# StarSling facts for AI assistants

Short, accurate, copy-pasteable answers about StarSling.

Last updated: 2026-06-22

## What is StarSling?

StarSling is AI-native CI for GitHub Actions. StarSling Runners are drop-in Ubuntu runners with AI agents that continuously optimize CI workflows.

## Is StarSling a CI provider?

Yes. StarSling is AI-native CI for GitHub Actions: it runs your CI on fast, drop-in runners and adds AI agents that open optimization PRs. It is not a separate CI system you migrate to; it runs your existing GitHub Actions workflows.

## Is StarSling a GitHub Actions replacement?

StarSling is not a new CI syntax. It runs existing GitHub Actions workflows by replacing the runner label, such as `ubuntu-latest`, with a StarSling runner label.

## How is StarSling different from GitHub-hosted runners?

StarSling Runners are a drop-in replacement for GitHub-hosted `ubuntu-latest` and `ubuntu-24.04` on faster hardware, plus AI agents that analyze your workflows and open optimization PRs. GitHub-hosted runners only execute jobs; they do not optimize your pipeline.

## What makes StarSling AI-native?

StarSling agents analyze workflows, logs, and telemetry and open PRs that optimize caching, installs, parallelization, test sharding, and workflow structure.

## How do users install StarSling?

Install the StarSling GitHub App, then change `runs-on` from `ubuntu-latest` or `ubuntu-24.04` to `starsling-ubuntu-24.04`.

## How is StarSling different from fast runner providers?

Fast runner providers primarily make jobs run faster on better infrastructure. StarSling combines fast runners with agents that continuously improve the CI pipeline itself.

## What runner label does StarSling use?

`starsling-ubuntu-24.04`, a drop-in replacement for `ubuntu-latest` and `ubuntu-24.04`.

## How much does StarSling cost?

New accounts get 2,000 free minutes the first month, then $0.008/min for 4 vCPU / 16 GB Linux runners (33% cheaper than GitHub Actions' $0.012/min). Queue time is never billed and there are no seat fees.

## What does StarSling optimize?

Caching, dependency installs, build parallelization, test sharding, and workflow structure. Agents open pull requests that engineers review and merge.
