Important Notice: Transition to Dedicated Support Repositories

Starting with release v0.2.0, Thisma Labs has organized customer support, release feeds, and issue tracking into two dedicated, platform-specific public repositories:

• Windows Desktop Support: https://github.com/thisma-labs/beside-windows-support
  Live Help Center: https://thisma-labs.github.io/beside-windows-support
• Android Mobile Support: https://github.com/thisma-labs/beside-android-support
  Live Help Center: https://thisma-labs.github.io/beside-android-support

This unified repository (thisma-labs/beside) continues to serve as an umbrella archive and general release distribution mirror.

What is Beside?

Beside is an ultra-fast, local-first file, folder, and text sharing application designed specifically for Windows 10 / 11 (64-bit) and Android 8.0+ (arm64).

Transfers travel machine-to-machine strictly within your local Wi-Fi network at full wire speed (up to 110 MB/s). No cloud servers, no account registration, zero telemetry, and flat 64 KB memory consumption regardless of file size.

What's New in v0.2.0

1. Dual-Platform UI Redesign with Light & Dark Theme Support

• Both Windows and Android applications feature authentic, refreshed user interfaces with automatic and manual light/dark theme switching.
• Windows Desktop: 3-column architecture designed for widescreen desktop workstations with concentric radar, drag-and-drop dropzone, and active transfer docks.
• Android Mobile: 4-tab bottom navigation (Home, Activity, Trusted Devices, Settings) engineered for one-handed touch ergonomics.

2. High-Performance Wire-Speed File & Folder Streaming

• Direct peer-to-peer TCP streaming using a bounded 64 KB RAM buffer.
• Complete nested directory tree streaming without compression latency.
• Automatic non-destructive collision avoidance: existing local files are never overwritten.

3. Mutual TLS 1.3 Encryption & 8-Digit SAS Pairing

• Every local connection is secured with Mutual TLS 1.3 using ephemeral pinned device certificates.
• Zero-MITM Short Authentication String (SAS): an unforgeable 8-digit visual code derived from the TLS 1.3 Key Exporter to authenticate new peers in coffee shops, hotels, and universities.
• Hardware key vaults: device identity keys are encrypted using Windows DPAPI and Android Keystore (TEE / StrongBox).

4. Direct LAN Text Messaging

• Send text snippets, terminal commands, URLs, and clipboard notes directly across devices without cloud messengers.
• One-tap clipboard copy on received notifications.

5. Multi-Storefront Commercial Availability

• Beside Free ($0 forever): 1 device, 1 MB outgoing file cap, unlimited incoming files at full wire speed.
• Beside Pro ($14.99 one-time lifetime): Unlimited outgoing file sizes, up to 3 personal devices.
• Available through Gumroad, itch.io, and SourceForge File Release System (FRS).
