However, following the release of version 8.0, numerous bugs have surfaced, with Insomnia app data loss being the most significant issue. Personally, I lost all my data after Insomnia automatically updated. Other users have encountered problems like errors importing data and non-functional double-click renaming.

Furthermore, the offline support that was once a feature in Insomnia has been replaced by an online-only usage model. These issues in the 8.0 version have significantly impacted the user experience. In this article, we will explore the top 10 Insomnia alternatives, providing a comprehensive overview of their features, advantages, and drawbacks.
