Is Kong worth the price?

90/100

Kong's pricing is very generous, offering a fully functional open-source 'Free' tier.

The 'Plus' tier, while custom priced, targets enterprise needs with advanced features and support. This structure is excellent for developers and small teams starting out, scaling effectively for larger organizations.

Hidden Costs & Gotchas

Enterprise support costs can be significant.

Custom pricing for 'Plus' tier lacks transparency.

Potential for high infrastructure costs.

Additional plugins might incur extra fees.

How Kong Compares to Competitors

Compared to Apigee, which starts at $500/month for its pay-as-you-go plan, Kong's 'Free' open-source offering is significantly more accessible. While both offer enterprise solutions, Kong's entry point is much lower, making it a strong alternative for budget-conscious users before scaling to custom enterprise solutions like those offered by MuleSoft.
