Pirsch Analytics

Cookie-free 24-hour visitor hashing
Recognizes visitors without cookies by hashing IP, User-Agent, date, and a per-site salt into a short ID. The vendor states IPs are not stored and cross-site linkage is blocked by the salt; sessions expire after 24 hours so long-term profiles are not built. Best for sites that want aggregate traffic metrics without a dedicated analytics cookie banner—confirm ePrivacy/TTDSG fit with counsel.
Server-side and script integrations
Instrument via JS snippet, CMS plugins (e.g. WordPress, Shopify, Webflow, Framer), or backend SDKs/API (Go library and other stacks). Server-side collection improves resilience when ad blockers strip client scripts. Tradeoff: backend integration costs more engineering time than a single script tag.
Funnels, events, goals, and tag segmentation
Goes past pageviews with custom events, conversion goals, multi-step funnels, session path exploration, outbound/download/404 tracking, and tags for A/B tests or channel segmentation. Webhooks and email reports push insights into existing tools. Some advanced metrics (e.g. custom event metrics, e-commerce revenue tracking) sit on higher commercial tiers—verify the live feature matrix.
Agency white-label and shared dashboards
Custom domains, themes, logos, and broader white-label options let agencies present analytics under their own brand. Public dashboards and unique access links support clients without full account sprawl; roles/teams scale collaboration. Strong fit for multi-client portfolios; less relevant for a single personal blog.
Migration imports, API, and unlimited retention (stated)
Import historical data from Google Analytics, Plausible, or Fathom; export CSV; use the REST API and SDKs for custom pipelines. Pricing docs state unlimited data retention across Standard, Plus, and Enterprise. Limits are usage-based on monthly page views (events and a share of session extensions count)—plan for growth, not perpetual free volume.

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: Pirsch Analytics vs Swetrix

Vendor also cites CCPA/PECR/Schrems II—treat as claims, confirm with 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 and Hetzner DE analytics hosting, but privacy policy names AWS SES, Google Workspace, Stripe, and Intuition Machines (US-group services) for email/CAPTCHA/payments. 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.

Considerations & known limitations: Pirsch Analytics vs Swetrix
Considerations & known limitations	Pirsch Analytics	Swetrix
US-group account/ops subprocessors	Medium Even with German analytics hosting claims, customer email, CAPTCHA, and payments involve AWS, Google, Stripe, and Intuition Machines. Sovereign or “no US cloud” policies need explicit exception handling or Enterprise architecture review.	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.
No public ISO/SOC or third-party audit	Medium Procurement teams that require ISO 27001 or SOC 2 evidence will need vendor questionnaires or NDA materials; public pages did not show those certs.	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.
Open-source core ≠ free full self-host	Low Teams assuming AGPL means free on-prem of the entire product may be surprised; full on-prem is positioned as Enterprise.	Not listed
Fingerprinting still needs legal fit review	Low Cookie-free hashing is not automatically lawful everywhere without information/consent analysis. Banner removal should be validated for your jurisdiction and tag stack.	Not listed
Page-view usage limits	Low Plans are metered on monthly page views (with events and partial session extensions counting). Hitting the cap can restrict dashboard access until upgrade or cycle reset—model traffic before cutover.	Not listed
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

Pirsch Analytics

Best fit when

EU sites replacing Google Analytics that need pageviews, campaigns, events, and funnels without analytics cookies
Agencies needing multi-site dashboards, client access links, and white-label branding
Teams that can instrument server-side or proxy scripts for better ad-blocker resilience
Buyers who want a German GmbH, downloadable DPA, and Hetzner-Germany residency claims for analytics data
Orgs evaluating Enterprise SAML, raw data access, or on-prem/managed private deployment

Poor fit when

Teams that require a free, full-product self-hosted community edition (core library ≠ full SaaS)
Product or UX research needing session replay, heatmaps, or persistent cross-site user identity
Procurement policies that forbid any US-group subprocessor (email CAPTCHA/billing still touch AWS/Google/Stripe/Intuition Machines)
Heavy product-analytics / multi-product identity graphs (closer to Amplitude/Mixpanel class tools)

Consider instead when

When: You need a free full-stack self-hosted analytics product with AGPL community edition
Consider: Plausible Analytics (CE) or other open full products in your shortlist
Pirsch open-sources the tracking core; on-prem of the full product is Enterprise-scoped.
When: You want the simplest possible privacy-first metrics with a Dutch vendor
Consider: Simple Analytics
Fewer advanced funnel/white-label features; different packaging tradeoffs.
When: You need heatmaps or session replay more than classical web analytics
Consider: Hotjar, Microsoft Clarity, or EU UX-analytics peers
Expect heavier consent and data-minimization review.
When: You must stay inside Google’s advertising and BigQuery measurement ecosystem
Consider: Google Analytics / Google Tag Manager stack
Opposite privacy and transfer posture—only if legal review accepts it.

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.
