Your data, your account

Vizoalica runs on Cloudflare Workers, D1, and R2 in your own account. There is no hosted service between you and your visitors’ data.

Privacy-minimal by default

It collects page views and custom events, with URLs, referrers, and properties minimised before delivery. It never collects form values, page text, or session replay, and it records the consent state on every event.

One command to install

pnpm vizoalica install deploys the backend, connects this computer as the console, and sends sample page views, in about two minutes.

A console that stays local

The operator console runs on demand on an admin’s computer. Its browser never holds a remote credential, and there is a clear line between viewing analytics and managing setup.

Open standards

CloudEvents batches, JSON Schema validation, and short-lived signed (JWT/JOSE) ingest tokens, under the MIT license.

Made to be read by people and agents

Plain Markdown guides, a step-by-step activation flow, and an llms.txt so coding agents can find their way around.

  4. vizoalica.dev: open-source, self-hosted web analytics on your own Cloudflare account.

Set it up in three parts ​

A Vizoalica installation has three parts. Set them up in this order, because each one needs something the previous one produces.

1. BackendA Cloudflare Worker, database, and storage in your account that receive, filter, and store events. Deploy the backend
2. ConsoleA local web app on an admin’s computer for projects, websites, and analytics. Set up the console
3. WebsiteYour site loads the browser SDK and a small token endpoint. Activate a website

Try it with one command ​

You need Node.js 22 or newer, Git, and a Cloudflare account. macOS and Linux are supported.

sh
git clone https://github.com/ehud-am/vizoalica.git && cd vizoalica
corepack enable && pnpm install
pnpm vizoalica install

It creates a real backend in your Cloudflare account, sets up this computer as the console, and sends sample page views for a make-believe website, so you are looking at real analytics about two minutes later. Only the sample data is throwaway. Read the quick start or see the console first.

Built in the open ​

Vizoalica is open source under the MIT license. Read how it handles data in the privacy defaults, what it costs to run in the cost model, and what changed in the release notes.

Released under the MIT License. Visitor data stays in your own Cloudflare account.
