Leia
What is Leia?
Leia was a web app that built business websites through voice and text prompts, marketed with the tagline to create a digital presence in 90 seconds. Users could publish sites from mobile or browser editors without coding, and Braidio acquired Leia in September 2021 to fold its builder into the WorkStream customer engagement platform.
The heyleia.com homepage no longer offers that builder flow. It now displays unrelated online casino affiliate reviews, while legacy subpages such as the blog and Growth Club upgrade screen still carry Leia branding from the earlier product era.
This listing marks Leia as discontinued at heyleia.com. Small business owners who relied on the free builder should treat the domain as repurposed rather than an active website creation service.

What is cto.new (formerly Backengine)?
cto.new lets you build apps, autonomous agent teams, and full AI businesses on frontier models from Anthropic, OpenAI, Gemini, Mistral, Grok, and DeepSeek without supplying a credit card or personal API keys. You spin up web and mobile apps, multi-agent teams, and full AI businesses from a single chat workspace inside hosted cloud sandboxes.
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. Web app projects ship with Convex as the default backend, giving new builds database, auth, file storage, and serverless functions without separate setup.
Where most AI coding tools sell subscriptions and cap model usage, cto.new keeps a free forever tier that is ad-supported with daily limits that reset each day. Its marketplace sells ready-made multi-agent businesses you deploy in one click, closer to hiring a prefab team than prompting a single chatbot.
The free tier covers frontier models, unlimited AI businesses, web and mobile apps, CTOClaw agents, and MCP integrations. Premium starts at $20 per month for higher usage, pro agent features, and premium model access.
