Scheduled JavaScript.
Zero infrastructure.

GearTrain runs your JavaScript on a schedule: a built-in editor, a persistent file system, a sandboxed runtime, cron scheduling, secrets, and full run history.

A sandboxed runtime.

Scripts use the Web APIs you already know from the browser, plus built-in modules. No packages to install, nothing to set up. 

import fs from "fs";
const res = await fetch("https://api.example.com/data");
await fs.writeFile("/data/latest.json", await res.text());

You shouldn't need a server to run a script.

To run a script on a schedule today you need: a server, a JS runtime installed and maintained, a file system to manage, a way to deploy, a separate code editor, and something to tell you when it fails.

GearTrain removes all of that.

How it works

1

Write

Write scripts in the built-in editor; no local setup.

2

Schedule

Set a cron expression, or start a run manually.

3

Relax

Runs execute in a sandbox; watch the console live and come back to the full history.

Everything it takes to run a scheduled script

Built-in editor

Write and edit scripts without a separate tool.

Built-in file system

A persistent file system for scripts, data, and anything else; files survive between runs.

Sandboxed runtime

Isolated execution with web-standard APIs.

Manual runs

Start a run manually and watch the console live, with per-run environment variables for one-off values.

Secrets

Store credentials encrypted, then read them in scripts as environment variables.

Run history

Every run recorded with status, duration, and console output.

Small by design.

GearTrain offers a curated set of web-standard APIs (fetch, timers, streams, URL, and more) plus a file system. Everything a scheduled script needs, already built in.
