The problem, in one line

The part of software that used to be hardest, writing the code, is no longer the hard part. Keeping a fast-moving codebase aligned with what you meant to build is.

  • ReviewedSecurity and architecture checked before launch, not after an incident.
  • PricedEvery provider and region on the same terms, before you commit.
  • OwnedDeployed into your own account. Your keys, your exit.

Two ways in

Start from an idea, or from the app you already generated.

Concept to production

Start from a description and a goal.

passo.build writes the spec, builds, secures and deploys. You stay on the product, not the plumbing.

MVP to production

Bring what you built in Claude, Codex, Cursor, Lovable or Replit.

The common case. passo.build reviews what exists, closes the gaps, and takes it the rest of the way to a running product on your account.

Security

A failed check is not a report. It is a task.

Nobody can promise completely secure. We promise the obvious things are handled before anything ships: findings become work for your coding agent, and you see what was fixed and who signed off on the rest.

Your coding agent

Connect your coding agent.

Same account, same guardrails, driven from the tool you already use.

terminal
claude mcp add --transport http passo https://staging-mcp.passo.build/mcp

Sign in once in the browser. No API keys, nothing to store. Restart your agent after adding the server.

Portability

Same architecture. Any provider.

Switch the provider and nothing else changes. Compare them before launch, and again whenever the price does.

Architecture unchanged

AWS, in your account
Example regions
us-east-1eu-central-1ap-southeast-1
What changes
The price and the region list. Nothing else.

Your account

Deployed where you own the keys.

Bring your AWS, Azure or DigitalOcean account, or let passo.build hold one for you until you want it back. Nothing is hosted on our side that you cannot take with you.

  • Your credentials never leave your account
  • Your infrastructure is visible in your own console
  • Your exit provider portability is on our roadmap

Once the code is ready

Four questions decide where it lives. You answer, or accept the default.

passo.build proposes a default for each one from what it knows about your application. Every choice stays yours.

  1. 1

    How should it run?

    Architecture

    • Virtual machine
    • Managed containers
    • Kubernetes

    The same code can run on one machine or on a cluster. A startup with a few customers and a team expecting growth need different shapes.

  2. 2

    Where in the world?

    Provider and region

    • AWS
    • Azure
    • DigitalOcean
    • Your own account

    Through your own cloud account or one we hold for you. Any region.

  3. 3

    How many copies?

    Environments

    • Prod
    • Dev + Prod
    • Dev + Staging + Prod

    At least two, so a release never takes down your users. Dev can idle until there is something to test.

  4. 4

    Is it healthy?

    After deploy

    • What is running
    • What is not
    • Cost

    Full control of the environment, complete transparency, from the moment it goes live.

How it works

Three things happen to your repository.

  1. Point it at a repository.

    passo.build reads what the app actually is: the services, the data it keeps, the traffic it expects. You confirm a few things in plain language. No YAML.

    • Works with an existing repo or one you are about to generate
    • Questions, not configuration files
    • Your coding agent can answer for you

  2. Security, architecture and cost, reviewed before anything exists.

    Nothing is provisioned until the code has been reviewed, the architecture fits the app, and you have seen what it will cost on each provider.

    • Vulnerabilities and leaked secrets caught before launch
    • An architecture derived from the code, not a template
    • Providers and regions priced on equal terms

  3. Deployed to the cloud account you own.

    The deployment goes into your account, with a record of what went out, what it costs and how to roll it back. Provider portability without starting over is our roadmap goal.

    • Your credentials, your infrastructure, your exit
    • A record for every release
    • Roadmap: move providers when the price changes

Coding is no longer the bottleneck to software creation. Understanding the market is what you need to build something of value. passo.build handles the scaffolding and the orchestration. Your creativity sets the ceiling, and you stay in control.

Take a repository from generated to running.

Connect a repository and get the first assessment. The review, the comparison and the deploy plan follow from what the code actually is.
