Agentic Applications You Own

SaaS products lock you into rigid software you can't customize. Agent-native gives you full-featured apps you own, powered by an AI agent that can evolve them.

Start with a full featured template

High-quality, vetted templates that replace tools you're paying for — except you own the code and can customize everything. Try them with example data before connecting your own sources.

The best of both worlds

SaaS tools are rigid and bolting AI on as an afterthought. Raw AI agents are powerful but have no UI. Agent-native apps combine both.

The solution

Agent + UI + Computer

Agent-native apps combine a polished, guided UI with a powerful AI agent that can customize and evolve the app itself.

Agent + UI + Computer

Every agent-native app is three things working together: an AI agent, a full application UI, and a computer (file system, browser, code execution). Everything the UI can do, the agent can do — and vice versa.

Agent

Autonomous AI that reads, writes, browses, and executes code. Customizable with skills and instructions.

Application

Full UI with dashboards, user flows, visualizations. Guided experiences your whole team can use.

Computer

File system, browser, code execution. No MCPs needed for most tasks. Agents work directly with files and tools.

How it works

One framework, one mindset. Everything the UI can do, the agent can do via natural language. Everything the agent can do, the UI exposes through point-and-click interfaces.

Files as Database

All state lives in files. The agent and UI read and write the same source of truth. No traditional database needed.

AI Through the Agent

No inline LLM calls. The UI delegates to the agent via a chat bridge. One AI, always customizable with skills and instructions.

Agent Updates Code

The agent can modify the app itself. Your tools get better over time. Fork a template and keep evolving it.

Real-time Sync

File watcher streams changes via SSE. When the agent writes a file, the UI updates instantly. No polling, no refresh.

Built for teams

Anyone on your team can customize the software to their needs without piling on developers. Enterprise-grade roles, permissions, and git-based workflows keep everything manageable at scale.

Roles & Permissions

Control who can update the app, who can use it, and who can modify agent behavior.

Git-based Workflows

Pull requests and reviews for software changes that matter. You own your repo.

Works Everywhere

Call your agent from Slack, Telegram, or any chat interface. Set up daily digests, automated workflows, and more.

Run anywhere

Agent-native apps run inside a harness — a host that provides the AI agent alongside your app UI. Run locally with open-source tools or in the cloud with Builder for collaboration and team features.

Local / Open Source

  • Run with Claude Code, Codex, Gemini CLI, or OpenCode
  • Full permissions, full control
  • Free and open source
  • Solo development and testing

Builder.io Cloud

  • One-click launch from templates
  • Real-time multiplayer collaboration
  • Visual editing, roles and permissions
  • Cloud computers for every user

Your app code is identical regardless of harness. Start local, go to cloud when you need teams.

Launch in minutes

One command to fork a template locally. Or click to launch in Builder — no setup required.

# Fork a template and start building
npx @agent-native/core create my-app --template analytics
cd my-app
pnpm install
pnpm dev

Software you own, built for the agentic era

Stop renting rigid SaaS. Fork a template, customize it to your exact workflow, and let the agent keep evolving it. Open source. Forkable. Yours.
