Piwik PRO

ClickHouse-backed web & mobile analytics
Session-level web and app analytics with custom reports, funnels, user flows, multi-channel attribution, and calculated metrics. Vendor positions unsampled collection by default with optional sampling for extreme volumes, plus raw export via API, files, and BigQuery—aimed at teams that outgrew pre-aggregated MySQL-style tools.
Anonymous tracking when cookies are declined
Collect privacy-safe behavioral signals without identifiers when visitors refuse cookies or when you configure limited measurement modes. Marketing can still see channels and journeys; personal identifiers and full attribution wait for a valid lawful basis—useful under GDPR/ePrivacy friction.
Integrated Consent Manager and Tag Manager
Capture and store consent, drive tag firing from preferences, and handle visitor data requests in-product. Optional Cookie Information CMP and server-side tagging paths reduce the usual glue code between a separate CMP, GTM, and analytics.
Data Activation for real-time personalization
Segment audiences from live behavior and trigger on-site or outbound actions without exporting every event to a second CDP first. Suited to regulated marketers who want activation on first-party data they control.
Selectable cloud residency (Azure + Elastx)
Public cloud regions include Azure US, NL, DE, and HK plus Elastx Sweden; Enterprise private cloud spans 60+ Azure regions and Elastx. Business plan marketing highlights EU-operated Swedish hosting—pick region in procurement, not after go-live.
Regulated-industry packaging (GDPR tooling, HIPAA BAA path)
DPA available on Business signup; Enterprise adds private cloud, higher action volumes, SLAs, and HIPAA Business Associate Agreements for healthcare marketing analytics. Vendor also claims ISO 27001 and SOC 2—request current certificates in 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: Piwik PRO vs Swetrix
Assurance & compliance	Piwik PRO	Swetrix
Independent security / no-logs audit	Partial Vendor states regular external security audits and SOC 2/ISO programs; no public third-party no-logs-style audit PDF reviewed for this draft. Request reports under NDA.	Not found Searched marketing, DPA, privacy, and data policy; no public independent audit PDF located. Open-source code is available for review.
ISO 27001	Vendor claimed Asserted on privacy-security and platform pages; certificate not independently re-verified against a public registry for this entry.	Not found No public ISO 27001 certification claim found on primary pages.
SOC 2 / SOC 3	Vendor claimed Vendor claims SOC 2 (comparison content references type II) and SOC 2-certified infrastructure; obtain current report in diligence.	Not found No public SOC 2/3 report found.
HIPAA / BAA	Vendor claimed HIPAA-oriented offering with BAA on Enterprise path per vendor; not available on all plan tiers.	Not listed
GDPR / EU data protection	Vendor claimed EU legal entity, residency options, consent tooling, anonymization, and DPA. Compliance depends on customer configuration and purposes.	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 No known US parent (Polish SA). Medium exposure due to Microsoft Azure as public/private cloud subprocessor and optional US region; Elastx Sweden is EU-operated alternative. 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 Business DPA linked from Business plan signup (piwik.pro/business-dpa/); Enterprise contracts expand terms.	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 Analytics/activation platform; not marketed as an AI system provider. Customer AI use of exported data is out of product scope.	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: Piwik PRO vs Swetrix
Considerations & known limitations	Piwik PRO	Swetrix
US-group cloud (Azure) in hosting path	Medium Even with EU region selection, Azure introduces US-group infrastructure risk. Pin region, review SCCs/subprocessors, and escalate if policy forbids US cloud groups entirely.	Not listed
Closed source and no classic self-host	Medium Cannot independently audit full source or run fully air-gapped on customer iron. Private cloud still involves vendor-managed stack on Azure/Elastx.	Not listed
Certifications not independently verified here	Low ISO 27001, SOC 2, and HIPAA are vendor-claimed. Request certificates/reports and BAA text before treating them as assured.	Not listed
Paid plans only after Core sunset	Low Free Core has been discontinued; evaluation relies on trials and paid Business/Enterprise metering by actions/domains.	Not listed
Compliance depends on configuration	Medium Anonymous modes and CNIL exemption require correct setup and purpose limitation. Misconfiguration can recreate the same legal exposure teams left GA to avoid.	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.
No public ISO/SOC or third-party audit	Not listed	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.
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

Piwik PRO

Best fit when

Regulated marketing/analytics teams that want one suite for measurement, consent, tags, and activation under a Polish legal entity
Public sector and EU enterprises that need selectable EU residency (e.g. Elastx Sweden or Azure NL/DE) plus a formal B2B DPA
Healthcare digital teams evaluating HIPAA-aware analytics with a signed BAA on Enterprise
Organizations leaving GA4 primarily for residency, no vendor ad-network reuse, and anonymous pre-consent measurement options
Teams that need enterprise reporting depth (custom reports, funnels, flows, attribution) beyond lightweight privacy analytics

Poor fit when

Buyers who mandate fully self-hosted open-source analytics with no cloud hypervisor vendor
Sites that only need simple cookieless page analytics without tag management or activation
Teams that refuse any US-group infrastructure (Azure appears in public hosting options even when EU regions are chosen)
Orgs seeking a free forever analytics tier (Core plan sunset; paid Business/Enterprise only)

Consider instead when

When: You need open-source code and true on-premises control
Consider: Matomo (self-host) or Friendly Analytics / Matomo by Stackhero for managed Matomo
Piwik PRO is proprietary cloud/private-cloud only.
When: You want minimal, cookieless EU analytics without enterprise suite complexity
Consider: Plausible Analytics or Simple Analytics
Far smaller feature surface; no HIPAA/CDP-style activation packaging.
When: You need a German enterprise analytics vendor with long public-sector presence
Consider: etracker
Different product depth and packaging—compare consent tooling and activation needs.

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.
