ADE vs Page Agent: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of ADE and Page Agent — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

ADE

Free

An open-source agentic development environment that runs every major AI coding agent, synced across web, desktop, terminal, and mobile.

Multi-Agent Support: Runs Claude Code, Codex, Cursor, Factory Droid, and OpenCode inside one workspace so developers do not switch UIs.
Cross-Surface Sync: Web, desktop, terminal, and mobile clients share the same chat history and state in real time.
Per-Task Git Worktrees: Every task spins up its own worktree so parallel agents ship features without merge collisions.
In-App PR Review: Review, edit, and merge pull requests generated by agents without leaving ADE.
Bring Your Own Subscription: Reuses whichever coding-agent subscriptions the developer already pays for.
Open Source Core: AGPL-licensed and free to run locally, with full source available on GitHub.
Mobile Continuation: Kick off a feature on desktop and steer or approve it from the phone with identical context.

Agent Fleet Coordination: Run several coding agents in parallel on different features without merge conflicts.
Cross-Device Development: Start a coding task on a laptop and continue it seamlessly from mobile while traveling.
PR Triage: Review, comment on, and merge agent-generated PRs in-app instead of jumping to GitHub.
Consolidated Tooling: Replace several standalone AI-coding UIs with one workspace that speaks to all of them.
Self-Hosted Dev Environment: Teams that need code isolation run the open-source ADE stack on their own hardware.

Page Agent is an open-source in-page GUI agent — a single JavaScript library gives any web page its own AI agent, no extension or backend needed.

In-Page GUI Agent: A single JavaScript include gives any web page its own AI agent that lives inside the page, with no extension or backend required.
Text-Based DOM Manipulation: Operates on the DOM through text — no screenshots or multi-modal LLMs, so it's lightweight and privacy-friendlier.
Bring Your Own LLM: Works with most mainstream models and locally-deployed LLMs so teams stay in control of prompts and data.
Optional Chrome Extension: A companion Chrome extension lifts the agent out of a single page so it can drive multi-page tasks and cross-tab workflows.
MCP Server (Beta): An included Model Context Protocol server lets external agents connect and control Page Agent from outside the browser tab.
Ships as an npm Package: Distributed as `page-agent` under an MIT license with TypeScript typings and a small bundle size.

SaaS AI Copilot: Ship an in-product AI copilot in an existing SaaS web app without building a browser extension or backend agent.
Onboarding & Guided Tours: Have the agent walk new users through the UI step-by-step, interacting with the real DOM.
Web Automation: Automate repetitive DOM tasks (form fill, data extraction, batch updates) driven by natural-language instructions.
Multi-Page Workflows: Combine with the Chrome extension to drive workflows that span multiple tabs and origins.
Agent Orchestration via MCP: Let external agent frameworks control a live web page through the MCP server for testing or automation.
