Bunnyshell vs AWS Proton.

AWS Proton reaches end of life October 7, 2026. Bunnyshell runs your existing CloudFormation and Terraform natively — no rewrite needed. Ephemeral environments, cost controls, remote dev, AI sandboxes, and Git ChatOps included.

How the two platforms compare across the dimensions that matter most.

TL;DR

AWS Proton is a managed platform engineering service reaching end of life on October 7, 2026. Bunnyshell is a cloud-agnostic Environments as a Service platform that runs your existing CloudFormation and Terraform code natively. Migration effort is low — your IaC stays as-is. Bunnyshell adds ephemeral environments, cost controls, remote development, AI sandboxes, and Git ChatOps that Proton never offered.

01

Zero-rewrite migration.
Your IaC stays as-is.

CloudFormation templates become GenericComponents. Terraform modules become native Terraform components. Your existing IaC code stays exactly as-is — no rewrite, no refactoring. Proton's environment and service templates map directly to a unified bunnyshell.yaml. schema.yaml parameters become template variables. Migration effort is low because Bunnyshell speaks the same IaC languages Proton did.

Multi-cloud freedom.
Not locked to AWS.

AWS Proton only works with AWS services. Bunnyshell deploys to any Kubernetes cluster — AWS EKS, GCP GKE, Azure AKS, or on-prem. You keep full control over infrastructure, networking, and compliance. No single-cloud lock-in. Teams running multi-cloud or hybrid architectures get a single pane of glass for all environments.

What Proton never had.
Everything else you need.

Ephemeral environments per PR with auto-create and auto-destroy. Remote development with file sync and SSH modes for VS Code and JetBrains. AI Sandboxes with Firecracker isolation. Git ChatOps with /bns:deploy commands from PR comments. Built-in DORA metrics. Cost controls with availability rules, TTL, and scheduled stop/start. AWS Proton offered none of these.

What else Bunnyshell
does that Proton doesn't.

Bunnyshell covers the full environment lifecycle. Here are capabilities AWS Proton never offered.

Ops

API-Driven Operations

Full REST API and a dedicated CLI (bns) for automating environment lifecycle. Create, update, deploy, and destroy environments programmatically. Integrate with any CI/CD pipeline or custom tooling.

Security

Built-in RBAC

Policies, Roles with label-based scoping, and Teams — all built into Bunnyshell. No need to configure AWS IAM policies. Fine-grained access control for environments, projects, and organizations.

Cost

Cost Management

Availability rules, TTL, scheduled stop/start, and Kubecost-powered per-environment cost reporting. Sleeping environments cost $0. Proton had no cost controls beyond manual AWS resource management.

Sync

Template Sync

Unified bunnyshell.yaml replaces Proton's separate environment and service templates. Drift detection shows when environments diverge from templates. Built-in diff editor to review and reconcile changes.

Deploy

Parallel Deployment

Components deploy in parallel with explicit dependsOn ordering. No more sequential provisioning. Complex environments with 20+ components deploy in minutes, not hours.

Data

Data Seeding

Seed databases from Container, RDS, Cloud SQL, Neon, or PlanetScale snapshots. Every ephemeral environment gets production-like data automatically. Proton had no data seeding capabilities.

After October 7, 2026, AWS Proton will no longer manage your infrastructure. Your underlying AWS resources (ECS, Lambda, etc.) will continue running, but you lose the Proton management layer — no more template updates, no more automated deployments through Proton, no more service syncs. You need a replacement platform to manage environment provisioning and lifecycle.
