Stay free if you only need basic features. Upgrade if you need advanced features. Most solo builders can start free.
The free plan of 21st.dev typically includes basic features with usage limitations, while paid plans offer advanced features, higher limits, priority support, and additional integrations. The specific differences depend on their current pricing structure.
Consider upgrading to a paid 21st.dev plan if you're hitting usage limits, need advanced features, require priority support, or want access to additional integrations. Upgrade when the tool becomes central to your workflow and the additional features provide clear value.
Free plans typically have limitations on usage quotas, feature access, support availability, and integration options. These limitations are designed to let you test the core functionality while encouraging upgrades for serious usage.
If 21st.dev offers a free tier, you can typically use it indefinitely within the usage limits. If it's a free trial, the duration is usually clearly stated (commonly 14-30 days). Check their terms of service for specific details.
Start with the free plan — upgrade when you need more.
