PortBayvsCline
Cline is a heavyweight: an open-source agent runtime that runs in your terminal, drives many model providers (including local models via Ollama), and orchestrates parallel agents on a Kanban board, each isolated in its own git worktree, with agent teams and dependency chaining. PortBay takes a different role — it doesn't run its own model; it dispatches the agent CLIs you already use from a card, and its real edge is the environment around that card: a live database, trusted HTTPS on a real domain, email capture and a public tunnel.
Which one is right for you
You want the full stack, open source.
You want to dispatch the agent CLIs you already run (Claude Code, Codex, Cursor) from a native macOS app, and you want the agent working inside a real environment — a running database, HTTPS on a .test domain, a tunnel to demo — that's also your everyday local dev tool.
It already fits your workflow.
You want a provider-agnostic agent runtime with local-model support (Ollama), agent teams with coordinators and specialists, per-card git worktrees, dependency chaining, and cross-platform support on Windows and Linux. Cline is a deeper orchestration engine; PortBay deliberately leans on your existing agents instead of running its own.

Coming from Cline
Cline and PortBay solve different layers, and pair well. Cline is the agent runtime — keep it for local models, agent teams and parallel worktrees. PortBay is the environment and the board: add your project, press play to get a database and HTTPS, and dispatch Claude Code, Codex or Cursor from a card so the agent builds against a running app. You can even point your Cline-driven workflow at the services PortBay provisions.
- Install PortBay and add your project folder.
- Press play — PortBay provisions the runtime, database and HTTPS for it.
- Dispatch your agent from a card; it works against the live app PortBay is running.
PortBay vs Cline, in plain terms
Is PortBay an alternative to Cline?
Partly. They overlap on the Kanban board that dispatches coding agents, but Cline is a full agent runtime (it drives the model, supports local models via Ollama, and runs agent teams), while PortBay dispatches the agent CLIs you already use. PortBay's distinct value is the environment around the card — a running database, HTTPS, email capture and tunnels — plus being your everyday local dev tool.
Does PortBay support local models like Cline?
Not directly. Cline can run local models through Ollama or any OpenAI-compatible endpoint. PortBay dispatches your installed agent (Claude Code, Codex, Cursor, Antigravity); whatever model that agent uses is what runs. If built-in local-model support is essential, Cline covers it natively.
What can PortBay do that Cline can't?
PortBay runs the environment the agent builds against: managed PHP/Node runtimes, a per-project MySQL or PostgreSQL database, trusted HTTPS on a real .test domain, Mailpit email capture and a one-click public tunnel — all in a native macOS app that's also your local dev environment. Cline orchestrates agents and git worktrees but doesn't provision the runtime, database or server.
Does Cline run on Windows and Linux?
Yes. Cline runs on macOS, Windows and Linux (Node 22+). PortBay is macOS-only (Apple Silicon; Intel coming soon). If you need Windows or Linux, Cline is the cross-platform option.
Which should I choose?
Choose Cline for a provider-agnostic agent runtime with local models, agent teams and cross-platform parallel worktrees. Choose PortBay when you want to dispatch your existing agents from a native Mac board and have them work inside a real running environment — database, HTTPS and tunnels included.
