Agentfly vs Windsurf, now Devin Desktop

Windsurf, renamed

On 2 June 2026 Cognition renamed Windsurf to Devin Desktop and shipped the change as an ordinary update, keeping each user's plan, extensions, keybindings and settings. The default screen became the Agent Command Center, a board of local and cloud agents, with the full editor behind it. Cascade, the agent Windsurf was known for, was retired on 1 July 2026 in favour of Devin Local.

If the change is what sent you looking for a Windsurf alternative, the useful question is the one underneath it: whether you want your AI on a vendor's allowance, or on your own key.

An allowance against your own key

A plan's allowance is counted in a unit the vendor defines and can redefine. It bundles the model call, the vendor's margin and the vendor's view of what a request is worth, which makes a month's bill hard to predict and harder to compare.

With your own key there is one price, the provider's, and one limit, your account's. If a provider cuts its prices you get the cut the same day; if a better model ships you switch in settings rather than waiting for an editor to offer it. Nothing about the arrangement depends on an editor vendor keeping its current plans.

What the agents do in Agentfly

The assistant reads your project, makes exact edits across several files, runs your tests and type checks, and carries on until the job is done. Every turn that changed files gets an Undo card, so letting it act is safe rather than brave.

For bigger jobs the Agents board runs several agents at once, each in its own copy of the project, and shows what each ran as proof of work - the tests and checks, with a tick or a cross. Race mode hands one task to two or three models and lets you keep the best attempt, which is the fastest way to find out which model suits your codebase.

Where Devin Desktop is genuinely ahead

Its link to Devin's cloud agents, and the time Cognition has spent tuning its agents against a large user base. Compatibility with VS Code extensions and keybindings also means more of an existing setup carries over unchanged, which some people value more than anything else on this page.
