Chitragupta – Kafka Cost Attribution Tool

An open-source cost attribution platform for Kafka that breaks down infrastructure costs by identity and topic level. Targets engineering teams using Confluent Cloud who need detailed cost visibility. Could monetize as a managed SaaS alternative to the open-source version.

Kafka costs on Confluent Cloud have become a genuine pain point as teams scale event-driven architectures — Confluent's consumption-based pricing makes it easy to rack up unexpected bills, and there's currently no native tooling that attributes those costs to specific teams, topics, or services with any granularity. No clear incumbent owns this space; the closest substitutes are generic cloud cost platforms like Apptio or homegrown dashboards built on Confluent's metrics API. The $1k–8k/mo revenue band is plausible but tight — the buyer is typically a platform engineering team that already has a free open-source version to fall back on, which compresses willingness to pay and makes the upsell to managed SaaS a genuinely hard conversation. The biggest risk is that Confluent itself closes the gap by shipping better native cost attribution, which would commoditize the entire value proposition overnight.
