AkastroidBuy it once.
Keep it.
No subscription. The tools you are comparing against are free, so charging monthly for this would be difficult to justify — and we would rather not try.
Free
Enough to know whether it works for you.
No account, no card, no upload.
- Every processing feature
- Deep sky and planetary
- FITS, camera RAW, SER and AVI
- Up to 25 frames per session
- Export to JPEG and PNG
Pro
For real sessions and real prints.
One computer, any platform. Move it whenever you like.
$49 for the first 500 licences sold, then $99. The price you pay is the price forever — it does not renew, and it is not an introductory rate that goes up on you.
- Unlimited frames per session
- 16-bit TIFF and FITS export
- Batch a whole folder of targets
- Drizzle and mosaic stitching
- Photometric colour calibration
- Gift artwork mode
- Every 1.x update, forever
- macOS, Windows and Linux builds
7-day refund, no questions asked — 14 days if you are in the UK or the EU, where the law says so. Pro is a one-time payment, and every 1.x update is included for as long as you use it.

How it compares
Honest version: most astrophotography software is free. Akastroid is worth paying for only if your time is worth more than the learning curve.

If you already know PixInsight, keep using it — it will always go further than we do. Akastroid is for the evening you would rather look at the picture than learn the software.
