A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
No-code AI regression and UI testing for web apps, straight from your browser
Capture clicks, typing, drag-and-drop, uploads, form submissions and navigation, then replay the whole scenario instantly without writing scripts.
AI-driven visual comparison detects subtle differences in layout, styling and rendered content between expected and actual UI states.
When element IDs or properties change, scripts fall back to alternate locators such as XPath, relative paths or element position to stay green.
Connect Sauce Labs, BrowserStack, LambdaTest or Testing Bot accounts to run the same recorded test on multiple browsers and platforms.
