Why an agent

A chatbot talks about your app. An agent runs it.

The difference isn't the model — it's what it's grounded in and what it's allowed to do. A Web App Agent comes from your code and can use every action your users already have.

A generic chatbot

  • Answers questions about your product
  • Grounded in docs that drift from the code
  • Can't take an action on a user's behalf
  • Goes stale the moment you ship

A Web App Agent

  • Executes the actions your app already exposes
  • Grounded in the repository itself
  • Calls a real, inspectable tool per action
  • Re-analyzes on every push

Grounded in your codebase

Not in a prompt, not in a PDF. The agent is derived from your actual code.

It operates, it doesn't narrate

Ask it to refund an order and it refunds the order — through the same code path a user would hit.

It keeps up with your app

Push a commit and Faustine re-analyzes. Your AI never falls behind your product.

The process

Five stages. Today, not next quarter.

Launch without building an AI team or maintaining the agent infrastructure yourself. Connect your repo and watch the agent assemble itself.

  1. Connect~30 seconds

    Point Faustine at your code.

    Connect your code repository — any git provider works. From here, Faustine keeps the agent in sync with your code.

    • Any git provider
    • Monorepos supported
    • Stays current on every push

    • modules/customers/
    • modules/checkout/
    • auth/session.ts
    • routes.tsx
  2. Analyze~2 hours

    It learns what your app actually does.

    Faustine analyzes your codebase and discovers what your app can do — its modules, its actions, how it authenticates.

    • Modules and actions, from real code
    • Auth and routing, detected
    • You choose the scope

  3. Generate~30 minutes

    Every action becomes an inspectable tool.

    Every action becomes a tool the agent can call. Open any of them, read it, edit it — nothing is hidden behind a prompt.

    • One tool per real action
    • Readable, editable, versioned
    • Drafts never touch what's serving
    agent · tools
    Generated tools12 · all editable
    • createCustomer()
      ← Customers · Create customer
    • updateCustomer()
      ← Customers · Update customer
    • refundOrder()
      ← Checkout · Refund order
    • openDashboard()
      ← Dashboard · View revenue

    every tool maps to real behaviour in your code

  4. Integrate~1 minute

    One line of code in your app.

    Paste a script tag into your index file. That's the whole integration — no SDK to learn, no backend to change, nothing to rebuild when the agent evolves.

    • A single script tag
    • No backend changes
    • Runs on your own domain and auth

    one line · no backend changes installed
  5. ShipInstant

    Your app is AI-Native.

    Publish, and the agent operates your app for real users — with governance, limits, and logging already underneath.

    • It operates, it doesn't just answer
    • Swap models anytime
    • Every call logged

Repo to working agent: the same day

Anatomy

Nothing is a black box.

An agent isn't a prompt with your docs stuffed into it. It's a set of real tools, each one derived from an action your code already implements.

1Modules

The feature sets Faustine finds in your repo.

  • Customers
  • Checkout
  • Dashboard
2Actions

What a real user can do inside each module.

  • Create customer
  • Update customer
  • Refund order
  • View revenue
3Agent tools

One inspectable tool per action. This is the agent.

  • createCustomer()
  • updateCustomer()
  • refundOrder()
  • openDashboard()

Readable

Open any tool and see exactly what it will call.

Editable

An IDE-grade editor, your cloned repo read-only beside it.

Versioned

Drafts and published versions. Serving is never mutated by accident.

After you ship

It gets better on its own. And you can push it further.

Two things happen the day after launch: your code moves, and you start wanting the agent to do things your code can't. Both are already handled.

Always current

You change the code. The agent updates itself.

Faustine re-analyzes on every push. If a change breaks a tool, it's flagged with a proposed fix — you accept it with one click. The agent never falls behind your app.

  • Re-analyzes on every push
  • Stale tools flagged
  • One-click fixes
  • Serving is never touched

Beyond the codebase

Teach it things your code doesn't know.

Some capabilities live outside your repo — an internal service, a partner's API. Write those tools by hand and the agent treats them exactly like the generated ones.

  • Write tools by hand
  • Call any API
  • Connect MCP servers
  • Same governance as generated tools

  • refundOrder()from code
  • checkInventory()custom

  • Your backend
  • Any HTTP API
  • Postgres
  • Stripe
  • Slack
  • Salesforce
  • MCP servers

custom tools are governed, versioned, and logged like the rest

Underneath

The hard parts are already running.

The hard parts of running AI in production come with every agent, on by default.

Book a demo

Provider governance

Swap models and providers with no redeploy and no code change.

Token compression

Prompts are compressed automatically before they reach a provider.

Limits and guardrails

Rate limits and quotas keep the agent well-behaved at any scale.

Both-sides logging

Every call is logged end to end, with a latency breakdown.
