## 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

## TestCraft

TestCraft is a browser extension aimed at QA engineers, developers and manual testers who want a head start on test design. Rather than writing test cases from a blank page, you open the extension on a live web page, pick the element or region you care about, and let OpenAI language models propose a broad set of test ideas — positive, negative and scenario-based — grounded in the actual elements on the page.

The second half of the workflow is automation. Once you have a set of ideas you like, you can edit them to match your intended coverage and convert a selected idea into a ready-to-run script. TestCraft targets the most common frameworks — Playwright, Selenium and Cypress — and supports JavaScript, TypeScript, Python, C# and Java, so the output can usually slot into an existing suite without translation work.

TestCraft also inspects the analyzed page for accessibility issues and returns suggestions to improve them, which helps teams fold inclusivity checks into their normal test design instead of treating them as a separate audit. The extension is published as free and open-source software with a public issue tracker, and its developer has been responsive to bug reports from users.

**Pricing & Plans:** TestCraft is distributed as a free and open-source browser extension from the Chrome Web Store. Features that call OpenAI language models rely on API access, so your own OpenAI usage and any associated costs apply. No paid tiers or subscriptions are documented in the extension listing or its public repository.

- **AI test idea generation:** Generate comprehensive test ideas for a page by analyzing its elements with OpenAI language models, then refine them before use.
- **Multi-framework script generation:** Convert a selected test idea into a runnable script for Playwright, Selenium or Cypress, choosing your preferred language from JavaScript, TypeScript, Python, C# or Java.
- **Accessibility checks:** Scan the page under analysis for accessibility problems and get actionable suggestions to make the application more inclusive.
- **Idea to automation pipeline:** Turn AI-generated test ideas directly into automation and edit them along the way so generated scripts match your intended scenarios.
- **Element picker:** Pick elements on a live page to scope analysis to a specific part of the interface.

**Strengths:** Free and open-source, with a public GitHub issue tracker; Generates scripts for three major frameworks in five programming languages; Folds accessibility checks into the same workflow as test design; Lets you edit AI test ideas before turning them into automation

**Limitations:** Some earlier reviews report the Pick element feature failing or not capturing full element boundaries; Test ideas depend on your own OpenAI API key and quota, so usage costs sit outside the extension; Limited screen selection when picking elements for analysis; Does not cover API-level testing in the extension flow
