Agentfly vs VS Code: a free alternative, AI agents built in

Agentfly vs Visual Studio Code

Both editors are free and both are built on Monaco, so the editing feels familiar moving either way. The real differences are three: Agentfly has AI agents and a full git workflow in the box rather than through extensions, Agentfly pays you a share of its advertising revenue, and VS Code has an extension marketplace that Agentfly cannot match.

What carries over on day one

The editing surface is the same one, so the muscle memory transfers: the command palette, multi-cursor, the go-to-symbol behaviour, and the keybindings you have internalised all work the way you expect. This is not a coincidence of design; it is literally Monaco in both cases.

Open VSX extensions install normally, which covers most language servers, themes, and formatters. What does not carry over is anything Microsoft publishes only for its own builds.

What Agentfly adds

The difference in practice is how much you have to assemble yourself. A working VS Code setup is usually the editor plus a dozen extensions, each with its own settings and its own upgrade risk. In Agentfly the AI, the git history, the terminals, the preview server and the collaboration are all in the box and configured together.

And it pays. Every sponsored card credits you half of what the advertiser paid, on a ledger you can read. Over a year that is roughly the difference between paying for an editor subscription and being paid a little for using one.

Where VS Code is genuinely ahead

The marketplace, and it is not close. Fifteen years of accumulated extensions is not something a new editor competes with, and pretending otherwise would be the sort of claim that makes the rest of this page not worth reading.

Microsoft's first-party language packs are the sharpest edge of that. They are licensed for Microsoft's own builds, so no third-party editor can ship them - and for C#, C++, and some Python workflows they are meaningfully better than the open alternatives.

Agentfly compared with Visual Studio Code

A feature-by-feature comparison of Visual Studio Code and Agentfly
	Visual Studio Code	Agentfly
Price	Free. Funded by Microsoft as a strategic loss-leader.	Free. Funded by advertisers, who pay you half of what they bid.
Editing surface	Monaco.	Monaco - the same one, so keybindings and editing behaviour carry over.
AI	GitHub Copilot - a limited free tier with paid plans above it - or a third-party extension you configure.	Built in: agents that edit across files and run your tests, on your own key from four providers or any OpenAI-compatible endpoint. No markup, no request cap.
Git	Built in, with blame and history usually added by extension.	Built in: stage, commit, branch, blame, and a browsable commit history.
Compiler errors	Shown as the compiler wrote them.	Also rewritten into plain English, with the original kept alongside.
Extensions	Tens of thousands, including proprietary Microsoft ones.	A far smaller set. This is the honest gap.
Telemetry	On by default; opt out in settings.	Ad targeting uses 45 generic tags. File contents, paths and project names never leave the machine.
Earnings	None.	About $0.001 per impression, on an append-only ledger you can audit.

Common questions

Is Agentfly a fork of VS Code?

No. Agentfly is built on Monaco, the same editing component VS Code uses, but it is a separate application rather than a fork of the VS Code shell. That is why the editing feels familiar while the surrounding features differ.

Can I use my VS Code extensions in Agentfly?

Extensions published to Open VSX install normally, which covers most language servers, themes, and formatters. Extensions Microsoft publishes only for its own builds - the C++, C#, and Remote Development packs among them - are licensed so that no third-party editor can ship them.

Is Agentfly better than VS Code?

For AI, git history, and cost recovery, Agentfly does more in the box. For extension breadth and Microsoft's first-party language tooling, VS Code is ahead and will stay ahead. If a specific proprietary extension is load-bearing for your work, that decides it.
