You do not have to leave Heroku immediately. On February 6, 2026, Heroku said it was moving to a sustaining engineering model while continuing to support existing production workloads. Whether to stay or migrate is a workload and risk decision: inventory what your app depends on, compare realistic destinations, rehearse the data move, and plan a controlled cutover with a workable rollback.
What Heroku’s sustaining engineering announcement means
Heroku said its sustaining engineering focus would be stability, security, reliability, and support. The announcement said applications, pipelines, teams, and add-ons were unaffected, and that customers paying by credit card through the dashboard would see no change. It also said new Enterprise Account contracts would no longer be offered, while existing Enterprise subscriptions and support contracts would continue to be honored and could renew. These are statements from the announcement on its publication date, not guarantees about future product or commercial changes. Read Heroku’s announcement.

The practical implication is not “migrate now at any cost.” If Heroku meets your current needs, staying while you assess options may be reasonable. If a future change, contract renewal, operational requirement, or business continuity concern makes the risk unacceptable, start migration planning before a deadline forces a rushed move.

Which Heroku alternatives should you evaluate?
Start with candidates, not rankings. Fly.io’s September 2026 alternatives overview names Render, Railway, DigitalOcean App Platform, Vercel, Netlify, Platform.sh (now Upsun), Northflank, and Fly.io. Render’s 2026 migration guide also discusses AWS and GCP for teams willing to take on more infrastructure responsibility. The Fly.io overview is written by a provider included in its own list, so treat it as a shortlist—not an independent comparison or proof that one option is best. See Fly.io’s alternatives overview; see Render’s decision guide.

How to choose a destination for your app
Compare platforms against the app you actually run, not just its web dyno or headline monthly price. A migration can change how processes are deployed, where state lives, how services communicate, and who is responsible for operating them.
- Processes: Can the destination run every web process, background worker, scheduled task, and one-off task you use today? Map each Procfile process type, including non-web processes, to a supported target service.
- Stateful dependencies: Check the destination’s database, queue, file storage, backup, and recovery options. Decide which dependencies move with the app and which can remain external.
- Build and deploy: Determine how much of your Git-based workflow carries over, and whether you can retain buildpacks or need an explicit container definition.
- Network and runtime needs: Validate regions, private networking, long-lived requests or connections, and integrations with external systems. A successful build is not proof that the app’s runtime behavior will work.
- Requirements and ownership: Check compliance and support needs, and decide how much infrastructure the team wants to operate directly.
- Total workload cost: Estimate web and worker services, database, staging, networking, backups, and support together. Railway describes its billing as usage-based on aggregate resource use, in contrast to Heroku’s per-dyno monthly model; that is Railway’s own comparison, not an independent price study. Recalculate using current official pricing and your actual usage, always-on needs, and staging footprint. Railway’s billing comparison.
Before committing, make a dependency map: for each process or service, record its inputs, data stores, secrets, network access, owner, and recovery plan. This catches dependencies that a simple list of app names misses.
How to migrate from Heroku without losing data
Move in stages, with the database write boundary treated as a deliberate operational decision. Render recommends moving stateless compute first, queues second, and data and DNS last, alongside a written rollback plan. That order is a useful starting point, but adjust it when service coupling requires another sequence. Render’s 2026 migration guide.

Record every app and Procfile process type; config variable and secret; domain and certificate; add-on; scheduled job; queue; persistent file; integration; database extension; and external system that connects to the database. Render’s migration guide specifically maps non-web Procfile processes to target background workers and calls out Postgres and Key Value datastores as migration items. Render’s Heroku migration documentation.
- Choose the destination against that inventory. Confirm support for actual process types and stateful dependencies. Decide what moves together, what remains external, and what must be changed in application configuration. Do not select on advertised entry pricing alone.
- Provision dependencies, then deploy. Create needed target datastores before deploying apps that depend on them; Render recommends this so the apps can connect on their first deployment. Configure secrets, health checks, observability, backups, and a production-like test environment before production cutover. Render’s migration documentation.
- Rehearse the database transfer. Heroku’s Postgres export documentation describes PGBackups capture, download, and restore using PostgreSQL’s
pg_dump. Heroku says PGBackups is intended for moderately loaded databases up to 20 GB; larger databases should use its separate guidance for larger databases. In a rehearsal, confirm PostgreSQL version compatibility, extensions, roles, ownership, encoding, connection limits, and restore duration. Heroku Postgres import and export documentation. - Define the write boundary. A dump-and-restore snapshot does not include source changes made after the dump. For that method, set a write freeze and maintenance window, or choose another replication approach explicitly supported by both source and destination. After restoring, verify record counts and application behavior before allowing production writes to the new database. Heroku’s migration preparation guidance.
- Move in controlled stages. A common sequence is stateless compute, queues, then data and DNS. Make dependencies explicit and avoid concurrent writes to two databases unless the application is designed to support them. Test the app against the target datastore and services before directing users to the new environment. Render’s 2026 decision guide.
- Keep rollback actionable. Write down the rollback deadline, triggering conditions, decision-maker, DNS reversal procedure, and how to reconcile writes created after cutover. Keep the old database intact through the agreed validation period. Once production writes go to the new database, rollback involves data reconciliation—not just switching DNS back.
What to verify before declaring the migration complete
- Every web, worker, scheduled, and one-off process has an intentional destination and has been exercised.
- Secrets, domains, certificates, integrations, scheduled work, and service connections function in the target environment.
- The database restore has been rehearsed, and the team has verified compatibility and data integrity against the application’s real behavior.
- Monitoring, backup and recovery procedures, and access responsibilities are understood by the people who will operate the new setup.
- The cutover owner knows when writes move, what conditions stop the change, and how the team will reconcile data if rollback becomes necessary.
These checks distinguish a deployed copy from an operational migration. Do not close the migration while rollback still depends on undocumented steps or an untested database restore.
