Code in an app's backend can now call the whole SDK and message your agents, signed in as its deployment, with no key to keep. It reads and writes only what it made itself, never another app's resources. Each app has a monthly budget, budget_usd_per_month ($10 unless you set another): once it's used, the app keeps serving pages and reading its data, while its paid calls fail with noclick.SpendCapExceeded.

Deployment.check loads pages of a deployment in a browser and reports each one's status, load time, console errors and a screenshot. Give an app check_paths and a promote is checked where it serves before production switches: a failed check leaves production as it was. Every promote bookmarks the app's databases first, so undoing it restores them too.

checked = preview.check(["/", "/book"]).wait()
for page in checked.paths:
    print(page.path, page.status, page.problem)

An app whose preview_resources is branch gives each preview branch its own copy of the databases, buckets, dicts and queues its code names, made at the branch's first write. Until then its reads reach production, read-only, so a branch that only reads makes nothing. Inside an app, Database.from_name finds the app's own database for the environment it runs in.

app.sign_in commits sign-in code into an app's repo, with its users in the app's own database. Google, Apple and Microsoft now sign people in through NoClick, so they work as soon as the operation ends, with no client to register at the provider. GitHub still uses your own client.

app = noclick.Project.from_name("booking")
setup = app.sign_in.enable(providers=["email", "google", "apple"]).wait()
print(setup.managed_providers)   # ['google', 'apple']

Repo.commits lists a branch's history, newest first, and each commit's page in Resources shows its changes, file by file.
