What will the same completed work cost?
Start with the work that has to finish: executions per month, browser time per execution, concurrent browsers and network traffic. Choose the cheapest eligible plan for that workload. An hourly rate can be lower while the bill is higher because a plan floor, billing minimum or extra service applies.
For 10,000 runs lasting three minutes, browser time is 500 hours before rounding, setup and retries. At Notte's published $0.01 browser-hour rate, that meter is $5. Paid-plan eligibility and any proxy or Function usage still determine the total bill.
Compare the billing contract
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.
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.

Compare operational limits
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.
Tilion: Arena's observed test concurrency is a test configuration, not an account entitlement. Obtain the production concurrency and session creation limits for your access tier before sizing a fleet.
Compare the execution model
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.
Tilion: Public documentation reviewed for this comparison does not establish a deployable Function or app-action contract. Confirm where your automation code runs and how invocation, versioning and logs work before choosing the execution path.
How to evaluate this choice
A useful cost comparison gives both a usage estimate and the eligible monthly plan. Keep an unsupported workload out of the price ranking even if a rate can be multiplied into an attractive number.
- Count attempted runs as well as successful runs.
- Apply the provider's rounding rule to each session before adding usage.
- Separate browser time, function compute, proxy traffic and identity services.
- Apply included credits once; do not add the same subscription fee again.
- Mark an ineligible plan as a capacity mismatch rather than a cheap option.
Requirements side by side
| Requirement | AWS AgentCore Browser | Tilion |
|---|---|---|
| Browser control | Browser automation endpoint | Arena integration |
| Saved browser state | Explicit state design | Not established |
| Code execution | External AWS compute | Not established |
| Deployment choice | AWS service | Not established |
Which approach fits?
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.
Choose Tilion when you can obtain access and test the product directly, with its current API and commercial terms in hand.
Tilion tradeoff: Arena measurements do not establish public availability or feature completeness. Confirm access, API details and plan terms before planning a production migration.
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.
When Notte belongs on this shortlist
AgentCore Browser's AWS integration can matter more than moving a browser endpoint. Retain AWS identity and observability requirements in the evaluation, and separately account for the code runner and website login before comparing Notte's integrated workflow.
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.
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.
Consider this third option when its documented mechanism addresses a requirement left open by the two providers above. A working configuration on either original provider can still be the better choice; compare the task and ownership cost before switching.
