Decide whether this move earns its cost
A deployed handler performs browser work longer than the caller is willing to wait. The execution must have an observable outcome even after the request ends.
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 is worth evaluating when a Python handler's run history can replace ad hoc background-job tracking. Confirm the actual runtime and cancellation contract rather than borrowing browser session limits.
An existing worker or provider execution service may fit a long task better when its runtime and cancellation behavior are already proven. A successful browser connection is not a runtime entitlement.
Keep the result contract stable
A safe delayed handler, a short caller wait budget and a stored execution reference.
The application can determine the execution's terminal state and browser ownership after the caller stops waiting, then retrieve or cancel work through the documented path.
Preserve the evidence contract across the move: Caller timeout, execution reference, handler terminal state, cancellation result and browser release.
Map the workflow's resources
| Requirement | Browser Use | Notte |
|---|---|---|
| Code execution | External worker or hosted agent | Python Functions |
| Scheduled execution | Check execution setup | Native |
| Recordings / replay | Recording option | Documented |

Where the code runs
Browser Use: The cloud offers hosted-agent runs and separately created browsers. The reviewed browser documentation does not establish a deploy-your-own Python Function equivalent. Keep an external script runner separate from a hosted agent when comparing execution ownership.
Notte: Functions deploy Python code with a run() entry point. Invoke them over HTTP or with an SDK, inspect run history, and roll back code by redeploying an earlier version as the latest version.
Deployment ownership
Browser Use: Use the hosted browser from your own process or send a task to the hosted agent. The open-source local framework is another deployment option and should not be equated with the cloud subscription.
Notte: Use a remote browser from your existing process or deploy the browser automation as a Notte Function. These choices put lifecycle, scheduling and monitoring responsibilities in different places.
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.
- Record source caller, handler and browser timeouts as separate budgets.
- Port the handler without changing the business completion check.
- Prove post-timeout status lookup, cancellation and browser cleanup before moving long 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 | A safe delayed handler, a short caller wait budget and a stored execution reference. |
| Pass condition | The application can determine the execution's terminal state and browser ownership after the caller stops waiting, then retrieve or cancel work through the documented path. |
| Negative case | Interrupt the caller and request cancellation in a controlled test. Inspect both the handler outcome and whether its browser remains allocated. |
| Evidence to retain | Caller timeout, execution reference, handler terminal state, cancellation result and browser release. |
A reason to delay or keep the source
Interrupt the caller and request cancellation in a controlled test. Inspect both the handler outcome and whether its browser remains allocated.
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.
