Why Harakumo

Stop stitching. Start shipping.

A real app needs hosting, a database, files, sign-in, email, payments and AI. Bought from different vendors, that is seven bills, seven dashboards and seven ways to break. On Harakumo it is one account your AI can run end to end.

Stitching it together

7 vendors
Invoice #7 this month · another vendor, another card on file
Storage key expired in production · uploads failing since 02:14
Sign-in provider is down · nobody can log in to your app
Which dashboard has the error? · 5 consoles, 5 logins
Webhook secret rotated in one place · payments stopped reaching your app
The AI wrote code for the wrong SDK · three vendors, three sets of docs

An illustration of a typical setup, not a measurement.

The platform

Everything your app needs.
One account.

Each service works today and sits behind the same key. Where something is missing, its docs say so. Not built yet: Postgres, social sign-in beyond Apple and Google, auto-deploy on git push, function logs, rate limits per site, and custom HTTP tools for agents.

Deploy

Static sites on the edge and Node.js apps in containers, at your-project.harakumo.app. Deploy from GitHub, a folder, the CLI or a chat; a failed build never replaces what is live.

Beta

Functions

One JavaScript file on the edge with its own URL and no server to size. Write it in the dashboard or send it from the API.

Domains

Search for a domain, pay from your balance and it connects itself, or bring one you already own. DNS editing, auto-renew and transfers included.

Beta

Shield

Block visitors from the countries you choose, addresses and ranges you list, and AI crawlers that say who they are; never serve the .env files, dotfiles or keys that sit beside your pages; put a static site behind a password; and see your workspace’s security checks in one place. HTTPS redirect and security headers on static sites, server apps, functions and worker.js programs, and network-level attack protection always on.

Beta

Repos

A code home inside Harakumo: numbered commits you can deploy, and roll back by deploying an older one.

How it works

From one key
to a running product.

One example, a small online store, built up one family of services at a time.

  1. Start with one key.

    A workspace holds your projects, and one API key reaches every service in it. Create a project and it has a home.

    const hk = new Harakumo({ apiKey });

    • hk_live_…
    • Project · my-store

  2. Put it online.

    Deploy a folder or a repository and the project gets a real address. Each deployment moves through queued, building, deploying and ready, and a failed build never replaces what is live.

    await hk.deployments.uploadDir(project.id, './dist');

    • Deploy
    • Functions
    • Domains
    • Shield
    • Repos
    • ready · my-store.harakumo.app

  3. Give it data.

    The same client opens a SQL database, private file storage, vector search and memory for AI features.

    await hk.databases.query(db, 'SELECT * FROM orders');

    • Databasesproducts and orders
    • Storageproduct images
    • Vector DBsearch
    • Memorycarts

  4. Open it to your users.

    Sign a customer in, take a card payment and send the receipt: three calls from your app. Video and live channels sit in the same family.

    await hk.payments.createSession(account.id, { amountCents: 2900 });

    • Authcustomer login
    • Paymentscheckout
    • Mailreceipts
    • Media

  5. And your AI can run it.

    Your app calls 11 models through the same key. Claude gets its own door: add harakumo.com/mcp, sign in as yourself, and it can deploy, query and manage these same projects by being asked.

Your cloud,
in the conversation.

Harakumo speaks the Model Context Protocol. Add one address to Claude, or any MCP client, and run the platform by asking.

  • You sign in
  • You choose the workspace
  • Read-only, or allowed to change
  • Your role, nothing more

Example conversation

  1. Deploy the latest commit of the store and tell me when it is live.
  2. list_projectsfinds my-store
  3. deploy_projectbuilds the latest commit from GitHub
  4. get_deploymentchecked until readyready
  5. my-store is live at https://my-store.harakumo.app
  6. Audit log · deployment.create · recorded under your name

Try asking

  • Why did the last build fail?list_deployments · get_deployment
  • How much of my plan is left this month?get_usage
  • Buy fruitshop.com and point it at the store.search_domains · buy_domain · connect_domain
  • Create an API key for the staging server.create_api_key

What it changes in your setup, such as deployments, domains, keys and environment variables, lands in your audit log. Everyday calls, such as a query, an email or a checkout link, are counted as usage instead. You can disconnect it at any time. Tested with Claude.

Build standard

Your AI builds it right.
The first time.

Every assistant connected to Harakumo follows one standard by default, so you stop asking for the same things on every project.

  • A tab icon, titles and link previews

    Made first, on every page, so a shared link shows a proper card.

  • Every screen size, from the first build

    Phone, tablet and desktop together. No asking for a mobile version.

