Self-hosted analytics, without the sprawl
Run product analytics on your own servers and keep every event inside your infrastructure. Pug self-hosts as a single Go binary — not a fleet of services — under AGPL-3.0, free forever.
Why teams run analytics themselves
Your data never leaves
Events are written to your own ClickHouse, on your own servers. Nothing is sent to a third party — the whole point of self-hosting analytics.
Compliance on your terms
Pick the region, set the retention, control access. Keeping data inside your own infrastructure simplifies GDPR and data-residency requirements.
No black box
AGPL-3.0 — read every line, audit how events are processed, and change what you need. Self-hosting and the source go together.
No per-event bill
Self-hosting is free forever. You pay for the hardware you already run, not for each event a SaaS meters.
One binary, three dependencies
Most self-hosted analytics tools mean operating several services. Pug keeps it small: one Go process runs the API and every worker.
- Go binary Server + every worker, in one process
- PostgreSQL Accounts, projects, and config
- ClickHouse The event and analytics store
- NATS The async event pipeline
The full product, on your servers
Self-hosting Pug is not a stripped-down build — it is the same product the cloud runs.
- Autocapture: page views, clicks, scrolls, form submits, rage and dead clicks
- Six insight types: Trends, Funnels, Retention, Segmentation, User flow, Top K
- Unified profiles — anonymous activity merges into one person on identify()
- Dashboards with shared time windows and period-over-period comparison
Self-hosted analytics, answered.
What is self-hosted analytics?
Analytics software you run on your own servers, so all visitor and event data stays inside your infrastructure instead of being sent to a third-party cloud. Pug is built to be self-hosted this way under AGPL-3.0.
What do I need to run Pug?
Pug is a single Go binary backed by PostgreSQL (config), ClickHouse (events), and NATS (the queue). One process runs the API and every worker, so the operational footprint is small. See the setup guide for specifics.
Is self-hosting really free?
Yes — free forever under AGPL-3.0, with no event limits or licensing fee. You provide the infrastructure; Pug provides the software.
Can I move to the cloud later, or vice versa?
Yes. The same code runs our managed cloud and your own deployment, and your data is exportable either way, so you are never locked in.
How is this different from Google Analytics?
Google Analytics is free but Google-hosted — your data lives on their infrastructure. Self-hosted Pug keeps every event on your servers, unsampled, and open source.
Own your analytics, end to end.
Open source, self-hostable as one Go binary, and free during open beta. Read the self-hosting guide or spin up the free cloud in minutes.
