CDviz vs Middleware ​

Both CDviz and Middleware are open-source, Apache 2.0 platforms targeting SDLC observability and DORA metrics. The core difference is the data model: Middleware polls your tools (GitHub, GitLab, Jira) on a schedule; CDviz ingests a real-time event stream from your pipeline using the CDEvents standard.

Key differences ​

  • Data model: Middleware polls GitHub, GitLab, and Jira APIs on a schedule to compute metrics. CDviz receives events pushed from your pipeline tools in real time using the CDEvents open standard — no polling delays, no API rate-limit gaps.
  • DORA calculation: Middleware derives DORA metrics from PR merge history and deployment annotations pulled from your VCS. CDviz derives DORA metrics from CDEvents emitted directly by your CI/CD toolchain at the moment they happen.
  • Scope: Middleware extends beyond CI/CD into sprint health — blocked work, spilled stories, Jira flow metrics, and AI-generated sprint summaries. CDviz focuses on the full SDLC event stream (build, test, artifact, deploy, incident) with less emphasis on issue-tracker analytics.
  • Event standard: CDviz is built on the CDEvents specification — a CD Foundation project for interoperable CI/CD events. Middleware uses a proprietary data model tied to its own integrations.
  • Observe and act: CDviz events can trigger downstream workflows — the same event stream that drives observability can also drive automation. Middleware is monitoring and reporting only.
  • Visualization: CDviz integrates with Grafana, BI tools, AI agents, and IDP frameworks, giving teams full flexibility. Middleware ships its own built-in dashboard UI, optimised for DORA and sprint metrics.
  • Cost model: CDviz commercial support is priced per organization per month — not per seat — so cost does not scale with team size. Middleware's Standard SaaS tier is $39 per user per month, which grows linearly with headcount.

When to choose CDviz ​

  • You want real-time metrics without polling delays or API rate limits.
  • Data ownership or privacy regulations make vendor-hosted SaaS unacceptable.
  • You are adopting the CDEvents open standard for interoperability across your toolchain.
  • You need events to trigger downstream workflows — not just observe them.
  • You want flexible storage, reporting, or integration with BI tools, AI agents, or IDPs.
  • Team size makes per-seat pricing expensive; you prefer a flat per-org cost (contact us).

When to choose Middleware ​

  • Your primary workflow is sprint-centric: you want Jira flow metrics, sprint reports, and blocked-work detection alongside DORA.
  • You want AI-generated sprint summaries and automated Slack reports out of the box.
  • Your team is small and the free community tier covers your needs.
  • You prefer a built-in dashboard UI rather than operating Grafana separately.

Summary ​

Middleware and CDviz are both open-source Apache 2.0 tools, but they solve adjacent problems. Middleware is a strong choice for engineering managers who want sprint health, Jira flow, and AI-assisted reporting alongside DORA metrics — with a polished built-in UI and a free self-hosted tier. CDviz is the right choice when you need a real-time event-push model, CDEvents interoperability, event-driven automation, and flexible visualization — with flat per-org commercial support available to reduce operational risk.

FAQ ​

Is Middleware open-source? Yes — Middleware is Apache 2.0 licensed and available at github.com/middlewarehq/middleware.

Does Middleware support CDEvents? No. Middleware uses a proprietary data model based on polling GitHub/GitLab/Jira APIs. CDEvents integration is not supported.

Does CDviz support Jira? Yes — CDviz can ingest Jira-sourced events (e.g., issue state changes) via the CDviz Collector, though sprint-level flow metrics are not a current focus.

Is CDviz free? Yes — Apache 2.0. Infrastructure costs only when self-hosted; optional commercial support is billed per organization, not per seat.
