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.
Just Prompts
What is Just Prompts?
Just Prompts is a browser-based prompt workshop that applies Additive Prompting to whatever you type in. You paste your OpenAI API key once, enter a starting idea in the text field, and hit Prompt to get an expanded version back as formatted markdown in the output panel.
Most prompt playgrounds give you a blank chat box. Just Prompts is built around one specific technique from @nickfloats called Additive Prompting, which layers structure onto a rough idea instead of leaving you to guess what to add next. The whole interface is a single input, one submit button, and a rendered answer area.
Developers and writers who already have an OpenAI key and want a fast way to stretch a half-formed prompt into something more complete will find it useful. There is no account, no pricing page, and no extra features beyond key storage in a browser cookie and markdown output.
