Flare is an unofficial app that lets you chat with your friends on Signal from Linux. It is still in development and doesn't include as many features as the official Signal applications.

• Linking device
• Sending messages
• Receiving messages
• Replying to a message
• Reacting to a message
• Attachments
• Encrypted storage
• Notifications, optionally in the background

More features are planned, blocked, or not-planned. Consult the README for more information about them.

Please note that using this application will probably worsen your security compared to using official Signal applications. Use with care when handling sensitive data. Look at the projects README for more information about security.
