GreenKube – Kubernetes Cost & CO2 Optimization Engine

An open-source SaaS tool that analyzes K8s clusters to show energy consumption and CO2 emissions per pod, with actionable recommendations to reduce both. Designed for small/medium teams who can't afford enterprise FinOps tools. Target users are DevOps teams and companies caring about cloud costs and sustainability.

Cloud sustainability reporting is gaining real traction as the EU's CSRD regulation pushes more companies to measure and disclose Scope 3 emissions, which includes cloud infrastructure, making the timing genuinely relevant rather than speculative. Kubecost is the closest incumbent and already owns significant mindshare in the K8s cost optimization space, so the CO2 angle is the meaningful differentiator — without it, there's no wedge. The $2k–10k/mo revenue band is plausible for a prosumer devtool with a freemium open-source core converting to paid reporting or team tiers, but it requires either volume (many small accounts) or a faster-than-expected move upmarket. The biggest risk is that most small/medium DevOps teams treat carbon metrics as a nice-to-have dashboard rather than a decision-making input, meaning adoption stalls at the free tier and the paid conversion rate never justifies the infrastructure and compliance work required to make the emissions data credible.
