Matomo by Stackhero

Dedicated bare-metal Matomo instance
Each customer gets an isolated VM on Stackhero’s own bare-metal cloud (Stackhero DC OS), not shared multi-tenant Matomo. Local disks and included Redis are positioned for high IOPS and heavy traffic—fit teams that outgrow noisy-neighbor shared analytics clouds.
Unlimited sites, members, segments, and goals until capacity
Stackhero does not meter websites, team seats, segments, or goals as product SKUs; you scale by instance size (published up to 16 vCPUs / 64 GB RAM). Retention is limited by disk, not a fixed product TTL—plan storage for long history.
One-click Matomo updates and managed ops (no SSH)
Stackhero delivers Matomo updates for dashboard application; firewall IP rules are customer-configurable. SSH is intentionally unavailable on the managed service—good for reduced surface area, poor fit if you need custom OS packages.
Custom domain, GeoIP2, and dedicated notification email
Point matomo.yourdomain.com with TLS 1.3/ECDSA, ship visitor location via bundled GeoIP2, and send unlimited Matomo reports/alerts through a per-instance email path—reduces glue work after first deploy.
Atomic encrypted daily backups (EU vault)
24-hour atomic image backups (plus event-driven backups on upgrades) are validated, then encrypted (OpenPGP ECDH/Curve25519) and retained up to three months. Vendor FAQ states backups are stored in the EU even when regions differ—confirm dual-region implications for US instances.
Hourly billing with EU or US region choice
Spin services up/down with hourly charging and a single monthly invoice; free trial without payment method. Choose European (France) or USA placement at create time—region is a first-class control for residency, not a hidden default.

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.

Assurance & compliance: Matomo by Stackhero vs SEAL Metrics
Assurance & compliance	Matomo by Stackhero	SEAL Metrics
Independent security / no-logs audit	Not found ISO 27001 and bug-bounty openness claimed; no public independent no-logs audit report specific to analytics found.	Not found Vendor mentions regular security audits and independent legal audits; no public third-party audit PDF found on site/docs.
ISO 27001	Vendor claimed Vendor publishes ISO/IEC 27001:2022 certificate #254338 from the British Assessment Bureau (PDF). Not re-verified against the issuer’s public register in this draft.	Not found Data location docs list ISO 27001 as planned, not certified.
SOC 2 / SOC 3	Not found No SOC 2/3 claim found on certifications/privacy/GDPR pages reviewed.	Partial Vendor docs list SOC 2 Type II as in progress — not a completed public report.
GDPR / EU data protection	Vendor claimed French entity; public GDPR & DPA page; customer controller / Stackhero processor model; EU region option for service data.	Vendor claimed Spanish entity; cookieless architecture; EEA processing claims; DPA published. Legal conclusion remains for counsel.
US CLOUD Act exposure (indicative)	Partial French entity, no known US parent, non-hyperscaler bare-metal hosting claimed. Medium/partial because USA is a first-class hosting region; EU-only only when the customer creates the service in Europe. Backups stated as EU-stored. Not legal advice.	Partial EU entity / no known US parent; analytics at rest in Dublin. Cloudflare (US group) processes TLS transit at EU edge. Not legal advice.
Data processing agreement (B2B)	Vendor claimed DPA applies automatically with Terms of service; PDF downloadable from the GDPR & DPA page.	Vendor claimed Public DPA page; vendor states standard DPA with every plan, custom on Enterprise.
EU AI Act	Not applicable Web analytics hosting; not positioned as an AI system product.	Not applicable Core product is measurement analytics; optional LENS private AI is a feature—confirm classification if heavily relied on for automated decisions.

Considerations & known limitations: Matomo by Stackhero vs SEAL Metrics
Considerations & known limitations	Matomo by Stackhero	SEAL Metrics
Optional US hosting region	Medium Platform offers USA placement alongside France/EU. Mis-selected region or unclear contract language can put visitor analytics outside the EU. Procurements that require EU-only must pin region at create time and in the order form.	Not listed
EU backups when primary is US	Medium FAQ states backups are stored in the EU. If an instance runs in the USA, confirm whether visitor data is dual-homed (US primary + EU backup) and how that affects DPIA and transfer tools.	Not listed
No SSH / managed-only host	Low Cannot install arbitrary system software or agents; support hours stated as CET office hours for basic platform support—not full Matomo application consulting.	Not listed
Limited named subprocessor list	Medium Privacy policy mentions third-party tools and a payment processor without a detailed public subprocessor register. Request the annex in diligence if procurement requires named processors.	Not listed
ISO certificate vendor-published	Low ISO 27001:2022 is claimed with a public PDF and BAB certificate number; validate scope, sites, and validity dates with the certification body before treating it as verified.	Not listed
Matomo privacy configuration is yours	Low Hosting in the EU does not auto-configure consent, IP anonymization, or cookieless modes. Controllers remain responsible for Matomo GDPR tooling and site policy.	Not listed
US-group edge subprocessor (Cloudflare)	Not listed	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.
ISO/SOC not fully certified yet	Not listed	Medium SOC 2 in progress and ISO planned per vendor docs. Enterprise security questionnaires may block until reports are available under NDA.
Consentless claim is architectural, not a warranty	Not listed	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.
SaaS-only, proprietary pipeline	Not listed	Low No self-host path. Mitigate with API/BigQuery export and dual-running with GA4 during evaluation.
Hosting operator not named	Not listed	Low Docs say EU data center in Dublin without naming the cloud or colo operator. Ask for the concrete provider in the TPSR pack.

Fit

Matomo by Stackhero

Best fit when

Teams that want Matomo’s full analytics/admin surface without running OS or Matomo upgrades themselves
Buyers who prefer a dedicated VM and capacity-based limits over multi-tenant hit metering
Orgs consolidating Matomo with other Stackhero-managed open-source services under one French operator
Projects that need hourly elasticity and the ability to stop billing with one click
Controllers who will configure Matomo privacy features themselves and want a signed/automatic DPA plus ISO 27001 claims

Poor fit when

Requirements that forbid any US hosting option or dual-region backup stories—platform publicly offers USA regions
Teams that need SSH, custom kernels, or non-Matomo system agents on the host
Buyers seeking only a lightweight cookieless pageview product (Plausible-class tools are simpler)
Organizations that must self-host inside their own cloud account with no third-party PaaS operator
Use cases needing a named public subprocessor register beyond Stackhero’s high-level privacy/GDPR pages

Consider instead when

When: You want Swiss Matomo-as-a-Service with cookieless defaults and CH product hosts
Consider: Friendly Analytics
Different operator, residency story, and privacy defaults; still Matomo-based.
When: You need enterprise analytics packaging beyond plain managed Matomo
Consider: Piwik PRO
Compare modules, contracts, and hosting regions independently.
When: You only need a minimal open-source-friendly counter with simple SaaS UX
Consider: Plausible Analytics
Far less Matomo depth; different product surface.
When: You require full root control and in-house residency guarantees
Consider: Self-hosted Matomo on your own EU IaaS
Maximum control; you own updates, backups, and hardening.

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.
