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.

Offen Fair Web Analytics

  • Opt-in only collection with first-party cookies

    No analytics events are recorded until the visitor actively consents. Cookies are first-party and the tracker is meant to run on a same-site subdomain so third-party cookie restrictions and cross-site tracking models do not apply. Visitors who never opt in leave no usage trail—expect lower absolute volumes than cookieless tools that measure by default.

  • Browser-side end-to-end encryption of usage events

    Clients encrypt usage data before it leaves the browser; the server stores ciphertext and cannot decrypt events alone. Only the visitor (via their cookie) and the matching operator account can open that visitor's data in the Auditorium. Practical impact: a compromised database or overly broad ops access does not yield plaintext browsing histories the way a typical self-hosted analytics DB would.

  • Auditorium for both operators and visitors

    Operators see aggregates across pages where the installation is active (unique users/sessions, top pages, filters). Each opted-in visitor can open the same style of UI for their own data only, with plain-language metric explanations, and can delete data or fully opt out later. This is the fair design point: measurement is not a one-way glass.

  • Essential metrics without IP or User-Agent capture

    Dashboards cover real-time activity, page views, unique users and sessions, bounce rate, returning users, top pages, referrers, UTM campaign/source, landing and exit pages, weekly retention, and load time. Location is country-level from timezone mapping; mobile share uses orientation capability—not IP geolocation or UA parsing. No heatmaps, session replay, or warehouse-grade product analytics.

  • Lightweight self-host: binary, Docker, SQLite or SQL

    Production installs use a single binary (Linux/Windows/macOS) or the offen/offen image; docs also cover Heroku, Uberspace, and YunoHost. Default store is SQLite; MySQL and Postgres are supported. AutoTLS can request Let's Encrypt certificates. Config is environment variables or offen.env. You own uptime, backups, SMTP for password reset, and the subdomain layout.

  • Multi-site accounts, teams, and short retention

    One installation can cover multiple websites with shared team access. Default retention is six months with automatic deletion; operators can shorten retention (e.g. 12 weeks, 30 days, 7 days) knowing shorter values purge older events on startup. Consent banner appearance is customizable; UI locales include EN, DE, FR, ES, PT, and VI.

Assurance & compliance: Matomo by Stackhero vs Offen Fair Web Analytics
Assurance & complianceLogo: Matomo by StackheroMatomo by StackheroLogo: Offen Fair Web AnalyticsOffen Fair Web Analytics
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

No public third-party audit PDF found; coordinated disclosure via SECURITY.md email only.

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

No public ISO 27001 certification claim found on official site or docs.

SOC 2 / SOC 3
Not found

No SOC 2/3 claim found on certifications/privacy/GDPR pages reviewed.

Not found

No public SOC 2/3 report found.

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

EU authors; opt-in, data minimization (no IP/UA), visitor access/erasure, short default retention, Datensparsamkeit framing. Self-host means operator remains controller—confirm your legal basis and notice.

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

EuropeanStack assessment: no known US parent; product not delivered as US-hosted vendor SaaS. Operator-chosen infrastructure (including optional Heroku/US cloud) can still create CLOUD Act paths for stored ciphertext/metadata. Not legal advice.

Data processing agreement (B2B)
Vendor claimed

DPA applies automatically with Terms of service; PDF downloadable from the GDPR & DPA page.

Not applicable

No multi-tenant vendor analytics processing relationship documented; operator self-hosts and is typically controller. Custom development/support via offen.software is separate from a standard SaaS DPA.

EU AI Act
Not applicable

Web analytics hosting; not positioned as an AI system product.

Not applicable

Web analytics metrics product; not an AI system product.

Considerations & known limitations: Matomo by Stackhero vs Offen Fair Web Analytics
Considerations & known limitationsLogo: Matomo by StackheroMatomo by StackheroLogo: Offen Fair Web AnalyticsOffen Fair Web Analytics
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
Opt-in undercounts absolute trafficNot listed
High

Visitors who never consent generate no events. Growth and content KPIs will not match cookieless tools or GA-style default measurement—treat as design, not a misconfiguration.

