Real-Time PostgreSQL Change Data Capture via WebAssembly
Teams building real-time features need change data capture from PostgreSQL but existing solutions (Debezium) require Kafka, JVM, and heavy infrastructure. A lightweight CDC library running as a Wasm plugin inside the database reduces operational complexity to near-zero.
Problem Statement
Setting up change data capture from PostgreSQL requires deploying Kafka, Kafka Connect, Debezium, and a JVM runtime. For a team that just wants to know when a row changes, this is 4+ services of operational overhead for conceptually simple functionality.
The Idea
A WebAssembly-based PostgreSQL extension for lightweight change data capture that eliminates Kafka and JVM dependencies, streaming row-level changes directly to application webhooks or message queues.
Why Now
Real-time features are expected in every application but CDC infrastructure is overengineered for most teams. Wasm in databases is becoming viable. Debezium's complexity frustrates small teams. Event-driven architecture demand exceeds available simple tooling.
Target User
Backend developers needing real-time database event streaming without Kafka
Target Market
Database tooling, event-driven architecture, real-time application infrastructure

Coding agents now produce more PRs than human engineers on many teams, overwhelming reviewers with diffs they cannot read line-by-line. A triage system that evaluates PR risk based on code sensitivity, author verification steps, and agent conversation context lets reviewers focus on the PRs where human judgment changes outcomes. Haystack demonstrated this model, reaching strong HN traction.