  • Sign-in done properly

    Full name, confirm password, the show/hide eye button, and a working password reset.

  • Lists that scale

    Pagination, loading placeholders, and empty and error screens. Never a blank page.

  • The pages every app needs

    Home, About, Contact, Privacy, Terms and a footer that links them.

  • An admin dashboard when it needs one

    Users, orders and numbers to manage, checked on the server.

  • One professional look

    One icon set, never emoji, and motion with a purpose.

  • The backend in one call

    Database, storage, sign-in and keys created and wired, only what the app needs.

check_launchmy-store.harakumo.app
  • Tab icon in every size
  • Page titles and link preview
  • Phone layout
  • Privacy and Terms pages
  • About and Contact linked
  • Show/hide on every password field
  • Unknown pages answer 404

All checks pass. Run after every deploy; anything missing comes back with its fix.

Agents

Your AI builds the app.
Agents run when called, scheduled or messaged.

Harakumo knows which agents a kind of app needs, and your AI can design any other. Every project draws its agents as a flow: what starts each one, what it does, and the services it uses. An agent runs when you or your app call it, from the dashboard, the API or the AI connector; on a schedule; when your app sends it a signed event; or when a visitor writes to it from your site, with read-only access to the project's own documents.

What starts it

A customer asks for a timeA visitor chats
Every day at 9:00On a schedule

Every MondayOn a schedule

Agents for a salon booking app

Services it uses

AI gateway
Database
Memory
Mail

Booking assistant: Finds open slots, books the visit and confirms it by email. Starts: a customer asks for a time. Uses AI gateway, Database, Memory, Mail.

Reminder agent: Emails everyone booked for tomorrow a reminder with a link to reschedule. Starts: every day at 9:00. Uses AI gateway, Database, Mail.

No-show follow-up: Offers the customer the next open times. Starts: a booking is missed. Uses AI gateway, Database, Mail.

Weekly insights: Reports bookings, busy hours and no-shows to the owner. Starts: every monday. Uses AI gateway, Database, Mail.

Suggested for your app

A store gets a shopping assistant and a low-stock alert; a salon a booking assistant and reminders. Pick the ones you want and create them, up to 2 on Hobby.

Designed by your AI

Through the connector your AI creates, tests and improves any agent: create_agent, run_agent, update_agent.

Every step on the record

Each run shows the tools it called, what came back and what it cost, paid from any AI your plan includes, then your balance.

Get started

Live in four commands.

Or none: connect your AI and ask it to build. Either way the free plan needs no card.

const { project } = await hk.projects.create({ name: 'my-store' });
let { deployment: d } = await hk.deployments.uploadDir(project.id, './dist');

// Poll until the build settles.
while (!['ready', 'failed'].includes(d.status)) {

Privacy

Your code, your users and your data, kept apart.

Every request is checked against your workspace and your role, so other customers can't read or change your projects, and the teammates you invite see only what their role allows.

  • Walled off from other customers

    An API key belongs to one workspace. A session or AI connector acts for one person, only in the workspaces they are a member of, and a connector can be limited to just one. No one else’s can read or change your code, databases, files or users.

  • Your own database, your own storage

    Each database is a separate database and each bucket a separate bucket. Files stay private, behind links that expire after 15 minutes unless you choose longer.

  • Passwords and keys kept as hashes

    Your password and your app users’ passwords are stored only as salted hashes. API keys and tokens are stored as hashes, and a new key is shown to you once.

  • Secrets out of sight

    Viewers and read-only keys never see your environment variable values, the AI connector never returns them, and your static site never serves .env files or private keys.

  • Card numbers never touch us

    Buyers pay on a hosted checkout page, so card numbers never reach Harakumo or your app.

  • Not sold, not trained on

    We don’t sell your data or train AI models on your code or stored content, and harakumo.com runs no ad trackers.

Our admin tools are on the record. No one at Harakumo can sign in as you. Our staff need two-factor sign-in for every page and action in our admin tools, and opening your workspace there, or changing anything in it, shows in your audit log.

Beyond your plan

Plan limits answer HTTP 402 and rate limits 429, each naming the limit. File storage, database storage and build minutes stop at the limit on Hobby; on Pro, Team and Scale they keep going, paid from your prepaid balance. Server-app awake time on Pro, Team and Scale is paid the same way, at $0.05 per awake hour. AI past any included amount (Enterprise, or a Pro subscription from before these plans) and every domain are paid from the balance. No surprise bills: when the balance is empty or your spending limit is reached, the call is refused.
