Autoscaling and monitoring via CPU, memory, queue, and response times. Starting at ~$0.007/hour.

Overview Autoscaling Analytics Load Alerting Transparent Logs
The Autoscaling Add-On For Heroku

123 Dyno provides autoscaling that handles load faster and cuts your bill. It provides a 12x speed upgrade with more options than most cloud providers including CPU, memory, queue, and improved response time scaling methods. It was designed to allow intelligent handling of load to fit any situation with extended DevOps monitoring to match.

What 123 Dyno Offers

123 Dyno extends past the Heroku concept of simplicity in single target M95 autoscaling and adds critical tools and monitoring to intelligently manage load.

12x Autoscaling Speed Increase

It can take Heroku up to 60 seconds to trigger an autoscaling event, leading to slow servers under load, this is better than starting up a box but 123 Dyno supercharges this. Autoscale within seconds of traffic spikes and keep up with as short as 5 second scaling intervals, faster than Heroku or any other add-on.

CPU Load & Memory Autoscaling

Autoscale via CPU/memory load instead of response times to gain maximum value for each dynos compute power. Strapi, a Headless CMS that runs 123 Dyno’s Heroku blog conservatively gets around 800 req/s before maxing out CPU on a shared Standard-1x dyno.

Consistent Response Time Autoscaling

Autoscale by a strictly defined range you want your application to be in. Downscale when metrics fall below that range and upscale when metrics increase past them. Options for autoscaling speed, URL pruning, and sample windows included to attain accurate smooth response time scaling you won’t find anywhere else.

Install and Configure in Minutes

The add-on can be installed across all languages and stacks, no additional code necessary. Autoscale and monitor your web and worker processes easily on Heroku premise. Install free today.

Extended DevOps Dashboard

Each app responds to load uniquely, 123 Dyno gives full view of the situation for quick DevOps. Take in response times, queue times, longest running paths, CPU load, and memory utilization to quickly pinpoint issues with your dyno and resolve them.

Transparent Logs

123 Dyno offers transparent raw metric and autoscaling logs so you can see exactly how the independently partnered solution is working.

Extended Load Alerting

Get out of your cyberpunk routine and gain a new sense of your application under load with configurable email alerts for any of the available metrics and dyno quantities. Automatically monitor your app so you can spend more time developing and less time on DevOps.

Worker Process Autoscaling

123 Dyno extends Heroku with CPU and Memory autoscaling to worker dynos, opening new doors of on-demand computation power on Heroku, no code required at all.

Intelligent Savings

Gain the tools to take control of what your paying for compute power, only pay for what you need on Heroku by choosing a method fit for your stack. Stay on Heroku for the ease of use and ecosystem, do some light DevOps work and potentially save tons on your dyno bill.
