jump.sh

Local dev servers with real HTTPS URLs

No port hunting. No cert wrangling. No DNS config.
Every project gets a stable https://yourapp.jump.sh URL that just works.

Problems jump.sh solves

Port conflicts — Running 5 projects on localhost means remembering which port is which. jump.sh gives each project a named URL.
No HTTPS locally — Service workers, secure cookies, and many APIs require HTTPS. jump.sh provides valid TLS certs automatically.
Branch isolation — Testing a feature branch while main is running? Each git worktree gets its own URL like https://myapp--feature-x.jump.sh.
Agent verification — AI coding agents need stable, predictable URLs to screenshot, test, and verify changes without port guessing.

Quick start

npx jump.sh server
# open https://dash.jump.sh in your browser
# add your project in the dashboard

Run in the foreground to try it out. When you're ready, jump.sh install runs it as a background service.

Built for AI agents

Coding agents need stable URLs to verify their work. jump.sh gives every project a permanent https:// URL that agents can screenshot, test, and hit from any tool — no port discovery or manual setup.

Works with your stack

Docker Compose — detects docker-compose.yml, spins up containers, proxies to them.
Node.js — detects package.json, runs your dev command, proxies to the dev server.
Ports are allocated automatically from a dedicated range — no conflicts across projects.

Git worktrees

Working on multiple branches? jump.sh auto-discovers .worktrees/ directories and gives each branch its own URL:

https://myapp.jump.sh           → main branch
https://myapp--feature-x.jump.sh → .worktrees/feature-x

Run jump.sh add on the main project once. Worktrees are picked up automatically via periodic scanning — no need to register each branch.

Agents working on feature branches can verify changes at the branch-specific URL without interfering with main.

Commands

jump.sh — Open dashboard (or start server if not running)
jump.sh server — Run daemon in foreground (for dev/debugging)
jump.sh open / jump.sh dashboard — Open the dashboard in your browser
jump.sh install — Install daemon service + download certs
jump.sh uninstall — Remove daemon service
jump.sh ls — List projects with status
jump.sh logs [name] — Tail project logs
jump.sh register — Register via GitHub SSH key (provisions *.you.jump.sh)
jump.sh status — Show daemon and domain status
jump.sh dashboard add — Add current directory as a project

Remote access via Tailscale

jump.sh register provisions a subdomain tied to your GitHub username (e.g., *.you.jump.sh) that resolves to your Tailscale IP. Access your dev URLs from any device on the same tailnet — your phone, a colleague's laptop, or a CI runner — no port forwarding or public exposure required.

How it works

*.jump.sh resolves to 127.0.0.1 via public DNS — no local DNS setup needed. The daemon runs on your machine, terminates TLS with a shared wildcard certificate, and proxies requests to your dev servers based on subdomain.

Browser → https://myapp.jump.sh
       → DNS: 127.0.0.1
       → jump.sh daemon (TLS termination)
       → localhost:10042 (your dev server)
