Siril Cloud local client

The Siril Cloud desktop client watches any folder your camera tethering software writes to (NINA, APT, ASIAir, Ekos, or similar), compresses FITS frames with fpack -q 4, uploads them, and submits a Siril stacking job.

Install

pip install siril-cloud
siril-cloud

The local dashboard opens automatically at http://localhost:9559. Set SKIP_BROWSER=1 to suppress the auto-open (useful for headless/CI use).

Storage providers

• Built-in S3 — direct presigned uploads authenticated with the Siril Cloud API key. The client preserves the exact upload prefix and sends it with the job.
• Google Drive — connect Google Drive in the web dashboard. The local Settings panel lists available Drive folders; no manual folder-ID copy/paste is required.

OneDrive and Dropbox are displayed as coming soon until their production OAuth providers are enabled.

Other features

• Watches for raw camera files and FITS files.
• Compresses FITS files losslessly with fpack -q 4; raw files are converted by the worker.
• Auto-submits when watching stops after at least five frames.
• Detects a nearby deployed compute region automatically, with a manual region override.
• Persists configuration, upload de-duplication, and an unfinished batch across restarts.
• Shows upload errors and job-submission results in the UI instead of browser alerts.

Built on open-source Siril.
