## 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

## teste.ai

Teste.ai is a Brazilian platform that packages a toolbox of AI-based testing utilities for software quality professionals. From a single requirement or a passage of documentation, it generates complete test plans with scenarios, test cases and step-by-step scripts, so testers spend less time writing specifications and more time on higher-value analysis. It also generates structured test data on demand and includes a generator that writes SQL queries for pulling specific data from a database based on a natural-language description.

The platform is designed to be test-type agnostic: functional, API, usability, security and performance testing are all supported, and you can apply techniques such as boundary value analysis from within the same workspace. Under the hood it uses OpenAI language models combined with prompts crafted specifically for quality work, and the vendor states that your inputs are not used for model training and that queries are stored in a private history you can delete.

Access requires signing up and choosing a plan, with a free starting tier that includes test case and step-by-step generators and paid Pro plans billed monthly or annually. The product is built by Paiva Software Engineering in São Paulo, Brazil, and content is primarily presented in Portuguese.

**Pricing & Plans:** Freemium with a free starting plan that includes core generators such as the test case and step-by-step generators, plus paid Pro subscription plans available monthly or annually and cancellable at any time.

- **Test case, scenario and step generator:** Create complete test plans with scenarios, test cases and step-by-step scripts from just a requirement or a snippet of your documentation.
- **Test data (massa) generation:** Generate structured test data on demand in the quantity and shape you need, without manual spreadsheet work.
- **Natural-language SQL query builder:** Describe what you need in plain language and Teste.ai writes the corresponding SQL query for locating specific test data in a database.
- **Support for many test types:** Coverage extends to API, functional, usability, security and performance testing, all documented from one place.
- **Quality-tuned AI prompts:** Uses OpenAI language models with prompts purpose-built for software quality, and logs your queries in a private history.

**Strengths:** Turns a single requirement into full test plans and cases; Purpose-built prompts remove the need to craft your own; Generates test data and natural-language SQL queries; Covers functional, API, security and performance testing

**Limitations:** Interface and content are predominantly in Portuguese, which may slow non-Portuguese speakers; Requires account signup and a plan to access the full toolkit; Output quality depends on the clarity of your requirements or documentation; No native offline mode; it is a cloud-based platform
