Superpowers is an open-source framework by Jesse Vincent (obra) that imposes a disciplined 7-phase software development workflow on AI coding agents: brainstorm → git worktrees → plan → subagent development → test-driven development → code review → branch completion. The core insight is that agents like Claude Code and Codex will skip tests and architectural planning if not explicitly constrained — Superpowers enforces these phases via structured prompts and hooks that agents cannot easily bypass. The framework works across Claude Code, Cursor, Codex, Gemini CLI, and GitHub Copilot CLI. Each phase has defined inputs, outputs, and acceptance criteria, and agents use git worktrees to isolate branches so failed experiments don't contaminate main. The TDD phase is mandatory: tests must be written and passing before any implementation code is reviewed. V5.0.7, released March 31, fixed Node.js 22+ compatibility and added Codex App support. As of April 8, 2026, Superpowers is the #1 trending repository on GitHub with 1,926 new stars today, bringing its total to 141k. It's one of the fastest-growing developer tools of 2026 — growing from ~27k stars in January to 141k in under three months.

The Vercel AI SDK provides React hooks, streaming utilities, and provider abstractions for building AI-powered UIs. Works with any LLM provider. The standard for AI web apps.
Reviewer scorecard
“141k stars doesn't lie — this fills a real gap. Claude Code is brilliant at generating code and terrible at knowing when to stop and write a test. Superpowers adds the engineering discipline that solo devs usually skip under deadline pressure. The git worktree isolation is a particularly smart detail that prevents agent experiments from trashing your main branch.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“The 7-phase workflow adds significant overhead for simple tasks — if you're just fixing a bug or adding a small feature, going through brainstorm → worktrees → subagents → TDD → review is overkill and will frustrate developers who just want to ship. The star count reflects GitHub trending momentum as much as actual adoption.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“What Superpowers is really doing is encoding decades of software engineering best practices into a prompt-based specification that AI agents can follow. As agents become more autonomous, frameworks like this become the guardrails between 'AI that writes code' and 'AI that ships reliable software.' The TDD enforcement alone could prevent enormous amounts of AI-generated technical debt.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
“As someone who uses AI coding tools to build side projects, the biggest pain point is agents generating code that works once and breaks mysteriously later. Superpowers' mandatory test phase would have saved me countless debugging sessions. It's more structure than I'd set up myself, which is exactly the point.”
