Heroku Enters Sustaining Engineering Mode: What It Means and When to Consider Alternatives

In February 2026, Salesforce announced that Heroku is transitioning to a sustaining engineering model. No new features, no new Enterprise contracts for new customers, and a strategic pivot toward AI-driven products instead of platform development.

For the thousands of teams that built their deployment workflows around Heroku, this raises a practical question: what now?

This article breaks down what the announcement actually means, who should consider migrating, and how DeployHQ fits as a deployment layer — especially if you deploy to your own servers or cloud infrastructure.

What Heroku's Sustaining Engineering Actually Means

Heroku's official update and March 2026 follow-up confirm the following:

• No new feature development. The roadmap is defensive — security patches, stability fixes, and infrastructure maintenance only.
• Enterprise contracts are no longer offered to new customers. Existing Enterprise customers can renew, but Salesforce is not onboarding new ones.
• Credit card customers are unaffected for now. If you pay via the Heroku dashboard, pricing and billing remain the same.
• No sunset date announced. Heroku could run in this mode for years, but long-term certainty decreases over time.

The March 2026 update framed this as a mission to provide the most stable, secure, and reliable environment for your apps and data — but conspicuously dropped any mention of innovation or feature roadmap.

In software terms, sustaining engineering is the phase before end-of-life. It does not mean Heroku is shutting down tomorrow. It means the platform has stopped evolving, and teams planning for the next 2-5 years should factor that into their infrastructure decisions.

Who Should Consider Moving — And Who Shouldn't

Not every Heroku customer needs to migrate immediately. Here is a practical framework:

Stay on Heroku (for now) if:

• Your app is stable, low-traffic, and doesn't require new platform features
• You are on a credit card plan with no Enterprise dependencies
• You have no compliance requirements that demand an active development roadmap from your platform vendor
• Migration cost exceeds the risk of remaining on a sustaining platform

Start planning a migration if:

• You need features Heroku will never ship (private networking, advanced build controls, regional deployment)
• You are an Enterprise customer whose contract renewal terms may change
• Your compliance or security team requires vendors with active development commitments
• You are scaling and hitting Heroku's known limitations (30-second request timeout, daily dyno restarts, limited build customisation)
• You deploy to your own servers, VPS, or cloud infrastructure — Heroku was always an awkward fit for this

Why DeployHQ Is Worth Considering

DeployHQ is not a Heroku replacement in the traditional PaaS sense. It does not host your application or manage your infrastructure. Instead, it handles one thing exceptionally well: getting your code from a Git repository to your servers, reliably and automatically.

This distinction matters. Many Heroku users — particularly those deploying PHP, Ruby, Python, or Node.js applications — do not actually need a full PaaS. They need a deployment pipeline that connects to their existing servers.

Here is where DeployHQ fits:

Git-Native Deployment

DeployHQ connects directly to GitHub, GitLab, and Bitbucket. Push to a branch and your code is deployed — similar to Heroku's git push heroku main workflow, but to any server you control.

Zero Downtime Deployments

Heroku handles this behind the scenes with its dyno management. With DeployHQ, zero downtime deployments work by maintaining atomic release directories on your server. New releases are prepared in isolation, symlinked on success, and rolled back instantly on failure.

One-Click Rollback

One of Heroku's best features was easy rollbacks. DeployHQ provides one-click rollback to any previous deployment — no CLI commands, no release slugs to manage.

Build Pipelines

If your application needs a build step (compiling assets, installing dependencies, running tests), DeployHQ's build pipelines run these steps before deployment. Similar to Heroku's buildpacks, but configurable to match your exact workflow.

Deploy Behind Firewalls

Unlike Heroku, which is limited to its own infrastructure, DeployHQ can deploy behind firewalls using network agents — reaching servers in private networks, corporate environments, or air-gapped infrastructure.

Docker Builds

For teams moving toward containers, DeployHQ supports Docker builds as part of the deployment pipeline — build, test, and deploy container images to any registry or server.

