oh-my-pi
A coding agent with the IDE wired in: a fork of Pi from Stencil Labs.
oh-my-pi (omp) is a terminal coding agent built by Stencil Labs as a fork of Mario Zechner's Pi. It wires IDE abilities into the agent loop. The README lists support for 60+ providers, 31 built-in tools, 14 LSP operations and 28 DAP (debugger) operations, on a Rust core of roughly 80k lines. It installs through a shell script, Homebrew, Bun or Nix. The Nix flake also exposes NixOS and Home Manager modules for declarative configuration.
Pros & cons
Each point cites its sources and says what kind of evidence backs it. A second reviewer tried to refute every claim before it was kept.
Pros
- User reportsSome HN users rate it highly ('currently the very best'), and one got it running with Z.ai without tweaks beyond picking a model.[1][2]
- User reportsEasily pulls in search from Codex, Gemini and other providers, and runs natively on Windows without WSL.[1][2]
- MetadataMIT licensed, ships very fast (v18.13.3 on 2026-10-28), about 37k stars.[1]
Cons
- User reportsUsing consumer-subscription OAuth logins outside the official tools risks an account ban, as one user found.[1]
- User reportsCritics say it piles on features without ablation evidence, and that hash-anchored edits waste turns in practice.[1][2]
- User reportsProvider-specific breakage: false Antigravity 429s and DeepSeek V4 Flash repeatedly misusing the edit tool.[1][2][3]
- MetadataAbout 2,531 open issues, a very large backlog for a project started in Dec 2025.[1]
- Best for
- Power users who want a feature-rich, multi-provider fork of the pi harness with IDE wiring.
- Watch out for
- Subscription ToS risk with OAuth providers, and edit-tool compatibility with your chosen model.
