Reputation and Real‑World Feedback

Strengths for Marketing-Oriented Sites

Neve’s white‑label mode and modular plugin integrations make it ideal for agencies or freelance marketers branding sites for clients.
Limitations and Considerations
Some users have reported difficulty processing payments due to Stripe-based checkout issues, as seen in certain Reddit discussions. ThemeIsle’s payment processor occasionally declined cards, especially when multiple cards were used in quick succession or VPNs were involved. While this is rare, users recommend verifying payment compatibility early in the buying process. Additionally, a few reviewers on G2 noted that updates can sometimes lag and a lower price point would attract more customers.
Bottom line
