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.
Browser Use's hosted-agent offering and standalone browser infrastructure are separate options. Keep the comparison at the browser layer when your application already owns its controller; compare execution ownership separately if the hosted agent is part of the requirement.
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 | Browser Use | Notte |
|---|---|---|
| Saved browser state | Documented | Documented |
| Credential handling | V4 secret bindings | Documented |
| Website sign-in | Profile / 2FA flows | Documented |

Website login
Browser Use: V4 secret bindings give credentials aliases and allowed hostnames for use in a run. Profiles reuse existing state; the separate 2FA guide addresses verification during authenticated work.
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
Browser Use: Profiles persist cookies, local storage and login state between browsers. Browser settings select a profile for a run. A session's conversation history and a profile's browser state are different resources.
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
Browser Use: Browser time and hosted-agent/model usage are separate pricing questions. Select the infrastructure path before comparing rates, and account for retained idle browser time and network usage where applicable.
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 Browser Use-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.
Browser Use: A hosted-agent run is a different execution unit from your deployed browser script. Keep comparisons focused on the browser path when measuring session speed and price.
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.
