How we order apps
Popularity reflects interest in this catalogue, not a review or a safety rating. We count installer transfer starts and visits to official download websites or web apps equally. We cannot confirm downloads completed on another website.
The last 30 days inform the order, with recent activity carrying more weight. Repeat actions count once per app and UTC day, using a protected network fingerprint where available, or an anonymous browser identifier. Shared networks may be undercounted. Known bots, privacy opt-outs and unusually broad activity are excluded.
Discovery gives some earlier positions to new and less-seen apps. Popularity keeps the strict interest order; A–Z lets you browse by name. Lists update hourly, show the same order to everyone, and retain an editorial fallback when data is unavailable. No paid placement is included.

Choose by the job you need to do
- Find files: compare filename indexing with full-content search; check supported drives and filesystems.
- Work with archives: distinguish formats a tool creates from those it only extracts. Check password protection and filename encryption separately.
- Transfer files: prefer SFTP or FTPS when supported and protect saved credentials.
- Diagnose networks: compare discovery, scanning and export features. Scan only systems you own or have permission to assess.
Before you install
Check the operating system, architecture, licence and release details. Back up important files before modifying or encrypting data. See what freeware means for the differences between freeware, free tiers and open-source licences.
Good to know
Are these tools free for business use?
Not necessarily. A free download does not guarantee commercial-use or redistribution rights. Check the publisher's current licence before deployment.
Where do downloads come from?
Each listing links to its publisher. Some also offer a catalog-hosted installer with file details. VirusTotal results are an additional signal, not a safety guarantee.
