Why Teams Move from Kentico Kontent (Kontent.ai) to Cosmic
Kentico Kontent, now rebranded as Kontent.ai, is a cloud-first headless CMS designed for enterprise content teams. Its content modeling, workflow and approval system, and multi-channel delivery have made it a reasonable choice for larger organizations. But its pricing scales steeply as your team and usage grow, and its AI capabilities remain limited compared to newer AI-native platforms.
Cosmic is built from the ground up as an AI-native headless CMS. Autonomous agents, multi-step workflows, code generation, and Slack integration are core features, not add-ons. And the pricing is transparent.
What Kontent.ai Does Well
- Structured content modeling with strong content type definitions
- Multi-channel delivery via REST API
- Content workflow and approval system for editorial teams
- Strong localization and multi-language support
- Enterprise governance and user permissions
Where Kontent.ai Falls Short in 2026
Steep price escalation. Kontent.ai's pricing jumps aggressively from entry-level plans to anything that accommodates a real team. Enterprise-level features require enterprise-level pricing, and the gap between tiers is significant.
Limited AI capabilities. Kontent.ai has added some AI features for content suggestions and translation. But it has no autonomous AI agents that create content on a schedule, write code, open pull requests, or run multi-step automated workflows.
Complex for what it offers. Many teams report that Kontent.ai's complexity relative to its out-of-the-box feature set does not justify the cost compared to newer alternatives.
Evaluation friction. Getting real pricing information requires engaging with sales, which slows the evaluation and procurement process for teams that want to move quickly.
Cosmic's Approach
Cosmic offers what Kontent.ai promises, with more AI capabilities and transparent pricing:
- Structured content modeling with typed metafields and relationships
- REST API for multi-channel delivery to any frontend
- AI agents that create content, write code, and run workflows on autopilot
- Team Agents in Slack, WhatsApp, and Telegram
- Transparent flat-rate plans that scale predictably
Cosmic's AI platform runs on Claude. Build and deploy full applications from a single prompt.
