## 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

## crystl

crystl rethinks the terminal for the era of agentic coding. Every project you open is treated as a "gem," and every session inside it is a "shard." Run several agents in the same project at once and each shard gets its own git worktree and branch, so parallel sessions stay isolated instead of stepping on each other's files. Off-screen shards throttle to near-zero render work, which means scaling from two agents to a dozen stays light on a Mac.

Coordination is the core of the product. There is an orchestrator mode that monitors worker agents and can read their terminals, a "quest" mode that convenes role-played agents in a shared chat to divide work and debate approaches, and hero shards that summon a single specialist with its own agent, model and persona. A workbench keeps a shared task list in a plain WORKBENCH.md that you and your agents both see, while a project optimizer scores how well a repo is set up for agents and offers one-click fixes. Underneath, the cavrn terminal engine captures every turn, tool call, result and table as structured, agent-readable metadata, so agents can read each other's sessions rather than just watching output scroll by.

Practically, crystl aims to replace a scattered stack. Floating glass cards deliver approvals, questions and notifications without hunting through windows; token tracking shows what each turn and skill costs; an MCP manager connects tools and data; a markdown editor and web preview sit beside your sessions; and remote development over SSH keeps every feature working on a remote machine. There is also a free iPhone app for steering agents over Wi-Fi or via an encrypted relay, and a built-in CLI that lets agents themselves spawn shards and handle approvals. Open models can run locally or through a managed host, so you can mix frontier and open-weight agents in the same workspace.

**Pricing & Plans:** Freemium. A free tier covers getting started and core features, while heavier orchestration capabilities such as orchestrator anointing and controlling other shards via the CLI are gated behind the paid "guild" tier. Pricing details are listed on the site's pricing page and the app is also distributed on the Mac App Store and App Store.

- **Multi-agent parallel sessions:** Run several CLI agents in one project simultaneously, each isolated in its own git worktree and branch so sessions never collide.
- **Orchestration and quests:** Anoint an orchestrator that genuinely monitors workers and reads their terminals, or convene a roundtable of role-played agents in a shared chat via crystl quest.
- **Structured terminal engine (cavrn):** Turns, tool calls, results and tables are captured as agent-readable metadata and rendered fast on the GPU with Metal.
- **Floating approvals and token tracking:** Approval requests, questions and alerts appear as color-coded glass cards, while a panel tracks token burn and estimates turns left.
- **Project-native setup files:** Instructions, task lists and direction live as plain markdown like CLAUDE.md, AGENTS.md and WORKBENCH.md committed with your code, plus an optimizer that scores repo readiness.

**Strengths:** Genuinely model- and agent-agnostic, running any CLI agent including open models; Worktree isolation plus orchestration solves real multi-agent collisions; Agent context lives in plain markdown files inside the project, not locked in a proprietary store; Strong remote development story with SSH support and a free iPhone companion app

**Limitations:** macOS-only, so Windows and Linux users are served by SSH remote development rather than a native app; Some of the most valuable orchestration features are gated behind the paid guild tier; Managing many parallel agents has a real learning curve and demands familiarity with git worktrees
