The first public beta has been released for macOS.

It's been downloaded by more than 3000 users in less than 10 hours!

Many people are reporting crashes. Windows version will be released in the next couple of days after these major issues are fixed.

Blazing fast Volt can handle hundreds of thousands of messages without lag. You can scroll to any point in the conversation instantly and search across thousands of messages in milliseconds.
Light Volt is a native desktop app that weighs about 300 KB and has minimal CPU and RAM usage.
All chats in one place You no longer need a dozen apps to reach all your contacts across various platforms.


What language is Volt written in?

V. It's a new language I created to develop Volt. You can read about it here.

Volt uses native UI APIs: (Cocoa on macOS, Win32 API on Windows, GTK+ on Linux).

Are my passwords secure?

Volt doesn't ask for your passwords and doesn't store them anywhere. Authentication is performed in a browser directly on the platform's website.

Is it really only 300 KB? Or is it just an installer that downloads another 300 MB?

No, it's not an installer. The entire app fits into a ≈300 KB ZIP archive, and the only extra thing it downloads is ≈300 KB of high res icos, which are not required for the app to work.

In the age of 300 MB chat clients and 10 MB web pages we started to forget how powerful our computers are and how much can fit in 1 MB. A lot of time and resoures were spent to ensure the small size and great performance.

How much does it cost?

Volt will always be free.

Is my data sent anywhere or shared with anyone?

No. Volt stores your messages and contacts on your machine for offline use and better performance. That's it.

Are there ads?

No, Volt will always be ad-free.

You don't have ads, and you don't sell user data. What is the sustainability model?

Hopefully as Volt grows, it will get more supporters on Patreon. There will also be an affordable premium plan for things like having more than 5 accounts. The base functionality will always be free.

Is Volt open-source?

Not at the moment. Right now the development model is similar to that of Sublime Text. The app is going to be open-sourced in 2021.

If Volt is not open-source yet, how can I be sure my messages and accounts are secure?

The plan behind Volt is to build a light, fast, and reliable client for millions of users, not to spy on your data or sell it.

Volt is a registered European company, all binaries are signed by the company certificate. Violating your privacy by sharing or analyzing your data is a criminal offence.

Is there a mobile app?

No, sorry, right now the focus is on the native desktop clients.
