Superconductor vs Jules

Jules is Google's AI coding agent, powered by Gemini models. It offers a generous free tier and high concurrency on paid plans, but is limited to Google's models and has a minimal feature set compared to Superconductor.

Quick comparison

Why choose Superconductor over Jules?

Any agent, any model

Jules locks you into Google's Gemini models and their proprietary agent. No Claude, no GPT, no choice.

Superconductor lets you run five different coding agents across models from Anthropic, OpenAI, and Google. Use Gemini when it's the best fit, Claude when it is, and GPT when that makes sense. Our benchmarking helps you figure out which is which.

Live preview and real environments

Jules can run Docker, but it doesn't give you a live preview of your running app. You can't see what the agent is building until you pull the code and run it locally.

Superconductor shows you a live preview of your app updating in real time as the agent works. You also get terminal access to the same environment, so you can debug alongside the agent.

AI-powered code review

Jules has an internal "critic" agent that pre-reviews code before showing it to you, plus an activity feed with step-by-step explanations. But it doesn't organize changes into logical groups or add inline comments the way Superconductor does.

Superconductor's Guided Review organizes changed files logically, adds inline comments on important changes, and provides summary explanations. QA Checks run an independent QA pass with a score and follow-up list. Both work for all agent types and dramatically reduce review time.

Granular network access controls

Jules runs agents in Google Cloud VMs with internet access, but offers no user-configurable controls over which domains agents can reach. You can't restrict agents to specific APIs, block access to sensitive services, or create domain allowlists — every task runs with full network access.

Superconductor's network sandboxing gives you three modes:

• No access — Complete network isolation for security-sensitive projects
• Custom access — Pick exactly which domains agents can reach, with optional read-only restrictions per domain
• Full access — Unrestricted internet when you need it

Custom access is the default, and includes a curated set of trusted package registries (npm, PyPI, RubyGems, Docker Hub, and more) out of the box. You can add custom rules for your own APIs and services. If an agent tries to reach a blocked domain, you get a warning in chat and can allow it with one click.

This matters for compliance, security-sensitive codebases, and preventing agents from making unintended external calls.

Richer feature set

Superconductor offers features that Jules doesn't have:

• Real-time work log — See exactly what the agent is doing as it works. Jules lacks a detailed work log, so it's hard to tell if the agent is stuck or making progress.
• QA Checks — Run an independent QA pass against any implementation (beta)
• Email triage — PM agent that converts emails into tickets (beta)
• Video input — Attach videos to tickets for agents to analyze
• Native Slack integration — Monitor agents and interact with them from Slack (Jules only offers Slack via API)
• Native iOS app — Full-featured mobile experience with push notifications and Siri

Built for teams

Jules is currently available only for individual Google accounts (ending in @gmail.com). There are no team plans, shared workspaces, or ways for multiple team members to collaborate on the same task.

Superconductor is built around workspaces. Your whole team sees the same tickets, can jump into the same implementation to chat with the agent, review code together, and stay in sync — without leaving the platform.

Multi-repo support

Jules works with one repo at a time. Superconductor supports multi-repo projects, so agents can work across your full codebase and create separate PRs for each repo.

When Jules might be a better fit

• You want a free tier — Jules offers 15 free tasks per day. Superconductor is free during the beta but will have a paid tier for compute in the future.
• You only use Gemini models and don't need other agents
• You need GitHub Issues integration — Jules has it; Superconductor has it planned
• You want scheduled tasks — Jules can run recurring tasks (daily, weekly, monthly) for maintenance like dependency updates and linting. Superconductor doesn't have this yet.
