## Agent-Native

Agent-Native is an open-source framework for building what its authors call agentic applications: software where an AI agent and a human interface are first-class peers rather than an agent bolted onto an existing app. The central idea is that a capability should be defined once. When you declare an action with defineAction(), the same code is callable by the embedded agent, by React components in the UI, by external HTTP clients, and by integrations, so there is no drifting duplicate logic between the automation and the interface.

Around that core, the framework wires together the pieces most agent products end up rebuilding: shared application state so the agent knows what the user is viewing or editing, a shared PostgreSQL database as one source of truth for users and agents, persistent memory and reusable skills, scheduled and event-driven automations, multi-agent teams, and authentication with organizations plus resource-level permissions for viewing, commenting, editing and managing.

Agent-Native is deliberately stack-agnostic. It is TypeScript, open source, and designed so you bring your own LLM, your own database and your own hosting, keeping the application code in your own repository. The project also ships a set of open-source reference apps, including Design, Slides, Clips, Analytics, Calendar, Mail, Content, Assets and Forms, which you can use as-is or fork and customize, and you can start a new project from the CLI or build online through Builder.io.

**Pricing & Plans:** Agent-Native is an open-source framework that is free to use; the project itself is distributed at no cost, and you pay only for whatever you supply yourself, such as your own LLM, database and hosting. Reference apps are described as free to use or customize.

- **One action, every surface:** Declare a capability once with defineAction() and it is automatically available to the agent, the React UI, HTTP clients and integrations, eliminating duplicated logic.
- **Shared state and data:** The agent sees what users are browsing, selecting and editing, and both read and write the same PostgreSQL database as a single source of truth.
- **Skills and memory:** Give agents reusable expertise, persistent context and long-term memory so they stop repeating mistakes and do not need re-explaining.
- **Automations and agent teams:** Run agent work on schedules or in response to events, and delegate to specialist agents within a workspace or across connected agents.
- **Auth, orgs and sharing built in:** Sign-in, user accounts, organization membership, and per-resource permissions for view, comment, edit and manage come wired into the framework.

**Strengths:** Capability is defined once and reused by agent, UI, APIs and integrations, which cuts duplication; Brings your own LLM, database and host, so there is no model or cloud lock-in; Open source TypeScript with application code kept in your repository; Batteries-included auth, organizations, permissions, memory, skills and automations

**Limitations:** Requires TypeScript and full-stack comfort; it is a framework, not a no-code builder; You are responsible for hosting, database operations and LLM costs; The ecosystem and third-party documentation are still relatively young

## Sublayer

Sublayer is an open-source, model-agnostic Ruby framework for building AI agents and automations. It offers a generative AI DSL with base classes — Generators, Actions, Tasks and Agents — that Ruby developers can compose into AI-powered applications. Rather than locking you into a single vendor, Sublayer lets you configure any supported LLM provider and swap models through the configuration layer.

At its core, Generators handle single generation tasks (for example, generating code from a description, or a description from code), while Actions perform the operations that feed those generators or consume their output, such as writing a file or running a test command. Agents are autonomous entities that monitor or perform tasks, driven by Triggers like file-change listeners or time intervals — the classic example being an RSpec agent that reruns tests on change and edits code until they pass.

Sublayer is distributed as the `sublayer` Ruby gem under the MIT license (github.com/sublayerapp/sublayer) and documented at docs.sublayer.com. It supports OpenAI, Anthropic Claude and Google Gemini, the last being marked experimental. Because it is pre-1.0, the project advises pinning a specific minor version in your Gemfile. The framework is especially relevant for Ruby teams building AI code review, automation and agent workflows.

**Pricing & Plans:** Free and open source. Sublunar is available as the MIT-licensed `sublayer` Ruby gem at no cost; you only pay for the underlying LLM API usage from your chosen provider (e.g. an OpenAI API key).

- **Model-Agnostic Providers:** Use OpenAI, Claude or Gemini — or plug in your own provider — without locking your app to one model.
- **Generators:** Reusable classes for single generation tasks such as code from description or a description from code.
- **Actions:** Operations that supply inputs to or act on the output of generators, like writing a file or running a command.
- **Agents & Triggers:** Autonomous entities with triggers such as file changes or time intervals — for example an agent that runs tests and fixes failing code.
- **Open Source & Examples:** Genuine open-source Ruby gem with example projects like Blueprints (an AI code assistant) and Clag (command-line generator).

**Strengths:** Model-agnostic — works with OpenAI, Claude and Gemini; Free and open source under the MIT license; Idiomatic Ruby DSL with reusable Generator, Action and Agent classes; Triggers enable event-driven autonomous agents

**Limitations:** Pre-1.0 with likely breaking changes between minor versions; Ruby-only, so not usable from Python or JS projects; Requires bringing your own LLM API key (e.g. OpenAI); Gemini provider is marked experimental and unstable
