ANSWER

Where do I download VNISH firmware?

Why the source matters more than the file

• A firmware image writes itself into the controller of a device that costs thousands and runs unattended. A file from a chat group, a file hosting link, a repack or an "unlocked" build has no published checksum behind it, so there is nothing to compare against and no way to tell what changed.
• A build with no published SHA-256 is not a build, it is a risk.

The route from the site to the device

• Open the firmware finder and give it your model.
• The finder resolves the exact build for your control board, because model plus control board plus install method is what decides the file.
• Download the build and verify its SHA-256 locally before it touches the device.
• Locate the rollback path for your exact board.
• Install from your own network, about fifteen minutes per device.

What it costs

The build is FREE OF CHARGE to download and to test. No licence key, no trial timer. A small share of active hashrate applies only while the firmware is actually running - no installation fee, no penalty if you stop - and it stays visible in the dashboard. On a well-matched ASIC the gains normally outweigh it several times over.
