FreeBuff exits with SIGILL - CPU does not support AVX2 required instructions

Bug Report: FreeBuff exits with SIGILL - CPU does not support AVX2 required instructions

Description

Freebuff fails to run immediately on my system. The binary exits with SIGILL (illegal instruction) because my CPU does not support AVX2 instructions. This prevent me from using freebuff at all.

I really want to try freebuff for personal practice projects, but I cannot run it due to CPU incompatibility.

Error Message

freebuff exited immediately (signal SIGILL)home/myuser/.local/share/pnpm/bin" is not in PATH
Your CPU may not support the required instruction set (AVX2).
This typically affects CPUs from before 2013.
Unfortunately, this binary is not compatible with your system.

Expected Behavior

Freebuff should be able to run on CPUs without AVX2 support, or at least provide:

• A precompiled binary without AVX2 requirement (generic x86_64 version)

Actual Behavior

The program immediately exits with SIGILL error. I cannot use freebuff at all.

System Information

• Operative System: Linux (not windows)
• CPU architecture: x86_64 (no AVX2 support)
• Installation Method: pnpm install -g freebuff

Steps to Reproduce

1. Install freebuff with pnpm install -g freebuff
2. Run frebuff
3. Program immediately exits with SIGILL/AVX2 error

CPU Verification

My CPU does not support AVX2. Running: bash grep -m1 avx2 /proc/cpuinfo
Returns nothing (confirming not AVX2 support).

Additional Context

I cannot use freebuff at all right now due to this CPU restriction.
I really want to use freebuff because it's free, no account required, and perfect for personal projects. But I need a version that works on older CPUs.

Thank you for your work on freebuff! I hope you can add support for CPUs without AVX2.

Try running npm i -g freebuff and then freebuff again.

I added a new compiled bun target for older PC's. But I'm not 100% sure it is working haha. Let me know!
