Atoms

What is Atoms?
Describe a product in chat and Atoms assigns a team of coding agents to research, architect, build, test, and deploy a full-stack app with login, database, Stripe payments, and hosting. Named agents cover product management, engineering, SEO, Google Ads, and data analysis in one workflow. The platform evolved from the MetaGPT open-source multi-agent framework and reports 1M+ builders across 170+ countries.
Most vibe-coding tools stop at a frontend mockup. Atoms assigns named agents (Product Manager Emma, Engineer Alex, SEO Specialist Sarah, Ads Specialist Adrian, and others) to cover research through customer acquisition in one workflow. Race Mode runs prompts across multiple models for higher accuracy on Max plans, and you can export code or sync to GitHub when you outgrow the hosted builder.
Solo founders, indie hackers, and non-technical teams use Atoms to ship SaaS subscriptions, internal dashboards, portfolios, and e-commerce pages without hiring a dev shop. One-click publishing handles hosting, while built-in SEO and Google Ads agents target paying customers from day one.
Copilot Chat

What is Copilot Chat?
Copilot Chat is a test-driven code generation tool that helps developers produce JavaScript functions from input-output test cases. You define inputs, expected outputs, and an optional requirement description, then the tool uses an LLM to generate code and validate it against your tests.
If a test fails, Copilot Chat iteratively refines the generated code with the model until every case passes. The site includes worked examples for tasks like parsing GitHub URLs, parsing CSS color strings, and capitalizing words in a string.
The workflow is inspired by test-driven development and flow-engineering ideas similar to TypeChat and AlphaCodium, focusing on repeatable validation instead of one-shot prompt output.
