FKN WebExtension

Let the web apps you choose do more in your browser, read pages, act on sites, always behind your permission.

FKN is the companion browser extension for the FKN platform (https://fkn.app), a privacy-first platform where the web apps you use can do more in your browser, and the cloud is an option rather than a requirement. By itself this extension does nothing visible. It is a capability provider: it lets a web app you choose, and explicitly authorize, act on other websites on your behalf, and only ever after you allow it. Think of it as a permission-gated automation bridge between an app you trust and the sites you tell it to work with. What an authorized app can ask FKN to do for you: - Embed another website inside the app's own view, and restyle it. - Read elements on a page (for example, the text or state of a control). - Act on a page on your behalf: click a button, fill in a field, control video playback. - Relay your own already-logged-in session into the app (for example, play a video through a subscription you already pay for), without handing the app your password. You are always in control: - Every sensitive capability is shown to you and asks for your consent before anything happens, described in plain language, per app and per capability. - You decide whether to allow an action once, for the session, or always. - An "area" grant lets you approve a whole region (such as a media player) once, instead of being asked for every individual control. - Every capability an app uses is written to an on-device activity log (kept 30 days) that you can review, and you can revoke any grant at any time, per app and per capability. Your data, your device: - There is no account, no analytics, and no tracking. - No remote code: everything, including any WebAssembly, ships inside the package. - Nothing leaves your device except the specific action you approved, sent to the website it targets. Your permission grants and your activity log stay on your machine. Try it with no login or account, in under a minute: https://fkn.dev/playground/web-extension/guided/ That page embeds the real Wikipedia, restyles it, and then, after a single consent prompt, types a search and clicks Search, so you can watch exactly what the extension does and see each action appear in the activity log.
