According to G2's pricing data for Kong Insomnia, a free trial is available for evaluation, but Kong Insomnia does not offer a permanent free tier. G2 reviewers consistently flag this as a pain point: multiple users note that team collaboration and collection-sharing features are locked behind paid plans, and one reviewer explicitly states there are no open-source options for sharing. Core API testing, environment management, and Git integration are accessible, but advanced collaboration, enterprise-scale features, and deeper organizational controls require Kong Insomnia's paid plans. Enterprise needs are addressed through custom quotes. The absence of a free tier is a recurring complaint, particularly among small business reviewers.
