Browserbase vs Steel

Both are relevant to the browser-runtime decision. Steel’s open-source browser API creates an additional deployment question; Browserbase presents a broader managed platform.

Shared layer; different tradeoffs.

Meaningful differences

Steel documents an open-source browser API as well as managed cloud browsers; this creates a self-operated versus managed evaluation branch.
Browserbase documents browser sessions plus a wider platform including agent, search, fetch, and execution services.
A self-operated runtime shifts patching, capacity, network policy, and incident response to your team; compare that responsibility with the managed offering actually being purchased.
Keep the same controller and tasks while testing runtime options. Provider-reported reachability results do not prove your agent’s end-to-end task success.

Fit by workflow

Existing Playwright worker

Test connection, downloads, session cleanup, and concurrent-job isolation.

Private deployment evaluation

Establish which features are in the self-operated package and which require a managed service.
