Heroku's new dynos are generally available.
There are now some entry level pricing options available with: - Free Dynos: up to 18 hours of activity in a 24 hour period, 1 web dyno, 1 worker dyno, 1 one-off dyno started by Heroku run or Heroku scheduler. They sleep automatically. - Hobby Dynpos: This is perfect for developing applications on, whether it is a feature branch based app or just getting started, it provides 24x7 uptime with 512mb of RAM, no sleeping and are $7 per dyno per month. They used to start at $36. You can build apps with 1 hobby dyno per process type, up to 10 process types. You can scale from there.
The other semi change is the “Professional dynos”. - These come with “pro” features that will make your app production ready, including scaling vertically and horizontally, metrics, preboot and fast builds. Starting at $25 per dyno per month at 512MB and up. - It does mean the traditional free dyno that would run 24x7 as long as it had traffic is now gone.
Existing paid applications can be migrated anytime between now and Jan 31, 2016. Most apps should see a saving when making the switch, so it is definitely worth evaluating sooner rather than later.
To ease the transition, until August 15th, 2015, free dynos will receive warnings when they are active for more than 18 hours out of the 24 hour period. After August 15th, the dynos will be required to “recharge”, basically become offline for 6 hours.
This is a great change in my opinion from the previous pricing, as it provides some more lower cost entry points with the hobby plans which I know a lot of people have been wanting, as well as myself.
