Backengine vs Embolden

cto.new is a free platform for building apps, agents, and startups on frontier AI models from Anthropic, OpenAI, and others. You can sign up without a credit card or your own API keys, then spin up web and mobile apps, multi-agent teams, and full AI businesses from a single workspace.

The product centers on agent teams that can browse the web, send email, schedule tasks, and connect to external tools through MCP servers. Integrations listed on the site include Linear, Sentry, Vercel, and Notion, with support for adding any MCP-compatible server.

A marketplace lets you hire pre-built AI teams (engineering, marketing, content, sales, and more) or list your own agent business for others to buy. Use-case guides cover AI customer support, marketing, and receptionist workflows built around a team lead plus specialist agents.

The free tier is ad-supported with daily limits that reset each day. Premium starts at $20 per month for higher usage, pro agent features, and access to premium models.
