Cometly vs Pirsch Analytics in 2026: B2B ad attribution vs cookieless, GDPR-first web analytics
One requires a sales call to attribute ad spend to closed-won ARR in a CRM. The other starts at $6 a month, drops the cookie banner entirely, and is hosted in Germany.
Cometly
Pirsch Analytics- Cometly attributes ad spend to closed-won ARR pulled from a CRM, requiring a sales call and usage-based pricing. Pirsch publishes full pricing from $6/month for 10,000 page views with a 30-day free trial and no credit card required.
- Pirsch is fully cookieless and stores no personally identifiable information, letting sites remove their cookie consent banner entirely. Cometly relies on a pixel and server-side Conversion API and makes no cookieless or consent-related claims.
- Cometly auto-detects AI-sourced traffic from ChatGPT, Gemini, Grok, and Google AI Overviews. Pirsch has no equivalent AI-referral traffic detection feature in its published feature set.
- Pirsch offers extensive white labeling and custom domains on its Plus plan, aimed squarely at agencies managing multiple client sites. Cometly has no white-label delivery feature at any tier.
- Cometly ships an MCP integration that lets Claude query attribution data through natural language, on its Enterprise plan. Pirsch has no AI agent integration of any kind.
- Pirsch is hosted on servers in Germany and is Schrems II compliant by design, with an open-source core available for audit. Cometly discloses no hosting location or open-source component.
- Cometly Enterprise adds Snowflake and BigQuery sync for warehouse-native attribution. Pirsch's Enterprise tier adds on-premise installation and SAML SSO instead, reflecting a compliance-first rather than warehouse-first roadmap.
Cometly and Pirsch Analytics rarely compete for the same budget, but they get compared because both promise something most analytics tools do not: Cometly promises to connect ad spend to actual closed-won revenue in a B2B CRM, and Pirsch promises accurate traffic data without a cookie consent banner at all. Cometly is a sales-led, usage-priced attribution platform built for B2B SaaS companies running paid campaigns. Pirsch is a self-serve, transparently priced, privacy-first web analytics tool built and hosted in Germany for any site owner who wants to drop their cookie banner. If you are weighing these against each other, you are probably solving one of two very different problems: proving marketing ROI to a CFO, or replacing Google Analytics without the compliance overhead.
The tools at a glance
Cometly
B2B SaaS ad attribution that connects every campaign dollar to pipeline created and closed-won ARR
Cometly tracks the complete customer journey from first ad impression to closed-won ARR, connecting Google Ads, LinkedIn Ads, and Meta Ads sessions to the pipeline and revenue they eventually produced. The core metric is LTV ROAS calculated against actual CRM deal values, which matters for B2B SaaS companies where a lead can take 60 to 90 days to close and might not close through the same channel that first touched them.
A server-side Conversion API supplements pixel tracking to recover conversion events that ad blockers and iOS restrictions would otherwise erase, and Cometly auto-detects AI-sourced traffic from ChatGPT, Gemini, Grok, and Google AI Overviews. An MCP integration lets Claude pull campaign ROAS and pipeline data directly into a conversation, though that feature is gated to the Enterprise plan.
None of this is quick to access. Pricing is usage-based on website sessions and disclosed only after a sales call, with no clearly advertised free trial. Cometly is also explicit that it is built for B2B SaaS specifically; businesses without a CRM deal pipeline get little value from what the platform is optimized to do.

Pirsch Analytics
Cookieless, GDPR-compliant web analytics made and hosted in Germany, with no consent banners required
Pirsch Analytics replaces Google Analytics without cookies, without a consent banner, and without storing any personally identifiable information. It identifies visitors using an anonymized hash derived from IP address and User-Agent string, discarding the source data after calculation, which satisfies GDPR, CCPA, PECR, and Schrems II without requiring a cookie banner at all.
Standard features cover page views, referrers, UTM tracking, session durations, and a real-time dashboard, while the Plus plan adds session analysis, funnels, A/B testing, tag-based segmentation, and full white labeling with custom domains for agencies managing client sites. A RESTful API and script proxies support server-side tracking that ad blockers cannot touch.
Pricing is based on monthly page view volume rather than seats, starting at $6 a month for 10,000 page views on Standard, or $12 on Plus with no website cap. A 30-day free trial with no credit card requirement covers the full feature set, and Pirsch supports importing historical data from Google Analytics, Plausible, or Fathom so switching does not mean starting from zero.
| Feature | Standard From $6/mo | Plus From $12/mo | Enterprise Custom |
|---|---|---|---|
| Websites | 50 | Unlimited | Unlimited |
| Cookieless tracking | Yes | Yes | Yes |
| Funnels and A/B testing | No | Yes | Yes |
| White labeling and custom domains | No | Extensive | Extensive |
| On-premise installation | No | No | Yes |
| SAML SSO | No | No | Yes |

