## 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

## Shiplight AI

Shiplight AI is an agent-native end-to-end testing platform built around the idea that tests should be authored and maintained by the same coding agents developers already use. It installs into tools like Claude Code, Cursor, Codex, VS Code and Antigravity, letting an agent walk your application in a real browser and generate tests written as plain-English YAML that describes user intent rather than CSS selectors. Those tests live in your repository and can be reviewed in a pull request like any other code change.

The platform emphasizes self-healing. When a cached locator goes stale — a button moves or a class is renamed — Shiplight re-reads the page, resolves the original intent with AI, and updates its cache mid-run, so intended UI changes do not break the suite while genuine regressions still fail loudly. Settled steps replay deterministically from a cache at full Playwright speed, meaning only new or changed screens cost a model call, so mature suites run faster and cheaper over time.

Shiplight also covers execution and triage: the same test file runs locally, on Shiplight-hosted CI runners, or on your own infrastructure, and results land on the pull request with logs, screenshots and traces. A fix workflow can reproduce a failure, find the cause and update the test. It is positioned as enterprise-ready with SOC 2 compliance, audit logs, private cloud/VPC deployment options, and a free starting tier. Pricing for teams is available on request.

**Pricing & Plans:** Shiplight AI offers a free plan to start, with hosted CI runners, result history and dashboards on paid tiers; enterprise and team pricing is available on request.

- **Browser MCP for coding agents:** Install Shiplight into Claude Code, Cursor, Codex, VS Code or Antigravity so your agent can drive a real browser and author tests.
- **Human-readable YAML tests:** Tests describe user intent in plain-language YAML committed to your repo, reviewable in pull requests and editable in a local debugger.
- **Self-healing test suites:** Stale locators are re-read and re-resolved with AI mid-run, so intended changes heal automatically while real bugs still fail.
- **Hosted and self-hosted runners:** The same test file runs locally, on Shiplight-hosted CI runners, or on your own infrastructure, with results posted to the PR.
- **Verify and review outside the suite:** The same browser skills verify a change the moment it is made and run structured accessibility, security and performance reviews.

**Strengths:** Tests authored and maintained by the coding agents teams already use; Self-healing keeps suites green through ordinary UI churn; Readable YAML tests live in the repo and are reviewable like code; Enterprise-ready with SOC 2, audit logs and private cloud options

**Limitations:** Value depends on adopting an agent-based developer workflow; Pricing is not published and requires contacting sales; Still requires a real browser environment for meaningful coverage
