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.
AWS AgentCore Browser: Use an AWS-managed Browser Tool or configure a custom browser with recording, networking and an execution role. Keep the controller's deployment separate in the architecture and operational estimate.
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.
AWS AgentCore Browser: The Browser Tool supplies the browser environment. An external process or another AWS execution service runs the application code that controls it. Identify that service and its runtime before comparing it with a deployed browser Function.
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.
AWS AgentCore Browser: AgentCore Browser supports multiple simultaneous sessions. Review AWS quotas and the chosen tool/session configuration; the browser session's timeout and the controller's execution timeout are separate limits.
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 | AWS AgentCore Browser |
|---|---|---|
| Browser control | Documented | Browser automation endpoint |
| Saved browser state | Documented | Explicit state design |
| Code execution | Python Functions | External AWS compute |
| Deployment choice | Enterprise options | AWS service |

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 AWS AgentCore Browser when your application already uses AWS identity, logging and storage, and browser workflows need to fit those systems.
AWS AgentCore Browser tradeoff: The browser tool is not the entire AgentCore platform. Do not assign capabilities from unrelated AgentCore execution or identity products to a browser session without specifying the composition.
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.
