Oh My Pi
Terminal-native coding agent with a native Rust core, hash-anchored edits, and the IDE wired into your shell
Hash-anchored editing is the real story: binding every edit to an xxHash32 content hash instead of a line number is why omp's code-modification pass rates hold up on large, messy repositories where line-based agents drift. The advisor model reviewing each turn, /review's P0–P3 verdicts, and time-traveling stream rules reinforce that — this is an agent built for people who audit diffs, not accept them. Pick it if you live in a terminal and want parallel subagents in isolated worktrees. Skip it if you want the GUI copilot experience of Cursor or GitHub Copilot.

Skip Oh My Pi if you want a graphical copilot bolted to an editor or a zero-configuration agent — this is a CLI harness you configure with files, provider keys, and LSP servers before it earns its keep.
Connect a paid model provider for daily work: omp itself routes to 40+ providers, so your real recurring bill is the provider's token spend, not the harness
omp's pricing model was not published on any page reachable in this research pass, so no tier comparison can be made honestly. Compare it instead on total cost of ownership: a terminal harness that drives 40+ providers is priced mostly by the model you route to, so a cheap/fast model like DeepSeek-V4-Flash keeps running costs low, while deep-reasoning models and 32-way subagent fan-out raise them. Evaluate it against GUI copilots on the cost of provider tokens plus the setup hours a CLI harness

About Oh My Pi
Oh My Pi (omp) is a terminal-first coding agent built on a native Rust core — an agentic harness with the IDE wired in, so LSP code intelligence and DAP debugging live inside your shell rather than a separate window. It runs natively on Windows without WSL, and installs via a one-liner through curl, Homebrew, Bun, PowerShell, or mise on macOS, Linux, and Windows. Run `omp` inside a project, describe the outcome you want, and it investigates the repository, edits files, runs your development tools, and keeps everything in a resumable session you can branch, fork, or share. Its signature mechanism is hashline, which anchors each edit to an xxHash32 content hash instead of a line number — the company cites a benchmark where Grok Code Fast went from 6.7% to 68.3% pass@1 while Grok 4 Fast output dropped 61%. Around that core sit 32 built-in tools, 40+ model providers, 53 LSP servers across 14 operations, DAP debugging with 28 operations and 14 bundled adapters, and Python/JavaScript eval kernels that support tool-calling. Workflow features lean deterministic: subagents in isolated worktrees up to 32 concurrent, an advisor model reviewing every turn, /review returning prioritized P0–P3 feedback with a verdict, time-traveling stream rules for mid-run correction, GitHub-as-filesystem via issue:// and pr:// paths, and mnemopi local memory in SQLite with embeddings and a graph. It suits terminal-heavy developers who want authority over their agent rather than a chat panel bolted to an editor. Hands-on reports in 2026 pair it with DeepSeek-V4-Flash and GPT-5.6 Luna. If you want a GUI copilot, this is the wrong shape entirely.
Behind the Verdict
Oh My Pi makes one structural bet and builds everything else around it: deterministic edits. Rather than asking a model to regenerate line numbers and hoping the patch lands, omp's hashline anchors each modification to an xxHash32 content hash of the target region. The effect is measurable — the vendor cites a benchmark where Grok Code Fast climbed from 6.7% to 68.3% pass@1 while Grok 4 Fast output dropped 61%. That combination (higher pass rates, lower token burn) is the reason to read past the homepage. The depth around that core is unusual for a terminal agent. 32 built-in tools, 53 LSP servers across 14 operations and DAP debugging with 28 operations and 14 bundled adapters mean code intelligence and a live debugger inside the same session as your shell. Subagents run in isolated worktrees up to 32 concurrent, so auditing several packages at once is a first-class flow rather than a hack. Python and JavaScript eval kernels support tool-calling directly. mnemopi persists memory across sessions in SQLite with embeddings and a graph, which matters more than it sounds — resumable work is only useful if the agent remembers what it learned. Governance features are where this diverges from most coding agents. An advisor model reviews every turn, /review returns prioritized P0–P3 feedback with a verdict, and time-traveling stream rules let you correct course mid-run instead of killing the session. GitHub acts as a filesystem through issue:// and pr:// paths. Collaboration runs over /collab with AES-256-GCM encryption. The costs are real. Everything here is CLI-first: install is a shell script (curl, brew, bun, ps1, mise), configuration is files, and 40+ providers plus 53 LSP servers plus plugins and SDK/RPC/ACP surfaces is a lot of surface to learn. Windows users get a native path with no WSL, which removes the usual tax, but the ceiling on setup effort is still higher than a zero-config tool. Compatibility with config from Cursor MDC, Cline, Codex and five more softens migration without eliminating it. Verdict: for terminal-heavy developers and teams running agents in CI/CD that need reviewable, hash-verified diffs, this is a serious option. For anyone who wants a graphical copilot or a managed cloud agent with a dashboard, it is the wrong shape entirely.

