APPLICATIONS, MADE COMPOSABLE

Stop treating applications like permanently running services.

AppBoundry turns applications into contract-driven, composable capabilities.

An application defines what it is, what it provides, what it requires, and who can use it. AppBoundry discovers the right capability, authorizes it, materializes the implementation, executes it, and records the result.

The application doesn’t need to sit running. The capability runs when it is needed.

WHY APPBOUNDRY?

Composable execution

Applications become building blocks that other applications, platforms, and AI agents can discover and invoke.

Instead of integrating against a running service, compose applications through explicit capabilities and contracts.

THE EXECUTION MODELDiscover → Authorize → Execute → Destroy

THE PRINCIPLEExecution becomes something you request—not something you keep running.

SWITCH THE IMPLEMENTATION

The contract stays stable. The implementation can change.

Your application contract shouldn’t care whether the implementation is written in Rust, TypeScript, Python, or something else. It shouldn’t care which repository contains it—or whether it runs locally, in the cloud, or somewhere else.

Replace a backend, migrate technology, or introduce another implementation without forcing every consumer to rebuild its integration.

TECHNOLOGY AGNOSTIC BY DESIGN

Build with the technology you want. Compose with everyone.

AppBoundry is built on the AppPort Protocol—an open contract and capability model designed to separate application semantics from execution technology.

Your application defines its boundary once. The transport, runtime, language, framework, and infrastructure remain implementation details.

BUILT FOR AI AGENTS

Applications become discoverable capabilities instead of undocumented tools.

Agents shouldn’t have to understand your infrastructure to use your software. They need explicit, authoritative answers.

What does this application do?What capabilities does it provide?What does it require?Am I authorized to use it?Which implementation will execute?What happened?

FROM RUNNING SERVICES TO COMPOSABLE EXECUTION

Compute becomes ephemeral. Application identity remains.

TRADITIONAL ARCHITECTUREApplication → Server → Process → API → Consumer

APPBOUNDRYApplication → Contract → Capability → Authorization → Execution

Your application identity and contract persist independently of any running process. Implementations can be materialized when needed, execute in an isolated environment, commit durable state, and disappear.

ONE BOUNDARY. MANY IMPLEMENTATIONS.

Evolve the implementation without rebuilding the ecosystem around it.

A single authoritative application contract can connect all of the following:

✓ Multiple repositories✓ Multiple implementations✓ Multiple artifacts✓ Multiple execution environments✓ Multiple consumers✓ One durable application identity

WHO IT IS FOR

01

For developers

Define capabilities once. Build implementations independently. Let AppBoundry handle discovery, compatibility, authorization, execution, lifecycle, and provenance.

Your application becomes something other software can actually compose with.
02

For platform builders

Stop maintaining bespoke integration layers. Give applications a common boundary while providers and consumers evolve independently.

Compose systems instead of wiring services together.
03

For AI systems

Give agents access to applications—not just APIs. Discover capabilities, understand requirements, obtain authorization, invoke an implementation, and observe durable results.

The application becomes the unit of composition.

BUILT ON APPPORT

An open protocol for application boundaries.

AppPort defines the contract between applications:

Identity · Contracts · Capabilities · Requirements · Invocation · Events · Streams · Cancellation

AppBoundry provides the authoritative infrastructure around that protocol.

AppPort defines how applications communicate.

AppBoundry defines how applications are discovered, authorized, executed, and governed.

FeltDB makes the resulting authority durable.

THE NEW APPLICATION MODEL

Don’t build another service that has to stay alive.

Build an application with a durable identity, an explicit contract, and composable capabilities.

When something needs it, execute it.When it’s finished, destroy it.The application remains.

AppBoundry

Composable execution for the next generation of applications.
