   Heroku moves to sustaining engineering

   No new features. "Enterprise Account contracts will no longer be offered to new customers." No change for existing customers, per Heroku.

   Heroku, 2026

Our view: changes usually reach new customers first, existing customers later. Heroku, Cloud9 and Fly.io fit the pattern; no study measures it.

Moving off Opsgenie

Atlassian's destination is Jira Service Management, where Opsgenie's alerting and on-call features now live. Existing customers can use Opsgenie until April 5, 2027; after that it shuts down and data not moved is deleted.

Atlassian, Opsgenie migration

Our view: plan for the deadline as a migration project. Export alert rules, schedules and escalation policies early, and compare alternatives before picking the default.

What to do

1. Keep a written exit plan per platform: destination, data export path, rough effort.
2. Prefer portable parts: containers, standard Postgres, your own registrar and DNS.
3. Watch vendor blogs for "new customers only" changes. Treat them as an early warning for existing customers.

Questions

What replaces Opsgenie?

Atlassian's destination is Jira Service Management, where Opsgenie's alerting and on-call features now live.

Is Heroku being discontinued?

No. In February 2026 Heroku moved to sustaining engineering: no new features, and Enterprise Account contracts are no longer offered to new customers.
