Managed vs self-hosted

Local Chromium in a VM can feel fast in the happy path. In production you inherit the full cost of operating a browser fleet: session lifecycle, pooling, memory leaks, crash recovery, concurrency, updates, observability, and security isolation. This page explains that tradeoff for teams using Skills and other Browserbase integrations, and what you take on when you self-host.

​

What you own when you DIY

When you run your own Chromium in VMs or containers, you own:

• Session lifecycle: Browsers leak memory; sessions hang. You need pooling, recycling, and sane timeouts.
• Concurrency: Parallel browser processes under load fail in ways that are hard to reproduce locally.
• Crash recovery: Silent failures at scale are dangerous; you need health checks, retries, and clear failure modes.
• Debuggability: Headless stacks and logs help; production debugging often needs more than a stack trace.
• Agent Identity: Fingerprinting, CAPTCHA flows, and partner-specific behavior take ongoing work, not a one-time flag.
• Proxies and routing: Geo, residential vs datacenter, rotation, and failure handling are their own product surface.
• Chromium lifecycle: Pinning versions, security updates, and rollout strategy across environments.
• Security isolation: Agents visit untrusted pages, so prompt injections and malicious content can turn the browser into an attack surface. Without per-session sandboxing, you risk data exfiltration, environment probing, and lateral movement inside your VM.

What Browserbase gives you

Browserbase absorbs that operational surface so your team can focus on agent logic:

Understanding the performance numbers

Raw timings depend on what you measure: create vs connect vs first navigation vs teardown, and whether you reuse the default context/page or create new ones. Things that routinely move the needle vs a minimal local benchmark:

• Network: Remote sessions add RTT; local Chromium uses near-IPC latency.
• Hardware: Your laptop or CI runner may have more CPU/RAM than a generic hosted shape.
• Features: Session recording, screencast setup, Verified, and proxies add real work; disable or align defaults when you want apples-to-apples comparisons.

Local vs managed at a glance

Once you need reliability, parallelism, shared debugging, or Agent Identity across a team, managed sessions usually win on total cost.
