WaveHouse: an open-source "Supabase for ClickHouse" that drops the Kafka middleman
WaveHouse is a single Apache-2.0 binary that sits in front of ClickHouse and abstracts away its sharpest edges: it batches async writes through a durable NATS WAL, pushes real-time updates to browsers over SSE, and validates every ingest against the live schema. The pitch is a Supabase-for-ClickHouse or open-source Tinybird with row-level policies and a ~1.4KB TS SDK. Still alpha and built in the open, it's one of the cleaner answers to "I need user-facing analytics without Kafka."
