About Mainbrella

Mainbrella gives AI agents a cloud computer: a Linux workspace for running commands, installing tools, and working with files. The aim is to make that workspace straightforward to create, use, and clean up from the tools developers already have.

Why this problem

An agent needs more than a model response when its task involves code. It needs a place to execute, inspect output, and move files, with explicit ownership and a lifecycle that does not leave machines running indefinitely. Mainbrella brings those operations into one account-owned HTTP workflow.

What you can use today

Create containers with idempotent requests, execute commands over HTTP, read and write files, choose a deployed runtime image, or build a custom image when builds are enabled. For interactive work, connect through SSH or the browser terminal. Named API keys and an agent skill support automation.

Mainbrella builds on Cloudflare Containers for workload isolation and compute. Mainbrella provides the account, API, lifecycle controls, and billing experience. Read the security overview and current limits.

Where it is going

Mainbrella is early. The focus is making agent execution dependable and easy to integrate, from the first API call through cleanup. The changelog records what's shipped; tell Andrew which workloads and capabilities would make it useful for you.
