Environments as a Service — preview, staging, production, AI sandboxes, remote dev, and full lifecycle management. AWS Cloud9 is Amazon's browser-based IDE running on EC2 instances. Different categories, different capabilities.
Used by engineering teams at
























How the two tools compare across the dimensions that matter most.
Bunnyshell is an Environments as a Service platform — it provisions full-stack environments per PR, manages staging and production, and includes AI sandboxes, remote dev, DORA metrics, and pay-per-minute pricing. AWS Cloud9 is a browser-based IDE backed by EC2 instances — great for quick AWS development, but locked to the Amazon ecosystem and limited to single-user IDE instances. Bunnyshell wins on full-stack environments, multi-cloud support, Kubernetes-native deployment, and AI capabilities. Cloud9 wins on tight AWS service integration and zero-setup AWS access.
| Bunnyshell | AWS Cloud9 | |
|---|---|---|
| Primary purpose | Environments as a Service — full lifecycle management | AWS cloud-based IDE for coding, running, and debugging |
| Ephemeral preview envs | Full-stack clone per PR, auto-create/destroy | No — persistent IDE instances, not per-PR environments |
| Environment provisioning | Auto-provisions namespaces, networking, DNS, TLS per environment | Provisions an EC2 instance with a browser IDE |
| Production environments | Yes — autoscaling, multi-region, zero-downtime | No — development only |
| AI Sandboxes | Yes — Firecracker isolation, ~100ms start, SDK | No |
| MCP Server | Yes — manage envs from Claude, Cursor, Windsurf | No |
| AI IDE Workspaces | Yes — Cursor, Windsurf, Copilot, JetBrains | Amazon CodeWhisperer integration |
| Remote dev environments | Yes — IDE sync, debugging, port forwarding | Yes — browser-based IDE on EC2 |
| Stack support | Compose, Helm, K8s manifests, Terraform | Any language on EC2 (no orchestration) |
| Environment as Code | Single bunnyshell.yaml, dev to prod | No environment-as-code — manual EC2 setup |
| Templates & service catalog | 28+ templates, custom catalog | Pre-configured AMIs only |
| DORA metrics | Built-in (deploy freq, cycle time, MTTR) | Not available |
| Data seeding | Container, RDS, Cloud SQL, Neon, PlanetScale | No |
| Drift management | Auto-detect env divergence from template | No |
| Git ChatOps | /bns:deploy, /bns:stop from PR comments | No |
| CI/CD | Integrates with any CI/CD | Works with AWS CodePipeline, not a CI/CD tool |
| Auto-sleep schedules | Project-level, custom per environment | Auto-hibernate after idle (configurable) |
| Cost tracking | Kubecost-powered per-environment reporting | AWS billing per EC2 instance |
| Pricing model | Per-minute ($0.007/min), unlimited users | Pay for EC2 instance hours + EBS storage |
| Bring Your Own Cloud | Yes — AWS, GCP, Azure (BYOC) | AWS only |
| Kubernetes native | Yes — deploys to your K8s clusters | No — EC2-based |
| Multi-cluster | Yes — manage environments across clusters | No |
| UI / Dashboard | Full platform UI with env lifecycle, logs, metrics | Browser IDE with terminal |
| SOC 2 Type II | Yes | Yes (AWS) |
| ISO 27001 + ISO 9001 | Yes | AWS ISO certifications |
| Cloud lock-in | Multi-cloud BYOC (AWS, GCP, Azure) | AWS only — fully locked to Amazon ecosystem |
AWS Cloud9 gives you a browser IDE backed by an EC2 instance — great for quick coding on AWS, but it doesn't provision multi-service environments. Bunnyshell creates complete full-stack environments per PR with frontend, backend, databases, networking, DNS, and TLS — all auto-configured.
AI Sandboxes with Firecracker isolation and ~100ms cold starts. Execute untrusted code in JS, Python, .NET, Java, or Go. Full SDK with file operations, process control, port forwarding, and snapshots. MCP Server to manage environments from Claude Code, Cursor, or Windsurf. Cloud9 integrates with Amazon CodeWhisperer but has no sandbox isolation or MCP capabilities.
Bunnyshell deploys to your own Kubernetes clusters on AWS, GCP, or Azure — true multi-cloud. Cloud9 is locked to the AWS ecosystem. If you use GCP, Azure, or want to avoid vendor lock-in, Cloud9 is not an option. Bunnyshell gives you infrastructure freedom while managing the full environment lifecycle.
Bunnyshell covers the full environment lifecycle. Here are capabilities AWS Cloud9 does not offer.
Full-stack environment per PR — auto-created on push, auto-destroyed on merge. Cloud9 creates persistent EC2-backed IDEs, not per-PR preview environments.
Deploy to production with autoscaling, multi-region, and zero-downtime. Cloud9 is a development IDE only.
Deployment frequency, cycle time, change failure rate, MTTR — tracked natively. Cloud9 has no deployment metrics.
Seed databases from RDS, Cloud SQL, Neon, or PlanetScale snapshots. Cloud9 has no data lifecycle management.
Sleeping environments cost $0. Kubecost-powered reporting. Cloud9 charges for EC2 even when idle (unless you configure auto-hibernate).
Manage environments from PR comments: /bns:deploy, /bns:stop, /bns:delete. Cloud9 has no PR-based environment controls.


“Manual tests on Argo CD PRs now take me seconds. When you review dozens of PRs a day, that's a game-changer.”

“Automatically created BunnyShell environment based on PRs, speeding up the entire task implementation process.”


“The automation and scalability that Bunnyshell provides complements the DigitalOcean platform, empowering developers to build amazing products.”


“Websites don't die anymore, sales keep growing sustained by state-of-the-art tech scalability. Customers send thank you cards.”

“From a release once in 2-4 weeks to multiple times per week, and nobody's stressed about it.”

“I can count on an integrated platform for managing our infrastructure — capabilities we don't have in-house, at a fraction of the cost.”

“I can do with Bunnyshell and a DevOps person what my clients are doing with 4 DevOps people.”

“Developers want convenience. They expect someone to translate their Docker Compose to the cloud. They're not going to rush to learn Kubernetes.”

“Bunnyshell was the only tool that handled our Helm + EKS setup without asking us to change everything.”

“60+ microservices. Bunnyshell deploys them in parallel and lets us control which ones come first.”
