ADE vs Google Stitch: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of ADE and Google Stitch — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
ADE
ADE
An open-source agentic development environment that runs every major AI coding agent, synced across web, desktop, terminal, and mobile.
Key features
- 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.
Best for
- 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.
Google Stitch
Google LLC
Generates UI designs for mobile and web from prompts, sketches, or images to speed design ideation and prototyping.
Key features
- Prompt-to-UI Generation: Produces UI screens for mobile and web from natural-language prompts, sketches, or images to accelerate ideation and mockup creation.
- Sketch and Image Import: Accepts user sketches or images as input and converts them into UI layouts and visual designs to jumpstart the design process.
- Gemini CLI Extension: Provides a Gemini CLI extension enabling natural-language interaction with a Stitch MCP server for generating UIs and managing requests from the terminal.
- MCP Server & Proxy Tooling: Offers an MCP (Managed Control Plane) workflow and proxy utilities to host a Stitch MCP server, route requests, and facilitate local development/testing.
- GCP Integration & Authentication: Integrates with Google Cloud tooling (gcloud) for authentication, Application Default Credentials, project selection, and IAM role setup required to enable the Stitch API.
- CLI-based Setup & Diagnostics: Includes command-line installers and setup commands (e.g., npx @_davideast/stitch-mcp init) that automate installation, enable APIs, configure credentials, and diagnose setup issues.
- Generates UI designs for mobile and web from prompts, sketches, or images
- Hosted Stitch web application for interactive design ideation
- Stitch MCP API for programmatic access and server integration
- Gemini CLI extension to interact with Stitch via natural language commands
- MCP proxy server capability for local/dev proxying of Stitch MCP
- CLI-driven setup and provisioning (npx init, gemini extensions install)
- Google Cloud authentication support (gcloud auth, Application Default Credentials)
- IAM-based access control requirements and project-level service enablement
Best for
- Rapid Design Ideation: Quickly generate multiple UI concepts from a brief or sketch to explore interface directions during early-stage product design.
- Sketch-to-Prototypes: Convert hand-drawn sketches or screenshots into digital UI screens that designers can refine and iterate on.
- Developer Handoff Automation: Produce consistent UI outputs that designers can export or hand off to developers along with configuration for Stitch MCP to streamline implementation.
- CLI-driven Design Workflows: Integrate UI generation into terminal-driven workflows using the Gemini CLI extension for teams that prefer code/CLI environments.
- Enterprise Self-hosting & Control: Deploy and run a Stitch MCP server with GCP integration and IAM controls to maintain access governance and combine Stitch with internal toolchains.
- Local Development & Testing: Use the MCP proxy and diagnostic commands to test Stitch-generated UIs and API interactions in local or staging environments before production rollout.
- Rapid design ideation and exploration of mobile/web UI concepts
- Convert sketches or screenshots into polished UI screens for prototyping
- Automated UI generation in developer workflows via CLI or API
- Integrating AI-driven UI generation into a Google Cloud-based toolchain
- Local development and testing using an MCP proxy server
- CI/CD automation to generate or refresh design assets programmatically
