Action! vs ControllerBuddy

Action! by Mirillis is a Windows screen and gameplay recording tool built for capturing DirectX, OpenGL, and Vulkan games in high definition, alongside desktop activity, application windows, and web video. It supports live streaming directly to Twitch, YouTube, and Facebook, and can export finished recordings straight to YouTube or Facebook without a separate upload step. Recordings use hardware acceleration via NVIDIA NVENC, AMD APP, or Intel Quick Sync Video, along with Mirillis's own FICV codec, to keep capture performance smooth even during demanding gameplay. Additional features include a Greenscreen mode for removing webcam backgrounds, 120fps slow-motion capture, Time-Shift recording, and a companion Android remote-control app. It is sold as a single lifetime license rather than a subscription.

ControllerBuddy is a specialized controller mapping tool built to make flight simulators playable with a standard gamepad instead of an expensive HOTAS setup. It translates controller inputs into keyboard, mouse, and virtual joystick commands, with support for customizable relative axes for throttle-style controls and a multi-mode system that lets a single button perform different functions depending on the active mode. The tool supports Xbox, DualShock 4, DualSense, and any controller compatible with SDL_GameControllerDB, and works on both Windows and Linux. It's free, open source under the GPL-3.0 license, and ships with over 100 community-maintained profiles for popular flight simulators and aircraft in its official repository.

• One-time lifetime license with free updates rather than a recurring subscription
• Strong hardware-acceleration support keeps recording overhead low during gameplay
• Built-in live streaming to major platforms without needing separate broadcasting software
• Greenscreen and Time-Shift modes are useful extras not found in every competing recorder

• Completely free and open source under GPL-3.0
• Removes the need to buy a dedicated HOTAS for flight sims
• Large library of ready-made community profiles for popular simulators
• Cross-platform support for both Windows and Linux

• Windows-only, with no native Mac or Linux version
• Interface and workflow feel dated compared to newer competitors like OBS Studio or NVIDIA ShadowPlay
• OBS Studio offers comparable streaming/recording features for free, making Action!'s paid model a harder sell for budget-conscious users

• Steep learning curve for building custom profiles from scratch
• Narrowly focused on flight-sim-style control needs rather than general gaming
• No official macOS build
