Why Capsule?

Create a Shareable File for Your Personal App

Capsule brings the simplicity of documents together with the power of native desktop and mobile applications.

01 / PORTABILITY

What If an App Was Just a Document?

Forget cloud accounts, servers, and subscriptions. Capsule bundles your user interface, media assets, and local database into a single, portable .capsule file.

Send it via WhatsApp, AirDrop, or email just like a PDF or Word document. When the recipient taps the file, it launches instantly with all your data preloaded, ready to use.

💬

Share Apps in Chat

Send interactive trackers, portfolios, or tools in standard message threads. Tapping open works immediately.

🎨

Zero Vendor Lock-in

Capsules use standard HTML and CSS. Your code and data belong to you, entirely free of cloud silos.

02 / PRIVACY FIRST

100% Private by Design

Capsule keeps your personal data where it belongs, on your device. Everything you create is saved directly into the file, giving you complete ownership with zero cloud servers.

Write tasks, list recipe notes, or save project logs. There is no cloud storage, no account registration, and no network requirement. Everything is secured right inside the file.

Offline-First Storage

Works 100% offline. Access your apps on a plane, on the subway, or completely disconnected.

Secure Local Vault

Data stays safely packed inside the single file. Absolute protection from server breaches.
