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
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.
Compare the execution model
Browserbase: A Function is TypeScript code published with an entry point. Invocation starts asynchronously, creates a browser, passes its connection URL to the handler, and stores the result, logs and session ID. Function webhooks report status changes.
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.
Compare operational limits
Browserbase: Browser and Function constraints have separate documentation. Check the account's concurrent browser limit, the Function runtime cap and the Function region rather than assuming a browser entitlement covers every execution path.
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.
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.

Which approach fits?
Choose Browserbase when you want to deploy TypeScript browser logic or already use Browserbase's browser and Stagehand tooling.
Browserbase tradeoff: An identity feature, a persisted Context and a Function secret solve different problems. Select the required combination instead of treating all three as automatic login.
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
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.
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: 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.
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.
