## 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

## jcode

jcode is an open-source coding agent designed to live in your terminal. Its central claim is performance: the harness is written in Rust so that each extra agent session costs a few megabytes of memory instead of hundreds, and new sessions open in tens of milliseconds. That matters for workflows where the bottleneck is not model intelligence but the ability to keep twenty agents working in parallel without the machine throttling.

The project collects several capabilities usually found in separate tools: agent swarms, durable and semantic memory, background and headless execution, automatic task continuation, MCP support, prompt caching, and routing to hosted model inference or local runtimes such as Ollama and LM Studio. It also includes a self-development mode, letting the agent work on its own codebase under supervision.

jcode publishes its own evaluation research rather than leaning on public leaderboards. Its bench suite (float-print, json-unescape, utf16-transcode) is designed to be uncontaminatable because there is no memorizable answer, hard to saturate because it scores optimization depth, and continuous instead of pass/fail. The harness also tracks agent confidence at task assignment versus completion, forcing re-checks when confidence spikes unrealistically. The project is backed by Y Combinator and distributed through a one-line install script for macOS, Linux and Windows, with a desktop app in beta.

**Pricing & Plans:** Freemium with paid options. Installation and the open-source agent are free; the site lists a dedicated pricing page and an enterprise plan for larger deployments. Consult the official pricing page for current figures.

- **Rust harness with low per-session overhead:** Each additional jcode session costs megabytes rather than hundreds of megabytes, and a new session is ready for input in well under a tenth of a second, so you can run many agents on hardware you already own.
- **Agent swarms and background tasks:** Launch multiple agents in parallel, hand off long jobs to background or headless execution, and keep durable task state so work survives interruption.
- **Benchmark-driven optimization:** The jcode bench suite (float-print, json-unescape, utf16-transcode) scores optimization depth on an analog axis with no capping timeouts, so capability differences stay visible.
- **Confidence-checked completion:** Agents rate confidence when a task item is assigned and again when it is finished; a sudden jump triggers forced re-verification instead of blind acceptance.
- **Flexible model routing:** Works with hosted model inference or local runtimes such as Ollama and LM Studio, plus MCP support and prompt caching for efficient long sessions.

**Strengths:** Open-source agent with a one-command install for macOS, Linux and Windows; Memory footprint per extra session is dramatically lower than typical terminal agents; Runs many parallel agents and durable background tasks from one terminal; Supports local model runtimes and MCP, so it is not locked to a single provider

**Limitations:** Terminal-first interface is not aimed at users who want a graphical editor; Its benchmark claims are self-published, so independent verification is limited; Extracting full value requires comfort with shells, model configuration and agent orchestration
