Hermes Agent is a personal agent; Oh My Pi is a terminal coding agent — different tools for different jobs. Here is what each is for, how they differ, and when to run each (or both). Vote for your favorite.

Different jobs, both open source. Hermes Agent (Nous Research, MIT) is a self-improving personal agent: persistent memory, a learning loop that turns completed tasks into reusable skills, self-hosted operation, and access from 20+ messaging platforms. It's built to run continuously and compound.
Oh My Pi is a terminal coding agent — Can Bölük's coding-first fork of Pi with LSP, real debugger control, subagents, and hash-anchored edits on a Rust core. It's built for deep, interactive coding sessions, not for being your always-on assistant.
If your question is 'which should run my life and projects', that's Hermes. If it's 'which should sit in my terminal while I code', that's omp. Many power users run exactly that split — and since both are bring-your-own-model, they can share one API endpoint.
HermesompChoose Hermes Agent if you are power users who want a long-running personal agent that learns and compounds. Choose Oh My Pi if you are power users who want IDE-grade tooling — LSP, debuggers, subagents — inside a terminal agent.
Editorially this matchup is a dead heat: each agent leads in 3 of our six categories. On price, Hermes Agent runs free (mit) / models via standard compute and is open source; Oh My Pi runs free (mit) — bring your own model and is open source.

Hermes Agent is Nous Research's open-source autonomous agent, released in February 2026 under the MIT license. Its defining feature is a built-in learning loop: after completing complex tasks it writes its own reusable skills, improves them with use, and builds persistent cross-session memory of you and your projects. It runs self-hosted — from a $5 VPS to a GPU cluster — works with 200+ models, and is reachable from the CLI or 20+ messaging platforms including Telegram, Discord, Slack, and WhatsApp.
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.
Both work with any OpenAI-compatible provider. Point the base URL at Standard Compute and get frontier-model compute with no usage limits from $39/mo flat — no per-token billing, no 429 rate limits.
