## Persona

Persona is a VanillaJS UI library built for developers who want a production-grade AI chat surface without adopting a frontend framework. You add it with a single npm install or a CDN script tag, point it at any Server-Sent Events endpoint, and get a streaming chat experience with agent loops, tool use, and style isolation via Shadow DOM.

The library is deliberately decoupled from any particular model provider. Because it consumes generic SSE streams, it works alongside backends built on the Vercel AI SDK, OpenAI Agents, LangGraph.js, Hono, Express, SvelteKit, or a hand-rolled node:http server. Pluggable hooks such as customFetch and parseSSEEvent let you adapt nearly any request or event shape without forking the widget.

Beyond chat, Persona leans into the browser as an agent runtime. Its WebMCP support lets you register page-level tools on document.modelContext — search, carts, bookings, forms — which the agent can discover and invoke with built-in user approval. Layout, theming, and dark mode are controlled through a three-layer token tree and a live theme editor, so the widget can match a brand without rewriting styles. It is created by the team at Runtype and released under the MIT license.

**Pricing & Plans:** Persona is free and open source under the MIT license, so the widget itself carries no cost. The maintainers (Runtype) offer an optional hosted backend and CLI workflow for spinning up agents and client tokens, which is the commercial path, but any compatible SSE backend can be used instead.

- **Zero framework dependencies:** Built in pure JavaScript with no React, Vue, or Svelte requirement, so it drops into any stack via npm or a single CDN script tag.
- **Any SSE backend:** Streams from a generic Server-Sent Events endpoint, with pluggable customFetch and parseSSEEvent hooks to adapt arbitrary request and event shapes.
- **WebMCP-native tool use:** Registers page-level tools on document.modelContext so the agent can discover and invoke actions like search, carts, and bookings with user approval.
- **Style isolation:** Renders inside Shadow DOM with prefixed CSS, keeping widget styles and host page styles fully separated in both directions.
- **Three layout modes and token theming:** Switch between floating launcher, docked copilot, and fullscreen assistant by config, and restyle via a three-layer design token tree with dark mode.

**Strengths:** Pure JavaScript with no framework lock-in, installable via npm or a single script tag; Model- and backend-agnostic thanks to generic SSE streaming and adapter hooks; WebMCP support turns existing page functionality into agent-callable tools; Shadow DOM isolation and token-based theming make it safe to embed in styled sites

**Limitations:** You still need to supply and host your own SSE chat backend, so it is not an out-of-the-box chatbot; Configuration depth (tokens, parsers, adapters) means a non-trivial learning curve for advanced customization; The optional hosted Runtype workflow is the smoothest path, which nudges teams toward that vendor

## T3 Code

T3 Code is an open-source application for developers who juggle more than one AI coding agent. Instead of switching between terminals, editors and vendor dashboards, it provides one surface where threads with Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok can run side by side. Critically, the project does not resell model tokens: you plug in the credentials and subscriptions you already have, so your existing plan and quota remain yours. Models can even be switched mid-thread, letting you move a task to a different harness without losing conversation context.

**Pricing & Plans:** Free and open-source. There is no T3 Code subscription; you bring your own existing Claude Code, Codex, Cursor or similar subscription and pay those vendors directly.

- **Multi-Agent Orchestration:** Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
- **Bring Your Own Subscription:** No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
- **Git and PR Workflow:** Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
- **Forkable and Self-Hostable:** Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
- **Desktop and Mobile Access:** Available on macOS, Windows and Linux with iOS, Android and browser connect options for remote machines.

**Strengths:** Free and open source with no vendor subscription for the tool itself; One interface for several major coding agents instead of scattered terminals; Bring-your-own-subscription model with no token reselling or quota caps; Mobile and browser access plus Git, diff review and PR automation built in

**Limitations:** Requires your own paid agent subscriptions to be genuinely useful; Self-hosting and configuration are your responsibility, with community rather than vendor support; Rapidly evolving project means features and stability can shift between releases
