A coding agent’s memory outlives its machine
Open SWE remembers the patch after its machine expires. Our provider checks that it can reach the same files, but a timeout default and a broken deletion helper still need work.

Notes on building and using agent compute, with links to the contracts and code behind it.
Open your mainbrella with two hands
Our OpenHands prototype can connect to a running workspace, but it can’t yet refresh an expired access URL. That gap belongs in the provider interface.
When It Rains Agents, Bring a mainbrella
Mastra’s file tools and commands use one Linux workspace. Dropped output streams can reconnect, but the adapter still hits a limit after 32 quick commands.
New batteries for the batteries-included agent harness
We connected Deep Agents’ file tools and shell to Mainbrella. Keeping cleanup away from a replacement machine takes more than remembering its slot.
The benefits of rain
You can fork Mainbrella and sell a competing service. We think the hosted version should earn its fee by handling the work of running it.
When the machine boots but the reply disappears
The machine started, but your client never heard back. Follow a Python job through launch retries, delayed cleanup, dropped streams, and a saved disk.
