Freeware means no-cost use, not access to source code. Open source permits inspection and reuse under its license. Freemium reserves some features for paid plans; commercial products require their own terms. Hosting, support, plugins and model licenses can still cost money.

VLC
Play local videos and audio without assembling a collection of separate players.
Platforms
Windows · macOS · Linux
Guidance & sources
Try your usual media files and subtitle tracks first.
Edition and requirements can change; check the official source before installing.
VLC plays media; Audacity edits audio; OBS Studio records or streams; HandBrake converts video. These tasks are different. Keep the original recording, test a short export and check codec compatibility before processing a large collection.

Platforms
Windows
Guidance & sources
Useful for editing plain text; keep document formatting work in an office application.
Edition and requirements can change; check the official source before installing.
Begin with an editor, Git and the runtime your project actually uses. Notepad++ is a lightweight Windows text editor; VS Code supports extensible projects; Python is a language and runtime, not an editor. GitHub hosts collaboration around Git; containers and extra terminals can wait until needed.

Platforms
Windows · macOS · Linux
Guidance & sources

Edition and requirements can change; check the official source before installing.
Try a real document before replacing an office suite: fonts, macros and complex layouts may differ. LibreOffice covers writing, spreadsheets and presentations; Joplin organizes notes, while PDFsam Basic rearranges PDF pages. Microsoft Office can remain a compatibility reference without being your only option.
Create ZIP or 7z archives and extract downloaded bundles on Windows.
Platforms
Windows
Guidance & sources
ZIP is convenient for sharing; check that recipients can open less common formats.
Most code is LGPL; BSD components and unRAR restrictions also apply.
ZIP is widely exchangeable; 7z is useful when both sides have a compatible extractor. RAR extraction and RAR creation are different capabilities. Keep the original archive and extract unfamiliar bundles into a separate folder; an archive does not make its contents trustworthy.

Platforms
Windows · macOS · Linux
Guidance & sources
Compare essential websites, extension availability and tracking settings on your own device.
Edition and requirements can change; check the official source before installing.
Test your essential websites and extensions before switching. Firefox uses a different browser engine from Chromium-based choices.

Run compatible language models locally; explicitly distinguish local models from optional cloud models.
Platforms
Windows · macOS · Linux
Guidance & sources
Start with a small local model and check whether cloud functionality is enabled.
Disable optional cloud features when you require a local-only workflow. Model licenses are separate.
Local AI runs model inference on your own device. After downloading software and models, supported local workflows can work offline; cloud features and extensions may still send data. RAM is system memory, VRAM is GPU memory. CPUs can run some models more slowly; a compatible GPU can accelerate supported workloads. Larger models require more memory. Quantization uses fewer bits to reduce size, trading some accuracy for easier running. Start small, check model licenses and measure on your actual machine.
Build visual AI workflows using nodes; expect more setup than a one-button image service.
Platforms
Windows · macOS · Linux
Guidance & sources
Begin with a documented workflow; custom nodes and models need their own review.
