The AI-Native App Development Platform

ObjectStack is an AI-native application development platform for teams building applications with AI. Start from source code with the open-source framework and CLI, or develop online in ObjectCloud and Studio. Define objects, permissions, UI, APIs, actions, and AI tool surfaces once, then run them on ObjectOS where every application can interact with AI under the same governance model.

The 100× Compression

Build applications with AI, not just around AI.

A typical enterprise application scatters data models, forms, APIs, permissions, and automation across many files and tools. ObjectStack turns the application into typed metadata that developers and AI coding agents can both read, edit, validate, and ship.

Traditional enterprise app ~50,000 LOC imperative code × a dozen files

ObjectStack ~500 lines typed metadata × one schema × one context window

Stack

Develop with ObjectStack. Run with ObjectOS. Render with ObjectUI.

ObjectStack is the AI-native application development platform. ObjectOS is the AI-native application runtime platform where applications, users, and AI agents interact through governed actions. ObjectUI gives developers controlled interfaces from the same metadata. ObjectQL stays in the infrastructure layer as the query and driver engine.

AI-Native Development Platform

ObjectStack

Start here to build applications with AI. ObjectStack supports source-code development through the framework and CLI, plus online development through ObjectCloud and Studio. Objects, permissions, views, actions, APIs, SDKs, and MCP tools share one metadata model.

AI-Native Runtime Platform

ObjectOS

ObjectOS runs AI-native applications. Every app can expose governed actions and MCP tools so people and AI can interact with the same business system under identity, permission, audit, and policy controls.

Developer UI Engine

ObjectUI

ObjectUI helps frontend developers render controlled React interfaces from ObjectStack metadata while keeping product-specific layout, components, and interaction design in their own hands.

One platform for AI-native application development and runtime interaction.

ObjectStack lets teams build applications with AI; ObjectOS lets those applications interact with AI safely after they are running.

Source-Code or Online Development

Develop from a repository with the framework and CLI, or work online in ObjectCloud and Studio. Both paths produce the same versioned ObjectStack metadata artifacts.

Applications Over Existing Systems

Drivers mount databases, spreadsheets, SaaS APIs, and proprietary systems without forcing migration. AI interacts through governed application actions, not raw storage access.

Application Models AI Can Read

Objects, flows, permissions, views, dashboards, actions, agents, and packages compile into structured artifacts that developers and AI coding agents can inspect and maintain.

One Source for UI, APIs, and AI Tools

ObjectStack starts from typed metadata and derives TypeScript types, JSON Schema, REST contracts, ObjectUI behavior, SDKs, and MCP tool signatures from the same source.

ObjectOS Runs the Application

ObjectOS loads project artifacts, drivers, auth, audit, jobs, webhooks, AI, and policy services into a runtime where every app can expose controlled AI interaction.

AI Interaction With Runtime Guardrails

Approved actions become MCP tools with user identity, permissions, validation, and audit. AI can operate the app, but it does not bypass the app.

From source or online development to AI-operable runtime

Build the application model in ObjectStack, validate and package it, then run it in ObjectOS where UI, APIs, and AI tools share governance.

Develop: Source Code or Online Workspace

Define objects, fields, relations, validation, permissions, views, flows, actions, agents, and packages from code with CLI support, or edit the same model online through ObjectCloud and Studio.

Package: Versioned Application Artifact

ObjectStack compiles the application model into a typed, reviewable artifact. The artifact contains the contracts needed by UI, APIs, SDKs, drivers, and AI tools.

Run: ObjectOS AI-Native Runtime

ObjectOS runs the artifact, enforces identity and permissions, emits APIs and ObjectUI surfaces, and exposes governed MCP tools so applications can interact with AI safely.

Build with AI. Run with AI interaction.

Use the same platform for source-code projects, online development, self-hosted enterprise applications, and AI-operated workflows.

Source-Code App Development

Use the open-source framework and CLI to model an application locally, validate metadata, generate types, and let AI coding agents maintain the same source of truth.

Zero infrastructure overhead

Online Development for Enterprise Apps

Use ObjectCloud and Studio to model applications collaboratively, review metadata, test runtime behavior, and promote artifacts without first building infrastructure.

Wrap existing systems, don't migrate

AI-Interactive SaaS Runtime

Run SaaS applications on ObjectOS so users, services, and AI agents interact through the same governed actions, permissions, audit trails, and tool contracts.

Multi-tenant + agent-ready out of the box

Platform Engineering & Open-Core Products

Use ObjectStack as the open framework underneath your own platform: Zod metadata, plugin runtime, drivers, ObjectUI renderers, and agent tools. Keep your product experience differentiated.

Questions from Decision Makers

Strategic and technical considerations for CTOs and engineering leaders.

How does this reduce our total cost of ownership?

It removes repeated glue: one metadata definition drives objects, APIs, SDKs, UI, permissions, and MCP tools. ObjectOS supplies the runtime plumbing (auth, security, audit, jobs, webhooks, AI), while ObjectUI supplies reusable renderers instead of per-app CRUD screens.

What's our migration path from existing systems?

Incremental. Mount one existing table, spreadsheet, or SaaS API through a driver, define its ObjectStack metadata, and expose only the governed surfaces you need. ObjectQL remains a useful data engine, but you do not have to rewrite the whole system around it.

How do we handle compliance and audit?

Every action — UI, API, SDK, or MCP tool — is logged with principal (user or agent), intent, and resulting metadata change. Field-level permissions are declared in Zod, not bolted on. Deploy on-premise for jurisdictions requiring strict residency.

Can we deploy in air-gapped or edge environments?

Yes. The kernel + artifact bundle runs offline. Deploy on field devices, manufacturing floors, or secure facilities. Sync when connectivity returns. The MCP surface continues to work for local AI tooling.

What's the performance impact compared to native queries?

ObjectOS routes data access through drivers that issue native SQL or native database/API calls. Hot paths can still use custom actions or driver-specific logic while retaining the metadata contract for permissions, UI, and agent tools.

How does this fit with our existing stack?

The framework is TypeScript-first and Zod-based, ObjectOS is a Node.js runtime, and ObjectUI is React-based. Other services can interact through generated REST APIs and MCP tools, so the runtime can sit beside existing systems rather than replace them all at once.

What's the roadmap for enterprise features like SAML SSO?

Auth, OAuth/OIDC, RBAC, RLS, FLS, and audit log are in the open-core today (Apache-2.0). On the roadmap toward ObjectCloud GA (July 2026) and beyond: SAML/SCIM, SIEM export, advanced flow orchestration, SOC 2 attestation. Enterprise customers shape prioritization — join the waitlist to discuss requirements.

How do we make this maintainable long-term?

Zod metadata is plain TypeScript — no proprietary DSL. Types are inferred end-to-end. Artifact bundles are diffable and replayable. Your team owns the metadata; runtimes are replaceable.
