Legba vs Browserbase

A Browserbase alternative built on isolation.

Browserbase gives agents a browser in the cloud. Legba gives them a disposable one: a real headful Chromium on a fresh residential IP, destroyed the moment the session closes.

If your agents get blocked on datacenter IPs, or you do not want a credential to outlive a single job, the difference is the whole product.

When Browserbase is the better pick

Browserbase is a strong pick for high-volume, low-risk headless automation where datacenter IPs are fine and you want a mature managed browser pool. If isolation and residential exits are not requirements, its scale and ecosystem are real advantages.

Questions people ask.

Is Legba a drop-in replacement for Browserbase?
For agent and automation work, yes. Legba exposes an MCP server, an API, and a Playwright-compatible interface, so most orchestration code redirects with minimal change. The difference is the engine underneath: a real headful browser on a fresh residential IP, destroyed on close.
Why do residential IPs matter?
Many sites treat datacenter IPs as bots and block or challenge them. Legba gives each session a fresh residential exit, so the traffic reads as a real person on a real network. Browserbase runs on datacenter IPs by default and sells residential as an add-on.
What happens to credentials and cookies after a run?
They live inside the session container and are destroyed when the session ends. Nothing persists unless you ask for an encrypted state blob under your key. A prompt injection or a leaked token has nowhere to go after close.
Does Legba support headful rendering for vision models?
Yes. Legba runs real headful Chromium, so a vision model sees the page the way a human would. Headless rendering can drop or reflow content that a vision agent then misreads.

Access anything.
Expose nothing.

Legba is a disposable real browser: it spawns a clean session, does the work, and destroys itself on close.