You own uptime, backups, and secretsNot listed
Medium

No managed Offen cloud. Operators must run HTTPS/subdomain layout, set OFFEN_SECRET for stable sessions, configure SMTP for resets, and back up SQLite/SQL—plus avoid reverse proxies that log IPs if minimization is a goal.

E2E crypto is vendor-claimed architectureNot listed
Medium

Browser-side encryption and server inability to decrypt are core claims from project docs/README, not independently audited in public materials found. Security-sensitive orgs should review source or commission assessment.

Hosting choice reintroduces cloud jurisdictionNot listed
Medium

Self-host on US-group cloud or Heroku means CLOUD Act/subprocessor analysis shifts to your host even though Offen itself is Berlin-based OSS without a vendor SaaS region map.

No public ISO/SOC or audit packNot listed
Low

Procurement checklists that require vendor ISO 27001/SOC 2 will stall; evidence is open source and design docs, not cert registry entries.

Essential metrics onlyNot listed
Medium

No heatmaps, session replay, advanced funnels, or product-analytics warehouse features. Wrong tool if the shortlist criterion is UX research depth rather than fair traffic statistics.

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.

Offen Fair Web Analytics

Best fit when

  • Public-sector, media, NGO, or mission-driven sites that need visitor-visible transparency and strict opt-in
  • EU teams that must keep analytics off third-party trackers and can run a small always-on instance
  • Operators who want first-party subdomain cookies, CSP-aware embedding, and no IP/User-Agent collection
  • Organisations evaluating fair-processing design over maximum measurement coverage
  • Teams comfortable with SQLite or SQL self-host ops (binary or Docker) and publishing their own privacy notice

Poor fit when

  • Product or growth teams that require near-complete traffic measurement without consent friction
  • Needs for heatmaps, session replay, funnels, or ad-ecosystem attribution comparable to Hotjar/Mixpanel/GA
  • Buyers seeking a vendor-managed multi-tenant analytics cloud with SLAs and a signed vendor DPA as processor
  • Large enterprises that require public ISO 27001/SOC 2 or third-party security audit packs before shortlist

Consider instead when

  • When: You want privacy-oriented analytics with managed EU hosting and lower consent friction

    Consider: Plausible Analytics or Pirsch Analytics

    Typically optimised for simpler cookieless or low-friction models and hosted plans; less radical visitor Auditorium design than Offen.

  • When: You need EU hosted privacy analytics with operator support and less self-host burden

    Consider: Friendly Analytics

    European catalog peer oriented to hosted privacy analytics; compare consent model and feature depth to Offen’s opt-in + E2E approach.

  • When: You need deep product analytics, funnels, or session UX tooling rather than fair traffic metrics

    Consider: Hotjar, Mixpanel, or a full GA4 stack (with legal review)

    Different category: richer product/UX analytics, different jurisdiction and subprocessor profile.

Open questions for due diligence

Matomo by Stackhero

  • Will the order form and DPA annex permanently pin the Matomo instance to the EU (France) region with no US failover?
  • For US-region instances, what exact data is copied to EU backup vaults and under which transfer mechanism?
  • Who is the unnamed parent company referenced on the About page, and is there any US ownership or PE?
  • Can ISO 27001 certificate 254338 be validated on the British Assessment Bureau (or successor) public register for current scope/dates?
  • Which payment, support, and website analytics providers process Stackhero account data (named subprocessor list)?

Offen Fair Web Analytics

  • Will your traffic and KPI model tolerate opt-in-only measurement after a pilot on a non-critical property?
  • Where will you host the instance (EU on-prem/VPS vs US-group cloud), and who holds OFFEN_SECRET and DB backups?
  • Do procurement rules require third-party audits or ISO/SOC that Offen does not publish?
  • Do you need a signed vendor DPA as processor, or is controller-only self-host acceptable to counsel?
  • Is subdomain + CSP (script-src/frame-src + unsafe-inline styles for the banner) feasible on your main site?
