Kiro Alternatives: 9 Options Grouped by What You Want Instead

The best Kiro alternative depends on which part of Kiro you want to keep. Kiro is AWS's agentic coding tool, and its signature move is spec-driven development: before any code changes, it writes a requirements file, a design file, and a task list, then works through the tasks. Some people love that structure and want it somewhere else. Others want to drop it entirely.

So this guide groups the options by what you're actually after:

• Keep the specs, change the tool → GitHub Spec Kit or Claude Code's plan mode
• Keep an AI editor, lose the ceremony → Cursor, Google Antigravity, or Devin Desktop
• Work in the terminal → Claude Code or Codex CLI
• Stay on AWS → Claude Code on Amazon Bedrock (not Amazon Q Developer, which is winding down)
• Go open source and bring your own model → Cline or OpenCode

If you're only weighing Kiro against one editor, our Kiro vs Cursor comparison goes deeper on that pair. This post covers the wider field.

Quick comparison

What Kiro does that you'd be replacing

Before you switch, check what you'd give up. Kiro has changed a lot in 2026.

Specs. Kiro's spec workflow produces three files: requirements.md (or bugfix.md for a Bugfix Spec), design.md, and tasks.md. Feature Specs come in Requirements-First and Design-First variants. Quick Spec generates all three "in one pass without approval gates" when you already know what you want.

Steering and hooks. Steering files tell the agent how your project works and carry across Kiro's surfaces. Hooks run background jobs, such as tests or doc updates, when a trigger fires.

More surfaces than people assume. Kiro now has an IDE, a CLI, a web app that runs tasks in cloud sandboxes, and Crew, which its FAQ describes as a free, open-source workspace that runs on your machine. Per the Kiro changelog, CLI 3.0.0 shipped on November 3, 2026 as a single standalone binary, with an /autonomous on mode that runs tasks without per-command approval, sandboxing on.

Credits. Kiro bills in credits. Its pricing page says "A credit is a unit of work in response to user prompts," and premium models use more of them. Each plan has a monthly allowance that doesn't roll over.

If the reason you're leaving is "Kiro has no CLI" or "Kiro only works in the editor," that's no longer true. The more common reasons are the spec overhead on small tasks, the credit meter, and wanting a different editor or model setup.

If you want spec-driven development without Kiro

You like writing the spec first. You just want it in a tool you already use.

GitHub Spec Kit

GitHub Spec Kit is the closest match to Kiro's method that isn't Kiro. It's an MIT-licensed toolkit that adds spec-driven commands to the AI coding agent you already run. You install a CLI called specify, then run commands in your agent's chat:

1. /speckit-constitution sets the project's ground rules
2. /speckit-specify writes the spec
3. /speckit-plan turns it into a technical plan
4. /speckit-tasks breaks the plan into tasks
5. /speckit-implement builds them

The steps map closely onto Kiro's requirements → design → tasks flow, and the files live in your repo. The difference: Spec Kit is a process layer, not an editor. Bug-fixing and idea-assessment commands come as separate extensions you install.

Pick it if you want Kiro's discipline but your team is standardized on another agent.

Claude Code plan mode

Claude Code has a lighter version of the same idea. In plan mode, Anthropic's workflow docs say Claude "reads files and proposes a plan but makes no edits until you approve." You enter it with claude --permission-mode plan, or by pressing Shift+Tab until the status bar shows plan mode is on.

You get one plan instead of three linked files, and no live task tracking. For many teams that's the point: it gives you the "think before you code" step without the paperwork on every change. Our Claude Code plan mode guide walks through the approval flow.

If you want an AI IDE without the spec overhead

You want to stay in an editor. You just don't want every task to start with a requirements doc.

Cursor is the obvious one. It starts you in agent chat and tab completion, and its Plan Mode adds structure only when you switch into it. Like Kiro, it's built on the VS Code codebase and reads AGENTS.md. Cursor has been part of SpaceX since August 2026.

Google Antigravity is now a family of surfaces: a desktop app described as a "command center to manage multiple local agents in parallel," a full agentic IDE, a CLI, a Python SDK, and IDE extensions. Its agents produce artifacts you can review as they work. Our Google Antigravity vs Cursor breakdown compares it with Cursor in detail.

Devin Desktop is what Windsurf is called now. Cognition says "Devin Desktop is the new name for Windsurf," and that plans, extensions, and settings carry over. It keeps the full IDE and adds an agent command center with Spaces, a Kanban view, and multi-agent management, locally or in Devin Cloud.

If you want a terminal agent instead

Kiro has a CLI now, but some developers want a tool that was terminal-first from the start.

