oh-my-pi (omp) is an MIT-licensed terminal coding agent maintained by Can Bölük at github.com/can1357/oh-my-pi. It is a fork of Mario Zechner's Pi that adds hash-anchored edits, LSP and DAP debugger tools, subagents, and many model providers.

Yes. Run omp on your workstation for coding and a hosted Hermes Agent or OpenClaw bot for always-on chat, scheduled jobs and memory. They share no state and do not conflict.

Comparison

Hermes Agent vs oh-my-pi (omp)

Q: Is oh-my-pi the same as oh-my-cli?

No. oh-my-cli is a separate safety-first code agent CLI. oh-my-pi (omp) is a fork of the Pi coding agent. The names are similar but the projects are unrelated.

Q: Can oh-my-pi replace Hermes Agent?

Not for the same job. omp is an interactive coding agent used inside a repository. Hermes Agent stays running, answers on messaging platforms, runs scheduled jobs and keeps memory across conversations.

Q: Does Hermes Agent write code too?

Hermes Agent can run tools, shell commands and skills, but for long hands-on refactors a purpose-built coding agent such as omp or Claude Code is the better fit.

“oh my pi” has been climbing in search because omp, a fork of the Pi coding agent, has become one of the most feature-dense terminal coding agents available. Hermes Agent solves a different problem: an agent that stays online, lives in your chat apps, and remembers you. Here is how they differ, where OpenClaw fits, and why many people end up running both.

First, which “oh my” is this?

oh-my-pi (omp) is the open-source coding agent at github.com/can1357/oh-my-pi, maintained by Can Bölük and forked from Mario Zechner's Pi. It is not oh-my-cli, a different and much smaller safety-first code agent, and it has nothing to do with the oh-my-zsh shell framework beyond the naming joke.

What oh-my-pi does

omp describes itself as “a coding agent with the IDE wired in”. It runs in your terminal against a repository and is MIT-licensed, installable via a shell script, Homebrew, Bun, Nix, or PowerShell. The features that set it apart:

Hashline edits — patches are anchored by content hash rather than exact string matching, with stale-anchor recovery, so edits land on the first attempt more often across weaker models.
LSP and DAP — renames and diagnostics go through real language servers, and the agent can attach a debugger (lldb, dlv, debugpy) to step through a crash.
Subagents — a task tool fans work out to parallel workers in isolated worktrees and returns schema-validated results.
Many providers — the README lists 60+ model providers, plus project-scoped memory, code review, browser control, and session sharing.

What Hermes Agent does

Hermes Agent, from Nous Research, is a long-running personal or team agent. It connects to Telegram, Discord, Slack, WhatsApp and other platforms, keeps persistent memory, writes and reuses skills, calls MCP tools, and runs scheduled jobs. OpenClaw sits in the same category with its own plugin and channel ecosystem; see Hermes Agent vs OpenClaw for how those two differ.

The real difference: presence vs precision

omp is optimised for the hour you spend in a codebase: every tool is tuned so the model edits, searches, and debugs accurately. Hermes Agent is optimised for the other 23 hours: something that answers a message at 3am, posts a morning briefing, and remembers what you told it last week. A quick test — if the job only exists while you are at the keyboard, reach for omp; if it has to happen when you are not, you want an always-on agent.

Running both

The pairing is straightforward. Keep omp on your workstation for refactors, debugging, and reviews. Run Hermes Agent (or OpenClaw) on a server for chat, reminders, research, and scheduled work. If you want the hosted agent to trigger coding tasks itself, give it a dedicated coding workspace rather than pointing it at your laptop.

OpenClaw Launch hosts Hermes Agent and OpenClaw so they stay online without a machine kept awake. omp remains a local tool you install and run yourself.

Hermes Agent vs oh-my-pi FAQ

What is oh-my-pi?

oh-my-pi, invoked as omp, is an MIT-licensed terminal coding agent maintained by Can Bölük (github.com/can1357/oh-my-pi, site omp.sh). It is a fork of Mario Zechner's Pi coding agent that adds hash-anchored edits, LSP and debugger (DAP) tools, subagents, and support for many model providers.

Is oh-my-pi the same as oh-my-cli?

No. They are unrelated projects with similar names. oh-my-cli is a small safety-first code agent CLI built around approval modes and spend caps; we compare it separately in OpenClaw Launch vs oh-my-cli. oh-my-pi is the Pi fork described on this page.

Can oh-my-pi replace Hermes Agent?

Not for the same job. omp is at its best in an interactive session inside a repository. Hermes Agent is built to stay running, answer on messaging platforms, run scheduled jobs, and keep memory across conversations when nobody has a terminal open.

Can I use both?

Yes, and that is the common setup: omp on your workstation for hands-on coding, and a hosted Hermes Agent or OpenClaw bot for everything that should keep working after you close the laptop. They share no state and do not conflict.

Does Hermes Agent write code too?

It can run tools, shell commands, and skills, and it can hand coding work to a dedicated coding agent. For long hands-on refactors a purpose-built coding surface like omp or Claude Code is the better fit. See Hermes Agent with Claude Code.
