They run on Bilt Cloud, not on the user's phone, so secrets and sensitive logic never ship inside your app. There's no deploy button: **ask Bilt in chat** and it writes, deploys, and wires up the automation. You monitor everything on the **Automations** tab under **Settings → Database**. ## What you see Each automation shows its name, who may call it, when it was last deployed, and its status. Open one to see: * **Source** — the actual deployed code, so you can read exactly what runs * **Invocations** — every run with status, duration, timestamps, log lines, and full error details when something fails ## Who can call it Each automation is either: * **Sign-in required** — only signed-in users of your app can call it (the default to keep) * **Open to anyone** — anyone with the URL can call it. Use this only for webhooks (Stripe, GitHub) and public APIs. Open automations are rate-limited to 60 calls per minute per caller, versus 600 for signed-in users You can flip this per automation with **Make public** / **Require JWT** — Bilt warns you about the trade-offs before switching. ## Deleting Deleting an automation stops it immediately, but it stays **restorable for 1 hour** — ask Bilt to redeploy it under the same name to bring it back. After the hour, it and its logs are gone for good. ## Good to know * Secrets (API keys and the like) live on the server and are available to your automations — they're never bundled into the app. Bilt manages them for you when you ask for a feature that needs one * An automation can span multiple files, up to 1 MB of code * There's no built-in scheduler yet — for a recurring job, use an external scheduler that calls a public automation's URL on your cadence ## Ask for it in chat ```text theme={null} When a user submits an order, validate it on the server and save it to the database. ``` ```text theme={null} Send a welcome email when someone creates an account. ``` Email [support@bilt.me](mailto:support@bilt.me), or ask in the [Discord community](https://discord.gg/9Y8vpDAhbD).
