Agentfly vs VS Code vs Cursor: an honest comparison

People choosing an editor are really choosing a bundle: editing core, language intelligence, AI, and ecosystem. Here is how Agentfly stacks up against the two defaults, claimed plainly enough to be checked.

The editing core

VS Code and Agentfly share a heritage: both build on Monaco, the editor component behind vscode.dev. Folding, multi-cursor, minimap, sticky scroll, bracket colourisation, indent guides - the muscle memory transfers one-to-one. Nobody switches editors over these; the differences are elsewhere.

Language intelligence

All three speak LSP. The difference is philosophy: VS Code routes intelligence through its marketplace extensions, Cursor layers its fork over VS Code's model, and Agentfly talks to the language servers already installed on your machine - rust-analyzer, typescript-language-server, whatever your language's docs recommend - plus one config line for anything unusual. You use the exact servers the CLI tools use, with no marketplace deciding what is available.

Debugging tells the same story: Agentfly includes a debug adapter client wired for JavaScript, TypeScript, and Python out of the box, and says so honestly for languages it cannot debug rather than showing dead buttons.

The AI question

This is where the products genuinely diverge:

• VS Code offers GitHub Copilot - a limited free tier, paid plans above it - inside the extension model.
• Cursor is a subscription product built around hosted models - the bundle IS the business model.
• Agentfly is bring-your-own: connect Anthropic, OpenAI, Google, any OpenAI-compatible gateway, or a local model via its address. Keys live in your OS keychain, conversations stay in files on your disk, and the memory the assistant keeps is plain markdown you can read and delete. Its agents edit across files, run your tests and keep going until the job is done; several can work at once on the Agents board, and every turn that changed files can be undone.

No vendor lock-in cuts both ways: you manage your own keys and see the provider's raw pricing instead of a bundled margin.

Privacy posture

All three will tell you they respect privacy; compare the mechanics. Agentfly's ad targeting reads 45 compiled-in tags about what is open - no filenames, paths, or contents ever leave the machine, and there is no request field where they could ride along. Chat context stays local unless you connect a cloud provider yourself, and even then it is per-project, reviewable, and clearable.

Ecosystem

Here VS Code wins and we will say so: hundreds of thousands of extensions beat dozens. Agentfly's counter-argument is that the extensions people actually install - formatters, linters, themes, keymaps - are largely built in and on by default. Check what remains of YOUR extension list after subtracting those.

The part nobody else has

Both other editors are free-or-subscription. Agentfly inverts the ledger: a sponsored card appears a few times an hour, at the edge of the window and never in the way of the caret - and half of every advertiser payment lands in YOUR account, on an append-only ledger you can audit row by row. Not a salary - but no other editor pays you anything, and none lets you turn its business model off without losing features.

The honest scorecard

Choose VS Code for the ecosystem, Cursor for a managed AI experience you pay monthly for. Choose Agentfly for built-in tooling with no extension ritual, AI on your own key with no markup, a hard privacy ceiling - and an editor that pays you back for the interruption it asks.
