JulesPiChoose Jules if you are developers who want to queue up fixes and features and review PRs later. Choose Pi if you are developers who want a fast, minimal, hackable terminal agent with full control over context and models.
In our editorial scoring, Pi leads in 3 of six categories (reliability, speed and value), while Jules leads in 2 (autonomy and ease of use). On price, Jules runs free tier / google ai plans and is proprietary; Pi runs free (mit) — bring your own model and is open source.
Give your chosen agent more room to build, test and iterate. Standard Compute stretches your compute through automatic provider selection and smart routing. Plans start at $19/month with $20 in monthly compute. Choose your agent below to connect. Eligible new accounts can try $0.25 of compute with no card.

Jules is Google's asynchronous coding agent, powered by Gemini. Unlike interactive agents, you assign it tasks — bug fixes, dependency bumps, small features — and it clones your repo into a cloud VM, writes and tests the change, and comes back with a pull request and an audio changelog summary. The free tier makes it an easy add to any workflow, but the async model means it suits queued, well-defined tasks rather than tight pair-programming loops, and turnaround depends on task queue and complexity.
Pi is an open-source terminal coding agent and agent harness created by Mario Zechner (badlogic, creator of libGDX) and published under MIT by Earendil. Its philosophy is radical minimalism: by default the model gets a small set of tools — read, write, edit, bash — and everything else, from subagents to plan mode, lives in TypeScript extensions. That keeps the loop fast, the context clean, and the behavior fully under your control. It supports 30+ model providers with mid-session switching, session branching and compaction for long tasks, and custom OpenAI-compatible providers via a simple models.json.
