The short version

Updated 2026-08-03

This is the rare comparison where one agent is literally a fork of the other, and the fork disagrees with the original's philosophy. Pi (pi.dev), by Mario Zechner, argues a coding agent should be tiny: read, write, edit, bash — with subagents, plan mode, and everything else as opt-in TypeScript extensions. The payoff is speed, a clean context, and total auditability.

Oh My Pi (omp), Can Bölük's fork, argues the opposite: bake the power tools in. It rewrote the engine in Rust and added hash-anchored edits, LSP diagnostics and refactoring, real debugger control via DAP, subagents, plan mode, hindsight memory, and persistent code cells — as first-class features rather than extensions. It's the more capable tool on day one and the more complex one every day after.

They share DNA, both are MIT-licensed and bring-your-own-model, and both accept custom OpenAI-compatible endpoints. The fork question is really the philosophy question: extensions when you need them, or capability built in before you ask.

Choose omp if…
  • You want IDE-grade tooling — LSP, DAP debugging, subagents — without assembling it
  • Hash-anchored edit safety matters for long or autonomous sessions
  • You'd rather configure a powerful default than build up from a minimal one
Choose Pi if…
  • You value the fastest possible loop and a deliberately small context
  • You want to audit and control exactly what the agent can do
  • The extension model — add only what you use — matches your taste

Verdict: omp or Pi?

Updated 2026-08-03

Choose Oh My Pi if you are power users who want IDE-grade tooling — LSP, debuggers, subagents — inside a terminal agent. 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 ease of use), while Oh My Pi leads in 2 (output quality and autonomy). On price, Oh My Pi runs free (mit) — bring your own model and is open source; Pi runs free (mit) — bring your own model and is open source.

Across 126 community votes on this matchup, Oh My Pi currently leads in 5 of six categories. Cast your own vote above to move the needle.

Where omp falls short
  • A young, fast-moving project — expect sharp edges and frequent releases
  • 32 built-in tools means more surface to configure and more context overhead than minimal agents

Where Pi falls short
  • Minimalism is a trade-off: no LSP, browser, or debugger tools out of the box
  • Getting the most out of it means writing or installing extensions — a power-user tool

In-Depth Comparison

Oh My Pi Overview

Oh My Pi (omp) is Can Bölük's fork of Pi, rewritten as a coding-first surface with a native Rust engine doing the heavy lifting. Where Pi stays deliberately minimal, omp packs an IDE-grade tool surface into the terminal: hash-anchored (hashline) edits that reject stale patches before they corrupt files, LSP-powered diagnostics and refactoring, real debugger control via DAP, persistent Python and JavaScript cells, browser automation, subagents, plan mode, and hindsight memory. It routes across 40+ providers by intent and accepts custom OpenAI-compatible endpoints via a models.yml.

Pi Overview

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.
