## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI

## Refact.ai

Refact.ai is an AI coding agent designed to work like an extra developer on your team. Instead of just suggesting the next line, its agent plans a task, searches and analyzes your repository for relevant context, and then executes changes step by step with reasoning you can preview and control. It runs inside your IDE alongside a context-aware chat and fast autocompletion, and supports more than 25 programming languages across major editors including VS Code, JetBrains IDEs, Visual Studio, Neovim and Sublime Text.

What sets Refact apart is control over deployment and models. It can connect to tools such as GitHub, GitLab, Docker, PostgreSQL and MySQL so the agent can act on your real environment, and it lets you choose among leading LLMs or bring your own API key. For teams that cannot send code to a third party, the self-hosted and on-premise options keep the entire workflow — including the models — on your own infrastructure, and enterprise deployments can be fine-tuned on a company's specific stack.

Refact.ai is an open-source project maintained by Small Magellanic Cloud Ai Ltd. and has been recognized by Gartner as an open-source enterprise AI code assistant. One important update: the vendor has discontinued Refact Cloud, so the offering now focuses on self-hosted, SaaS-by-arrangement and enterprise deployments rather than a standard sign-up cloud plan. Pricing for those deployments is handled through sales conversations.

**Pricing & Plans:** Freemium / contact sales. The public cloud plan has been discontinued; the open-source version is available, and self-hosted and enterprise deployments are quoted through sales. Check the site for current details.

- **Autonomous coding agent:** A task-driven agent that plans work, searches your repository for context and executes changes step by step, connecting to GitHub, databases and CI/CD.
- **Context-aware chat and autocompletion:** In-IDE chat for asking, editing, debugging and generating code in natural language, plus fast multi-line autocompletion powered by RAG over your project.
- **Open-source and self-hosted:** Deploy on-premise or run the open-source version to keep your code private and fully under your own control.
- **Flexible model choice:** Pick from leading LLMs or bring your own API key, and fine-tune the agent on your company's coding style and stack.
- **Wide language and IDE support:** Works with 25+ programming languages across VS Code, JetBrains IDEs, Visual Studio (beta), Neovim (beta) and Sublime Text (beta).

**Strengths:** Open-source with on-premise and self-hosted options for full data control; Autonomous agent that plans, searches the codebase and executes tasks end-to-end; Support for 25+ languages across all major IDEs, with bring-your-own-key model choice; Integrations with GitHub, GitLab, Docker, PostgreSQL and more

**Limitations:** Refact Cloud has been discontinued, so the hosted sign-up option is no longer available; Self-hosted and enterprise deployments require setup and infrastructure effort; Clear public list pricing is not shown on the site, so costs come via sales discussions
