The three-way buying decision
This shortlist starts with Browserbase and Tilion, then includes Notte as a third implementation path for regional browser deployment. A controller makes repeated browser calls across regions. The application needs to choose where the controller and browser run, not just where a proxy exits.
A proxy exit country is not the browser's hosting region. Every action can pay a round trip between the controller and browser, so record both locations.
A proposed acceptance case
A controller makes repeated browser calls across regions. The application needs to choose where the controller and browser run, not just where a proxy exits.
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 | The intended controller region, the configured browser region and a fixed sequence of page actions. |
| Pass condition | The chosen deployment meets the end-to-end action budget from the intended controller location, with browser and proxy locations recorded separately. |
| Negative case | Run the controller from a deliberately distant region. Detect the changed action latency instead of attributing every delay to browser creation. |
| Evidence to retain | Controller region, browser region, proxy configuration and per-action timing distribution. |
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.

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.
Tilion: The public access path currently points to a waitlist and contact. A production integration needs an agreed API contract, service access and ownership of the browser lifecycle.
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.

Browser control
Browserbase: Create a managed browser session and connect a supported browser library to its connection URL. The session API and the browser connection have separate lifecycles.
Tilion: BrowserArena includes a Tilion session integration. The reviewed public Tilion homepage does not publish the full session API contract; obtain the supported connection and lifecycle instructions through its access flow.
Notte: Create an owned browser session, connect Playwright or Puppeteer over CDP, and stop the session when the work finishes. Browser lifecycle management remains necessary even when the control socket disconnects.

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.
Tilion: Arena provides an estimated usage rate for its test. The reviewed public homepage does not establish a self-serve production plan, allowances or overage terms. Obtain those terms before quoting a monthly 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.

What should change the choice?
Notte is a candidate when its available deployment path fits the application region and operational requirements. Use the controller-to-browser path in the pilot rather than inferring placement from Arena's median.
Browserbase: 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.
Tilion: The reviewed Tilion homepage offers a waitlist and contact route. Arena's tested integration is useful evidence about a run, but a purchasing or migration decision still needs a documented access, state and execution contract; those unknowns must remain visible beside Notte's public docs.
Keep a provider's browser-local code path or established regional deployment when it materially reduces repeated calls. A lower browser-hour rate does not remove network round trips.

How to remove an option from the shortlist
For this workflow, require the following evidence from Browserbase, Tilion and Notte: Controller region, browser region, proxy configuration and per-action timing distribution.
Remove a proposed configuration when its documented mechanism or a controlled pilot cannot meet the pass condition. Keep an undocumented feature as an unresolved question instead of inventing an equivalence. Do not select a provider solely because it appears in this shortlist.
- The chosen deployment meets the end-to-end action budget from the intended controller location, with browser and proxy locations recorded separately.
- Run the controller from a deliberately distant region. Detect the changed action latency instead of attributing every delay to browser creation.

Make a bounded pilot
Measure a fixed action sequence from the intended application region and keep browser and proxy configuration consistent across providers.
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.
- Record source controller, browser and proxy locations separately.
- Run the same controller action sequence against the target from the real application region.
- Move only after both action latency and the deployment responsibilities fit the budget.
