Frequently asked questions
Most free app builders offer limited free tiers that let you build and test apps. However, publishing to app stores, removing branding, or handling significant traffic usually requires upgrading to a paid plan.
It depends on the platform. Some free tiers restrict publishing entirely, while others allow it with branding watermarks. Goodspeed lets you build and test for free, with publishing available on paid plans.
Common limitations include user caps, storage limits, mandatory platform branding, restricted API calls, and no custom domain support. Read the fine print before committing to a platform.
