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.
Hyperbrowser's profiles, credential tools and Action Caching deserve separate evaluation. A recorded action sequence and a deployed Python handler have different maintenance contracts, so decide which one your team will edit after the website changes.
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.

Where the code runs
Hyperbrowser: Action Caching records a HyperAgent action sequence for deterministic replay. The broader platform also offers sandbox compute. Check how a handler is deployed, invoked and versioned before choosing the execution path.
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
Hyperbrowser: Control a Hyperbrowser session from your application using the supported SDK or CDP library. Treat sandbox hosting as an additional execution choice and check its own runtime and storage contract.
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
Hyperbrowser: The reviewed pricing page lists $0.10 per browser-hour and $10 per GB of proxy traffic. Credits acquired through subscriptions and direct purchases have different refresh or expiry behavior.
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 Hyperbrowser-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.
Hyperbrowser: Browser sessions, sandbox execution and action caching are separate surfaces. A cached action sequence is not the same deployment contract as an independently versioned browser Function.
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.
