Sylphx RunnersPreview

GitHub Actions runners: one clean machine per job.

Part of Sylphx: the same account, the same key, and the same bill as every other service. In the same league as Blacksmith, Depot.

What Sylphx Runners does

  • Drop-in runners

    Change runs-on to a sylphx-linux-<size> class. Install the Sylphx Runners GitHub App once per organization.

  • One job, one machine

    Each runner gets its own machine for exactly one job, then the machine is wiped.

  • No lost jobs

    Missed webhooks are filled from GitHub’s delivery log, so a queued job always gets a runner.

  • Billed per runner minute, by size.

Quickstart

Your first call

Install the SDK, set SYLPHX_API_KEY to a key from the console, and call the API. The CLI speaks the same API.

index.ts
import { Sylphx } from '@sylphx/sdk'

// Reads SYLPHX_API_KEY: one key for every Sylphx service.
const sylphx = new Sylphx()
const me = await sylphx.access.whoami({})

for await (const item of sylphx.runners.scaleSets.listAll({ parent: me.org! })) {
  console.log(item.name)
}
Install
npm install @sylphx/sdk
CLI
sylphx runners scale-sets list
