The workflow decision
For reconnecting to browser work, the useful comparison is whether Notte or Cloudflare Browser Run can meet the following outcome: The application determines whether the original browser is still alive and either resumes the expected state or explicitly restarts the task.
Disconnecting a control socket, stopping a browser and restoring a saved profile are separate operations. A new connection may resume a live page or start a fresh browser, depending on the product.
A proposed acceptance case
A controller loses its connection midway through a safe task and attempts to continue. Starting a fresh browser is not always equivalent to reconnecting to a live page.
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 page with unsaved in-memory state, a stored provider session reference and a controlled controller interruption. |
| Pass condition | The application determines whether the original browser is still alive and either resumes the expected state or explicitly restarts the task. |
| Negative case | Repeat the reconnect after the browser has ended. The application must not treat a new session or restored profile as the original live page. |
| Evidence to retain | Original session reference, page-state marker, connection interruption and resume-or-restart decision. |
Documented mechanisms, side by side
These labels describe product mechanisms. The linked source and the acceptance case determine whether a mechanism meets this workflow's requirement.
| Requirement | Notte | Cloudflare Browser Run |
|---|---|---|
| Browser control | Documented | Documented |
| Saved browser state | Documented | Session reuse / custom state |
| Live view | Documented | Beta |
| Deployment choice | Enterprise options | Cloudflare service |

What survives a session
Notte: Profiles save cookies, local storage and session storage. Sessions start with fresh state by default. Persisting a profile writes state back when the session ends; a running session can also save its state explicitly.
Cloudflare Browser Run: Cloudflare documents reuse of browser sessions and a Durable Objects integration. Keeping a session alive is different from exporting a portable authenticated profile; design the required state store explicitly.
Website login
Notte: Vaults substitute credential placeholders in supported browser actions outside the model context. Managed Auth checks requested saved connections before automation. Personas supply an inbox and optional phone number for verification workflows.
Cloudflare Browser Run: Use browser code to implement the website's sign-in flow and retain the necessary session state. The reviewed overview does not establish a managed website connection that checks sign-in readiness before a workflow starts.
Deployment ownership
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.
Cloudflare Browser Run: A Worker-based deployment fits Cloudflare application infrastructure; direct CDP keeps the controller elsewhere. Durable Objects are a composition for stateful browser work rather than a generic persistent browser profile.
Pricing model
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.
Cloudflare Browser Run: Price browser usage and the Worker execution components required by the workload. The Browser Run pricing page, rather than a single browser-hour estimate, defines included allowances and applicable limits.
What should change the choice?
Evaluate Notte when browser ownership can be tracked independently of a transient controller socket. Confirm the supported reconnection path and distinguish it from loading a saved profile.
Cloudflare Browser Run: Cloudflare can be an economical architectural choice when Workers and the surrounding scheduling already exist in your application. Notte is worth evaluating when a browser, deployed Python handler and authentication workflow should share a product rather than a Workers composition.
A provider's documented reconnect product can be decisive for a workflow that depends on a live page. Do not replace it with profile persistence without changing the task's continuation design.

The cost boundary
Use the same attempted work and eligible account capacity in both estimates. The browser-hour rate does not include every proxy, execution or identity meter, and the cost of an incomplete job is still part of the workflow budget.
The workload evidence should include: Original session reference, page-state marker, connection interruption and resume-or-restart decision.
Make a bounded pilot
Interrupt the controller connection during a safe task, reconnect through the documented path, and inspect the page and account state before continuing.
Use the same authorized account, input and final-state check in each configuration. Treat a missing product contract as an open question; do not turn an undocumented capability into an unsupported claim or a successful test result.
- Inventory which steps depend on unsaved page state.
- Test the target session's documented connection path before moving continuation logic.
- Retain a restart path for ended sessions and verify that cleanup still occurs.
