ADE vs Gemini Spark: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of ADE and Gemini Spark — 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.
