What Is Cloud 66
Cloud 66 is a DevOps-as-a-Service platform that automates deploying and operating applications on a customer's own cloud infrastructure rather than hosting workloads on a shared, vendor-owned platform. Users connect an AWS, Google Cloud, Azure, DigitalOcean, or Linode account, and Cloud 66 provisions servers, configures networking, and manages ongoing deployments, scaling, and database operations on top of it.
The platform grew out of founder Khash Sajadi's frustration with expensive, restrictive PaaS offerings and overly complex configuration-management tools like Chef, and it was originally built to bring Heroku-style simplicity to Ruby on Rails deployments on a customer's own servers before expanding to Node.js, Docker, and Kubernetes workloads.
Deployment and Operations Features
Cloud 66 supports zero-downtime deployments using blue-green and canary release strategies, hosted Docker build servers with an integrated multi-architecture container registry, and full managed database support including automated backups and replication. Autoscaling can be driven by real application metrics such as CPU, memory, queue backlog, and web response time rather than simple fixed thresholds.
The platform also creates automatic preview environments for git branches, tags, and pull requests, letting teams review changes in a live environment before merging, and it provides SSL automation and custom network and firewall configuration out of the box.
Cloud 66 Pricing Tiers
Cloud 66 offers a free plan limited to one deployment server and one static site, paid Developer, Team, and Business plans priced by the number of servers and static sites included (roughly 23, 47, and 80 dollars per month respectively), and a custom-priced Enterprise tier for organizations running fifty or more servers that adds dedicated account management and on-premises deployment options.
Annual billing offers roughly a 20 percent discount versus monthly billing, and additional servers, static sites, team members, and build minutes can be added a la carte on any paid plan.
Key Features
Multi-cloud deployment — Deploys applications directly into a customer's own AWS, Google Cloud, Azure, DigitalOcean, or Linode account rather than a shared hosting platform.
Zero-downtime, blue-green and canary deployments — Supports advanced release strategies that avoid downtime during application updates.
Hosted Docker build servers and container registry — Builds Docker images on hosted infrastructure with support for multiple CPU architectures and an integrated registry.
Managed databases with backups and replication — Provisions and manages database engines with automated backups and replication for high availability.
Metric-driven autoscaling — Scales servers and services based on real application metrics such as CPU, memory, queue backlog, and response time.
Preview environments for branches and pull requests — Automatically spins up and tears down environments tied to git branches, tags, and pull requests.
SSL automation and network configuration — Automates certificate provisioning and lets teams configure custom networking and firewall rules.
Static site hosting — Supports deployment and hosting of static site generator output alongside full application stacks.
Pros & Cons
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
Pricing
Free $0 per month
Developer $23 per month
Team $47 per month, billed annually
Business $80 per month
Enterprise Custom custom
