ADE vs OpenMontage: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of ADE and OpenMontage — 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.

- Open Source: Released under AGPLv3 with the build documented publicly.
Best for
- Faceless Video Channels: Generating narrated, edited videos from a prompt for YouTube or social channels.
