What is SolidInvoice?

SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.

After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.

What is CloudZero?

CloudZero ships Kubernetes rightsizing directly inside MCP clients, bringing cloud cost ops into AI assistants

CloudZero is shipping product features at a fast clip alongside a high-volume content program. On the product side: MCP server credential self-service is live, and Kubernetes workload rightsizing can now be triggered from within an MCP client like Claude or Cursor — a direct integration of cloud cost operations into AI coding workflows. The content calendar is dominated by AI spend analysis and LLM cost framing, positioning CloudZero as the cost intelligence platform for AI-era infrastructure.

SolidInvoice vs CloudZero: editorial side-by-side

S0.0

SolidInvoice finally shipped the 3.0 it spent a year staging in alphas and betas.

◆ Current state

After more than twelve months of alpha and beta releases, SolidInvoice 3.0 landed in June with the accumulated work of that cycle: email verification, Google OAuth, two-factor authentication, real user profiles, flat-rate tax support and a Meilisearch-backed search layer. Underneath it, the project moved onto a shared platform config and pulled trial and SaaS logic into an external bundle. The 2.3 line ran in parallel the whole time, absorbing security backports.

◆ Where it's heading

Two threads run through this changelog. The visible one is identity and account management catching up to what users expect from a billing app — signup verification, OAuth, 2FA, self-serve company deletion. The less visible one is the codebase being restructured around reusable solidworx platform components with Sentry and Prometheus instrumentation, which is the shape of a project preparing to run itself as a hosted service rather than only as a download.

◆ Prediction

With 3.0 out and 3.0.1 already repairing the upgrade migration path, the near-term work is likely more 3.0.x stabilization for people coming off 2.3 rather than new features.

CloudZero ships Kubernetes rightsizing directly inside MCP clients, bringing cloud cost ops into AI assistants

◆ Current state

CloudZero is shipping product features at a fast clip alongside a high-volume content program. On the product side: MCP server credential self-service is live, and Kubernetes workload rightsizing can now be triggered from within an MCP client like Claude or Cursor — a direct integration of cloud cost operations into AI coding workflows. The content calendar is dominated by AI spend analysis and LLM cost framing, positioning CloudZero as the cost intelligence platform for AI-era infrastructure.

◆ Where it's heading

CloudZero is moving from cost observability platform to an active optimization tool embedded in AI developer workflows via MCP. The Kubernetes rightsizing MCP feature is a meaningful step toward cost governance being inline with how engineers work, rather than a separate dashboard. Expect more workload-level optimization actions surfaced through MCP as the integration matures.

◆ Prediction

Rightsizing for other resource types (ECS tasks, Lambda provisioned concurrency, RDS instances) through MCP actions will follow as CloudZero extends the action surface beyond Kubernetes.
