on full capture
Optional LENS layer answers growth, risk, and wasted-spend questions in plain language against SealMetrics data (vendor states exclusive private AI on Enterprise tiers). Useful when analysts are scarce. Caveat: AI outputs are assistive—confirm high-stakes budget cuts against raw reports and offline finance data.
MCP and AI-assisted provisioning
Hosted MCP endpoint and docs let teams spin up accounts, pixels, and reports from AI coding assistants instead of a pure UI-only onboarding path. Speeds evaluation for engineering-heavy stacks. Still SaaS-only—there is no self-hosted SEAL Metrics server to run in your VPC.
EU Dublin storage with exports
Vendor documents processing and backups in Dublin, Ireland, with TLS 1.3, AES-256 at rest, and roughly 24-month analytics retention. API and BigQuery-style exports support dual-running with GA4. Hosting operator is described generically as an EU data center; Cloudflare sits on the transit path only.

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: SEAL Metrics vs Swetrix
Assurance & compliance	SEAL Metrics	Swetrix
Independent security / no-logs audit	Not found Vendor mentions regular security audits and independent legal audits; no public third-party audit PDF found on site/docs.	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 Data location docs list ISO 27001 as planned, not certified.	Not found No public ISO 27001 certification claim found on primary pages.
SOC 2 / SOC 3	Partial Vendor docs list SOC 2 Type II as in progress — not a completed public report.	Not found No public SOC 2/3 report found.
GDPR / EU data protection	Vendor claimed Spanish entity; cookieless architecture; EEA processing claims; DPA published. Legal conclusion remains for counsel.	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; analytics at rest in Dublin. Cloudflare (US group) processes TLS transit at EU edge. 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 Public DPA page; vendor states standard DPA with every plan, custom on Enterprise.	Vendor claimed Public DPA at swetrix.com/dpa incorporated by Terms; acceptance by use of Service; signed copy on request.
EU AI Act	Not applicable Core product is measurement analytics; optional LENS private AI is a feature—confirm classification if heavily relied on for automated decisions.	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: SEAL Metrics vs Swetrix
Considerations & known limitations	SEAL Metrics	Swetrix
US-group edge subprocessor (Cloudflare)	Medium Even with Dublin storage, Cloudflare sits on encrypted traffic. Procurement that bans any US-group vendor in the path will need a written exception or alternative edge posture.	Not listed
ISO/SOC not fully certified yet	Medium SOC 2 in progress and ISO planned per vendor docs. Enterprise security questionnaires may block until reports are available under NDA.	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.
Consentless claim is architectural, not a warranty	Medium Vendor argues no personal data / no cookies so analytics need no banner. Other scripts on the same site and national guidance still matter—get DPO sign-off.	Not listed
SaaS-only, proprietary pipeline	Low No self-host path. Mitigate with API/BigQuery export and dual-running with GA4 during evaluation.	Not listed
Hosting operator not named	Low Docs say EU data center in Dublin without naming the cloud or colo operator. Ask for the concrete provider in the TPSR pack.	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

SEAL Metrics

Best fit when

European eCommerce, DTC, and hospitality brands measuring paid media ROAS against incomplete consent-gated analytics
Marketing ops and agencies that need a single channel revenue source of truth finance can challenge less often
Teams that want side-by-side GA4 calibration without migrating off Google Ads tooling immediately
DPOs and CISOs evaluating analytics that claim no cookies, no fingerprinting, and EEA-only storage of analytics data
Stacks that prefer SaaS plus API/BigQuery export over running Matomo themselves

Poor fit when

Organizations that require self-hosted or open-source analytics under their own admin control
Product teams needing session replay, heatmaps, or deep multi-touch product analytics (Heap/FullStory class)
Buyers that will not accept SaaS until ISO 27001 or SOC 2 Type II is fully certified and publicly evidenced
Hobby sites and blogs that only need lightweight open-source pageview analytics

Consider instead when

When: You need open-source or self-hosted cookieless analytics
Consider: Plausible Analytics (self-host Community Edition) or Matomo
SEAL Metrics is SaaS-only with no public source license.
When: You want simple privacy-first page analytics without eCommerce ROAS tooling
Consider: Simple Analytics or Pirsch Analytics
Lighter EU privacy analytics peers; less paid-media attribution depth.
When: You need managed Matomo with Swiss hosting or enterprise on-prem options
Consider: Friendly Analytics
Matomo ecosystem plugins and heatmaps vs SealMetrics proprietary ROAS focus.
When: You need Google Ads-native reporting and free-tier product analytics breadth
Consider: Google Analytics 4
Different sovereignty and consent trade-offs; often kept alongside SealMetrics.

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.

Open questions for due diligence

SEAL Metrics

What is the exact legal entity name (e.g. S.L.) and registered address for contracts?
Which Dublin operator hosts app/DB/backups (name on the infrastructure questionnaire)?
Current status and availability date of SOC 2 Type II report and ISO 27001 certification?
Does any account data, billing, or support channel leave the EEA (email, payments, CRM)?
For LENS AI: training data isolation guarantees and EU AI Act role for customer use cases?

Swetrix

Can Enterprise contracts exclude or replace Sentry (and other US-group subprocessors) for End User data paths?
Are ISO 27001, SOC 2, or pen-test summaries available under NDA?
What is the exact backup/DR location topology beyond “secure backups” wording on the DPA?
Which Cloud-only features remain permanently out of CE versus delayed open-source release?
For session replay at your traffic volumes, what retention defaults and export/delete SLAs apply on your plan?
