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](/integrations/skills/introduction) 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: | DIY burden | Browserbase | | - | - | | Session lifecycle & pooling | Managed sessions with clear APIs and Dashboard visibility | | Crashes & concurrency | Browserbase tunes hosted infrastructure for parallel browser workloads | | Debugging | [Live View](/platform/browser/observability/session-live-view) for real-time inspection; [session replays](/platform/browser/observability/session-replay) for replay in the Dashboard | | Agent Identity | [Verified](/platform/identity/verified-customization) and [Agent Identity](/platform/identity/overview) | | Proxies | [Proxy configuration](/platform/identity/proxies) including geolocation and routing | | Browser updates | Browserbase maintains purpose-built Chromium as part of the platform | | Security isolation | Every session runs in its own ephemeral sandbox, so a compromised page can't reach your infrastructure or other sessions | ## 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 replay, screencast setup, [Verified](/platform/identity/verified-customization), and [proxies](/platform/identity/proxies) add real work; disable or align defaults when you want apples-to-apples comparisons.
