Which parts of the browser stack will your team operate?
Managed browser access removes one infrastructure responsibility. Your team may still own the code runner, state store, scheduler and artifacts. A self-hosted engine moves more of that responsibility back into your environment.
Moving a browser to another region while leaving the controller in place changes the network path of every action. The advertised browser creation time does not describe those repeated round trips.
Compare 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.
Browser Use: Use the hosted browser from your own process or send a task to the hosted agent. The open-source local framework is another deployment option and should not be equated with the cloud subscription.
Compare the execution model
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.
Browser Use: The cloud offers hosted-agent runs and separately created browsers. The reviewed browser documentation does not establish a deploy-your-own Python Function equivalent. Keep an external script runner separate from a hosted agent when comparing execution ownership.
Compare operational limits
Notte: The public plans list 5, 25 and 100 concurrent browser sessions, with custom limits on Enterprise. Session duration and concurrent capacity are separate plan limits; a larger technical API limit does not override the plan.
Browser Use: The concurrency guide distinguishes concurrent browser capacity from the HTTP request budget. Keys in a project share capacity and credits. Polling frequency can exhaust request capacity even when there are free browser slots.
How to evaluate this choice
Use the deployment that fits the work your team wants to own. Reusing an existing runner can be practical; a hosted Function can reduce operations; self-hosting can meet a specific infrastructure requirement at the cost of operating it.
- Draw the controller, browser, state store and scheduler as separate components.
- Check the available browser and execution regions independently.
- Identify which provider owns upgrades, capacity and recordings.
- Verify code and stored-state portability before changing providers.
- Include maintenance and on-call work in a self-hosting decision.
Requirements side by side
| Requirement | Notte | Browser Use |
|---|---|---|
| Browser control | Documented | Documented |
| Saved browser state | Documented | Documented |
| Code execution | Python Functions | External worker or hosted agent |
| Deployment choice | Enterprise options | Local framework available |

Which approach fits?
Choose Notte when your browser workflow needs saved logins, credential fill or scheduled Python code alongside the browser.
Notte tradeoff: A saved profile restores browser state; it does not prove that a website still considers the user signed in. Use Managed Auth when the workflow needs connection readiness before it starts.
Choose Browser Use when you use Browser Use's framework or want its hosted browsers while retaining the option of a hosted browser agent.
Browser Use tradeoff: A hosted-agent run is a different execution unit from your deployed browser script. Keep comparisons focused on the browser path when measuring session speed and price.
A useful acceptance check
Write a pass/fail result for the real task before running the evaluation. Record the account, configuration and code version next to that result. Repeat failures need an explanation, not an automatically different browser configuration.
