Decide whether this move earns its cost
A customer authorizes an application to operate an existing website account. The application must distinguish a usable connection from a browser that merely started.
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 Managed Auth is relevant when a saved website connection and its readiness check should precede browser execution. A profile and a credential vault remain distinct resources.
Another provider's managed-auth flow can be the better fit when it already supports the application's consent and handoff experience. Confirm supported websites and the actual user path rather than comparing the feature name.
Keep the result contract stable
A consenting test user, the intended website account and an application-owned connection mapping.
The task waits for a usable connection and verifies the expected account before taking an action on the customer's behalf.
Preserve the evidence contract across the move: Consenting application user, intended account, connection reference and readiness outcome.
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 |

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.
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.
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.
- Inventory the source connection's owner and the actions the user authorized.
- Create a target connection through an authorized user flow instead of copying provider-owned IDs.
- Verify readiness, account identity and the user handoff before moving customer tasks.

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 | A consenting test user, the intended website account and an application-owned connection mapping. |
| Pass condition | The task waits for a usable connection and verifies the expected account before taking an action on the customer's behalf. |
| Negative case | Start a test with a connection that is not ready. The browser workflow must stop or request the required user step rather than acting in an anonymous or different account. |
| Evidence to retain | Consenting application user, intended account, connection reference and readiness outcome. |
A reason to delay or keep the source
Start a test with a connection that is not ready. The browser workflow must stop or request the required user step rather than acting in an anonymous or different account.
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.
