Vibefuel for VS Code and Cursor

See sponsored messages in your coding workflow and earn Solana tokens to put toward your next AI credits.

Vibefuel shows one clearly labelled sponsored card at a time, only in its own sidebar view. Advertisers fund the tokens; you decide when it runs. Nothing is injected into your editor, your chat, your completions or your terminal.

Vibefuel is an independent product. It is not affiliated with, endorsed by or partnered with the makers of VS Code, Cursor or any AI assistant.

Install

VS Code

Open the Extensions view (Ctrl+Shift+X / Cmd+Shift+X).
Search for Vibefuel and click Install.
Or from a VSIX: code --install-extension vibefuel-0.1.0.vsix.

Cursor

Cursor installs extensions from Open VSX, where Vibefuel is also published.

Open the Extensions view in Cursor.
Search for Vibefuel and click Install.
Or from a VSIX: Extensions view → … menu → Install from VSIX…, or run cursor --install-extension vibefuel-0.1.0.vsix.

Vibefuel uses only the stable VS Code extension API, so it behaves the same in both editors.

How it works

Opt in. On first launch the Vibefuel view opens with a plain explanation of what is shown, collected and earned. Nothing runs until you click Opt in. Opting out is one click in the same view and clears all state.
Sign in with your Vibefuel key. Create a free Vibefuel key at vibefuel.app (no email, no password) and paste it when the extension asks. The key is stored in your editor's secret storage and links this editor to your dashboard.
Sponsored cards. At most one new card every 30 minutes, none in the first 10 minutes of a session, none while debugging, none while the window is not focused, none while paused.
Earn. A view counts after the card has been visible for 3 continuous seconds with the window focused. The reward is shown on every card as Earn N tokens. Clicking the CTA opens the advertiser in your browser; nothing is ever auto-opened. Not interested dismisses the card. The server rewards each advertiser at most once every 6 hours and only from a funded campaign budget.
Payouts. Link a Solana public address to receive payouts. Vibefuel validates the address and sends only that public address to your account. Payouts start at 100 tokens from your dashboard.

Tokens can be put toward your next AI credits. Vibefuel does not buy credits on your behalf and does not claim to cover your costs.

Privacy

The same summary is shown inside the extension under What Vibefuel collects.

Collected

Your Vibefuel key, to tie events to your dashboard. Stored hashed on the server.
Ad events: impression, click and dismiss, each with the campaign id, a timestamp and a random per-session id
A heartbeat about once a minute while the editor window is focused: editor name, extension version and active seconds. Shown as hours of work on your dashboard.
Extension version

Never collected

File contents, file names, project names or paths
Prompts, chat messages or AI completions
Keystrokes or clipboard
Git remotes or identities

Rules

Events are batched and sent at most once per minute. The queue is dropped on opt-out and sign-out.
If editor telemetry is disabled (telemetry.telemetryLevel is off), no events are sent at all. The sidebar tells you that views cannot be rewarded.
Only a Solana public address is stored, in the editor's SecretStorage. You can unlink it at any time.
In mock mode (vibefuel.apiBaseUrl set to mock) no events or ids are sent anywhere; they are written to the Vibefuel output channel. Card images still load from their https URL.
The full summary is at vibefuel.app/privacy.

Mock mode and the API contract

The backend is defined by packages/vibefuel-core/api/openapi.yaml (OpenAPI 3.1) in the Vibefuel repository. Client types are generated from it with npm run generate:api in that package. The adapters, delivery policy and validation live in the shared @workspace/vibefuel-core package so the Claude Code plugin uses the same code and the same balance. Two adapters implement one interface:

MockAdapter (vibefuel.apiBaseUrl = mock): serves five clearly fictional ads, keeps the balance locally and logs events to the Vibefuel output channel.
HttpAdapter (default, https://vibefuel.app): the web app in apps/web serves the contract. If the host cannot be reached the sidebar shows an offline notice and retries quietly; no error dialogs are shown.
