What does each plugin do for a founder?

Superpowers: build without the mess

Claude Code on its own jumps straight to code. Superpowers makes it brainstorm, write a design, plan the work, then test as it goes. You get fewer half-finished features. It is the most starred plugin here: 303.5k stars on GitHub.

Marketing Skills: sell what you built

Skills for page copy, signup flows, SEO, cold email, pricing and launches. Claude applies the right one when you ask for marketing work. It starts from one product-marketing file that the other skills read first, so describe your product there once.

feature-dev and code-review: a second pair of eyes

Both come from Anthropic's official plugin directory. feature-dev walks one feature through seven phases. code-review checks a pull request with several agents and filters out weak findings. Useful when you have no co-founder to review your work.

frontend-design: pages that look designed

Also from Anthropic. It turns on by itself for front-end work and steers Claude toward bolder layout and type.

Supabase and PostHog: your data, in the chat

Both connect Claude to your account in that service. You sign in once in the browser. Then you can ask "how many people signed up this week?" or "add a column for the plan name" in plain words. Both are listed in Anthropic's official plugin directory.

Remotion skills: a launch video in code

Remotion makes videos with React code. The skills teach Claude how to use it well. Check the license if your company has more than 3 employees.

Bootstrapped OS: the whole business

Note: I built this one. I run AgentaOS, a payments company, alone with it. It covers the path from idea to a product that takes payments, then the daily work of getting customers. It is also the newest here: 9 stars on GitHub when I checked. It is built on several of the plugins above, and it works alongside them.

How did I pick these?

1. Useful for running a business, not only for writing code.
2. Public and free to install, with the source on GitHub or an official docs page.
3. Made by the team behind the tool, or widely used. GitHub stars on 22 October 2026: Superpowers 303.5k, Marketing Skills 56k, Remotion skills 5.5k, Bootstrapped OS 9. Anthropic's official directory, which lists feature-dev, code-review, frontend-design, Supabase and PostHog, has 43.8k.

The order follows what most founders need first. It is not a score. Tell me if I got yours wrong and I will fix it.

Which one should you install first?

Still building? Superpowers. Product works but nobody buys? Marketing Skills. Live with users? PostHog, so you see what they do. Want one setup for the whole business? Try Bootstrapped OS, and remember who wrote this page.

Questions founders ask

Are Claude Code plugins free?

All nine here are free to install. You still need a Claude plan that runs Claude Code. Plugins that connect to a service, such as Supabase or PostHog, use that service's own plan, and both start free.

How do I install a Claude Code plugin?

Inside Claude Code, type /plugin install with the plugin's name, or browse with /plugin. Plugins outside Anthropic's directory need one extra line first: /plugin marketplace add with the GitHub owner and repo name.

Do I need to be a developer to use Claude Code plugins?

No, but you need to be comfortable typing commands in a terminal. Marketing Skills and Bootstrapped OS are written for marketing and business work, not code.

Which Claude Code plugin should a founder install first?

The one for the step you are stuck on. Building: Superpowers. Selling: Marketing Skills. Measuring: PostHog. Install one, use it for a week, then add the next.
