Quantalog vs PostHog
A lighter, privacy-first PostHog alternative for teams who want traffic analytics, funnels and SEO audits without cookies, a consent banner or a heavy SDK.
PostHog is a full product-analytics platform — session replay, feature flags, experiments, a data warehouse. Quantalog is web analytics with SEO audits and reporting. This page is for teams who adopted PostHog for pageviews and funnels and found the rest was more than they needed.

Quantalog vs PostHog, point by point
| What you are comparing | Quantalog | PostHog |
|---|---|---|
| Consent banner requiredQuantalog | No. Nothing is stored in the browser. | PostHog sets cookies by default and identifies users, so a consent banner is generally required. |
| Script weightQuantalog | Under 1 KB, loaded async. | The posthog-js SDK is substantially larger, more so with session replay and autocapture enabled. |
| Cookieless optionQuantalog | The only mode. No configuration needed. | A cookieless / memory-persistence mode exists but is not the default and limits some features. |
| Funnels, cohorts and custom eventsBoth | Included on every plan. | Included, and deeper — path analysis, correlation, retention breakdowns. |
| Session replay, feature flags, experimentsPostHog | Not offered. | Core parts of the platform. |
| SEO audits and Lighthouse scoresQuantalog | Built in. | Not offered. |
| Scheduled email and WhatsApp client reportsQuantalog | Yes, with an AI summary and XLSX attachment. | Dashboards can be subscribed to by email; no WhatsApp, no client-report packaging. |
| Give analytics to your own customersQuantalog | Multi-tenant Platform API — a project per customer. | Multiple projects exist, but reselling analytics is not a packaged use case. |
| PriceBoth | Free to 10k pageviews a month, then usage-based. | Generous free tier by event volume, then usage-based across each product. |
When PostHog is the better choice
Stay with PostHog if you use session replay, feature flags, A/B experiments or its SQL data warehouse. Quantalog does none of those and is not trying to; it is the smaller tool on purpose.
Common questions
- Is Quantalog a replacement for PostHog?
- Only for the web-analytics part — traffic, referrers, funnels, goals and events. It does not replace session replay, feature flags or experiments, and it has no data warehouse.
- Why would I move from PostHog to Quantalog?
- Usually to drop the consent banner and the SDK weight when the team only ever used PostHog for pageviews and funnels, and the rest of the platform sat idle.
- Does Quantalog need a cookie banner where PostHog does?
- Quantalog never needs one; it is cookieless in its only mode. PostHog needs one in its default configuration because it sets cookies and identifies users.
