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.
Browserbase's TypeScript Function contract is a reason to retain it when that is the deployed language your team wants. A move to Notte Functions includes a Python execution decision; moving only the browser can leave your existing controller in place.
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 | Browserbase | Notte |

| Saved browser state | Contexts | Documented |
| Credential handling | Identity / Secrets | Documented |
| Website sign-in | Website auth tools | Documented |

What survives a session
Browserbase: Contexts preserve browser data between sessions. Associate the intended Context with each user's browser and decide which sessions may update it; a Context is distinct from a live running session.
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
Browserbase: The identity documentation covers website authentication and reuse of login state. Contexts and Function Secrets serve different roles: retained browser state versus values available to executing code.
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
Browserbase: Compare the public plan's included browser allowance and overage with the workflow's duration. Include proxy traffic and any separately priced services; an Arena browser-hour estimate does not describe the whole Browserbase bill.
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 Browserbase-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.
Browserbase: An identity feature, a persisted Context and a Function secret solve different problems. Select the required combination instead of treating all three as automatic login.
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.
