One Claude Code in one terminal is a bottleneck. Three free open-source tools turn it into an assembly line: parallel agents on a kanban board, spec discipline, and ready-made configs in a single command ⚡
What it is and who it's for
This isn't one product but a bundle of three independent open-source projects around Claude Code (most of them work with Codex, Gemini CLI and Cursor too):
- Vibe-Kanban (BloopAI/vibe-kanban, ★27.4k) — a local kanban board for orchestrating coding agents: you plan tasks as cards, each one runs in its own isolated git worktree, and you review diffs right in the interface.
- Get Shit Done (GSD) — a system of meta-prompting, context engineering and spec-driven development by TÂCHES: it treats "context rot", the agent's degradation as the context window fills up. The original repo collected ★64.8k; active development continues as GSD Core.
- Claude Code Templates (davila7/claude-code-templates, ★29.4k) — a CLI and the aitmpl.com catalog with 100+ ready agents, commands, hooks, settings and MCPs: don't assemble a config from scratch, install something proven in one command.
Who it's for: vibe coders and developers on Claude Code who feel boxed in by "a single chat" — they want to parallelize tasks, keep quality up on long features and stop configuring their environment by hand.
Key features
- Vibe-Kanban: parallel agents without conflicts — every task in its own git worktree; diff review with highlighting before merge; support for Claude Code, Codex, Gemini CLI, Copilot, Cursor, Amp and others; works as both an MCP client and an MCP server — the agents move the cards themselves.
- GSD: a repeatable Discuss → Plan → Execute → Verify → Ship cycle; heavy research and planning get handed to subagents with fresh context; the
/gsd-new-project(new project) and/gsd-onboard(existing code) commands; besides Claude Code it supports OpenCode, Codex, Copilot, Cursor and Windsurf. - Claude Code Templates: interactive installation of agents/commands/hooks/MCPs; the aitmpl.com web catalog; plus real-time Claude Code session analytics and an installation health check.
How to start in 5 minutes
- Kanban for agents:
npx vibe-kanban
A web interface opens — point it at your repo, create a task, assign an agent. 2. The spec workflow — inside your project folder:
npx @opengsd/gsd-core@latest
Then run /gsd-new-project or /gsd-onboard in Claude Code.
3. Ready-made configs:
npx claude-code-templates@latest
Pick components interactively or find what you need at aitmpl.com.
When to take it, when not to
✅ Take it if you run several tasks in parallel and you're tired of juggling branches and terminals by hand. ✅ Take it if long features fall apart toward the end of the context window — the GSD spec workflow holds quality over distance. ❌ Don't take GSD if your tasks are 15-30 minutes long — Claude Code's built-in plan mode is enough, and specs for small stuff are overhead. ❌ Don't take Vibe-Kanban → "Cursor" or "Cline" is better if you live in an IDE and one task at a time is plenty.
The honest price
All three tools are free and open source: Vibe-Kanban is Apache-2.0, GSD and Claude Code Templates are MIT. No card needed, everything runs locally, your code never leaves the machine. But Claude Code itself won't become free: you need a Claude subscription (Pro/Max) or an API key, and parallel agents in Vibe-Kanban chew through your limits many times faster than one.

Gotchas
- Bloop AI shut down (announced 10.04.2026): Vibe-Kanban's cloud services are being switched off and the project is passing to the community. Local mode works, but further development depends on contributors — official announcement.
- The original GSD repo (gsd-build/get-shit-done) is archived — the current version lives only in open-gsd/gsd-core. Older guides online install the outdated package.
- GSD Core is noticeably younger than the original (v1.6.1 as of July 2026): docs and commands are still migrating, so check the README.
- aitmpl.com components are written by the community: agents and hooks execute code on your machine — read what you're installing.
- Orchestration doesn't cancel review: three agents in parallel means three diffs to check, not zero.

"I'm running the project
in Claude Code, with Vibe-Kanban and GSD on top. Break the feature into 3-5 independent kanban tasks: each with a goal, acceptance criteria, the files it touches and a note on whether it can run in parallel without conflicts. Take the biggest task through the GSD cycle (Plan → Execute → Verify) and suggest which ready-made components from aitmpl.com (agents, commands, MCPs) would speed up this particular stack."
