⚙ Full Stack
Elixir/Phoenix application handling ingestion and the dashboard UI, Postgres for account/site configuration, and ClickHouse as the analytics event store optimized for high-cardinality aggregation queries.
📈 Scaling Analysis
ClickHouse is purpose-built for exactly this workload (append-heavy, aggregation-heavy event analytics) and scales to very high event volumes with columnar storage, while Phoenix's BEAM concurrency model handles high connection counts efficiently — genuinely strong scaling characteristics for the analytics use case.
🚀 Running on Nexlayer
Three-pod deploy: `plausible` app pod, `postgres.pod:5432` for accounts, and `clickhouse.pod:8123` for event data; the public tracking script URL is server-controlled and safe to embed in customer sites by design, a standard and intentional pattern for analytics tools, not a security gap.
