123 Dyno Beta

The fastest and most feature rich autoscaling solution for web and worker dynos. Starting at $0/mo.

Lightning Fast Autoscaling

Scale up fast and don’t lose customers to slow server response times under peak load. 123 Dyno scales up your application in under a second of peak traffic and at regular intervals all the way down to 5 seconds. Compared to Heroku’s base 60 second scaling intervals and other solutions 15 second scaling intervals, this is the fastest you can get.

Open New Possiblities

Open new autoscaling possibilities that no other addon or Heroku provides. Scale by an array of response times, dyno cpu usage, queue times, memory usage, and more. View all of these metrics easily in one overview and tune your dyno formations to exactly how robust or efficient you would like them to be.

Web URL Blocklist

Remove outlier URLs that throw off scaling statistics, like socket.io requests or long-running file uploads. Save money and stop increasing your formation for bad response time data.

Maximum Utilization

Be CPU greedy with each dyno or choose fast scaling lightning quick response times. Tune your autoscaling to the number of dynos you need, scale up under load and down during quiet periods automatically.

Free Beta Period

123 Dyno’s Beta period is completely free for early adopters and will remain so for 2 months after it releases to general availability.

Just Install and Configure

123 Dyno operates across all languages and stacks, no additional code necessary. Scale your formation, queues, web, and worker processes easily on Heroku premise.

Load Analytics

Get insights into your application under load, how your dyno formation responds to traffic, which processes are using the most CPU, and which are running to specification. More than just brute autoscaling, 123 Dyno gives you the DevOps tools to analyze and make your app more performant, saving you more money.

Email Load Alerts

Gain a new sense of your application under load with configurable alerts for web and worker dynos for any metric. Be alerted of load spikes and adjust formation as necessary.
