When free software is enough, and when it is not
A practical line between free tools that fully solve a problem and the three situations where paying is the cheaper option.
Almost everything on InstallShelf is free, and that is not because paid software is bad. It is because for the jobs a new PC actually has, the free options are frequently the reference implementations. The interesting question is where that stops being true.
There is also a licence trap: several free entries are free for personal use only. A tool that is free at home can be unlicensed on a work laptop.
Where free is the whole answer
Archives, media playback, PDF reading, version control, text editing and most diagnostics have mature open-source tools that are not compromises. VLC, 7-Zip, Git and LibreOffice are not trial versions of something better. Paying for a commercial equivalent in these categories usually buys a different interface, not a different result.
The tools this step calls for, with their real licence and platform details:
| Program | Licence / price | Platforms | Why it is on the list |
|---|---|---|---|
| 7-Zip Publisher's site ↗ | Free · Open source | Windows, Linux | The first thing to install on any new PC. Unpacks everything, compresses better than WinRAR, and has never shipped a bundled toolbar in twenty-five years. Plain interface, zero nonsense. |
| VLC Media Player Publisher's site ↗ | Free · Open source | Windows, macOS, Linux, Android, iOS | Plays the file Windows Media Player refuses to. No codec hunting, no third-party packs, no ads. It also handles DVD, network streams and screen capture, which is more than you will ever need. |
| Git for Windows Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | Version control, plus a real Bash shell on Windows so you can stop translating commands in your head. Install it before anything else in this section. |
| LibreOffice Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | A complete office suite with no account, no telemetry and no ribbon. Opens and saves .docx and .xlsx reliably enough for everyday work. Install it even if you own Microsoft Office, as a second opinion on stubborn files. |
| Sumatra PDF Publisher's site ↗ | Free · Open source | Windows | Opens PDFs in under a second, remembers where you stopped reading, and has exactly no upsell. It also reads epub, mobi and cbz. There is nothing to configure, which is the whole appeal. |
The three reasons to pay anyway
First, when the cost is remembering: an off-site backup that runs without anyone attaching a drive is worth a subscription because the alternative is a backup that quietly stops happening. Second, when the free tier is scoped to personal use and the machine is a work machine. Third, when the workflow is specialised enough that setup time dominates the price, as with a full 3D or video pipeline.
Notice what is not on that list: speed, cleaning, optimisation, and anything sold on fear. Those claims are hard to verify and usually do not survive it.
The tools this step calls for, with their real licence and platform details:
| Program | Licence / price | Platforms | Why it is on the list |
|---|---|---|---|
| Backblaze Personal Backup Publisher's site ↗ | Paid · From $99/year | Windows, macOS | Unlimited cloud backup of one computer for a flat annual fee, including external drives. The one paid subscription on this page that most households should genuinely consider, because off-site is the part people skip. Free 15-minute restore window for the first 30 days. |
| Mullvad VPN Publisher's site ↗ | Paid · €5/month flat | Windows, macOS, Linux, Android, iOS | One flat price, no account email required, accepts cash, and has been raided by police without anything being found. The privacy purist's choice. No streaming unblocking, no affiliate programme, no marketing. |
| Blender Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | A complete 3D pipeline and a serious video editor in one download, funded by donations rather than licences. Enormous. Assume a month before you are productive in it. |
Read the licence column before you install
The table on every category page separates open source, free but closed source, free for personal use, and paid tiers. That distinction is not paperwork. IrfanView, XnView MP, Bulk Rename Utility, Obsidian and Docker Desktop all have conditions that matter the moment the machine belongs to an employer.
The tools this step calls for, with their real licence and platform details:
| Program | Licence / price | Platforms | Why it is on the list |
|---|---|---|---|
| IrfanView Publisher's site ↗ | Free for personal use | Windows | Opens a 50 megapixel photo before other viewers have finished launching. Also batch-resizes, converts and rotates entire folders. Not free for commercial use, which catches people out. |
| XnView MP Publisher's site ↗ | Free for personal use | Windows, macOS, Linux | A photo browser and converter that reads over 500 formats, with tagging and a real database behind it. Use this instead of IrfanView if you also work on a Mac. |
| Obsidian Publisher's site ↗ | Free for personal use | Windows, macOS, Linux, Android, iOS | Notes stored as plain Markdown files in a folder you own, linked together into a graph. Nothing is locked in a proprietary database, so you can walk away with everything at any time. |
| Docker Desktop Publisher's site ↗ | Free for personal use | Windows, macOS, Linux | Containers without a Linux VM to babysit. Free for personal use and small companies, but check the licence terms before using it commercially. Needs WSL2 enabled on Windows. |
Mistakes to avoid
- Assuming a free tier covers commercial use.
- Paying annually for a tool used twice a year because it felt more professional.
- Buying an optimiser or cleaner whose benefit cannot be measured on the machine in front of you.
Questions people ask
Does a paid tool get a better recommendation here?
No. Ranking and notes are editorial; the About page explains how commercial relationships are handled.
Should I donate to open-source projects I use?
If a tool becomes part of your daily work, yes. It is the cheapest way to keep it maintained.
