Hi HN, I'm Chester.

  Not actually a programming language — it's a workflow runner                                                                                                                  
  with 412 built-in modules.                                                                                                                                                    

    name: price-monitor
    steps:
      - module: browser.goto
        params: { url: "https://competitor.com/pricing" }
      - module: browser.extract
        params: { selector: ".price-card" }
      - module: api.slack.send
        params: { channel: "#pricing", text: "${extract.data}" }

    $ pip install flyto-core && flyto run monitor.yaml

  Modules cover browser (38), Docker (6), K8s (5), SSH (3),
  S3 (4), image (9), crypto (4), 78 categories total.

  Every run gets an execution trace and state snapshots.
  If step 3 fails, replay from step 3 — no re-run.

  Also usable as Python library, HTTP API, or MCP server.
