Germany· Web Analytics
Needs review
Shortlist Sitesights when you need German-operated cookieless web analytics with real-time dashboards, funnels, page flow, and a server-side API—especially agencies and SaaS teams that want Hetzner Germany hosting claims without running Matomo. Skip when you need public ISO/SOC audits, long-term visitor identity, session replay, or a fully published subprocessor pack; consider Plausible Analytics or self-hosted Matomo instead.

Cookieless aggregation without IP storage
Per the privacy policy, Alceris does not set cookies, session IDs, or similar client storage; IPs are not logged; the full User-Agent is not stored. Only aggregated fields such as page URL, referrer, parsed browser/OS, language, and timezone-based country are retained—aimed at sites that want stats without an analytics cookie banner.
One-line async script, deferred events, WordPress plugin
Install via a single async script from alceris.com with your site data-id (docs include a deferred alceris() queue so early events are not lost). WordPress operators can use the official plugin and paste the dashboard site ID. SaaS-only—there is no self-hosted server package.
Realtime pageviews and custom events with metadata
Pageviews and events are processed immediately into the dashboard. Custom events are sent with alceris('event', name, { ...metadata }), useful for button clicks, form steps, or content attributes without building a full product-analytics stack.
UTM campaigns, outbound links, and cross-domain flows
UTM parameters are extracted for campaign reporting; outbound link clicks are tracked automatically; cross-domain tracking follows visitors across owned domains. Scope is web traffic measurement—not session replay or heatmaps.
Optional Google Search Console and first-party proxy
Connect Search Console to import query impressions, clicks, and terms (data removed on unlink). Docs also describe reverse-proxying script.js and the img.alceris.com data endpoint through your own domain so ad-blockers are less likely to drop hits—at the cost of operating that proxy yourself.
Cookieless 48-hour rotating session hash
Standard tracking does not set cookies. Sitesights generates a server-side salted hash from IP, User-Agent, and site id with a salt that rotates every 48 hours, so long-term cross-day visitor re-identification is intentionally broken. Useful when teams want essential traffic metrics without a cookie-consent banner solely for analytics—confirm legal basis with counsel for your jurisdiction and data fields (including geo).
Sub-1 KB client script plus WordPress and Shopify plugins
Drop-in client snippet marketed as under 1 KB, with official WordPress and Shopify integration paths for non-engineers. Fits marketing sites and stores that need quick instrumentation without a heavy tag manager stack.
Server-side REST API with C# and Node libraries
Send page views and events from your backend with API-key auth so ad blockers cannot strip the beacon. MIT-licensed C# and Node.js libraries on GitHub speed integration; keep API keys off the client. Preferred path for accuracy-critical SaaS and app backends.
Real-time overview with campaign and device filters
Live dashboard for visitors, pageviews, and sessions with advanced filters, UTM/campaign views, geo, browser, OS, screen size, and daytime patterns. Aimed at operators who want essential marketing analytics in one place rather than a full product-analytics suite.
Custom funnels and page-flow journey maps
Build multi-step funnels and visual page-flow maps to see entry paths, routes, and exits. Helps conversion and UX work without session replay. Depth is journey-oriented, not identity-graph product analytics.
Multi-project workspaces with roles for agencies
Group sites and apps into projects, assign roles/permissions, and invite clients or teammates. Marketing materials reference high ceilings for team seats and properties on paid plans—verify current limits on the official pricing page.

| Considerations & known limitations | Alceris Analytics | Sitesights |
|---|---|---|
| Solo / small-operator continuity | Medium Imprint shows an individual operator in Straubing. Terms provide service as-is with email support on reasonable effort and reserve the right to modify or discontinue the service. Practical impact: backup exports and an exit plan matter more than with a large SaaS vendor. | Not listed |
| Thin public compliance packaging | Medium No ISO/SOC claims, no independent audit, no public DPA template, and no named infrastructure subprocessor list despite terms referring to third-party hardware/storage vendors. Practical impact: slower security review for regulated buyers. | Not listed |
| Optional Google Search Console path | Low Connecting Search Console pulls query metrics from Google into Alceris. Leave it disconnected if US providers are out of policy for any analytics-adjacent data. | Not listed |
| Billing via Paddle MoR | Low Paid plans are contracted with Paddle, not Alceris directly. Review Paddle's terms and data role for finance/procurement. | Not listed |
| WordPress plugin maintenance signal | Low WordPress.org lists the plugin as not tested with the latest major WP releases and few active installs. Prefer manual script install or re-test thoroughly on your WP version. | Not listed |
| No public independent security audit | Not listed | Medium ISO 27001, SOC 2, and third-party security audits were not found on public pages. Enterprises may need to commission questionnaires or wait for vendor artifacts under NDA. |
| Incomplete public subprocessor list | Not listed | Medium Hetzner (product) and Cloudflare (marketing site) are documented; backups, email, support, and monitoring vendors for the SaaS are not fully listed. Ask for a current subprocessor annex. |
| US-group CDN on marketing site | Not listed | Low Privacy policy lists Cloudflare Inc. (US) for the public website CDN. Separate from claimed Hetzner product data path, but relevant to overall vendor surface area. |
| 48-hour hash limits long-term visitor analytics | Not listed | Low By design, the rotating salt prevents durable cross-day visitor recognition. Teams needing retention cohorts or multi-week funnels by person must model events differently or choose product-analytics tools. |
| On-premise availability is marketing-only detail | Not listed | Low About page claims on-prem hosting; docs do not provide a self-serve install guide. Treat as sales-assisted until scope is confirmed in writing. |
When: You want a more established cookieless SaaS brand with stronger public compliance packaging
Consider: Plausible Analytics or Simple Analytics
Similar lightweight privacy analytics category; different ownership and documentation maturity
When: You need self-hosted or on-prem control of the analytics stack
Consider: Matomo (self-hosted) or catalog Matomo hosting variants
Alceris is cloud-only; proxying the script still sends data to Alceris
When: You need German-hosted open-source cookieless analytics with a different product surface
Consider: Pirsch Analytics
Peer German privacy-analytics option for side-by-side evaluation
When: You need full GA4-class product and marketing analytics depth
Consider: Google Analytics (accept its data model) or a heavier EU suite
Alceris intentionally stays narrow
When: You want a minimal EU cookieless SaaS or a well-known self-host option
Consider: Plausible Analytics
Simpler metric set; strong self-host story. Sitesights markets deeper funnels/page-flow and multi-project agency features.
When: You need full self-host control, on-prem by default, or mature open-source governance
Consider: Matomo (self-hosted)
Heavier stack, deeper feature surface, and you operate the data plane yourself.
When: You need identity-rich product analytics, retention cohorts, or event warehouses
Consider: Mixpanel or similar product-analytics platforms
Different category—Sitesights is website/app growth analytics, not a full product analytics suite.
When: You need heatmaps, recordings, or UX feedback loops
Consider: Hotjar, Microsoft Clarity, or EU UX-analytics tools
Sitesights focuses on traffic, events, funnels, and flows—not session replay.
