Can the provider start and run the fleet you need?
Concurrent sessions, session creation rate and HTTP request rate are different limits. A plan that allows a hundred open browsers may still need time to start them. Polling or retrying without a budget can exhaust API capacity before the browser cap is reached.
If a thousand jobs arrive together but only fifty browser slots are available, queue jobs before allocating browsers. Starting all jobs immediately can turn ordinary capacity management into timeouts, retries and idle browser charges.
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.
Compare the browser lifecycle
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.
AWS AgentCore Browser: Create or select a Browser Tool, then start an isolated browser session. The documented default session timeout is 15 minutes and the maximum is eight hours. Browser automation uses the session's WebSocket endpoints.
Compare the billing contract
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.
AWS AgentCore Browser: A complete AWS workflow may include browser use, the controlling compute service, storage and other metered services. Price the selected architecture and region instead of treating a browser benchmark rate as the final invoice.

How to evaluate this choice
A quota table establishes what an account may request. A measured concurrency curve establishes how the tested workload behaved. Keep both in the decision and avoid extrapolating a single-session result to a large fleet.
- Specify the number of simultaneously open browsers and the burst arrival rate.
- Measure time until every requested browser is ready for work.
- Record rate limits and honor the returned retry delay.
- Cap worker concurrency and keep queued tasks outside browser sessions.
- Include failed starts and cleanup in the load test's result.
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.
