pi.dev vs Oh My Pi: long-running knowledge-backed agents or model exploration and experimentation?

pi.dev and Oh My Pi get compared in feature lists that ignore how teams actually work. This page is a decision memo: what each is for, what only one of them does well, and which should be your default.

pi.dev is a Terminal agent aimed at Long-running knowledge-backed agents (Free (BYO keys)). Oh My Pi is a Terminal agent aimed at Model exploration and experimentation (Free (BYO keys)).

Quick verdict

Default for most teams reading this angle: pi.dev — native scheduling / unattended jobs. Keep Oh My Pi as a specialist when its unique strengths matter.

Feature matrix

Scheduled / unattended work

If you only use an agent while you watch the terminal, you bought a chat wrapper. The split that matters here:

Only one side has native scheduling. Use the scheduled tool for overnight jobs; use the other for interactive fixes—not the reverse.

Unattended jobs need separate API keys, logs that survive terminal close, hard step/$ caps, and a human gate for force-push or prod changes.

Strengths (from product positioning)

pi.dev

Pros: Persistent knowledge graphs; Scheduled tasks; Background agents.

Cons: No git integration; No plugin system; Small community.

Oh My Pi

Pros: Largest model catalog; Vision and browser automation; Daily releases (v16+); LSP integration.

Cons: No built-in cron; Less polished TUI; Rapid changes can break configs.

Public adoption signals

Numbers below come from terminalblog’s adoption snapshots (npm/PyPI/GitHub when available). They change; treat them as relative, not marketing.

Install / source paths

pi.dev

• Check the project site / GitHub for current install steps (CLI packages change often).

Oh My Pi

• Source: can1357/oh-my-pi

Always confirm install commands on the upstream repo—package names move.

When to choose which

Choose pi.dev when

• Your main job is Knowledge-intensive long-running agent tasks
• You need built-in cron / scheduling (which Oh My Pi lacks in our matrix)
• You can live with: No git integration; No plugin system

Choose Oh My Pi when

• Your main job is Model experimentation and multi-model workflows
• You need vision / screenshot understanding or git integration or plugins / skills (which pi.dev lacks in our matrix)
• You can live with: No built-in cron; Less polished TUI

Use both when

• Interactive coding and long unattended jobs are different lanes on your team
• You are migrating and need a temporary dual stack
• Compliance needs a local-first path even if daily work is commercial

Three jobs to run before you standardize

1. Nightly job: schedule a repo chore (deps PR, flaky test triage). Prefer pi.dev. Use Oh My Pi only if a human is present to drive the session.

Record: default tool, specialist tool, and forbidden actions (e.g. no prod deploys without a human). Put that in AGENTS.md.

FAQ

Can I run pi.dev and Oh My Pi side by side?

Yes. Use separate worktrees or clones so they never write the same files concurrently.

Which is cheaper?

Both pricing lines are above. Model your spike week (tokens × retries × seats). See the pricing guide.

Does SWE-bench decide this?

pi.dev has no solid public SWE-bench in our dataset. Oh My Pi has no solid public SWE-bench in our dataset. Benchmarks under-predict IDE feel, Windows reliability, and cron ops.

Bottom line

Start with pi.dev for this decision (native scheduling / unattended jobs). Keep Oh My Pi when you need its unique strengths: vision / screenshot understanding, git integration, plugins / skills. Revisit when pricing, models, or your job mix changes.

Operator notes that usually get skipped

Permissions: Agents with shell access can delete work as easily as they write them. Prefer clear approval prompts and deny-by-default for network and production credentials. pi.dev and Oh My Pi both need an explicit policy for force-push, .env reads, and cloud deploys.

Windows vs macOS: Path separators, PowerShell vs bash, and orphaned child processes still decide winners more often than marketing benchmarks. Run the same three jobs on the OS your team ships on before you standardize on pi.dev or Oh My Pi.

Lockfiles: Never run two agents against the same package-lock / pnpm-lock / Cargo.lock concurrently. That failure mode looks like “the agent is dumb” when it is really shared mutable state. Give pi.dev and Oh My Pi separate worktrees.

Memory vs amnesia: pi.dev is positioned for Long-running knowledge-backed agents; Oh My Pi for Model exploration and experimentation. Long-running memory or knowledge features only pay off if you invest in what they store; otherwise you pay complexity for zero retention.

Escape hatch: Can you export history, pin versions, and keep working if a model vendor deprecates a SKU next quarter? Multi-provider (Yes vs Yes) and open source (Yes vs Yes) matter more here than any single benchmark number.

Team rollout: Pick one default (pi.dev), one specialist, document forbidden actions, and revisit quarterly. Tooling churn is faster than most internal standards documents.
