## Kiro

Kiro is a spec-driven coding platform from AWS that reframes AI assistance around intent rather than autocompletion. You describe what the software should do and supply context, and Kiro turns that into specifications that guide an agent through planning, implementation, testing, and review. Because requirements and design decisions are written down first, agents can check their results against what you actually asked for, and the platform deliberately enforces quality at each step so agents cannot silently skip a failing test.

The product spans multiple surfaces. Kiro IDE is the familiar desktop experience, the CLI installs with a single command and can run headless in CI/CD, and cloud sessions move long-running tasks off your laptop with parallel agents that keep working after you close the lid. Kiro Crew adds persistent agents that watch your backlog, codebase, or CI pipeline, triage incoming work, spawn specialized bots, and bring results back for your approval. It also meets you where work happens, whether that is Slack, Microsoft Teams, GitHub or GitLab issues and pull requests, or scheduled automation.

Underpinning this is persistent memory across sessions, shared team knowledge, and reusable steering so corrections do not need repeating. Workflows break large tasks into checked steps, property-based tests validate behavior across hundreds of cases, and adversarial review agents scrutinize diffs before a human approves. Kiro supports Claude, GPT, and open-weight models such as DeepSeek and Qwen, with an Auto mode that routes each task to a suitable model, and it is built on open standards including ACP, AGENTS.md, Skills, MCP, and Open VSX extensions.

**Pricing & Plans:** Kiro follows a freemium model with free usage to get started and paid tiers that add higher usage limits and credits for individual developers and teams. Enterprises can contact AWS for governance, SSO, compliance, and predictable pricing arrangements.

- **Specs that verify intent:** You describe intent and context first; Kiro captures requirements and design as specifications, then verifies the finished implementation against them.
- **Persistent agents and Crew:** Kiro Crew watches your backlog, codebase, or CI, triages new work, delegates to specialized bots, and returns results for your review.
- **Workflows and adversarial review:** Long tasks split into checked steps so agents cannot shortcut a failed test, and review agents inspect diffs before a human approves a merge.
- **Runs where you work:** Use the IDE, mobile, or web, run headless in CI/CD with the CLI, or trigger Kiro from Slack, Microsoft Teams, GitHub, and GitLab.
- **Open standards and model choice:** Supports ACP, AGENTS.md, Skills, MCP, and Open VSX extensions, with Claude, GPT, and open-weight models via Auto routing.

**Strengths:** Spec-driven workflow ties generated code back to written requirements and design; Multiple surfaces including IDE, CLI, web, mobile, and cloud sessions; Persistent memory and shared steering reduce repeated corrections across sessions; Built and run by AWS with enterprise governance, SSO, and compliance backing

**Limitations:** Spec-first discipline adds upfront effort compared with prompting a chat assistant; Heavier sessions consume credits, so heavy usage can push you onto paid tiers; Tightest experience is with AWS and its surrounding ecosystem, which may not suit every stack

## Orca

Orca positions itself as an "agent IDE" rather than a classic code editor. The core idea is that IDEs were designed around a single human editor, while AI-era workflows revolve around many agents working at the same time. Orca therefore organises work into projects, workspaces and worktrees: each task gets an isolated environment, and any agent CLI can be pointed at it.

The app bundles the pieces developers normally stitch together by hand — chat or terminal interfaces, a built-in browser with a design-inspection mode, split panes for diffs and files, a notes/editor surface and Git integration. A command-line interface mirrors the GUI, so agents themselves can create worktrees, start workers, drive the browser and schedule automations through Orca's own CLI.

Orca is cross-platform (macOS, Windows, Linux) with companion iOS and Android apps that notify you when an agent needs input so you can reply from your phone. It is distributed as free open-source software, and the project also offers a documented enterprise track and a plugin system for extending the environment.

**Pricing & Plans:** Orca is free and open source; the download and core product require no payment. A separate Enterprise offering is available, priced by contacting the team. The site does not publish a public price list for enterprise plans.

- **Parallel worktrees:** Each agent gets its own isolated Git worktree, so multiple agents can edit, test and build concurrently without conflicts.
- **Bring your own agent CLI:** Works with Claude Code, Codex, Gemini, Cursor CLI, OpenCode, Copilot, Cline and many other command-line agents using subscriptions you already have.
- **Integrated browser and design mode:** A built-in browser lets you click any element to copy its HTML, styles and selector, or screenshot a page and drop that context straight into an agent prompt.
- **Terminal, diffs and split panes:** Review AI output, run commands and arrange terminals, browsers, files and diffs in panes shaped to the task at hand.
- **CLI, plugins and mobile companion:** Orca's own CLI lets agents automate worktrees and workers, a plugin system extends the app, and iOS/Android apps keep you in the loop remotely.

**Strengths:** Free and open source, with no licence cost for the core product; Genuinely parallel workflow thanks to per-task Git worktrees; Vendor-neutral: works with many agent CLIs instead of locking you to one; Cross-platform with iOS and Android companion apps and an extensible plugin system

**Limitations:** Not a traditional IDE, so developers wanting a full editor experience may need a second tool; Newer product with fast-moving releases, which can mean occasional rough edges; Enterprise pricing is only available on request, so costs are not transparent up front
