Build the tools you actually want.
Own them completely.
Build exactly what you need using AI coding tools like Claude Code, Cursor, or Codex — deploy to Leash and your auth and integrations are already there from the last app you built. Each app gets its own database, provisioned automatically.
You built a Forex tracker, an invoice manager, and a habit app with Claude Code. You set up Supabase three times, configured OAuth three times, wired the same integrations three times. Leash makes that work happen once.
How it works
From idea to live app — without the setup tax
Your database, auth, and integrations are configured once. Every new app you build just works.
Step 01
Build with any AI tool
Use Claude Code, Cursor, or whatever you prefer. Build exactly the app you need — invoice tracker, trading dashboard, personal CRM — no compromises.
Step 02
Deploy with one command
Leash auto-detects your framework, wires your database, and publishes it. Your integrations from other Leash apps are already available — no setup twice.
Step 03
Use it everywhere, forever
Live at myapp.leash.build. All your tools in one place — one login, shared database, no subscription stacking.
The difference
Set up once. Every app just works.
Today you repeat the same setup every time you build something new. Leash makes that work happen once.
Without Leash
Configure everything from scratch, every time.
With Leash
Leash — configured once
Each app gets its own isolated database by default. Opt into a shared DB when you want apps to share data.
The compounding advantage
Every app you build makes the next one faster
Configure once. Reuse forever. The more you build on Leash, the more powerful it gets.
Isolated by default. Shared when you want.
Every app gets its own database automatically — your recipe app and todo list stay separate. When you want apps to share data, opt into a shared DB in one line.
Sign in once, everywhere
Log in with Google once. All your Leash apps share that identity — no separate login for your invoice tool, your habit tracker, and your trading dashboard.
Wire once, use in any app
Connect Stripe, Notion, Slack, or any API once in Leash. Every app you build can reference those credentials without re-configuring secrets.
Pre-wired in every project
The Leash SDK gives you database access and auth in two lines of code. No boilerplate, no environment variable hunting.
CLI-first
Two minutes to your first deploy
If you can run npm install, you can deploy to Leash.
What makes Leash different
Built for how AI-assisted development actually works
Not another generic deployment platform. Leash is designed around the way you actually build — fast, iterative, and with more apps coming.
Zero-config deploy
Auto-detects Next.js, Vite, Expo, and any Node.js app. One command to go live — no Dockerfiles, no CI pipelines, no YAML.
Auto database
Each app gets its own isolated Postgres database, provisioned automatically. Opt into a shared database when you need apps to talk to each other.
Reusable integrations
Connect Stripe, Notion, Slack, or any API once. Every app you build can reference those credentials without touching secrets again.
Team access control
Public, private, or locked to a company email domain — enforced at the proxy level. No auth logic to write, no invite system to build.
Preflight checks
Leash validates your build, environment variables, and framework config before deploying. Catch errors locally, not in production.
12 frameworks supported
Next.js, Vite, Remix, Astro, SvelteKit, Nuxt, Express, Fastify, Hono, Expo, plain Node, and static sites. Works with Claude Code, Cursor, Codex — whatever you used to build it.
Your app deserves more than localhost
You built something useful. Deploy it so the people who need it can actually use it.