Claude Code is the most common pick. It runs in your terminal, reads your repo, edits files, runs commands, and can be scripted for CI. Plan mode (above) covers the planning step.

Codex CLI is OpenAI's open-source agent that "runs locally on your computer." It's Apache-2.0 licensed. You sign in with a ChatGPT account, which its README recommends for Plus, Pro, Business, Edu, and Enterprise plans, or with an API key.

The practical split: if you already pay for a ChatGPT plan, Codex CLI uses it. If your team is on Claude, Claude Code is the natural fit. Both sit in the same terminal you already use.

If you want to stay on AWS

This is where many Kiro searches start, so here's the current state.

Amazon Q Developer is not a long-term alternative. AWS's own end-of-support announcement says Q Developer's IDE plugins and paid subscriptions "will reach end of support on April 30, 2027," and that new signups stopped on May 15, 2026. AWS points those users to Kiro. Q Developer in the AWS Management Console and other first-party AWS experiences is not affected. In other words, Q Developer is moving people toward Kiro, not away from it.

If you want AWS billing and governance but not Kiro, a cleaner route is running a terminal agent through Amazon Bedrock. Claude Code supports Amazon Bedrock as a model provider, so usage runs through your AWS account. You trade Kiro's specs and hooks for Claude Code's plan mode, hooks, and subagents.

If you want open source and your own model keys

Kiro picks the models and meters them in credits. If you'd rather pay your model provider directly, look here.

Cline calls itself "One open source agent runtime." It runs as a desktop app, as an extension in VS Code, Cursor, Windsurf (now Devin Desktop), or JetBrains, as a CLI, and as an SDK. Its Plan mode agrees a strategy before any change, and Act mode carries it out with per-step approval or auto-approve. You bring your own API key, endpoint, or local model.

OpenCode is "The open source AI coding agent," MIT-licensed, with a terminal interface, a desktop app, and an IDE extension. It supports 75+ model providers, including local models, and works with some existing subscriptions.

Both cost you more setup than Kiro. In return, you control which model runs and what you pay for it.

Which Kiro alternative should you pick?

• You like specs but not Kiro's editor → GitHub Spec Kit on top of your current agent
• You want planning, but lighter → Claude Code plan mode or Cursor Plan Mode
• You want to manage several agents at once → Google Antigravity or Devin Desktop
• You live in the terminal → Claude Code or Codex CLI
• Your company runs on AWS → Claude Code through Amazon Bedrock; skip Q Developer for new work
• You want to own model choice and cost → Cline or OpenCode

Key points to take away:

• Kiro's real differentiator is the spec workflow. Decide whether you're keeping it or dropping it before you compare tools
• Spec Kit is the most direct way to keep Kiro-style specs in another agent
• Amazon Q Developer is being retired in favor of Kiro, so it isn't an exit route
• Every tool here has some planning step now. The difference is how much structure it forces on you

When the setup is the hard part

Every tool above assumes you have a repo and want help changing it. A lot of people get stuck earlier: they saw an AI agent or workflow someone built and never got it running. Taku is built for that gap. You mirror a working AI setup into a desktop workspace and run it, without reproducing someone else's environment first. Taku is in Beta, and the Mac app is available now.

FAQ

What is the best alternative to Kiro?

It depends on why you're leaving. For spec-driven development in another agent, GitHub Spec Kit is the closest match. For a fast AI editor, Cursor. For a terminal agent, Claude Code or Codex CLI. For open source with your own model keys, Cline or OpenCode.

Is there a free Kiro alternative?

Several are open source: Spec Kit (MIT), Codex CLI (Apache-2.0), OpenCode (MIT), and Cline. The software costs nothing, but you still pay for the model, either through an API key or an existing subscription.

Is Amazon Q Developer replacing Kiro?

The reverse. AWS says Q Developer's IDE plugins and paid subscriptions reach end of support on April 30, 2027, new signups closed on May 15, 2026, and AWS points users to Kiro. Q Developer in the AWS console continues.

Does any other tool do spec-driven development like Kiro?

Yes. GitHub Spec Kit adds constitution, specify, plan, tasks, and implement commands to supported agents. Claude Code's plan mode and Cursor's Plan Mode give you a single plan to approve, which is lighter than Kiro's three files.

Is Kiro open source?

Kiro's FAQ describes Kiro Crew, its local workspace, as free and open source, and you can install it from GitHub. If you want an open-source coding agent that runs on your own model keys, look at Cline, OpenCode, or Codex CLI.

Can I keep my VS Code setup if I leave Kiro?

Mostly. Kiro, Cursor, and Devin Desktop are all built on the VS Code codebase, and Cline runs as a VS Code extension. Terminal agents like Claude Code and Codex CLI work alongside whatever editor you already use.
