A harbor for your
local dev servers.

Stop juggling a dozen terminal tabs. Register each Node project once, then start, stop and watch them all — live logs, automatic port detection, per-project Node versions and dependency-ordered startup for monorepos.

How it works

Three steps to a calmer terminal.

No config files to hand-write. DevHarbor reads what your project already declares.

01
Add a project

Click Add project and pick a folder — no config files, no terminal. DevHarbor reads its package.json, finds your dev scripts, and detects the Node version from .nvmrc or engines.

✓ pnpm · node 20.11.1 · 4 scripts found
02
Define the run order

Add one or more tasks per app — migrate → api → web. DevHarbor waits for each to be ready before starting the next.

migrate
api :4000
web :5173
03
Press start

Everything boots in order with real terminals under the hood. Live logs, clickable ports, CPU & memory — all in one window.

Features

Everything your dev servers need. Nothing they don't.

Real terminals under the hood, so logs look exactly like your shell — with a window built to manage many of them at once.

Searchable, color-accurate live logs

Real terminals under the hood, so every app's logs look exactly like your shell — with search, filtering and adjustable text size. Crashed app? The last lines stay pinned with one-click restart.

[vite] dev server running at http://localhost:5173
[api] listening on http://localhost:4000
GET /api/products 200 · 9ms
[vite] hmr update /src/components/ProductCard.tsx
Monorepo-aware startup

Define multiple tasks per app and DevHarbor starts them in order — waiting for each to be ready before the next.

Automatic Node versions

Reads .nvmrc & engines, then picks from your nvm / fnm / volta / asdf — no nvm use dance.

Layered env variables

Manage them global → per-app → per-task, with secret masking and .env import built in.

Live ports & resources

Auto-detects the port each app binds to with clickable links, plus live CPU & memory per app.

⌘K palette & folders

Group apps into folders, filter instantly and jump anywhere from the keyboard — never touch the mouse.

Everything stays local

All data lives in a local database on your machine. No accounts, no cloud, no telemetry — ever.

Try it

A working window, right here.

This is the real interface. Watch the logs stream live, hit Stop to halt the server, or jump to the Dashboard from the sidebar.

FAQ

The honest facts.

Everything we'd want to know before installing a new dev tool.

Today DevHarbor is macOS only, and built for Apple Silicon (M-series). Windows, Linux, and Intel Mac builds aren't available yet — they're on the roadmap, and being open source means they can land faster with help.
Yes. DevHarbor is free and AGPL-3.0 licensed. There's no paid tier, no account, and no telemetry. You can read every line of the source on GitHub.
Never. All projects, tasks, environment variables and logs live in a local database on your machine. DevHarbor makes no network calls about your projects — there's no cloud component at all.
DevHarbor runs real terminals under the hood, so logs look identical to your shell. But it adds a UI for the things tmux can't: per-project Node versions, dependency-ordered startup, automatic port detection, layered env vars, and live CPU/memory per app.
No — it uses them. DevHarbor detects the Node version a project needs and picks the matching install from whichever version manager you already have. Nothing to reconfigure.
Electron, React and TypeScript. Contributions are welcome — the codebase is structured to make adding new task runners and version managers straightforward.

Bring your dev servers into harbor.

Free, open source, and local. Download once and never count terminal tabs again.
