## 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

## Replicas

Replicas is a cloud coding-agent platform built for engineering teams who already work with AI coding tools but want them to run reliably off their laptops. Rather than pairing with an agent locally, you delegate a task and Replicas spins up the agent in an isolated cloud Linux VM. It supports a range of harnesses — Claude Code, Codex, Cursor, OpenCode, Pi and Muse Code — and returns a pull request, a reply or a screen recording for you to review, comment on or re-run.

The platform is designed to fit into existing workflows instead of replacing them. You can start agents from Slack channels, Linear issues, GitHub or GitLab comments and pull requests, the web dashboard, or automations via schedules, webhooks and an API. Each task runs in its own isolated VM that shares nothing with neighbouring agents, and environments can be preconfigured with warm hooks that preinstall dependencies, images, MCP servers, skills, files and variables. Agents can also drive a real desktop and browser to install software and verify their own work.

Visibility is a core theme: Replicas reports per-minute attribution across source, person, harness, model, credential and the skills or MCP servers an agent used. The company is backed by Y Combinator and announced a $4M seed round. It advertises $100 of free usage with no card required, alongside paid and enterprise offerings, and counts teams such as Knowunity and Parrot among its customers.

**Pricing & Plans:** Replicas advertises $100 of free usage with no credit card required to start, then offers paid plans plus an enterprise tier. Exact per-seat or usage pricing is quote-based on the site, so check the pricing page or book a demo for current figures.

- **Any harness, isolated VMs:** Run Claude Code, Codex, Cursor, OpenCode, Pi and Muse Code agents, each in its own Linux VM, so you can mix harnesses across tasks.
- **Trigger work where you already work:** Kick off work from Slack, Linear, GitHub, GitLab, the web dashboard, or via schedules, webhooks and API calls — no new workflow to learn.
- **Configured sandboxed environments:** Each agent gets its own configurable machine with warm hooks that preinstall dependencies, MCPs, skills, files and variables for repeatable setups.
- **Full computer use:** Agents drive a real desktop and browser to install dependencies, run services and verify their work, handing back screenshots and screen recordings.
- **Analytics and attribution:** Every minute is attributable to a source, person, harness, model and credential, so teams can see exactly what shipped and what it cost.

**Strengths:** Runs multiple popular coding harnesses (Claude Code, Codex, Cursor and more) in one platform.; Starts work from Slack, Linear, GitHub/GitLab, dashboard, webhooks or API with no new workflow.; Strong isolation: each task gets its own Linux VM with nothing shared.; Per-minute attribution across source, person, harness, model and credential.

**Limitations:** It is a cloud platform, so code and credentials leave your local machine unless configured carefully.; Value depends on you already using harnesses like Claude Code or Codex; it is not a from-scratch IDE.; Pricing beyond the free credit and enterprise tier is quote-based, so exact costs need a demo or pricing page check.; Managing many parallel agents can require new review and governance habits to stay productive.
