Apps
What an account holder can do with an app — deploy it, configure it, observe it.
An app is a celld Worker with a git remote. The owner creates it in the UI; deploys follow every push to that remote.
Deploy
Push code over Git smart-HTTP or from CI. Each push builds, releases, and goes live behind http://<slug>.<domain>.
Configure
Env vars, custom domains, collaborators, source edits, and storage inspection — all from the app detail page.
Observe
Runtime logs, request metrics with spans, product-analytics events, and idle sleep behavior.
Deploy
Create an app, push with git, deploy from CI, and what each push triggers.
Configure
Env vars, custom domains, collaborator roles, web commits, and storage.
Observe
Logs, metrics and spans, events and insights, and scale-to-zero sleep.
App slugs are 1–48 chars: lowercase letters, digits, hyphens, starting and ending with a letter or digit. Reserved: _control, app, api, git.