Real-world workflow fit
Concrete scenarios for the personas Oh My Pi actually fits — and what changes day-one when you adopt it.
Runs omp inside the project, asks it to find why the user-session test hangs and fix the root cause; omp inspects the repository through LSP code intelligence, applies a hash-anchored edit, then runs the smallest relevant test
Outcome: A verified fix with a diff they can expand via Ctrl+O and audit, plus the advisor model's review of the turn before they commit
Delegates independent audit tasks to subagents running in isolated worktrees (up to 32 concurrent), watches their progress, and steers them mid-run using time-traveling stream rules when one drifts
Outcome: Parallel audit results land in one resumable session instead of 32 separate terminals, with per-package findings they can review before merging
Points omp at issue:// and pr:// paths so GitHub acts as a filesystem, pulls a PR's context into the session, implements the change, and asks /review for prioritized P0–P3 feedback with a verdict
Outcome: Issue-to-merge loop stays inside the terminal, with a reviewable verdict on the change rather than a chat summary
Use Cases
- Fix the root cause of a hanging test, run the smallest relevant test, and explain the diff without leaving the terminal
- Refactor symbols safely across a large repository with hash-verified edits instead of line-number patches
- Debug multi-file Python projects using LSP-integrated code intelligence and DAP debugging
- Parallelize package audits or test generation across up to 32 subagents in isolated worktrees
- Triage and act on GitHub issues and pull requests through issue:// and pr:// paths in-session
- Run live pair-programming sessions over /collab with AES-256-GCM encryption
- Review an agent's change with a P0–P3 verdict before merging, then resume or branch the session later
Models Under the Hood
as of 2026-09-28
Limitations
- omp is a terminal-first agent: install is a shell one-liner (curl, brew, bun, ps1, mise) on macOS and Linux, with a separate Windows-native path that avoids WSL.
- The feature surface is genuinely large — 32 built-in tools, 53 LSP servers, DAP adapters, 40+ providers, subagents, MCP, plugins, and SDK/RPC/ACP programmatic surfaces — so expect meaningful configuration effort before it fits your team. omp can modify files and run commands in your environment, so review its work as you would a teammate's change and use approval controls for sensitive projects.
- Prompts and relevant context are sent to the model provider you select, and integrations may contact their corresponding services.

Where the pricing makes sense
The company stage and team size where Oh My Pi's pricing actually pencils out — and where peers do it cheaper.
omp's pricing model was not published on any page reachable in this research pass, so no tier comparison can be made honestly. Compare it instead on total cost of ownership: a terminal harness that drives 40+ providers is priced mostly by the model you route to, so a cheap/fast model like DeepSeek-V4-Flash keeps running costs low, while deep-reasoning models and 32-way subagent fan-out raise them. Evaluate it against GUI copilots on the cost of provider tokens plus the setup hours a CLI harness
Setup time & first value
How long it actually takes to get something useful out of Oh My Pi — broken out by persona, not the marketing-page minute.
If you already live in a shell, budget roughly 15–30 minutes to a first useful session: install via the one-liner, authenticate one provider, then open a project and run `omp` on a small task. For a team-standard setup — provider roles, project rules and skills, MCP servers, LSP servers for your languages, and approval policy — plan on a few hours. Windows users skip the WSL setup step entirely.
Switching to or from Oh My Pi
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Cursor: omp reads Cursor MDC config natively, so project rules carry over without rewriting them
- →From Cline: omp is config-compatible with Cline, so existing rule files transfer
- →From Codex: omp reads Codex config, letting you keep the same conventions in the terminal harness
- →From a chat-window assistant: start with one real repository task in a session rather than pasting snippets, and keep the work resumable
- ↗To Cursor or a GUI copilot: expect to restate project rules as editor configuration, since omp's reasoning lives in CLI session and file-based config
- ↗To a managed cloud agent: you lose local SQLite memory (mnemopi) and repo-local sessions, so export or share sessions first
