AskGSC

France· Web Analytics

Needs review

Shortlist AskGSC when a French-operated, hosted MCP layer is enough to query authorized Google Search Console data inside ChatGPT, Claude, or similar assistants. Skip when you need self-hosted control, write access, a site crawler, or first-party web analytics. Consider Plausible Analytics or Piwik PRO for on-site analytics, or a self-hosted GSC MCP when infrastructure ownership is the requirement.

Matomo by Stackhero

France· Web Analytics

Needs review

Shortlist when you want full Matomo on a dedicated French-operated bare-metal instance with one-click updates and hourly billing—especially if you prefer unlimited site/seat product framing over hit-metered multi-tenant SaaS. Skip when you need EU-only with no US region option, root/SSH access, or a minimal cookieless counter—consider self-hosted Matomo, Friendly Analytics, or Plausible instead.

AskGSC

Hosted remote MCP for Search Console
Provides a remote MCP URL (mcp.askgsc.app) that compatible assistants call on demand. No local MCP server, Google Cloud project, or CSV export is required for the standard flow.
Eleven read-only GSC analysis tools
Tools cover overview trends, query/page/country/device search analytics, period comparisons, opportunity signals, URL inspection (last-known indexing), and sitemap checks. None can modify Search Console or the website.
Read-only Google OAuth scope
Uses https://www.googleapis.com/auth/webmasters.readonly plus identity scopes for sign-in. Users can revoke access from Google account connections; AskGSC states it does not sell Google user data or train its own models on it.
Works across multiple MCP clients
Documented integrations include ChatGPT, Claude, Notion AI, Cursor, Claude Code, and Codex using one hosted MCP server rather than a separate connector per assistant.
Trial then limited free access, optional Pro
A card-free trial starts when Search Console is connected. After the trial the account can remain on a limited free allowance; Pro is an express paid subscription for fuller tool access. Plan figures belong on the vendor pricing page.

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.

Assurance & compliance: AskGSC vs Matomo by Stackhero
Assurance & compliance	AskGSC	Matomo by Stackhero
Independent security / no-logs audit	Not found No public independent audit PDF or report linked from the site.	Not found ISO 27001 and bug-bounty openness claimed; no public independent no-logs audit report specific to analytics found.
ISO 27001	Not found	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.
SOC 2 / SOC 3	Not found	Not found No SOC 2/3 claim found on certifications/privacy/GDPR pages reviewed.
GDPR / EU data protection	Vendor claimed French controller; GDPR rights section and CNIL reference on privacy policy. Confirm DPA for B2B.	Vendor claimed French entity; public GDPR & DPA page; customer controller / Stackhero processor model; EU region option for service data.
US CLOUD Act exposure (indicative)	Partial EU entity / no known US parent, but Google, Supabase, Stripe, Cloudflare/Lovable, and user-selected US AI assistants appear in the public data path. Not legal advice.	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.
Data processing agreement (B2B)	Not found No public DPA download found; ask vendor.	Vendor claimed DPA applies automatically with Terms of service; PDF downloadable from the GDPR & DPA page.
EU AI Act	Partial AskGSC is an MCP data gateway to user-selected AI assistants rather than a published generative model. AI Act obligations may still matter for how connected assistants are used; confirm with counsel.	Not applicable Web analytics hosting; not positioned as an AI system product.

Considerations & known limitations: AskGSC vs Matomo by Stackhero
Considerations & known limitations	AskGSC	Matomo by Stackhero
US-group cloud and SaaS in the data path	Medium Privacy policy names Google, Supabase, Lovable, and Stripe; MCP DNS uses Cloudflare Pages. Search Console results also flow to the AI client you connect. Teams with strict EU-only subprocessor rules need a written region and subprocessor schedule.	Not listed
No public independent audit or cert package	Medium ISO 27001, SOC 2, and independent security audits were not found on public pages. Security claims rest on vendor documentation (encrypted refresh tokens, read-only scope).	Not listed
Depends on Google Search Console data quality	Low Vendor docs note GSC data may be delayed, aggregated, or incomplete, and average position is not a real-time ranking. AI interpretations remain the user's responsibility.	Not listed
Very new legal entity	Low KALYVOX appears in the French registry as created in January 2026. Expect limited public operating history and incomplete legal placeholders (retention periods, mediator contact) on some policy pages.	Not listed
Optional US hosting region	Not listed	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.
EU backups when primary is US	Not listed	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.
No SSH / managed-only host	Not listed	Low Cannot install arbitrary system software or agents; support hours stated as CET office hours for basic platform support—not full Matomo application consulting.
Limited named subprocessor list	Not listed	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.
ISO certificate vendor-published	Not listed	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.
Matomo privacy configuration is yours	Not listed	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.

Fit

AskGSC

Best fit when

Founders and SEO operators who already decide inside ChatGPT, Claude, Notion AI, or coding agents
Teams that need recurring GSC questions (period compare, losing pages, low CTR) without CSV exports
Buyers who want read-only Google access and a hosted MCP URL rather than running their own server
Organizations that prefer a French contracting entity for a lightweight SEO analysis connector

Poor fit when

Needs to write to Search Console, request indexing, or edit the website through the connector
Requires self-hosted MCP, custom tool code, or fully controlled token storage and regions
Looking for cookieless first-party web analytics instead of Google search performance data
Procurement blocked without a public DPA, ISO 27001, or independent audit package

Consider instead when

When: You need first-party site analytics rather than Google Search Console metrics
Consider: Plausible Analytics or Piwik PRO
Different data source: on-site collection vs Google search reports
When: You must operate the MCP stack and credentials yourself
Consider: Self-hosted Google Search Console MCP
AskGSC's own compare pages frame this as higher setup for more control
When: Manual one-off analysis is enough
Consider: Google Search Console UI and CSV exports
No third-party MCP or assistant data path

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.

Open questions for due diligence

AskGSC

Will KALYVOX sign a B2B DPA and publish an authoritative subprocessor list with regions?
Which Supabase and Lovable regions host AskGSC production data today?
Are ISO 27001, SOC 2, or independent penetration-test reports available under NDA?
What exact retention applies to technical logs and backups (privacy page still has placeholders)?

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)?
