The best Pi agent alternatives, checked 26 Oct 2026: OpenCode for another open source agent on any model, then Munder Difflin, free and open source: a desktop app that runs a team of AI agents for all kinds of knowledge work, coding included, on your own computer. Also: Claude Code, Codex CLI, Hermes Agent, Goose and Crush.

Why look for a Pi agent alternative?

Our view: people look past Pi when they want features in the box rather than features they build. Pi’s README, read on 26 Oct 2026, is clear about the trade:

  • Small on purpose. It calls Pi “a minimal, extensible agent harness that you can make your own”, and says it “skips features like sub-agents and plan mode”. You add them with extensions or packages.
  • No permission system. In its words: “Pi does not include a built-in permission system for restricting filesystem, process, network, or credential access.” It runs with your user’s permissions and points to containers or a sandbox for limits.
  • Terminal and code. Pi works in the terminal, in print or JSON mode, over RPC and through a TypeScript SDK. Chat apps, schedules and work beyond code need something else.

None of this is a flaw for people who like to build their own agent. Pi is MIT licensed, and release v1.4.0 shipped on 21 Oct 2026.

Pi skips subagents and plan mode and has no built in permission system, per its README on 26 Oct 2026.

Which Pi agent alternatives are worth a look?

Seven tools pass, each live with a release in October 2026.

1. OpenCode. OpenCode is “The open source AI coding agent”, MIT licensed, in the terminal and as a desktop app in beta, with release v1.19.4 on 22 Oct 2026. Its site lists “75+ LLM providers”, local models included, and says “OpenCode is 100% free to use” (26 Oct 2026). Best for: a fuller open source agent on any model. See OpenCode alternatives.

2. Munder Difflin. Keep Pi and add more agents. Munder Difflin is MIT licensed and runs Pi as one of its CLIs, next to Claude Code, Codex, OpenCode, Gemini CLI and Copilot. Each agent gets its own terminal, and they share a task board; the install guide covers setup. Best for: a team of agents for research, writing, ops and code.

3. Claude Code. Anthropic’s agent “reads your codebase, edits files, runs commands, and integrates with your development tools”, per its docs. It runs Claude models and has permission modes built in. Anthropic’s pricing page includes it in Pro, $20 if billed monthly, as of 26 Oct 2026. Best for: Claude with permissions built in.

4. Codex CLI. Codex CLI is “a coding agent from OpenAI that runs locally on your computer”, Apache 2.0. On ChatGPT plans the CLI starts at Plus, $20 a month, per OpenAI’s Codex pricing page on 26 Oct 2026. Best for: people who already pay for ChatGPT. See Codex alternatives.

5. Hermes Agent. Hermes Agent is “The self-improving AI agent built by Nous Research”, MIT licensed, release v0.22.5 on 23 Oct 2026. Its README says “Use any model you want”, lists a built in cron scheduler and subagents, and runs in Telegram, Discord, Slack, WhatsApp, Signal and the CLI. Best for: an agent that lives in your chat apps. See what is Hermes Agent.

6. Goose. Goose is “a general-purpose AI agent that runs on your machine”, as a desktop app and a CLI, and “works with 15+ providers”, Ollama included. Apache 2.0, release v1.56.0 on 23 Oct 2026. Best for: one agent for code and other work.

7. Crush. Crush from Charm is a terminal agent that lets you “switch LLMs mid-session while preserving context” and add tools through MCP. It uses the Functional Source License 1.1 with an MIT future licence, release v0.98.2 on 23 Oct 2026. Best for: a polished terminal agent with LSP context.

Can I keep Pi and use other agents too?

Yes. Munder Difflin is free and open source: a desktop app that runs a team of AI agents for all kinds of knowledge work, coding included, on your own computer. Pi is one of the CLIs it runs, next to Claude Code, Codex and OpenCode.

Which Pi alternative works outside the terminal?

Hermes Agent, Munder Difflin and Goose. Munder Difflin is a desktop app. Hermes Agent's README says it runs in Telegram, Discord, Slack, WhatsApp, Signal and the CLI from one gateway. Goose ships a desktop app and a CLI. Both checked 26 Oct 2026.
