Falkon 25.04.1 — the first minute without a single click
How we tested: a clean Debian 13 in a disposable container; source — package falkon 25.04.1-1 from the Debian repository. Run as a regular user on a virtual screen, 60 seconds, nothing clicked. 16.10.2026. Every network request and every file written was recorded; the code was not decompiled. The container was deleted afterwards.

Where it connected

raw.githubusercontent.com | connection | 1.5 | 1 | — |
A DNS lookup is not yet a connection: the program looked up the server’s address. But the lookup itself is visible to the ISP and the DNS server.
What it wrote to disk
Folders the program wrote files to during the minute:
| Folder | Files |
|---|---|
~/.cache/mesa_shader_cache_db | 102 |
~/.config/falkon | 39 |
~/.cache/qtshadercache-x86_64-little_endian-lp64 | 2 |
How to read this card
- This is the first minute after launch with no action at all: what the program does on its own. Normal use may involve more requests.
- A “built-in SDK” means the library’s code was found. It does not prove data transfer, and an address in the code is not a request.
- The review was made automatically using a single method. You can check any program yourself here.