Considering AI Peekaboo alongside Cometly and Pirsch Analytics?
Cometly can tell you that a visitor arrived from ChatGPT, Gemini, Grok, or Google AI Overviews, but that measures referral traffic only, not what the AI model actually said about your brand in the answer that sent them your way. Pirsch has no AI traffic detection feature at all. Neither tool monitors brand mentions inside AI-generated answers. AI Peekaboo tracks exactly that, across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode, with a read and write API on every plan starting at $50 per month.

CometlyPirsch AnalyticsPirsch AnalyticsCometlyPirsch AnalyticsCometlyPirsch AnalyticsThese two tools are solving different problems for different audiences. Cometly is a premium, sales-led attribution platform for B2B SaaS companies that need to prove ad spend produced closed-won revenue, and the friction of a demo call is part of how that category of tool is typically sold. Pirsch is a self-serve, transparently priced web analytics tool for any site owner who wants accurate traffic data without a cookie banner, and its entire value proposition depends on being easy to try and easy to trust. Comparing them head to head only makes sense if you are unclear on which category your actual need falls into.
Bottom line
Book the Cometly demo if you run a B2B SaaS pipeline and need to connect specific ad campaigns to closed-won ARR 60 to 90 days later. Start the Pirsch free trial today, no card required, if you want to replace Google Analytics, drop your cookie banner, and get GDPR compliance without a sales process. If you need both revenue attribution and privacy-first traffic reporting, expect to run separate tools, since Pirsch does not attribute ad spend and Cometly does not offer cookieless, consent-free tracking.
Frequently asked questions
Can Pirsch Analytics replace Cometly for tracking ad campaign ROAS?
No. Pirsch has no ad spend attribution or CRM integration features. It reports page views, referrers, sessions, and conversion goals, but it does not connect ad campaigns to closed-won revenue the way Cometly's full-funnel attribution does. Pirsch is a web analytics tool, not a revenue attribution platform.
Does Cometly let me drop my cookie consent banner the way Pirsch does?
No. Cometly uses pixel-based and server-side tracking without making any cookieless or consent-related compliance claims. Pirsch is built specifically to be cookieless and to collect no personally identifiable information, which is what allows sites using it to remove their cookie banner entirely under GDPR, CCPA, and PECR.
Which tool is cheaper, Cometly or Pirsch Analytics?
Pirsch is dramatically cheaper and fully transparent, starting at $6 a month for 10,000 page views with published pricing on every tier. Cometly discloses no pricing without a sales call and bills usage-based on website sessions. The comparison is not apples to apples, since Cometly's cost reflects CRM-integrated revenue attribution rather than traffic reporting.
Is Pirsch Analytics a good fit for a B2B SaaS company like Cometly targets?
Pirsch can serve as the general web analytics layer for a B2B SaaS site, showing traffic, referrers, and conversion goals without a cookie banner. It does not, however, replace what Cometly does: connecting a specific ad campaign to a closed-won CRM deal weeks or months later. Companies with both needs typically run a web analytics tool like Pirsch alongside a dedicated attribution tool like Cometly.
Do either Cometly or Pirsch Analytics track AI referral traffic the same way?
No. Cometly automatically detects and attributes traffic from ChatGPT, Gemini, Grok, and Google AI Overviews as named channels alongside paid and organic sources. Pirsch's published feature set has no equivalent AI traffic source detection.
Can agencies white-label either Cometly or Pirsch Analytics for client reporting?
Pirsch, yes, on its Plus plan, which includes custom domains, custom logos, color themes, and unique client access links. Cometly has no white-label delivery feature at any tier, since it is built for in-house B2B revenue teams rather than agency client reporting.
