Decide whether this move earns its cost
A team releases a browser automation change, discovers a regression and needs to restore a known implementation while retaining the history of affected runs.
Anchor's demonstration or prompt-authored Automation Tasks and Notte's Python Functions suit different authoring preferences. Both document website-authentication tooling, so a credible recommendation must address the actual login and workflow-editing path.
Notte's Python deployment and run-history layer is relevant when release management belongs with browser execution. Its documented rollback approach redeploys an earlier implementation as the latest version.
Retain another execution platform when its language, dependency packaging or version-selection contract is essential to the application. Similar version numbers do not establish the same invocation semantics.
Keep the result contract stable
Two harmless code versions that return different markers and a recorded invocation for each version.
New runs execute the intended implementation after rollback, while historical runs remain associated with the implementation that actually ran.
Preserve the evidence contract across the move: Deployed implementation marker, invocation configuration, historical run version and rollback result.
Map the workflow's resources
| Requirement | Anchor Browser | Notte |
|---|---|---|
| Code execution | Automation Tasks | Python Functions |
| Scheduled execution | Task execution path | Native |
| Recordings / replay | Documented | Documented |

Deployment ownership
Anchor Browser: Use a browser session from existing code or deploy a reusable Automation Task. The task path includes workflow editing and versioning; direct CDP leaves execution ownership with your application.
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.
Where the code runs
Anchor Browser: Automation Tasks produce versioned workflows from a prompt or a recorded demonstration. Test and edit the workflow, then invoke it through the task API. Compare this authoring model with writing a handler directly.
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.
Pricing model
Anchor Browser: Compare the selected browser and task offering using Anchor's current commercial terms. Include network usage and the execution path actually used; a batch API's capacity is not a price quote for that batch.
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 Anchor Browser-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.
- Save the source implementation and the version behavior callers rely on.
- Deploy two target implementations with visible markers and record which one runs.
- Rehearse restoring the earlier implementation before routing production invocations.

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 | Two harmless code versions that return different markers and a recorded invocation for each version. |
| Pass condition | New runs execute the intended implementation after rollback, while historical runs remain associated with the implementation that actually ran. |
| Negative case | Invoke after changing the latest deployment and check whether the caller runs a pinned or latest version. The application must not infer the executed version from a filename. |
| Evidence to retain | Deployed implementation marker, invocation configuration, historical run version and rollback result. |
A reason to delay or keep the source
Invoke after changing the latest deployment and check whether the caller runs a pinned or latest version. The application must not infer the executed version from a filename.
Anchor Browser: A demonstrated automation task and an arbitrary Python handler are different authoring models. Evaluate how much control you need over the code, dependencies and exact workflow.
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.
