Vybe
Vybe is an AI agent platform where autonomous agents build, connect, and operate business applications across your existing tech stack. Instead of forcing teams to adopt rigid SaaS tools or hire engineers for every workflow, Vybe lets operators deploy AI agents that create custom apps, integrate with 3,000+ services (Salesforce, HubSpot, Slack, Google Workspace, Stripe, Linear, GitHub, Intercom, QuickBooks, and more), and run ongoing business processes — customer success triage, sales follow-ups, content production, SEO reporting, CRM updates, internal dashboards, and custom portals. Use cases span sales, marketing, customer support, operations, finance, and recruiting. Built for startup founders, mid-market operators, and enterprise teams who want to automate work without the engineering backlog. Backed by First Round Capital.

Replit includes Infinite Canvas for visually exploring and tweaking designs before applying them directly to an app. Parallel Agents let multiple tasks run at once, helping teams build authentication, databases, design, and other features faster. Built-in infrastructure includes authentication, database, hosting, monitoring, AI integrations, and connections to services such as OpenAI, Stripe, and Google Workspace.

Agent 3
Replit Agent 3 is the most autonomous, AI-powered builder yet for creating production-ready applications entirely through natural-language prompts. You describe the app or website idea, and Agent automatically handles everything: setting up the full-stack environment, designing interfaces, configuring databases, managing dependencies, and integrating authentication or third-party services like Stripe or OpenAI. It offers two development modes: a visual-first “Start with a design” option that generates a clickable prototype in just minutes before enabling full functionality, or a “Build the full app” mode that constructs a functioning application, including frontend, backend, and integrations, in around 10 minutes. Agent 3 also self-tests within a browser workflow, identifying bugs, fixing them, and rerunning tests in a continuous reflection loop that is up to 3x faster and 10x more cost-efficient than traditional testing models.
