AWS `ap-south-1` region support

With ap-south-1 (Mumbai), Sprinters now supports AWS' most cost-effective region, by far, for x64 AMD and arm64 instances, with certain instance types costing less than half of what they cost in other regions.

AWS `r5`, `r5a`, `r6a`, `r6i` and `r7a` instance support

Need memory-optimized x64 instances with high spot savings? Sprinters has you covered with r5, r5a, r6a, r6i and r7a instances.

AWS `eu-west-2` region support

You can now run your jobs in the UK by choosing the eu-west-2 AWS region (London).

Faster-booting `-slim` and `-minimal` images with lower EBS costs

Faster-booting runners? Much lower EBS costs? Choose both with our new -slim and -minimal images.

AWS `c5`, `c5a`, `c6a`, `c6i` and `c7a` instance support

Need compute-optimized x64 instances with high spot savings? Sprinters has you covered with c5, c5a, c6a, c6i and c7a instances.

Size optimization for temp volume

Not sure how large your temp volume should be? You can now see its actual usage at the end of every job run, allowing you to right-size it and lower your EBS costs with confidence.

AWS `c6g`, `c7g`, `c8g`, `r6g`, `r7g` and `r8g` instance support

Need more compute, but not more RAM? Or more RAM, but not more compute? You can now right-size your AWS arm64 runners by picking compute-optimized c6g, c7g and c8g instances and RAM-optimized r6g, r7g and r8g instances.

Free for public repositories

Sprinters is now free for public repositories. You can now combine this with the AWS free tier to get AWS runners at zero cost.

Adjustable root, swap and temp volume performance

In addition to configuring the size of the swap and temp volumes, you can now also configure the performance of the root, swap and temp volumes. High-performance volumes significantly reduce run times for I/O-bound jobs.

Simplified per job pricing

We've simplified Sprinters' pricing to make it both clearer and more predicable. Sprinters now costs $0.01 per job for any number of vCPUs, any number of build minutes and any number of concurrent jobs.

AWS `m5`, `m5a`, `m6a`, `m6i` and `m7a` instance support

Looking for the lowest-cost per hour general purpose x64 instances that don't depend on CPU credits? Sprinters now has you covered with m5, m5a, m6a, m6i and m7a instances.

AWS instance profile support

You can now access resources in your AWS account from your runners without the need to store long-lived AWS credentials as GitHub Actions secrets. By appending an IAM instance profile name to your label, your runner instance will automatically have AWS credentials available with the permissions of the IAM role linked to that instance profile.

AWS `c7i`, `c7i-flex` and `r7i` instance support

Need more compute, but not more RAM? Or more RAM, but not more compute? You can now right-size your AWS x64 runners by picking compute-optimized c7i and c7i-flex instances and RAM-optimized r7i instances.

`ubuntu-22.04-arm` image support

Just like for the Ubuntu 24.04 one, you can now also choose the ubuntu-22.04-arm image for arm64 runners, which is identical to the official one from GitHub.

AWS `ap-northeast-1` and `us-west-2` region support

You now have two more AWS regions to choose from: ap-northeast-1 (Tokyo) and us-west-2 (Oregon).

`ubuntu-24.04-arm` image support

Arm64 runners now come with full Ubuntu support using the new ubuntu-24.04-arm image. This image is identical to the official one from GitHub.

AWS `m6g`, `m7g` and `m8g` instance support

Good news for arm64 users! You can now launch your runners on AWS using m6g, m7g and m8g instances.

Simplified CloudFormation-based AWS account setup

Getting set up is now easier with our new Cloudformation-based setup which eliminates a number of manual steps.

AWS `m7i-flex.12xlarge` and `m7i-flex.16xlarge` instance support

You can now launch your runners on AWS using m7i-flex.12xlarge and m7i-flex.16xlarge instances.

AWS `eu-west-1` region support

You can now launch your runners in the eu-west-1 (Ireland) AWS region.

Further restrict AWS IAM policy by default

We believe in defense in depth and with our new IAM policy we enforce further restrictions on the actions Sprinters can perform on your AWS account.
