Stay up to date with our latest MCP tools, enterprise security features, gateway performance optimizations, and developer experience enhancements.
Introducing the multi-channel GTM Pulse orchestration tool, enterprise-grade AES-256-GCM credential encryption, and a standardized high-contrast Dark Emerald design system.
Single-prompt orchestration across HubSpot, SendGrid, X (Twitter), and web analytics to automate growth workflows without writing multi-agent pipeline glue code.
Upgraded payload security with hardware-isolated AES-256 encryption at rest, automatic key rotation, and explicit Zero Data Retention guarantees for proxied payload bodies.
Refined visual hierarchy, standardized dark emerald glassmorphism, and improved text contrast across the API Key Manager, Playground, and Observability dashboard.
