Decide whether this move earns its cost
A recurring job signs in, performs a permitted browser task and records its result without an interactive caller. Overlapping triggers must not create unintended duplicate work.
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 is a natural candidate when a scheduled Python handler and its browser should share an execution platform. Check schedule behavior and browser duration independently.
Keep an existing scheduler or a provider-native execution language when it already meets the job contract and a Python port would add unnecessary maintenance. A triggered request is not proof of completion.
Keep the result contract stable
A test schedule with an explicit timezone, fixed inputs and a destination that exposes whether the operation ran once.
Each scheduled attempt has a terminal execution record and a verified business result, and the expected browser cleanup occurs.
Preserve the evidence contract across the move: Scheduled time and timezone, execution ID, business result and overlap outcome.

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.
- Pause the target schedule while replaying a fixed input manually.
- Verify the Python handler's result and browser cleanup before enabling a canary schedule.
- Run only one authoritative production schedule during cutover and preserve source run history.

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 test schedule with an explicit timezone, fixed inputs and a destination that exposes whether the operation ran once. |
| Pass condition | Each scheduled attempt has a terminal execution record and a verified business result, and the expected browser cleanup occurs. |
| Negative case | Let one test run outlive the next trigger. Inspect the overlap policy and verify the intended number of website changes. |
| Evidence to retain | Scheduled time and timezone, execution ID, business result and overlap outcome. |
A reason to delay or keep the source
Let one test run outlive the next trigger. Inspect the overlap policy and verify the intended number of website changes.
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.
