Open Source Tools

Great software starts with great tools. We build ours from scratch, use them daily, and share them with you.

Our Clojure kit — a family of modular libraries for building web apps. Apron for core utilities, Bucket for persistence, Wire for frontend, and Scaffold for builds. Jig is a CLI tool that spins up a new project faster than ever.

cleancoders/agent-plugins

A family of Claude Code plugins for AI agent workflows — kanban-dashboard for live team visibility, clojure for Clojure-specific craftsmanship, and clojure-security for Clojure-specific security review as the agent writes code.

C3Kit

Modular Clojure component toolkit

C3Kit is a family of modular Clojure libraries that form the foundation for every application we build. Each library handles a different concern and can be pulled independently as a dependency.

Apron provides the necessities almost any Clojure app needs—schema, time, logging, and more. Bucket gives you one identical API for data, whether it lives in Datomic on the server or in-memory on the client. Wire is a toolset for rich-client web apps, spanning Clojure on the server and ClojureScript on the client. Scaffold handles build tooling—ClojureScript compilation and Garden CSS transpiling with auto-recompile.

Jig is a CLI tool for starting new projects faster than ever. Simply select the features you're going to need in your project, and Jig will build everything you need to get coding a full-stack application with c3kit.

The Libraries

c3kit/apron

Core Utilities

Necessities almost any Clojure app needs — schema validation, time helpers, logging, entity indexing, cursors, and edn/transit/CSV.

ClojureFoundation

c3kit/bucket

Persistence

Identical API for data on the server (Datomic) and the client (in-memory). Plus migrations, hashids, and background tasks.

ClojureDatomic

c3kit/wire

Rich-Client Toolkit

Toolset for rich-client web apps — Ajax, WebSockets, flash messaging, asset fingerprinting, drag-and-drop, and dev reload.

ClojureScriptFull-Stack

c3kit/scaffold

Build Tooling

Compiles ClojureScript (with watch mode) and transpiles Garden CSS to stylesheets with auto-recompile.

ClojureDev Tools

c3kit/jig

Project Bootstrapping

A CLI that bootstraps entire projects from templates. The quickest way to get started using c3kit. Select features and get coding faster than ever.

Cleancoders Agent Plugins

Claude Code plugins for AI agent workflows

A marketplace of Claude Code plugins built for AI agent workflows. Install once and share the same discipline, dashboards, and skills across every project your team touches.

kanban-dashboard is a live MCP server and browser dashboard for agent teams — task cards, dependencies, and file diffs update in real-time so you can see parallel work at a glance.
clojure bundles specialist skills, hooks, and configurations for Clojure and ClojureScript work, including writing and testing migrations, Reagent patterns, c3kit, Speclj testing, and formatting with cljfmt.
clojure-security makes sure that your coding agent is SSDLC/DevSecOps aware with linting, SAST, and dependency scanning. It provides skills, hooks, and configurations for clj-kondo, clj-holmes, clj-watson, and gitleaks.
