Bunnyshell vs Heroku.
Environments as a Service — preview, production, AI sandboxes, remote dev, and more. All pay-per-minute on your own Kubernetes clusters. Heroku is a classic PaaS with managed dynos, buildpacks, and per-dyno pricing.

How the two platforms compare across the dimensions that matter most.
Bunnyshell is a Kubernetes-native Environments as a Service platform — preview, production, AI sandboxes, remote dev, DORA metrics, and pay-per-minute pricing on your own cloud. Heroku is a well-established PaaS with managed dynos, buildpacks, Heroku CI, and managed Postgres/Redis. Bunnyshell wins on Kubernetes support, BYOC, AI sandboxes, remote dev, multi-stack flexibility, and cost transparency at scale.

Bunnyshell AI Sandboxes
powered by hopx.
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. AI IDE Workspaces with persistent cloud VMs. Heroku offers managed inference endpoints as add-ons — Bunnyshell gives AI agents real infrastructure to run in.
Bunnyshell runs on
your Kubernetes clusters.
Bunnyshell deploys to your own AWS, GCP, or Azure Kubernetes clusters (BYOC). You keep full control over infrastructure, networking, and compliance. Heroku runs on Salesforce-managed infrastructure with a proprietary dyno runtime — no Kubernetes, no Helm, no Terraform. Teams outgrowing Heroku often face a costly replatforming effort. Bunnyshell is K8s-native from day one.
Bunnyshell pricing:
pay for what you use.
$0.007 per minute. Sleeping environments cost $0. No per-seat pricing, no dyno limits. Heroku charges per-dyno: Eco at $5/mo, Basic at $7/dyno, Standard-1X at $25/dyno, and Performance-M at $250/dyno — costs compound fast with multiple services. At 20 microservices on Standard-1X dynos, Heroku runs $500/mo in compute alone before add-ons.
What else Bunnyshell
does that Heroku doesn't.
Bunnyshell covers the full environment lifecycle. Here are capabilities Heroku does not offer.
Bring Your Own Cloud
Deploy to your own AWS, GCP, or Azure Kubernetes clusters. Keep data in your VPC, meet compliance requirements, and avoid vendor lock-in. Heroku runs exclusively on Salesforce-managed infrastructure.
Multi-Stack Support
Bunnyshell natively supports Docker Compose, Helm, Kubernetes manifests, and Terraform — mixed in a single environment. Heroku uses buildpacks and a proprietary runtime with limited Docker support.
Built-in DORA Metrics
Deployment frequency, cycle time, change failure rate, MTTR — tracked natively. Measure the impact of your environment strategy.
Drift Management
Detect when environments diverge from templates. Built-in diff editor to review changes. Keep staging in sync with production automatically.
Git ChatOps
Manage environments from PR comments: /bns:deploy, /bns:stop, /bns:delete. Works with GitHub, GitLab, Bitbucket.
Remote Development
Code in VS Code or JetBrains, run in the cloud. Real-time file sync, step-through debugging, port forwarding. No local dependency conflicts.

For teams running multiple services, typically yes. Heroku charges per-dyno — Standard-1X is $25/dyno/month and Performance-M is $250/dyno/month, plus add-on costs for Postgres, Redis, etc. Bunnyshell charges $0.007/minute with no user or cluster limits, and sleeping environments cost $0. Teams with variable workloads or many environments typically see significant savings.
