Databuddy

Active

Databuddy is an open-source analytics tool under AGPL-3.0, hosted or self-hosted, with plans billed by events: page views, custom events, errors and Web Vitals measurements. It sets no cookies but keeps a persistent visitor ID in local storage by default, and the vendor does not say where hosted data is stored.

Cheapest monthly price for each published traffic level, in events. Hover a point for the plan.

Above the Hobby plan’s 30,000 events the vendor charges for each further 1,000 events, so the price at 100,000 is the plan price plus that usage, not the next plan up.

Strengths

The free plan includes 10,000 events a month, one funnel, two goals, three feature flags, uptime monitoring and public status pages, with no trial period or credit card.
An event is a page view, custom event, error or Web Vitals measurement. Feature flag evaluations and uptime checks do not count toward the quota.
The tracker honors Global Privacy Control, Do Not Track and a stored opt-out, and by default visitor IDs are hashed with a rotating daily salt before storage.
Data can be downloaded as JSON or CSV under Website Settings > Data Export, and a REST API with an OpenAPI schema gives programmatic access to analytics queries.
Settings > Security can limit collection to allowed origins and IP addresses, and requests from unlisted origins then get a 403 response.

Watch-outs

The tracker stores a random visitor ID in local storage and session data in session storage, and the vendor notes that cookieless collection does not automatically remove consent requirements.
The data policy names no storage country. Processing locations depend on the provider and feature, and the subprocessors include Hetzner, Railway, Vercel and Bunny.net.
On the free plan, ingestion pauses after 10,000 events in a month, while paid plans keep collecting and charge tiered rates for extra events.
Error tracking requires Hobby or higher, and scheduled AI investigations come only with the invite-only Business and Scale plans.
The self-hosting steps in the repository need a release image that had not been published as of September 2026, and the README calls self-hosting still evolving.

Who it suits

Databuddy, from Databuddy Analytics, Inc., puts web analytics next to error tracking, Web Vitals, feature flags, short links, uptime monitoring and an AI assistant called Databunny in one dashboard. The documentation has setup guides for React, Next.js, Vue, Nuxt and plain script tags, plus a Node.js SDK for server-side events.

The free plan includes 10,000 events a month with no trial period and no credit card. All plans are billed monthly, and Business and Scale are available by invitation only.

The vendor describes Databuddy as cookieless, but its tracker keeps a random visitor ID in local storage, so read what “cookieless” means here before relying on that label. The code is open source under AGPL-3.0.

Setup

Create a website in the Databuddy dashboard to get its Client ID, then add the script tag with a data-client-id attribute to the head of your pages. React and Next.js projects can install the @databuddy/sdk package and render the Databuddy component once in the root layout. Web Vitals and error tracking stay off until you enable them.

For WordPress, the guide uses a header plugin such as Insert Headers and Footers or a short function in the theme’s functions.php file. Allowed origins and IP restrictions are under Settings > Security. The self-hosted stack runs with Docker Compose on PostgreSQL, ClickHouse and Redis and includes the dashboard, API, event collector and short-link service.

Questions and answers

Does Databuddy use cookies?

No, but it uses browser storage. According to the data policy, the tracker generates a random visitor ID and keeps it in local storage, with session data in session storage. The vendor states that cookieless collection does not automatically remove consent requirements, so check the rules that apply to your site.

Is there a free Databuddy plan?

Yes. The Free plan includes 10,000 events a month, 10 AI credits for Databunny chat, one funnel, two goals and three feature flags. It has no trial period and needs no credit card. Error tracking starts with Hobby, and paid plans are billed monthly.

What happens when I reach the event limit?

On the Free plan, ingestion pauses after 10,000 events for the month. Paid plans keep collecting and add tiered charges for events above the allowance, subject to your billing limits. Feature flag evaluations and uptime checks do not count as events.

Can I host Databuddy myself?

Yes, according to the vendor. The code is open source under AGPL-3.0, and the repository describes a Docker Compose setup with PostgreSQL, ClickHouse and Redis. The same README says the release image it needs has not been published yet and that self-hosting is still evolving.
