Cloud 66

Cloudcraft

cacoo.com

Pros

• Genuinely usable free plan with unlimited users, not just a time-limited trial
• Real-time multiplayer editing with built-in video chat reduces the need for separate call tools
• Wide range of supported diagram types in a single product
• Natural fit for teams already using Nulab's Backlog project management tool
• Enterprise plan covers SSO, SCIM, and audit logging for larger, security-conscious organizations

Cons

• Free plan is capped at just six diagram sheets, which active users will exceed quickly
• Per-user pricing on Pro and Team plans can be less predictable for large or fluctuating teams
• Less name recognition outside of Nulab's existing customer base compared with category leaders like Lucidchart or Miro
• Enterprise pricing is not published and requires a custom sales conversation
• Feature parity between Pro and Team tiers is close, which can make plan selection confusing

Cloud 66

Pros

• Deploys directly into the customer's own cloud account rather than a shared vendor platform, avoiding compute lock-in
• Supports a wide range of cloud providers including AWS, Google Cloud, Azure, DigitalOcean, and Linode
• Advanced deployment strategies like blue-green and canary releases are included on paid plans
• Free tier available for small projects and evaluation before committing to a paid plan
• Automatic preview environments simplify reviewing pull requests in a live setting
• Long operating history since 2012 with enterprise customers such as Adobe and the BBC

Cons

• Smaller company (11-50 employees) than large hyperscaler-native deployment tools, which may affect long-term roadmap pace
• Pricing scales with number of servers, which can add up for larger fleets compared to some competitors
• Historically strongest for Ruby on Rails, so framework support depth can vary for newer stacks
• Enterprise pricing is not public and requires a sales conversation
• Less brand recognition than major platforms like Heroku or Render, which can mean a smaller community and fewer third-party guides
• Extra charges for build minutes and storage overage can make cost less predictable at scale

Cloudcraft

Pros

• Automatically generates diagrams from live infrastructure data instead of requiring fully manual drawing
• Distinctive isometric visual style makes diagrams easier to read than flat, generic box diagrams
• Backed by Datadog's financial resources and platform integration since the November 2022 acquisition
• Supports multiple major clouds (AWS, Azure, Google Cloud, Oracle Cloud) plus VMware vSphere, not just AWS
• Free tier available for individuals, with a 14-day free trial and 30-day money-back guarantee on Pro
• Built-in cost estimation overlays help teams see the cost impact of architecture decisions directly on the diagram

Cons

• Pro and Enterprise per-user pricing can add up for larger architecture and platform teams
• As part of Datadog, product roadmap priorities may be shaped by Datadog's broader observability strategy rather than standing alone
• Free plan is limited to individual, non-live-sync-focused use cases for AWS and Azure only
• Live-diagram accuracy depends on granting Cloudcraft read access to cloud accounts, which some security-conscious teams may need to review carefully
• Smaller, focused product team size compared to broader Datadog product lines
• Primarily useful for infrastructure visualization rather than full infrastructure-as-code management or provisioning

• Cross-functional real-time flowcharting — A product and engineering team maps out a new process or system architecture together on a live shared canvas instead of passing static images back and forth.
• Wireframing and UX collaboration — A design team sketches early-stage wireframes and mockups in Cacoo, gathering live feedback via comments and video chat before moving to a dedicated design tool.
• Diagramming inside an existing Nulab workflow — A team already using Backlog for sprint planning adds Cacoo to document system architecture and org charts under the same Nulab account.
