Ampere 2
FreeThe same small player, rebuilt with its own audio engine. A third of the download, a faster start, and fully usable from the keyboard — at the cost of the equalizer and some rarer formats.
- Windows 10 / 11
- Portable
- 23 MB
Tessera
Your C: drive is full and Explorer will not tell you why. Tessera draws the whole disk as a treemap — the 40 GB thing you forgot about becomes the biggest block on screen. Then deletes it safely.
- Windows 10 / 11
- Portable
- One file
NetScanner
Point it at a range and it works out what is on your network — names, MACs, vendors, open ports, live services — streaming each finding into the grid as it arrives instead of making you wait for the sweep.
- Windows 10 / 11
- Portable
- No admin rights
Ampere
FreeA small audio player in the spirit of the compact players of the Winamp era. Plays almost anything you own, sits in the corner of the screen, and cannot reach the network even if it wanted to.
- Windows 10 / 11
- Portable
- One file
What they have in common
None of these are trial versions of something bigger, and there is no upgrade tier. They are finished tools.
-
One portable file. Nothing is installed and no runtime is
required. Copy it to a USB stick and run it anywhere. Ampere 2, Ampere and
NetScanner keep their settings and saved results in
%APPDATA%, and nothing else; Tessera writes nothing outside its own folder at all. - No telemetry. No account, no licence server, no analytics, no update pings. None of them send anything anywhere about you — and Ampere 2 and Ampere are built without any networking components at all.
- Free, or bought once. Ampere 2 and Ampere are free. Tessera and NetScanner are one-time purchases through Gumroad — no subscription, no seat count, no expiry.
- Runs as a standard user. No administrator prompt, no kernel driver, no service left running in the background.
Built to be used, not admired
Each one is honest about its limits — what it could not read, what it could not reach, and what a result does and does not prove.
