Browserbase vs Steel for browser infrastructure.

Browserbase and Steel overlap substantially. Both provide remote browser sessions. Both support common automation libraries. Both also provide managed cloud plans.

The important difference starts with ownership. Browserbase centers its managed cloud. Steel publishes an Apache-licensed browser runtime. Teams can run that runtime themselves.

Self-hosting creates freedom and responsibility. Your team owns capacity and maintenance. Managed cloud removes much of that work. It also keeps infrastructure decisions vendor-managed.

Start with that operational preference. Then compare geography, concurrency, and session length. Finally compare observation and saved state. Pricing comes after workload definition.

Both vendors cover mainstream browser control. Browserbase documents Playwright, Puppeteer, and Selenium. Steel documents those same three integrations. Existing library choice rarely settles this decision.

State handling also overlaps. Browserbase contexts preserve cookies and browser state. Steel profiles preserve reusable session state. Implementation details still differ between those systems.

Observation exists on both platforms. Browserbase provides live view and Session Inspector. It also records session video automatically. Steel provides WebRTC live view and recordings.

The table highlights operating consequences. It avoids assigning universal winners. A required capability only matters when used. Unused breadth should not justify migration.

The vendors package usage differently. Browserbase plans include browser hours. Paid plans then charge hourly overages. Included proxy traffic also varies by plan.

Steel charges subscriptions plus measured usage. Its paid Scale plan includes monthly credits. Launch includes one-time credits with expiration. Session caps also vary by plan.

Headline prices therefore mislead easily. Model the same monthly browser hours. Add the same transferred proxy traffic. Apply the required concurrency level.

Do not ignore engineering ownership. Self-hosting replaces vendor fees with internal work. That work includes updates and capacity. It also includes incident response.

Deployment is not a binary checkbox. Control increases through several practical levels. Each level transfers more operational ownership. Procurement should name the required level.

Browserbase offers shared managed cloud. Enterprise discussions can include private cloud options. Steel offers managed cloud and local deployment. Its source code supports deeper self-management.

Local Steel is not Cloud locally. Official documentation names meaningful capability gaps. Local concurrency is limited to one. Managed routing requires customer infrastructure.

A self-managed runtime still needs supporting systems. Teams need monitoring and capacity controls. They also need secure release practices. Source availability does not supply operations.

Browser sessions fail in visible ways. Operators need the page state. Developers need events and timelines. Support teams often need recordings.

Browserbase Session Inspector exposes session activity. Live view supports active observation. Automatic video preserves a replay artifact. Contexts carry state across separate sessions.

Steel provides WebRTC live viewing. Cloud recordings are available as MP4 or HLS. Agent Traces record agent-specific browser activity. Profiles provide reusable browser state.

Similar labels can hide workflow differences. Test sharing, access, retention, and export. Test profile creation and update behavior. Avoid assuming identical state semantics.

Concurrency alone does not define capacity. Session duration can become the bottleneck. Routing geography can become another bottleneck. Local feature gaps can change architecture.

Browserbase documents sessions reaching 6 hours. Actual availability depends on plan settings. Its managed routing covers 201 countries. Those facts suit distributed workloads.

Steel Launch sessions cap at 15 minutes. Scale sessions cap at 1 hour. Enterprise sessions can reach 24 hours. Steel Cloud starts new sessions headful.

Steel Local permits one concurrent session. It lacks full Cloud feature parity. Customer supplied routing remains the local path. Evaluate local and Cloud separately.

Browserbase fits teams preferring managed infrastructure. Its location breadth supports geographically varied tasks. Contexts support recurring stateful workflows. Inspector tooling supports cloud operations.

Steel fits teams prioritizing runtime ownership. Open source supports direct inspection and modification. Steel Cloud still offers managed convenience. Agent Traces add focused diagnostic evidence.

Neither product wins every procurement. Existing skills and operating models matter. Geographic requirements can settle the choice. Self-hosting mandates can settle it faster.

Write the decision before running demonstrations. State the mandatory operating model. State the required session shape. Then test only unresolved questions.

Some evaluations begin with excess platform surface. The real requirement is smaller. An agent needs routing and browser isolation. Each task needs its own session.

Legba packages that requirement as a skill. It runs browser sessions on Legba infrastructure. It does not claim Browserbase compatibility. It does not claim Steel compatibility.

That boundary should remain explicit. Legba is not the self-hosting choice. It is not the broad browser-cloud choice. It is the focused agent-skill choice.

Review the agent-skill overview first. Then inspect current developer documentation. Test one complete task before switching. Keep required platform features where needed.
