## Ara (Reason Machines)

Ara began as a self-driving AI IDE and has since rebranded to Reason Machines. The product is built around a single idea: you should not have to choose between competing coding agents. Reason runs on a shared network that lets your teammates and multiple agents — Claude Code, Codex, Cursor and others — work side by side on the same repository, handing off tasks and merging results.

The platform offers three main surfaces. You can use Reason on the web, download a desktop app where agents are given names and teams, or call it programmatically through a REST API. The API lets you start a session from a script, CI job, or your own product, then poll and stream the result, which makes it practical to embed autonomous coding into existing pipelines.

Reason positions itself on cost efficiency and effectiveness, advertising frontier-class benchmark results at a low price point, backed by Y Combinator. It also integrates with collaboration tools such as Slack, where you can mention the agent in a thread and receive a pull request or deck when the work completes.

**Pricing & Plans:** Ara/Reason advertises a free, open-source engine and positions itself as a low-cost option for maximizing AI usage. Specific seat and usage pricing is not published on the marketing page, so contact the vendor or visit the site for current plans.

- **Multi-agent orchestration:** Run Claude Code, Codex, Cursor, and Reason agents on the same repository without conflicts, so each tool handles what it does best.
- **Programmatic sessions via API:** Start an agent session from a script, CI job, or your own product, then poll or stream the result through a REST endpoint.
- **Desktop app with named teammates:** Give each Reason agent a name and team, and watch it work in a shared workspace alongside your human teammates.
- **Slack integration:** Mention Reason in a Slack thread and get back a pull request, presentation, or answer once the task is finished.
- **Benchmark-focused performance:** Optimized for strong results on coding benchmarks, marketed as a cheaper alternative to other frontier agents.

**Strengths:** Coordinates multiple coding agents instead of forcing you to pick one; Offers web, desktop, and API access for different workflows; Free, open-source engine with a cost-focused positioning; Backed by Y Combinator with visible enterprise adopters

**Limitations:** Recently rebranded, so documentation and naming are still shifting; Concrete pricing details are not clearly published on the marketing site; Feature set overlaps with the agents it orchestrates, which can be confusing to scope

## 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
