# Comet vs OpenWebUI

The clearest difference is price: Comet at Free against OpenWebUI's $2.99. Comet also leads on rating (4.8 vs 3.8) and ratings volume (7.8K vs 4). OpenWebUI's advantage is in-app purchases (none vs 3) and chart position (#145 vs unranked). On update cadence, ads, device support and iOS requirement there is nothing between them.

Comet is free to download; OpenWebUI costs $2.99 up front. Comet sells 3 in-app purchases, starting at $20.00 per month. OpenWebUI asks for nothing beyond the download.

Comet holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 65% of Comet's written reviews are positive against 50% of OpenWebUI's.

Comet ships an update weekly, OpenWebUI every 6 days. Both last shipped on October 20, 2026.
