superpowers is an excellent, free skills framework — it brings test-driven discipline and a library of composable skills to claude code in the terminal. defract is a different layer: a macos app that runs your whole build as a gated lifecycle — story, design, architecture, review, release — with a visual design stage, parallel git-worktree orchestration, and agent-reviewed merges. one adds skills to the cli. the other is the process around it.
they fight the same enemy. superpowers and defract are both answers to the same problem: unstructured agents that drift, skip steps and ship slop. superpowers solves it with skills and test-driven discipline you install into the claude code cli. defract solves it as an integrated app. if you live in the terminal and like composing your own stack, superpowers is a great choice — and it's free and open-source.
the common pattern is to combine several frameworks — superpowers for execution, one for context, one for governance — and maintain the seams yourself. defract is that structure, built in.
scope → design → architecture → implementation → review → release, in one ui, with the gates and the orchestration already wired together. you download and open it; there's no framework to install, compose, update, or keep in sync as each one changes.
skills frameworks work in text — prompts, tests, rules. defract runs a design stage most tools skip entirely.
a design agent renders html mockups live so you see the ui before any code is written. versions you can compare, annotations you can click.
types, lint and tests gate every merge, plus review agents for architecture, security and ux. you sign off on intent and shape, not an 800-line diff.
in the cli you run and track parallel work yourself. defract isolates every story in its own git worktree and remembers your codebase across builds.
multiple stories run at once, each in its own worktree, so parallel agents never collide on main — and a memory-consolidator agent feeds your decisions and corrections into the next build, so the tool gets sharper at building your product the more it runs. no scripts, no bookkeeping.
| defract | superpowers | |
|---|---|---|
| what it is | a lifecycle orchestrator app on top of claude code | a skills framework you install into the claude code cli |
| form | a macos app that runs claude code for you | skills, prompts and rules added to the cli |
| structure | guided pipeline: scope → design → architecture → implementation → review → release | test-driven discipline and a composable skills library |
| visual design stage | a visual gate — agent-authored html mockups rendered live, with versions and click-to-annotate | none — work happens in text |
| parallelism | git-worktree isolation, parallel by default, managed for you | you run and track parallel sessions yourself |
| code review | agents review agents (types · lint · tests · architecture · security · ux); merge gated on sign-off | tests you author and drive via skills |
| memory / context | persistent memory of codebase, decisions, conventions — compounds over time | context engineering via skills; no built-in cross-run memory |
| setup | download, open | install and compose skills; combine frameworks as needed |
| platform | macos (windows · linux in v1) | cross-platform — anywhere the cli runs |
| cost | free — bring your own claude | free · open-source |
| availability | open beta — download now | available now |
we'll be straight: superpowers is free, open-source and cross-platform — it runs anywhere the claude code cli runs, including linux and windows today. it has a large, composable skills library and a strong test-driven-development backbone, and if you love working in the terminal and assembling your own setup, it meets you exactly there.
defract is in open beta — claude code on macos for now, with windows landing next. the bet we're asking you to make is on the integrated lifecycle: the whole path from story to shipped, with a visual design stage and parallel orchestration built in, instead of a stack you compose and maintain. see how we think about running parallel claude code agents, or compare with claude code on its own.
download the open beta. if you've been stacking skills frameworks to force process onto the cli, we'd love your eyes on it.
