FastCast v0.3.1 — Open Beta. Free during the open beta. A native Windows screen recorder and live streamer focused on reliable local recording and custom RTMP/RTMPS streaming.

Download

  • FastCast-0.3.1-win-x64.zip — portable, no installer. Extract and run fastcast.exe.
  • FastCast-0.3.1-win-x64.zip.sha256 — checksum to verify the download.

SHA-256: 2c56fe389f1c8204610493cee5a4b40209cef3d3dddaaedd9eda617d11a0505f

Verify in PowerShell:

Get-FileHash .\FastCast-0.3.1-win-x64.zip -Algorithm SHA256

The build is unsigned, so Windows SmartScreen may warn "unknown publisher" — click More info → Run anyway if you trust the download source.

What's new in v0.3.1

  • AMD hardware H.264 encoding fixed — AMD AMF now uses H.264 Main profile with B-frames pinned to 0, so AMD GPUs use the hardware encoder instead of falling back to software. Validated on tested Radeon RX 6700 XT and RX 7900 XTX systems.
  • Security/privacy audit cleanup completed (no high/medium findings).
  • RTMPS guidance added in the UI — plain RTMP does not encrypt the stream key in transit.
  • Update checker now uses this public release feed; manual and user-initiated only (no auto-update).

Privacy

No telemetry, no accounts, no crash upload, no background polling, no auto-update. Your stream key is never saved to disk. Support bundles are local-only and redacted. The only network activity is streaming to your chosen ingest and the manual Check for Updates.

Requirements

Windows 10 (20H1+) or Windows 11, x64. A GPU with hardware H.264 encoding (NVIDIA / AMD / Intel) is strongly recommended; a software fallback is included but slower.

Notes

Currently free during open beta; a Pro version may be added later for advanced creator features (nothing is gated today). FastCast is a focused single-scene tool — no scene system, chroma key, platform OAuth, or multistream yet.
