Privacy‑first web analytics without the cookie banner.
Mnemar is open-source, cookieless analytics you self-host. Get the numbers that matter — pageviews, sources, funnels, goals, and a live view — without consent banners, third parties, or handing over your visitors' data.

<script defer src="https://analytics.example.com/mnemar.js" data-site="yoursite.com"></script> docker compose -f deploy/docker-compose.yml up -d helm install mnemar deploy/helm/mnemar First-party by design. The script and the data live on a domain you own.
Serve the tracker from your own subdomain. No third-party requests, no shared ad-network identifiers — and ad blockers leave it alone.
Counts people, not identities. No cookies. No fingerprints.
A salted hash rotates every day, so a visitor can't be followed across days or across sites. You measure traffic without surveilling anyone.
Big-tech analytics makes your visitors the product.
-
01.
Consent fatigue
Cookie-based analytics force a consent banner onto every visitor. It hurts the experience, tanks opt-in rates, and leaves your data full of holes.
The banner is a tax you pay on every single visit — and you still lose the data.
-
02.
Your data isn't yours
Google Analytics ships your visitors’ behavior to a third party, then rents your own numbers back to you — sampled, delayed, and on their terms.
-
03.
Privacy & legal risk
Regulators across the EU have ruled mainstream analytics non-compliant. Sending visitor data offshore is a liability you carry, not them.
Everything you measure. Nothing you shouldn't.
Mnemar tracks what helps you make decisions and deliberately collects nothing that identifies a person. Privacy and product analytics are not a trade-off.
- 01
Cookieless identity
Visitors are counted with a daily-rotating salted hash — no cookies, no persistent IDs, no cross-site profile. Nothing to consent to.
- 02
Real-time view
See who is on your site right now — top pages, sources, and countries — updating live, the moment traffic lands.
- 03
Funnels & goals
Define conversion goals and multi-step funnels. Find exactly where visitors drop off, powered by ClickHouse windowFunnel.
- 04
Self-hostable
One docker-compose file or a community Helm chart. Runs on a single box or scales out with Kafka — your infra, your rules.
- 05
Public stats API
Every metric on the dashboard is available over a documented JSON API. Build reports, embed widgets, export raw — your data, programmatically.
- 06
Privacy by design
IP addresses are never stored. Configurable per-tenant retention (24 months by default). GDPR, CCPA, and PECR friendly out of the box.
From page view to dashboard.
-
01
Drop in the tag
Add one small script to your site, served first-party from your own domain. It sends a cookieless, anonymous event on each page view.
script src="…/mnemar.js" data-site="yoursite.com"
-
02
Ingest at the edge
The Go collector accepts events, buffers them to a write-ahead log so nothing is lost, and streams them into ClickHouse for analytical queries.

03
See it live
Open the dashboard for real-time visitors plus historical traffic, sources, top pages, funnels, and goals — or pull it all over the JSON API.

Analytics shouldn't cost your visitors their privacy — or cost you control of your own data.
Frequently asked
-
01 Is Mnemar a Google Analytics alternative?
A Yes. Mnemar gives you the metrics you actually use — pageviews, visitors, sources, top pages, funnels, goals, and a real-time view — without cookies, without a third party, and without sending your visitors’ data anywhere you don’t control.
-
02 Do I need a cookie consent banner?
A No. Mnemar is cookieless and stores no personal data or persistent identifiers, so in most jurisdictions it does not require the consent banners that cookie-based analytics do. (This is not legal advice — check your local requirements.)
-
03 Is it GDPR and CCPA friendly?
A It is built for it. No cookies, IP addresses are never stored, and visitors are counted via a salted hash that rotates daily so they cannot be tracked across days or sites. You also control data retention per tenant.
-
04 How do I install it?
A Add one script tag to your site, and self-host the backend with the provided docker-compose file or the community Helm chart. The tracker is a single small script with no dependencies.
-
05 Can it handle high-traffic sites?
A Yes. Events are buffered to a write-ahead log at the edge and stored in ClickHouse, an analytical database built for billions of rows. Start on one box; scale the collector out behind a queue when you need to.
-
06 Is it really free?
A Mnemar is open source under the MIT license. Self-host it for free, forever. Read the source, audit it, and change anything you like.
Own your analytics. Self-host in minutes.
Mnemar is open source and free to run. Clone the repo, bring up the stack with docker-compose or Helm, drop in the tag, and watch the traffic roll in — live.
