You can migrate from Heroku in just one click with an AI agent. Kuberns reads your repository, detects your stack automatically, and deploys your app with zero downtime. No Dockerfile. No YAML. No infrastructure work.
Heroku entered sustaining engineering mode in February 2026. No new features, no new enterprise contracts, security patches only. At the same time, a realistic production stack on Heroku (two Standard dynos, Heroku Postgres, Redis Mini, and a couple of add-ons) runs $200 to $500 per month before you have written a line of code for scale. The Stack Overflow 2025 developer survey reported that 38 percent of current Heroku users are actively evaluating a migration within 12 months.
Most migration guides send you toward Kubernetes or a VPS. Both require DevOps work you did not sign up for. This guide covers the fastest path off Heroku: what to audit first, how to move your database safely, and how to go live on Kuberns with zero downtime.
Why Teams Are Leaving Heroku in 2026
Kuberns is the managed PaaS built for exactly the team that is leaving Heroku: a developer or small team that wants the git-push simplicity of Heroku without the bill, without the feature freeze, and without the operational overhead.
No Dockerfile. No YAML. No config files.
Kuberns uses Agentic AI to read your repository, detect your language and framework automatically, select the correct build command, and deploy your app. If your app runs on Heroku today, it runs on Kuberns without any changes to your codebase. No Procfile dependency, no buildpack lock-in.
Zero-downtime migration built in
Kuberns handles the cutover automatically. Health checks run against the new version before any traffic is routed to it. If the health check fails, traffic stays on the current version. You do not need to manage DNS timing or manual rollback procedures. The platform does it.
Instant rollback on every deploy
Every push to your connected branch triggers an automatic redeploy. If the new build fails a health check, Kuberns rolls back to the previous version automatically, with no manual intervention required. You are never one bad deploy away from a production outage.
Managed Postgres, Redis, and environment variables natively
Kuberns provides managed PostgreSQL and Redis as first-class services, not third-party add-ons. Your environment variables are encrypted and injected securely at both build time and runtime. No add-on marketplace, no per-addon billing surprises.
Up to 40 percent less than equivalent Heroku dynos
Kuberns is built on AWS and passes through infrastructure pricing at scale. Two Standard-1X equivalent dynos, managed Postgres, and Redis on Kuberns cost significantly less than the same stack on Heroku.
Actively developed with AI-native deployment at its core
Heroku is in sustaining mode. Kuberns ships features. The Agentic AI layer that auto-detects stacks, manages scaling, and handles deployments is actively improving. You are not migrating to another platform that will freeze in two years.

How to Migrate from Heroku to Kuberns in One Click
Step 1: Connect Your GitHub Repo
Sign up on Kuberns and connect your GitHub account. The Agentic AI scans your repository immediately. It detects your language and framework, reads your build configuration, identifies your runtime version, and selects the correct build command without any input from you. Node.js, Python, Java, PHP, Go, Ruby, and more are all supported. No Dockerfile. No Procfile dependency.
Step 2: Add Your Environment Variables
Paste in the environment variables you exported from your Heroku app. Database URL, API keys, secrets, Redis connection string. Kuberns encrypts them and injects them securely at both build time and runtime. The same variables your Heroku app depended on work as-is on Kuberns. No export commands, no risk of secrets ending up in your codebase.
Step 3: Click Deploy
The Agentic AI takes over. It runs your build, executes health checks against the new version before routing any traffic, provisions an HTTPS certificate, and enables zero-downtime CI/CD automatically. Your app is live in under 5 minutes. Every subsequent push to your connected branch triggers an automatic redeploy with health-check-gated cutover and instant rollback if the new version fails.
Once your app is running on Kuberns and all health checks are passing, update your DNS to point your domain at Kuberns. Keep your Heroku app running until you have confirmed stability under real traffic. Once confirmed, you can let the Heroku app wind down.

Conclusion
Heroku is in sustaining mode, bills are high, and the platform is not being developed. The migration is not a question of whether, only when and where.
Kuberns is the fastest exit. It gives you the same git-push developer experience Heroku built its reputation on, without the cost, without the feature freeze, and without a Dockerfile or YAML file between you and a live deployment. Connect your repo, add your env vars, and your app is live with zero downtime in under 5 minutes.
