What cloud agents do you use?

I want something like the agent sidepanel in VS Code/Cursor that runs in the cloud, not on my laptop. I want to choose the model, chat with it on my way into work or from the couch, and get a PR when it's done.

Cursor Cloud Agents works the best, but I think the rest of the Cursor product sucks. Claude Code Web seems abandoned, GitHub Copilot is buggy and regularly cannot see its own chat history, and products like Devin are so focused on token and model indirection that I don't trust the cost-per-task.

Someone has to have good cloud agents. What are you all using?