Migration Checklist: Heroku to DeployHQ

If you decide to move, here is a practical migration path:

1. Audit Your Heroku Setup

Before changing anything, document what you have:

• Application type: Web app, API, worker process, or scheduled job?
• Language/framework: PHP, Ruby, Python, Node.js, Go?
• Add-ons: Which Heroku add-ons do you depend on? (Postgres, Redis, logging, monitoring)
• Environment variables: Export your config vars (heroku config -s > .env)
• Build process: What does your Procfile and buildpack do?

2. Provision Your Server

DeployHQ deploys to servers you control. You will need:

• A VPS or cloud server (DigitalOcean, AWS EC2, Linode, Hetzner, or your own hardware)
• SSH access configured
• Your runtime environment installed (PHP, Node.js, Ruby, Python)

For teams deploying WordPress, Laravel, Rails, Django, or Express apps to a VPS, this is a natural fit. DeployHQ's deployment targets support SSH/SFTP, Amazon S3, Rackspace Cloud Files, and more.

3. Set Up DeployHQ

1. Sign up for DeployHQ
2. Create a project and connect your Git repository
3. Configure your server as a deployment target
4. Set up environment-specific config files to replace Heroku's config vars
5. Add build pipeline steps if needed (e.g., npm install && npm run build)
6. Configure automatic deployments to trigger on push

4. Migrate Your Data

• PostgreSQL: Export with pg_dump, import to your new database server
• Redis: Export with redis-cli --rdb or use BGSAVE
• File storage: If you used ephemeral storage on Heroku, move to S3 or equivalent

5. Update DNS and Go Live

Point your domain to your new server, run smoke tests, and monitor with your preferred observability stack. DeployHQ integrates with Slack, Discord, and other notification services to keep your team informed during the transition.

DeployHQ vs Heroku: A Practical Comparison

Capability	Heroku	DeployHQ
What it does	Hosts and runs your app (PaaS)	Deploys code to your servers
Server management	Fully managed	You manage your servers
Git push deploys	Yes	Yes
Rollback	Via CLI (heroku rollback)	One-click in dashboard
Build steps	Buildpacks (limited customisation)	Fully configurable build pipelines
Zero downtime	Preboot (paid plans)	Included on all plans
Deploy to own servers	No	Yes (SSH, SFTP, S3, and more)
Private network support	No	Yes (via network agents)
Docker support	Container registry	Docker build pipelines
Integrations	Heroku add-ons marketplace	GitHub, GitLab, Bitbucket, Slack, Sentry, and more
Pricing	Starts at $5/mo per dyno	Starts at $4/mo for 10 projects
Active development	Sustaining engineering only	Active feature development

What DeployHQ Does Not Replace

To be transparent: DeployHQ is not a drop-in Heroku replacement for every use case.

• App hosting: DeployHQ does not run your application. You need your own server or hosting provider.
• Managed databases: Heroku Postgres was convenient. You will need to self-manage or use a managed database service (AWS RDS, DigitalOcean Managed Databases, PlanetScale, Neon).
• Add-on marketplace: Heroku's add-on ecosystem has no direct equivalent. You will integrate services directly.
• Scaling: Heroku's dyno scaling is automatic. With your own servers, you handle scaling yourself (or use auto-scaling from your cloud provider).

For teams that want the full PaaS experience, platforms like Render, Railway, or Fly.io are closer Heroku replacements. DeployHQ targets a different — and arguably larger — audience: developers who already have servers and need a reliable way to deploy to them.

The Bigger Picture

Heroku's move to sustaining engineering is part of a broader industry trend. Salesforce acquired Heroku in 2010 for $212 million, and the platform defined a generation of developer experience. But priorities shift, and Salesforce's investment is now directed toward enterprise AI.

For developers, the lesson is practical: avoid single points of failure in your deployment infrastructure. Whether you stay on Heroku for now or migrate to a combination of your own servers and a deployment tool like DeployHQ, the goal is the same — control over how and where your code runs.
