Best AI Development Platforms for Close

Retool is a modern AI-native application development platform designed to help teams build internal software quickly and efficiently. It enables users to create agents, workflows, dashboards, and full-stack apps using natural language prompts and visual tools. Retool connects directly to databases, APIs, vector stores, and AI models to ensure applications work seamlessly with existing systems. The platform allows teams to transform raw data into actionable tools such as dashboards, admin panels, and monitoring systems. With drag-and-drop UI building, code-level customization, and AI-assisted generation, Retool supports multiple development styles. Built-in workflows automate complex processes while maintaining auditability and security. Retool fits naturally into standard engineering stacks with support for CI/CD and version control. Enterprise-grade permissions and hosting options ensure sensitive data stays protected. Used by thousands of companies worldwide, Retool helps teams ship AI-powered software faster. It bridges the gap between idea and production with speed and control.

Arcade.dev is a platform designed for AI tool calling that empowers AI agents to safely carry out real-world tasks such as sending emails, messaging, updating systems, or activating workflows through integrations authorized by users. Serving as a secure authenticated proxy in line with the OpenAI API specification, Arcade.dev allows models to access various external services, including Gmail, Slack, GitHub, Salesforce, and Notion, through both pre-built connectors and custom tool SDKs while efficiently handling authentication, token management, and security. Developers can utilize a streamlined client interface—arcadepy for Python or arcadejs for JavaScript—that simplifies tool execution and authorization processes without complicating application logic with the need for credentials or API details. The platform is versatile, supporting secure deployments in the cloud, private VPCs, or local environments and features a control plane designed for managing tools, users, permissions, and observability. This comprehensive management system ensures that developers can maintain oversight and control while leveraging the power of AI to automate various tasks effectively.

MCPTotal is a robust, enterprise-level solution that facilitates the management, hosting, and governance of MCP (Model Context Protocol) servers and AI-tool integrations within a secure, audit-friendly framework, rather than allowing them to operate haphazardly on developers' local machines. The platform features a “Hub,” which serves as a centralized, sandboxed runtime space where MCP servers are securely containerized, fortified, and thoroughly vetted for potential vulnerabilities. Additionally, it includes an integrated “MCP Gateway” that functions as an AI-focused firewall, capable of real-time inspection of MCP traffic, enforcing security policies, tracking all tool interactions and data movements, and mitigating typical threats like data breaches, prompt-injection attempts, and improper credential use. Security measures are further enhanced through the secure storage of all API keys, environment variables, and credentials in an encrypted vault, effectively preventing credential sprawl and the risks associated with storing sensitive information in plaintext on personal devices. Furthermore, MCPTotal empowers organizations with discovery and governance capabilities, allowing security teams to conduct scans on both desktop and cloud environments to identify the active use of MCP servers, thus ensuring comprehensive oversight and control. Overall, this platform represents a significant advancement in the management of AI resources, promoting both security and efficiency within enterprises.
