OmO is the working name of code-yeongyu/oh-my-openagent, a source-available CLI coding agent at roughly 70,000 stars that runs on senpi (its fork of the Pi harness) and bundles a memory system, CodeMode, multi-model ultracode, Anthropic subscription support, and a workflow-DAG side pane. **It is the scale-versus-trust test case of the Pi-derivative family: twice the stars of any other member of that family, with a mascot listed as the maintainer, a sponsor in the README, and a custom license that assigns different terms to different portions of the code.** ## What it is A terminal agent distributed through an install script (`get.omo.dev`), built on OmO 5.0's announced Pi base: the senpi fork contributes the harness core, and OmO layers a memory system, CodeMode execution, MCP support, multi-model ultracode (running several models on one task), and Anthropic subscription billing. Workflow visualization comes through omo-herdr-dag, a companion project that renders live OmO workflow DAGs in a Herdr side pane. The README is sponsor-supported (OpenGateway, an OpenAI-compatible gateway, is the backer) and states the project is maintained by Jobdori, an AI assistant persona. ## Status Massively starred and fast-moving: 69,986 stars, 5,750 forks, and 1,272 open issues as of 2026-10-13, pushed the day of this check, with release v5.1.32 published 2026-10-13. **The governance record is the caution: the repository moved from an organization that now 404s, the license is a custom per-portion document GitHub reports as NOASSERTION rather than any standard license, and the README names an AI assistant as the maintainer beside its sponsor, so the usual signals a 70,000-star project carries are absent or inverted.** Independent discussion exists but is thin for the scale: two 4-point Hacker News threads (May and September 2026) and no sustained third-party coverage found. Star History Chart ## Strengths - Capability breadth for a CLI agent: memory, CodeMode, MCP, multi-model execution, and subscription billing in one install script. - The Pi lineage gives it a working harness core rather than a from-scratch framework, and Pi upstream ideas flow through the fork. - Shipping velocity is genuine: a release published the day of verification and continuous pushes. - The Herdr DAG side pane gives long-running work a visible workflow graph, which most terminal harnesses lack entirely. - The size of the community is itself information: at this star count, breakage gets reported fast. ## Cautions - The license is the headline risk: a custom per-portion document with no standard identifier, so redistribution and internal-use rights must be read term by term before adoption. - Provenance is murky: the original organization 404s, the maintainer of record is an AI persona, and a sponsor's gateway product sits in the README funnel. - The misspelled third-party reference inside the license ("oh-my-opencode") suggests the text was adapted rather than written for this project, which is the kind of detail a lawyer will care about. - 1,272 open issues against a side-project maintenance story argues the issue tracker is a wish wall, not a backlog. - Thin independent coverage for the star count keeps the stars-ahead-of-discussion flag this section applies to Cabinet-class records. ## Pricing The code is free to install and the README advertises no paid plan; Anthropic subscription usage is billed by Anthropic under your own login, and the README's sponsor sells a separate gateway product. The license file, not a pricing page, is what actually constrains use. ## Compared to - [Pi](../pi/index.md): the upstream harness OmO forks; Pi is MIT, smaller, and explicit about its design, OmO is bigger and bundled. - [Oh My Pi](../oh-my-pi/index.md): the other large Pi derivative at about half OmO's scale, with a cleaner licensing story; the like-for-like alternative inside the family. - [OpenCode](../opencode/index.md): the vendor-neutral terminal harness with standard licensing; the safer default at any budget. ## Bottom line **Recommended for tinkerers who want the most bundled terminal agent available and will read the custom license and pin the version they audit.** Not for commercial use without legal review, for teams needing standard licensing and identifiable maintainers, or for anyone who wants upstream Pi rather than a fork. ## Changes - 2026-10-13 - Created. ## See also - [Harness Feature Matrix](../harness-feature-matrix/index.md) - the category comparison this note joins - [Pi](../pi/index.md) - the upstream harness senpi forks - [Oh My Pi](../oh-my-pi/index.md) - the cleaner-licensed Pi derivative at half the scale - [OpenCode](../opencode/index.md) - the standard-licensed vendor-neutral default - [The Agentic Development Environment Landscape](../../the-agentic-development-environment-landscape/index.md) - the tracker this section extends ## References - https://github.com/code-yeongyu/oh-my-openagent - repository, custom license file, stars, fork count, push activity, and the OmO 5.0 Pi-base announcement as of 2026-10-13 - https://github.com/code-yeongyu/oh-my-openagent/blob/dev/README.md - the README: memory, CodeMode, Anthropic subscriptions, ultracode, sponsors, and the maintainer persona statement - https://github.com/jc01rho/omo-herdr-dag - the companion workflow-DAG side-pane project - https://get.omo.dev/install.sh - the install endpoint behind the curl one-liner - https://news.ycombinator.com/ - Algolia search returned two 4-point threads (May and September 2026) as the recorded thin independent footprint
