Decide whether this move earns its cost
A recurring job returns to the same website account in a later browser session. A stored profile must restore the intended user without assuming the website login is still valid.
Cloudflare can be an economical architectural choice when Workers and the surrounding scheduling already exist in your application. Notte is worth evaluating when a browser, deployed Python handler and authentication workflow should share a product rather than a Workers composition.
Notte profiles are relevant for restoring cookies and web storage. Add its managed connection flow when the requirement includes login readiness rather than state restoration alone.
Keep a source profile or context integration when its documented storage behavior is essential and already verified. State should move only through a supported export/import contract or a fresh authorized login.
Keep the result contract stable
An authorized account, its expected identity marker and two separately created browser sessions.
The second session reaches a protected page as the expected account after loading the target provider's saved-state resource.
Preserve the evidence contract across the move: Expected account, source and target state references, second-session identity and expired-login result.
Map the workflow's resources
| Requirement | Cloudflare Browser Run | Notte |
|---|---|---|
| Saved browser state | Session reuse / custom state | Documented |
| Credential handling | Application-owned | Documented |
| Website sign-in | Not established | Documented |

What survives a session
Cloudflare Browser Run: Cloudflare documents reuse of browser sessions and a Durable Objects integration. Keeping a session alive is different from exporting a portable authenticated profile; design the required state store explicitly.
Notte: Profiles save cookies, local storage and session storage. Sessions start with fresh state by default. Persisting a profile writes state back when the session ends; a running session can also save its state explicitly.
Website login
Cloudflare Browser Run: Use browser code to implement the website's sign-in flow and retain the necessary session state. The reviewed overview does not establish a managed website connection that checks sign-in readiness before a workflow starts.
Notte: Vaults substitute credential placeholders in supported browser actions outside the model context. Managed Auth checks requested saved connections before automation. Personas supply an inbox and optional phone number for verification workflows.
Pricing model
Cloudflare Browser Run: Price browser usage and the Worker execution components required by the workload. The Browser Run pricing page, rather than a single browser-hour estimate, defines included allowances and applicable limits.
Notte: The public usage rates are $0.01 per browser-hour, $0.05 per Function-hour and $10 per GB of managed proxy traffic. Paid plans return their price as usage credits. Price the relevant meters and plan eligibility for the workload.
Cut over one responsibility at a time
For this Cloudflare Browser Run-to-Notte migration, keep the business assertion outside provider resource management. Source profile, connection, file and execution IDs are not valid target IDs; use a documented transfer path or establish the corresponding resource in Notte.
Retain source job history and a rollback route until the target pilot passes. A migration checklist is not evidence that saved state or runtime behavior is automatically portable.
- Record the source account-to-profile mapping without treating its identifier as portable.
- Establish an authorized login in a target session and save it using the target profile contract.
- Verify the account in a second target session and in an expired-login test before changing recurring jobs.

A proposed acceptance case
This is an evaluation design, not a claim that this workflow has been executed successfully on every provider.
| Part of the test | Required observation |
|---|---|
| Controlled input | An authorized account, its expected identity marker and two separately created browser sessions. |
| Pass condition | The second session reaches a protected page as the expected account after loading the target provider's saved-state resource. |
| Negative case | Invalidate the test website login between sessions. The workflow must detect the expired account state before performing the task. |
| Evidence to retain | Expected account, source and target state references, second-session identity and expired-login result. |
A reason to delay or keep the source
Invalidate the test website login between sessions. The workflow must detect the expired account state before performing the task.
Cloudflare Browser Run: A Worker and a browser session have separate resource and lifecycle constraints. Confirm the chosen browser library and binding path instead of assuming an unchanged local browser script will deploy directly.
Delay cutover when the target's selected plan, required artifact path or supported website-account flow is not established. Resolve that gap before moving real jobs, even if the rate comparison favors the target.
