Move scheduled browser Functions from Browserless to Notte

A migration plan for scheduled browser Functions: retain the business check, replace Browserless's provider-owned resources, and prove the Notte workflow before cutover.

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.

Choose the Browserless product and deployment before drawing a conclusion from its documentation. BAP, shared browser access and a self-hosted service can have different features; Notte's session and Function resources should be compared with the specific path you would purchase.

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

Browserless: Browserless supports several code and control surfaces. Compare the exact runtime endpoint or external runner you intend to use, including its language, deployment, versioning and invocation contract.

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

Browserless: Browserless has cloud and self-hosted deployment paths. Managed dedicated deployments expose some account APIs that a fully self-hosted installation does not, so document the actual deployment rather than a generic feature list.

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

Browserless: Browserless Cloud uses units. Browser time consumes one unit per 30-second increment, rounding partial increments upward; proxy traffic and other services also consume units. Included units and overage depend on the plan.

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 Browserless-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 testRequired observation
Controlled inputA test schedule with an explicit timezone, fixed inputs and a destination that exposes whether the operation ran once.
Pass conditionEach scheduled attempt has a terminal execution record and a verified business result, and the expected browser cleanup occurs.
Negative caseLet one test run outlive the next trigger. Inspect the overlap policy and verify the intended number of website changes.
Evidence to retainScheduled 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.

Browserless: The connection route and product matter. A feature documented for BAP or a managed dedicated deployment should not be assumed to exist on every shared BaaS endpoint.

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.
