Decide whether this move earns its cost
A signed-in job requests a report from a website and transfers the completed file to application storage. A download beginning is not the delivery outcome.
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 belongs on the shortlist when saved account state and an executable browser workflow simplify the report job. Confirm the chosen file-transfer API and storage boundary in the current docs before moving the delivery step.
A working download-to-storage pipeline is a reason to retain the current provider until an equivalent artifact path is demonstrated. Neither a replay nor a successful page navigation proves that a file arrived.
Keep the result contract stable
A controlled report with a known filename, expected content marker and application-owned destination.
The application receives the complete expected file, verifies its content marker and associates it with the originating account and job.
Preserve the evidence contract across the move: Website report ID, file byte count, content verification and destination object reference.

Where the code runs
Browserbase: A Function is TypeScript code published with an entry point. Invocation starts asynchronously, creates a browser, passes its connection URL to the handler, and stores the result, logs and session ID. Function webhooks report status changes.
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
Browserbase: Publish TypeScript Functions through the supported deployment flow. The reviewed Function overview lists us-west-2 availability; this is narrower than assuming every browser region also hosts Functions.
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
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.
- Separate website report generation from provider file retrieval in the current code.
- Keep the destination and content check unchanged while replacing the retrieval path.
- Test delayed and interrupted downloads before switching scheduled report delivery.

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 controlled report with a known filename, expected content marker and application-owned destination. |
| Pass condition | The application receives the complete expected file, verifies its content marker and associates it with the originating account and job. |
| Negative case | Close the browser before a deliberately delayed download completes. The job must detect the missing or partial artifact instead of reporting a delivered report. |
| Evidence to retain | Website report ID, file byte count, content verification and destination object reference. |
A reason to delay or keep the source
Close the browser before a deliberately delayed download completes. The job must detect the missing or partial artifact instead of reporting a delivered report.
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.
