## 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

## TestSprite

TestSprite targets the gap between shipping code fast and knowing whether it still works. You point it at a project - giving it access to your code and product requirements for context - and it plans, generates, executes and reports on tests automatically. Runs happen against the deployed application rather than mocked dependencies, so a pass means a real person could actually complete the flow. Every session can be replayed as video, which makes evidence easy to attach to a pull request. Frontend, backend API and data flows are covered together.

Failures are treated as first-class output. Rather than a wall of red, TestSprite returns a single bundle containing the failing step and its neighbours, screenshots, DOM snapshots, the test source, a root-cause hypothesis and a suggested fix - enough for the developer or the coding agent that wrote the change to correct it and rerun. Auto-Heal repairs tests when the UI drifts, and tests are tied to a snapshot of the app rather than chasing moving state. Passing tests are retained as the app evolves, so coverage compounds instead of decaying between releases.

The platform meets teams wherever they work: an open-source CLI for coding agents and CI pipelines, an MCP server for the IDE, a merge gate that re-verifies pull requests and posts the result on the PR, and a no-code dashboard with project, test list, schedule and run-history views. Scheduled runs catch silent breakage between releases. Pricing starts with a free tier of 150 credits per month, then Starter at $19/mo (first month free), Standard at $39/mo, Pro at $69/mo and Enterprise from $199/mo, also sold on AWS Marketplace.

**Pricing & Plans:** Free tier with 150 credits/month for one app; Starter $19/mo (first month free), Standard $39/mo, Pro $69/mo for teams and Enterprise from $199/mo. Yearly billing saves 35%; also available on AWS Marketplace.

- **Tests the running app, not mocks:** Agents drive a real browser and live APIs like a user would, so a pass means the flow genuinely works end to end.
- **Failure bundles with a cause:** Each failure arrives with the failing step, screenshots, DOM snapshots, test source, root-cause hypothesis and a suggested fix.
- **Auto-Heal and compounding coverage:** Tests repair themselves when the UI drifts, and every passing test is kept so coverage grows with the app.
- **One engine, every surface:** The same verifier runs from an open-source CLI, an MCP server in your IDE, a CI merge gate, or a no-code dashboard.
- **Scheduled runs and merge gates:** Nightly, weekly or per-release schedules plus PR checks that block merges until the full suite passes, with results posted to the PR.

**Strengths:** Verifies real browsers and live APIs instead of mocked assertions; Failures arrive with evidence and a fix suggestion, cutting triage time; Integrates with CLI, MCP/IDE, GitHub PR checks and CI rather than replacing your workflow; Open-source CLI and a genuinely usable free tier lower the barrier to entry

**Limitations:** Credit-based limits mean larger suites or more frequent runs push you up a plan; Value depends on the app being reachable in a testable environment, so setup effort is unavoidable; Deeper enterprise features like SSO, audit logs and single-tenant deployment sit behind the top tier
