Fast native desktop client for all major web services

Download beta 0.52

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 200 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 messenger's website.

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 or any plans to introduce 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 it really only 200 KB? Or is it just an installer that downloads another 200 MB?

No, it's not an installer. The entire app fits into a ≈200 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.

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 doesn't send any of your data to us or any third party. This can be easily verified with tools like Wireshark and tcpdump.

A security audit by an external security company will be performed in the future.

Volt is a registered company, and all binaries are signed.

Is there a mobile app?

Right now the focus is on the native desktop clients. Development of Android and iOS apps will start in mid 2019.

I spent most of the day working on the Windows build for the planned Feb 13 release.
Unfortunately I'm not satisfied with the quality of the build. I'm also moving house tomorrow, so the release is going to be postponed by 2 days.
Sorry about that.
